    This false-color mosaic of the central region of the Coma cluster combines infrared and visible-light images to reveal thousands of faint objects (green). Follow-up observations showed that many of these objects, which appear here as faint green smudges, are dwarf galaxies belonging to the cluster. Two large elliptical galaxies, NGC 4889 and NGC 4874, dominate the cluster's center. The mosaic combines visible-light data from the Sloan Digital Sky Survey (color coded blue) with long- and short-wavelength infrared views (red and green, respectively) from NASA's Spitzer Space Telescope.

    The sharpest image ever taken of the large "grand design" spiral galaxy M81 is being released today at the American Astronomical Society Meeting in Honolulu, Hawaii. This beautiful galaxy is tilted at an oblique angle on to our line of sight, giving a "birds-eye view" of the spiral structure. The galaxy is similar to our Milky Way, but our favorable view provides a better picture of the typical architecture of spiral galaxies. Though the galaxy is 11.6 million light-years away, NASA Hubble Space Telescope's view is so sharp that it can resolve individual stars, along with open star clusters, globular star clusters, and even glowing regions of fluorescent gas. The spiral arms, which wind all the way down into the nucleus, are made up of young, bluish, hot stars formed in the past few million years. They also host a population of stars formed in an episode of star formation that started about 600 million years ago. The greenish regions are dense areas of bright star formation. The ultraviolet light from hot young stars are fluorescing the surrounding clouds of hydrogen gas. A number of sinuous dust lanes also wind all the way into the nucleus of M81. The galaxy's central bulge contains much older, redder stars. It is significantly larger than the Milky Way's bulge. A black hole of 70 million solar masses resides at the center of M81. The black hole is about 15 times the mass of the Milky Way's black hole. Previous Hubble research shows that the size of the central black hole in a galaxy is proportional to the mass of a galaxy's bulge. M81 may be undergoing a surge of star formation along the spiral arms due to a close encounter it may have had with its nearby spiral galaxy NGC 3077 and a nearby starburst galaxy (M82) about 300 million years ago. Astronomers plan to use the Hubble image to study the star formation history of the galaxy and how this history relates to the neutron stars and black holes seen in X-ray observations of M81 with NASA's Chandra X-ray Observatory. M81 is one of the brightest galaxies that can be seen from the Earth. It is high in the northern sky in the circumpolar constellation Ursa Major, the Great Bear. At an apparent magnitude of 6.8 it is just at the limit of naked-eye visibility. The galaxy's angular size is about the same as that of the Full Moon. The Hubble data was taken with the Advanced Camera for Surveys in 2004 through 2006. This color composite was assembled from images taken in blue, visible, and infrared light.

    The "Mini Matterhorn" is a 3/4 meter rock immediately east-southeast of the Mars Pathfinder lander. This image, along with PIA00817 and PIA00818, shows how super resolution techniques can be applied to nearfield targets to help to address questions about the texture of the rocks at the landing site and what it might tell us about their modes of origin. This image shows a "raw", standard-resolution color frame of the rock. PIA00818 and PIA00819 were produced by combining the "Super pan" frames from the IMP camera. The composite color frame consists of 7 frames from the right eye, taken with different color filters that were enlarged by 500% and then co-added using Adobe Photoshop to produce, in effect, a super-resolution panchromatic frame that is sharper than an individual frame would be. Mars Pathfinder is the second in NASA's Discovery program of low-cost spacecraft with highly focused science goals.

    Barnacle Bill is a small rock immediately west-northwest of the Mars Pathfinder lander and was the first rock visited by the Sojourner Rover's alpha proton X-ray spectrometer (APXS) instrument. This image and PIA00820 show super resolution techniques applied to the first APXS target rock, which was never imaged with the rover's forward cameras. Super resolution was applied to help to address questions about the texture of this rock and what it might tell us about its mode of origin. These views of Barnacle Bill were produced by combining the "Insurance Pan" frames taken while the IMP camera was still in its stowed position on sol2. The composite color frame consists of 5 frames from the right eye, taken with different color filters that were enlarged by 500% and then co-added using Adobe Photoshop to produce, in effect, a super-resolution panchromatic frame that is sharper than an individual frame would be.

    This image is one frame of an animation that was created by using two mosaics: a color image of the Gallery Pan and an image which indicates the distance to the nearest object at each pixel location, referred to as a range image. The range data set is treated as a displacement map with respect to a sphere's surface, and the color image mosaic is draped onto the inside of the sphere. The position of the camera is fixed at the sphere's center, while its viewing direction is in this case looking at the south pole of the sphere. The mosaics were projected onto a continuous cylindrical/perspective coordinate system spanning 360 degrees of azimuth. The distortion visible near the edges of this image is due to the large field of view, as well as the limitation introduced by using cylindrically-projected images on the sphere - the effects of which are less apparent when smaller fields of view are used. The image has been rotated so that the main points of interest, which are the "Rock Garden," the rover Sojourner and the rock "Yogi," are easily seen arching across the upper hemisphere. In fixed Mars Surface coordinates, the top of the image looks out towards a point a few degrees north of West. Color has been enhanced to improve contrast in features, and is derived from IMP spectral filters 5, 9 and 0.

    Each of these panoramic views is a controlled mosaic of approximately 300 IMP images covering 360 degrees of azimuth and elevations from approximately 4 degrees above the horizon to 45 degrees below it. Simultaneous adjustment of orientations of all images has been performed to minimize discontinuities between images. Mosaics have been highpass-filtered and contrast-enhanced to improve discrimination of details without distorting relative colors overall. TOP IMAGE: Enhanced true-color image created from the "Gallery Pan" sequence, acquired on sols 8-10 so that local solar time increases nearly continuously from about 10:00 at the right edge to about 12:00 at the left. Mosaics of images obtained by the right camera through 670 nm, 530 nm, and 440 nm filters were used as red, green and blue channels. Grid ticks indicate azimuth clockwise from north in 30 degree increments and elevation in 15 degree increments. BOTTOM IMAGE: Anaglyphic stereoimage created from the "monster pan" sequence, acquired in four sections between about 8:30 and 15:00 local solar time on sol 3. Mosaics of images obtained through the 670 nm filter (left camera) and 530 and 440 nm filters (right camera) were used where available. At the top and bottom, left- and right-camera 670 nm images were used. Part of the northern horizon was not imaged because of the tilt of the lander. This image may be viewed stereoscopically through glasses with a red filter for the left eye and a cyan filter for the right eye.

    Planimetric (overhead view) map of the landing site, to a distance of 20 meters from the spacecraft. North is at the top in this and Plates 3-5. To produce this map, images were geometrically projected onto an assumed mean surface representing the ground. Features above the ground plane (primarily rocks) therefore appear displaced radially outward; the amount of distortion increases systematically with distance. The upper surfaces of the lander and rover also appear enlarged and displaced because of their height. Primary grid (white) is based on the Landing Site Cartographic (LSC) coordinate system, defined with X eastward, Y north, and Z up, and origin located at the mean ground surface immediately beneath the deployed position of the IMP camera gimbal center. Secondary ticks (cyan) are based on the Mars local level (LL) frame, which has X north, Y east, Z down, with origin in the center of the lander baseplate. Rover positions (including APXS measurements) are commonly reported in the LL frame. Yellow grid shows polar coordinates based on the LSC system.

    Overhead view of the area surrounding the Pathfinder lander illustrating the Sojourner traverse. Red rectangles are rover positions at the end of sols 1-30. Locations of soil mechanics experiments, wheel abrasion experiments, and APXS measurements are shown. The A numbers refer to APXS measurements as discussed in the paper by Rieder et al. (p. 1770, Science Magazine, see image note). Coordinates are given in the LL frame. The photorealistic, interactive, three-dimensional virtual reality (VR) terrain models were created from IMP images using a software package developed for Pathfinder by C. Stoker et al. as a participating science project. By matching features in the left and right camera, an automated machine vision algorithm produced dense range maps of the nearfield, which were projected into a three-dimensional model as a connected polygonal mesh. Distance and angle measurements can be made on features viewed in the model using a mouse-driven three-dimensional cursor and a point-and-click interface. The VR model also incorporates graphical representations of the lander and rover and the sequence and spatial locations at which rover data were taken. As the rover moved, graphical models of the rover were added for each position that could be uniquely determined using stereo images of the rover taken by the IMP. Images taken by the rover were projected into the model as two-dimensional "billboards" to show the proper perspective of these images.

    Topographic map of the landing site, to a distance of 60 meters from the lander in the LSC coordinate system. The lander is shown schematically in the center; 2.5 meter radius circle (black) centered on the camera was not mapped. Gentle relief [root mean square (rms) elevation variation 0.5 m; rms a directional slope 4O] and organization of topography into northwest and northeast-trending ridges about 20 meters apart are apparent. Roughly 30% of the illustrated area is hidden from the camera behind these ridges. Contours (0.2 m interval) and color coding of elevations were generated from a digital terrain model, which was interpolated by kriging from approximately 700 measured points. Angular and parallax point coordinates were measured manually on a large (5 m length) anaglyphic uncontrolled mosaic and used to calculate Cartesian (LSC) coordinates. Errors in azimuth on the order of 10 are therefore likely; elevation errors were minimized by referencing elevations to the local horizon. The uncertainty in range measurements increases quadratically with range. Given a measurement error of 1/2 pixel, the expected precision in range is ~ 0.3 meter at 10 meter range, and ~ 10 meters at 60 meter range. Repeated measurements were made, compared, and edited for consistency to improve the range precision. Systematic errors undoubtedly remain and will be corrected in future maps compiled digitally from geometrically controlled images. Cartographic processing by U.S. Geological Survey.

    Type areas of rocks and soils. (A) Dark rock type and bright soil type: Shown is the dark rock Barnacle Bill. Reflectance spectra typical of fresh basalt and APXS spectra indicating more silica-rich basaltic andesite compositions characterize this type. These rocks are typically the small boulders and intermediate-sized cobbles at the Pathfinder site. The bright soil type is very common and in this case comprises Barnacle Bill's wind tail and much of the surround soil area. This soil has a high reflectance and a strongly reddened spectrum indicative of oxidized ferric minerals. (B) Bright rock type: Shown is the bright rock Wedge. Reflectance spectra typical of weathered basalt and APXS spectra indicating basaltic compositions characterize this type. These rocks are typically larger than 1 meter in diameter and many display morphologies indicating flood deposition. (C) Pink rock type: Shown is the pink rock Scooby Doo. APXS and reflectance spectra indicate a composition and optical characteristics similar to the drift soil. However, the morphology of the pink rock type indicates a cemented or rocklike structure. This material may be a chemically cemented hardpan that underlies much of the Pathfinder site. (D) Dark soil type: The dark soil type is typically found on the windward sides of rocks or in rock-free areas like Photometry Flats (shown here) where the bright soil has been striped away by aeolian action or in open areas. Other locations include the Mermaid Dune. (E) Disturbed soil type: The darkening of disturbed soil relative to its parent material, bright soil, as a result of changes in soil texture and compaction caused by movement of the rover and retraction of the lander airbag. (F) Lamb-like soil type: This soil type shows reflectance and spectral characteristics intermediate between the bright and dark soils. Its distinguishing feature is a weak spectral absorption near 900 nanometers not seen in either the bright or dark soils.

    This figure contains an azimuth-elevation projection of the "Gallery Panorama." The original Simple Cylindrical mosaic has been reprojected to the inside of a sphere so that lines of constant azimuth radiate from the center and lines of constant elevation are concentric circles. This projection preserves the resolution of the original panorama. Overlaid onto the projected Martian surface is a delineation of the Sojourner rover traverse path during the 83 Sols (Martian days) of Pathfinder surface operations. The rover path was reproduced using IMP camera "end of day" and "Rover movie" image sequences and rover vehicle telemetry data as references.

    Barnacle Bill is a small rock immediately west-northwest of the Mars Pathfinder lander and was the first rock visited by the Sojourner Rover's alpha proton X-ray spectrometer (APXS) instrument. This image shows super resolution techniques applied to the first APXS target rock, which was never imaged with the rover's forward cameras. Super resolution was applied to help to address questions about the texture of this rock and what it might tell us about its mode of origin. This view of Barnacle Bill was produced by combining the "Insurance Pan" frames taken while the IMP camera was still in its stowed position on sol2. The composite color frames that make up this anaglyph were produced for both the right and left eye of the IMP. The right eye composite consists of 5 frames, taken with different color filters, the left eye consists of only 1 frame. The resultant image from each eye was enlarged by 500% and then co-added using Adobe Photoshop to produce, in effect, a super-resolution panchromatic frame that is sharper than an individual frame would be. These panchromatic frames were then colorized with the red, green, and blue filtered images from the same sequence. The color balance was adjusted to approximate the true color of Mars. The anaglyph view was produced by combining the left with the right eye color composite frames by assigning the left eye composite view to the red color plane and the right eye composite view to the green and blue color planes (cyan), to produce a stereo anaglyph mosaic. This mosaic can be viewed in 3-D on your computer monitor or in color print form by wearing red-blue 3-D glasses.

    This is a more recent "geometrically improved, color enhanced" version of the 360-degree "Gallery Pan", the first contiguous, uniform panorama taken by the Imager for Mars (IMP) over the course of Sols 8, 9, and 10. Different regions were imaged at different times over the three Martian days to acquire consistent lighting and shadow conditions for all areas of the panorama. In this version of the panorama, much of the discontinuity that was due to parallax has been corrected, particularly along the lower tiers of the mosaic containing the Lander features. Distortion due to a 2.5 degree tilt in the IMP camera mast has been removed. The IMP is a stereo imaging system that, in its fully deployed configuration, stands 1.8 meters above the Martian surface, and has a resolution of two millimeters at a range of two meters. The IMP has color capability provided by 24 selectable filters -- twelve filters per "eye". Its red, green, and blue filters were used to take this panorama. The three color images were first digitally balanced according to the transmittance capabilities of a specific high-definition TV device at JPL, and then enhanced via changes to saturation and intensity while retaining the hue. A threshold was applied to avoid changes to the sky. An MTF filter was applied to sharpen feature edges. At left is a Lander petal and a metallic mast which is a portion of the low-gain antenna. On the horizon the double "Twin Peaks" are visible, about 1-2 kilometers away. The rock "Couch" is the dark, curved rock at right of Twin Peaks. Another Lander petal is at left-center, showing the fully deployed forward ramp at far left, and rear ramp at right, which rover Sojourner used to descend to the surface of Mars on July 5. Immediately to the left of the rear ramp is the rock "Barnacle Bill", which scientists found be andesitic, possibly indicating that it is a volcanic rock (a true andesite) or a physical mixture of particles. Just beyond Barnacle Bill, rover tracks lead to Sojourner, shown using its Alpha Proton X-Ray Spectrometer (APXS) instrument to study the large rock "Yogi". Yogi, low in quartz content, appears to be more primitive than Barnacle Bill, and appears more like the common basalts found on Earth. The tracks and circular pattern in the soil leading up to Yogi were part of Sojourner's soil mechanics experiments, in which varying amounts of pressure were applied to the wheels in order to determine physical properties of the soil. During its traverse to Yogi the rover stirred the soil and exposed material from several centimeters in depth. During one of the turns to deploy Sojourner's Alpha Proton X-Ray Spectrometer, the wheels dug particularly deeply and exposed white material. Spectra of this white material show it is virtually identical to the rock "Scooby Doo", and such white material may underlie much of the site. Deflated airbags are visible at the perimeter of all three Lander petals. Mars Pathfinder is the second in NASA's Discovery program of low-cost spacecraft with highly focused science goals.

    The true color of Mars based upon three filters with the sky set to aluminance of 60. The color of the Pathfinder landing site is yellowish brown with only subtle variations. These colors are identical to the measured colors of the Viking landing sites reported by Huck et al. [1977]. This image was taken near local noon on Sol 10. A description of the techniques used to generate this color image from IMP data can be found in Maki et al., 1999. Note: a calibrated output device is required accurately reproduce the correct colors.

    This 8-image mosaic was acquired during the late afternoon (near 5pm LST, note the long shadows) on Sol 2 as part of the predeploy "insurance panorama" and shows the newly deployed rover sitting on the Martian surface. This color image was generated from images acquired at 530,600, and 750 nm. The insurance panorama was designed as "insurance" against camera failure upon deployment. Had the camera failed, the losslessly-compressed, multispectral insurance panorama would have been the main source of image data from the IMP. However, the camera deployment was successful, leaving the insurance panorama to be downlinked to Earth several weeks later. Ironically enough, the insurance panorama contains some of the best quality image data because of the lossless data compression and relatively dust-free state of the camera and associated lander/rover hardware on Sol 2.

    Figure 1-8. Original Soyuz probe and drogue docking system. The active unit (right) consisted of a probe and latches; the passive unit, a receiving cone, socket, and catches. The passive unit’s frustum was longer than the active unit’s because it was designed to accept the probe. The probe acted as a shock absorber. Its tip contained sensors which registered contact with the cone, disabled the active craft’s control system, and fired thrusters on the active craft to force the spacecraft together. The probe entered the socket at the apex of the cone, whereupon catches and a restraining ring locked it into place. Plugs and sockets in the rims of the docking units then established electrical and intercom connections between the spacecraft.21

Fluid, gas, and electrical connections are established through the collars. After the cosmonauts are certain the seal is airtight, they remove the probe and drogue units, forming a tunnel between spacecraft and station. At undocking, four spring push rods drive the spacecraft apart. If the latches fail to retract, the spacecraft can fire pyrotechnic bolts to detach from the station.

For docking, the spade-shaped guides of the extended active unit (right) and the retracted passive unit (left) interacted for gross alignment. The ring holding the guides shifted to align the active unit latches with the passive unit catches. After these caught, shock absorbers dissipated residual impact energy in the American unit; mechanical attenuators served the same function on the the Soviet side. The active unit then retracted to bring the docking collars together. Guides and sockets in the docking collars completed alignment. Four spring push rods drove the spacecraft apart at undocking. The passive craft could play a modified active role in undocking if the active craft could not complete the standard undocking procedure. Pyrotechnic bolts provided backup.

    This document was prepared by the Information Services Division, Information Systems Directorate, NASA Johnson Space Center, in response to the many requests for information on Soviet/Russian spaceflight received by the Scientific and Technical Information Center in the division’s Information Management Branch. We hope this document will be helpful to anyone interested in Soviet/Russian spaceflight. In particular, we hope it will provide new insights to persons working on the Shuttle-Mir missions and International Space Station Alpha. As a look at the sources listed at the end of each part will show, this work is based primarily on Russian sources, usually in English translation. Unfortunately, these sources often conflict. In this work preference is given to sources which contain abundant details, verifiable or otherwise; are corroborated in whole or in part by at least one other Russian source; and are the product of persons or organizations that can be expected to have intimate knowledge of the hardware and events described. This is an exciting time to study Soviet/Russian spaceflight. New light is thrown regularly on mysteries decades old. But there has not yet been time to tell all the old secrets. Because of this, new revelations still occur frequently. Most of this work will likely remain an accurate account; however, specific interpretations and details will as likely prove inaccurate as new information is revealed. So it is with any book on Soviet/Russian spaceflight written in this time of transition. Some readers may note what they perceive to be an undue emphasis on Soviet/Russian mission and hardware anomalies. This is partly a result of the document’s focus, which is, after all, on Soviet/Russian hardware history. (The reader will note that, where appropriate, U.S. anomalies are mentioned as well.) In addition, in the Soviet era, anomalies were often the chief (or only) way new information about secret hardware emerged. All countries have had their share of problems on the space frontier. Mention of anomalies in this document should not be construed as criticism of hardware or management in any country. This document is an updated and corrected edition of document JSC 26770 (October 1994). New material updates the Soyuz-TM, Progress-M, Mir Career, and Comparative Chronology sections to November 15, 1994. Sundry corrections and additions have been made at the suggestion of readers of the JSC edition or on the basis of information unavailable when the JSC edition was written. Readers should also note the addition of an index.

    This high-resolution image captured by the Mars Exploration Rover Opportunity's panoramic camera highlights the puzzling rock outcropping that scientists are eagerly planning to investigate. Presently, Opportunity is on its lander facing northeast; the outcropping lies to the northwest. These layered rocks measure only 10 centimeters (4 inches) tall and are thought to be either volcanic ash deposits or sediments carried by water or wind. Data from the panoramic camera's near-infrared, blue and green filters were combined to create this approximate, true-color image. The Outcrop in a Nutshell Figure 1 highlights various rock targets within the outcrop lining the inner edge of the small crater where the rover landed. Opportunity recently finished examining the rock dubbed "Last Chance," then rolled over to "Wave Ripple," a section of rock in the region nicknamed "The Dells." Tomorrow, March 6, 2004, Sol 41, the rover will take a series of "touch-and-go" microscopic images at "Wave Ripple," before heading to another rock region with targets named "Slick Rock" and "Berry Bowl."

The combined images are PIA01547 for the sky, and a portion of PIA01466 for the terrain. The sky image is a radiometrically correct, true-color sunset, with the sky near the Sun a pale blue color. The terrain image has been artistically adjusted to match the approximate time of day of the sky image (4:10 p.m. local solar time at the landing site) and to provide a seamless horizon. The two source images are composites of several frames from the Imager for Mars Pathfinder camera. Additional information is available in the captions for the original images.

    Tracks made by the Sojourner rover are visible in this image, taken by one of the cameras aboard Sojourner on Sol 3. The tracks represent the rover maneuvering towards the rock dubbed "Barnacle Bill." The rover, having exited the lander via the rear ramp, first traveled towards the right portion of the image, and then moved forward towards the left where Barnacle Bill sits. The fact that the rover was making defined tracks indicates that the soil is made up of particles on a micron scale. Mars Pathfinder was developed and managed by the Jet Propulsion Laboratory (JPL) for the National Aeronautics and Space Administration.

    One of the two forward cameras aboard the Sojourner rover took this image of the Sagan Memorial Station on Sol 25. The camera uses a fisheye lens which produces the illumination gradient in the sky on the western horizon. The angular resolution of the camera is about three milliradians (.018 degrees) per pixel, which is why the image appears grainy. Features seen on the lander include (from left to right): the Atmospheric Structure Instrument / Meteorology Package (ASI/MET) mast with windsocks; the low-gain antenna mast, the Imager for Mars Pathfinder (IMP) on its mast at center; the disc-shaped high-gain antenna at right, and areas of deflated airbags. The dark circle on the lander body is a filtered vent that allowed air to escape during launch, and allowed the lander to repressurize upon landing. The high-gain antenna is pointed at Earth.

    A close-up view of the rock "Moe" in the Rock Garden at the Pathfinder landing site. Moe is a meter-size boulder that, as seen from Sojourner, has a relatively smooth yet pitted texture upon close examination. Such a texture is seen on Earth on rocks that have been abraded by wind in a process that is analogous to sand blasting. This view of Moe shows two faces on the rock, one (left side of the rock) facing north-northeast and the other (right side) facing east. These two faces are thought to have been pitted and fluted by strong, "sand"- carrying winds from the northeast.

    This is the right image of a stereo pair taken by the Sojourner rover in the area behind the "Rock Garden" at the Pathfinder landing site and gives a view of the Martian surface not seen from the lander. Of note here are several dune-like ridges in the foreground. These features are less than a meter high but several meters wide. They are thought to be created by surface winds blowing right to left (approximately northeast to southwest). These features are called dunes, because of their asymmetry, although the rover has not examined the sediment within them. Such sediment on Earth would be sand-size grains less than 1 millimeter in diameter.
  •  
    This pair of images shows a broad view (upper image) and detailed close-up view (lower image) of the disturbed surface near and on Mermaid Dune. Seen slightly right of center in the upper image are two diggings by the rover's wheel. The uppermost rut is in the surface away from Mermaid and is considered to be typical of the surface at the landing site. The closer rut represents the surface at the base of Mermaid on the upwind side. The lower image is an enlargement of the disturbed Mermaid sediments plus those of the underlying substrate; that is, the ground upon which the dune lies. Seen in the close-up are at least two types of sediment, one that seems to be approximately 1.4 cm thick and forms piles with sides sloping at approximately 35 degrees, and another at least 3 cm deep composed of sediment that has a characteristic slope of 41 degrees when piled. It is apparent in the images that there is a size range of sediment present in the rut, sediment that ranges from a few millimeters in size down to below the resolution of the camera.

    This Sojourner rover image of the Cabbage Patch shows small rounded objects on the surface that are about 3-4 cm across. Some of these are within excavations, which are about 0.5 cm wide. Several questions arise about the pebbles: Why are they rounded? Where did they come from? What do they mean? Geologists use MULTIPLE WORKING HYPOTHESES when attempting to explain observations. Some hypotheses that could account for the pebbles are: 1. They were rounded during transport by waters of catastrophic floods and deposited on the Ares Vallis floodplain 2. They were rounded by wave action on an ancient Martian beach 3. They were rounded during glacial transport 4. They are glasses that were produced by melting during impact cratering. The glass was first ejected from the crater, then molded into spherical shapes or drops as it traveled through the atmosphere, and finally was deposited at the sites 5. They are spatter from lava flows 6. They are nodules brought up from the deep Martian interior by lava flows or pyroclastic eruptions. 7. They are concretions formed in sedimentary rocks 8. They came from ancient conglomerate rocks. The pebbles were rounded by water action and subsequently lithified into conglomerate rocks. Later, the waters of catastrophic floods transported the conglomerates and deposited them on the Ares floodplain. The pebbles were then freed from the rocks by weathering. 9. A combination of the above Mars Pathfinder is the second in NASA's Discovery program of low-cost spacecraft with highly focused science goals.

    This Rover image of "Shark" (upper left center), "Half Dome" (upper right), and a small rock (right foreground) reveal textures and structures not visible in lander camera images. These rocks are interpreted as conglomerates because their surfaces have rounded protrusions up to several centimeters in size. It is suggested that the protrusions are pebbles and granules.

    This anaglyph view of Chimp, south southwest of the lander, was produced by combining two right eye frames taken from different viewing angles by Sojourner Rover. One of the right eye frames was distorted using Photoshop to approximate the projection of the left eye view (without this, the stereo pair is painful to view). The left view is assigned to the red color plane and the right view to the green and blue color planes (cyan), to produce a stereo anaglyph mosaic.

    This anaglyph view of Souffle, to the left of Yogi, was produced by combining two right eye frames taken from different viewing angles by Sojourner Rover on Sol 21. One of the right eye frames was distorted using Photoshop to approximate the projection of the left eye view (without this, the stereo pair is painful to view). The left view is assigned to the red color plane and the right view to the green and blue color planes (cyan), to produce a stereo anaglyph mosaic.

    This image was taken by the Sojourner rover in the area behind the "Rock Garden" at the Pathfinder landing site and gives a view of the Martian surface not seen from the lander. Of note here are several dune-like ridges in the foreground. These features are less than a meter high but several meters wide. They are thought to be created by surface winds blowing right to left (approximately northeast to southwest). These features are called dunes, because of their asymmetry, although the rover has not examined the sediment within them.

    This rich galaxy cluster, catalogued as Cl 0024+17, is allowing astronomers to probe the distribution of dark matter in space. The blue streaks near the center of the image are the smeared images of very distant galaxies that are not part of the cluster. The distant galaxies appear distorted because their light is being bent and magnified by the powerful gravity of Cl 0024+17, an effect called gravitational lensing. Dark matter cannot be seen because it does not shine or reflect light. Astronomers can only detect its influence by how its gravity affects light. By mapping the distorted light created by gravitational lensing, astronomers can trace how dark matter is distributed in the cluster. While mapping the dark matter, astronomers found a dark-matter ring near the cluster's center. The ring's discovery is among the strongest evidence that dark matter exists. The Hubble observations were taken in November 2004 by the Advanced Camera for Surveys.

    Astronomers using NASA's Hubble Space Telescope have discovered a ghostly ring of dark matter that formed long ago during a titanic collision between two massive galaxy clusters. The ring's discovery is among the strongest evidence yet that dark matter exists. Astronomers have long suspected the existence of the invisible substance as the source of additional gravity that holds together galaxy clusters. Such clusters would fly apart if they relied only on the gravity from their visible stars. Although astronomers don't know what dark matter is made of, they hypothesize that it is a type of elementary particle that pervades the universe. This Hubble composite image shows the ring of dark matter in the galaxy cluster Cl 0024+17. The ring-like structure is evident in the blue map of the cluster's dark matter distribution. The map was derived from Hubble observations of how the gravity of the cluster Cl 0024+17 distorts the light of more distant galaxies, an optical illusion called gravitational lensing. Although astronomers cannot see dark matter, they can infer its existence by mapping the distorted shapes of the background galaxies. The map is superimposed on a Hubble Advanced Camera for Surveys image of the cluster taken in November 2004.

    This image, taken by Deep Space 1 on September 22, 2001, has been enhanced to reveal dust being ejected from the nucleus of comet Borrelly. As a result, the nucleus, which is about eight kilometers (about five miles) long, is bright white in the image. The main dust jet is directed towards the bottom left of the frame, around 35 degrees away from the comet-Sun line. The jet emerges as actually comprised of at least three smaller features. This active region as a whole is at least three kilometers (less than two miles) long. Another, smaller, jet feature is seen on the tip of the nucleus on the lower right-hand limb. Dust also seems to be ejected from there into the night-side hemisphere, probably from the dayside hemisphere. The expansion of the gas and dust mixture into the vacuum of space has swept some material around the body of the nucleus so that it appears above the night-side hemisphere. The night-side of the nucleus could not be seen, of course. The line between day and night on the comet is towards the upper right. This representation shows a faint ring of brightness separated from the terminator by a dark, unlit area. It is possible that this is a crater rim, seen in grazing illumination, which is just about to cross into darkness as the comet rotates. The direction to the Sun is directly downwards. Deep Space 1 completed its primary mission testing ion propulsion and 11 other advanced, high-risk technologies in September 1999.

    Over 1300 energy spectra taken on September 22, 2001 from the ion and electron instruments on NASA's Deep Space 1 span a region of 1,400,000 kilometers (870,000 miles) centered on the closest approach to the nucleus of comet Borrelly. A very strong interaction occurs between the solar wind (horizontal red bands to left and right in figure) and the comet's surrounding cloud of dust and gas, the coma. Near Deep Space 1's closest approach to the nucleus, the solar wind picked up charged water molecules from the coma (upper green band near the center), slowing the wind sharply and creating the V-shaped energy structure at the center.

    Deep Space 1 flew by comet Borrelly on September 22, 2001 and took these measurements with its plasma instruments between 90,000 kilometers (56,000 miles) and 2,000 kilometers (1,200 miles) away. These data show that the flow of ions around the comet's rocky, icy nucleus (the center of the deep V-shaped feature) is not centered on the comet's nucleus as scientists expected before the Borrelly flyby. Ions in the turbulent flow are heated to about 1 million Kelvin (2 million degrees Fahrenheit) causing the bands of ions to appear broad and jagged compared to the solar wind.

    This very long exposure was taken by NASA's Deep Space 1 to show detailed structures in the faint parts of comet Borrelly's inner coma. As a result, the nucleus has been greatly over-exposed and its shape appears distorted. The main jet extends to the lower right about 30 degrees off the Sun-line. Faint structures in the coma stretch from the nucleus in all directions. The surface of Borrelly is composed of a mixture of dust and water ice, and as the comet approaches the Sun the ice sublimes. Dust carried outward by expanding gas makes the jets visible. Deep Space 1 completed its primary mission testing ion propulsion and 11 other advanced, high-risk technologies in September 1999.

    The solid nucleus of comet Borrelly is barely resolved in this image, enhanced to reveal the highly collimated dust extending towards the bottom left corner of the picture. The jet is attributed to dust carried outward by gas expanding outwards into a cone about 20 degrees across. The surface of Borrelly is composed of a mixture of dust and water ice, and as the comet approaches the Sun the water ice sublimes. The gases produced inside the comet by the Sun's heating race away from the surface into the vacuum of space, carrying the dust away with them. The jet was also seen in images acquired around 9 hours earlier. This suggests that the emission is coming from close to the rotation axis at the comet's constantly illuminated pole.

    A composite of images from NASA's Deep Space 1 spacecraft shows features of comet Borrelly's nucleus, dust jets escaping the nucleus and the cloud-like "coma" of dust and gases surrounding the nucleus. False color is used to reveal details of the jets and coma. The images were taken when Deep Space 1 was about 4,800 kilometers (3,000 miles) from Borrelly during a Sept. 22, 2001, flyby. Borrelly's nucleus is about 8 kilometers (5 miles) from end to end, so the field of view is about 40 kilometers (25 miles) across. The Sun shines from the bottom of the image. The main dust jet, seen extending toward the bottom left, heads away from the comet in a direction that is about 30 degrees off the direction straight toward the Sun from the comet. The colors show about three orders of magnitude in the brightness of the dust jets and coma. Red indicates about one-tenth the brightness as the brightness of the nucleus, blue one-one-hundredth, purple one-one-thousandth. The red bumps near the nucleus indicate where the jet resolves into three distinct, narrow jets, which likely come from discrete source points on the surface.

NASA extended the mission, taking advantage of the ion propulsion and other systems to undertake this encounter with the comet. More information can be found on the Deep Space 1 home page. Deep Space 1 was launched Oct. 24, 1998, as part of NASA's New Millennium Program, which is managed by JPL for NASA's Office of Space Science, Washington, D.C.

    This image of a xenon ion engine prototype, photographed through a port of the vacuum chamber where it was being tested at NASA's Jet Propulsion Laboratory, shows the faint blue glow of charged atoms being emitted from the engine. The engine is now in an ongoing extended- life test, in a vacuum test chamber at JPL, and has run for almost 500 days (12,000 hours) and is scheduled to complete nearly 625 days (15,000 hours) by the end of 2001. A similar engine powers the New Millennium Program's flagship mission, Deep Space 1, which uses the ion engine in a trip through the solar system. The engine, weighing 17.6 pounds (8 kilograms), is 15.7 inches (40 centimeters) in diameter and 15.7 inches long. The actual thrust comes from accelerating and expelling positively charged xenon atoms, or ions. While the ions are fired in great numbers out the thruster at more than 110,000 kilometers (68,000 miles) per hour, their mass is so low that the engine produces a gentle thrust of only 90 millinewtons (20-thousandths of a pound).

    This image of a xenon ion engine, photographed through a port of the vacuum chamber where it was being tested at NASA's Jet Propulsion Laboratory, shows the faint blue glow of charged atoms being emitted from the engine. The ion propulsion engine is the first non-chemical propulsion to be used as the primary means of propelling a spacecraft. Though the thrust of the ion propulsion is about the same as the downward pressure of a single sheet of paper, by the end of the mission, the ion engine will have changed the spacecraft speed by about 13,700 kilometers/hour (8500 miles/hour). Even then, it will have expended only about 64 kg of its 81.5 kg supply of xenon propellant.

    Veteran Spacecraft Attempts to Earn Extra Credit at Comet Like a slugger trying to pile up extra home runs after breaking the world record, a venerable NASA spacecraft already famed for bringing science fiction's ion-engine technology to life is preparing to fly daringly close to a comet on Saturday, Sept. 22. Deep Space 1, which has already completed a highly successful mission testing a number of advanced spacecraft technologies, will attempt to pass inside the mostly unknown environment just 2,000 kilometers (about 1,200 miles) from the nucleus of comet Borrelly at 2230 Universal time (3:30 p.m. PDT) on Sept. 22. "It has been a tremendously rewarding effort for the small Deep Space 1 team to keep this aged and wounded bird aloft," said Dr. Marc Rayman, project manager of Deep Space 1 at NASA's Jet Propulsion Laboratory, Pasadena, Calif. "Its mission to test new technologies is already highly successful and any science we get at the comet will be a terrific bonus." By the time of the flyby Deep Space 1 will have completed three times its intended lifetime in space and its primary mission to test ion propulsion and 11 other high-risk, advanced technologies in September 1999. NASA extended the mission, taking advantage of the ion propulsion and other systems to target a chancy but exciting encounter with Borrelly. The spacecraft may tell us more about comets and their place in the solar system. The robotic explorer will attempt to investigate the comet's environment when it tries to fly through the cloud of gas and dust surrounding the comet's nucleus, known as the coma. The risks involved in gathering science data are very high, so results of this latest venture are unpredictable. The spacecraft will be traveling through a cloud of gas, dust and comet pieces to collect its data. Since Deep Space 1 wasn't built to go to a comet, it does not carry a protective shield. "We expect to be hit by debris from the comet, and at 16.5 kilometers per second (about 36,900 mph), even a tiny particle might prove fatal," said Rayman. "But this is an adventure too exciting to pass up." If all goes well, scientists will use the comet chaser's measurements to find out the nature of Borrelly's surface and to measure and identify the gases coming from the comet. The spacecraft will also attempt to measure the interaction of solar wind with the comet, a process that leads to formation of the beautiful tail. Borrelly makes a good target for study now, as it is just 1.34 astronomical units (about 200 million kilometers or 125 million miles) from the Sun -- the closest it will get for another seven years. The Sun's heat will make the gases escaping from the nucleus flow faster and more thickly, so they will be easier to study. The icy nucleus and the spacecraft will flash past each other at 16.5 kilometers per second (more than 36,900 miles per hour). The flight team is also hoping that Deep Space 1 will have enough gas to get to the comet. The long-lived spacecraft keeps itself pointed correctly by firing small thrusters fueled by hydrazine gas. When the hydrazine runs out, Deep Space 1 will be unable to keep itself pointed correctly, and the spacecraft will die. The flight team has an estimate of how much gas is left, but a few hours' worth of gas could make all the difference in the comet encounter. As it approaches the center of the coma, the spacecraft will face its greatest challenge: to obtain pictures and infrared measurements of the nucleus. Deep Space 1 can't tell exactly where the nucleus is or what it will look like. The craft will have to locate the nucleus on its own and try to point the camera toward it as it streaks by. In late 1999, Deep Space 1 lost its star tracker, which helps determine the spacecraft's orientation. Faced with what could have been a mission-terminating injury, the controllers performed a spectacular ultra-long-distance rescue. They reconfigured the spacecraft to use the photographic camera to orient itself by the stars around it. The camera cannot align the spacecraft and snap photos of Borrelly at the same time. Instead, Deep Space 1 will have to rely on its fiber-optic gyroscopes to help maintain its orientation. But the gyros are not accurate enough by themselves, so engineers designed complex new software to help the camera stay pointed at the comet's nucleus during the critical few minutes that the probe will be close enough to try to get a view of it. More information can be found online at http://nmp.jpl.nasa.gov/ds1/http://nmp.jpl.nasa.gov/ds1/ Deep Space 1 was launched in October 1998 as part of NASA's New Millennium Program, which is managed by JPL for NASA's Office of Space Science, Washington.

    An ion thruster is removed from a vacuum chamber at NASA's Jet Propulsion Laboratory, Pasadena, Calif., its job done following almost five years of testing. Engineers John Anderson and Keith Goodfellow, from left, are part of JPL's Advanced Propulsion Technology Group. The thruster, a spare engine from NASA's Deep Space 1 mission, ran for a record 30,352 hours, giving researchers the ability to observe its performance and wear at different power levels throughout the test. This information will be vital to future missions that use ion propulsion. Ion propulsion systems can be very lightweight, running on just a few grams of xenon gas a day. This fuel efficiency can lower launch vehicle costs. Xenon is the same gas that is found in photo flash bulbs. The very successful Deep Space 1 mission featured the first use of an ion engine as the primary means of propulsion on a NASA spacecraft. NASA's next-generation ion propulsion efforts are led by the In-Space Propulsion Program, managed by the Office of Space Science at NASA Headquarters, Washington, D.C., and implemented by the Marshall Space Flight Center, Huntsville, Ala.. The program seeks to develop advanced propulsion technologies that will help near and mid-term NASA science missions by significantly reducing cost, mass or travel times. JPL is managed by the California Institute of Technology, Pasadena, Calif., for NASA.

    One of the two pictures of Tempel 1 (see also PIA02101) taken by Deep Impact's medium-resolution camera is shown next to data of the comet taken by the spacecraft's infrared spectrometer. This instrument breaks apart light like a prism to reveal the "fingerprints," or signatures, of chemicals. Even though the spacecraft was over 10 days away from the comet when these data were acquired, it detected some of the molecules making up the comet's gas and dust envelope, or coma. The signatures of these molecules -- including water, hydrocarbons, carbon dioxide and carbon monoxide -- can be seen in the graph, or spectrum. Deep Impact's impactor spacecraft is scheduled to collide with Tempel 1 at 10:52 p.m. Pacific time on July 3 (1:52 a.m. Eastern time, July 4). The mission's flyby spacecraft will use its infrared spectrometer to sample the ejected material, providing the first look at the chemical composition of a comet's nucleus. These data were acquired from June 20 to 21, 2005. The picture of Tempel 1 was taken by the flyby spacecraft's medium-resolution instrument camera. The infrared spectrometer uses the same telescope as the high-resolution instrument camera.

    This movie of comet Tempel 1 is made up of raw images taken by the medium resolution imager on the Deep Impact spacecraft. The images were acquired between June 22 and June 24, 2005. A brightening by a factor of about 5 and a rapid decay to baseline brightness were observed on June 22. As the comet moves through space, background stars pass in and out of the field of view. Cosmic rays hitting the spacecraft's detector give an appearance of flickering. This is an artifact of space cameras that can be removed.

    This animation chronicles the travels of NASA's Deep Impact spacecraft, from its launch in January of 2005 to its dramatic impact 172 days later with comet Tempel 1. The times listed below were updated on July 2, 2005, and differ from those referred to in the animation. The final phase of the mission, called the encounter phase, includes two targeting maneuvers, the last of which occurs at 5:07 p.m. Pacific time (8:07 p.m. Eastern time), July 2. Six hours later, the spacecraft releases an impactor into the path of the charging comet. Twelve minutes later, the remaining craft, called the flyby, steers itself away from the comet's path. The free impactor then autonomously fine-tunes its trajectory, with the goal of hitting the sunlit side of Tempel 1. Impact is scheduled to occur at 10:52 p.m. Pacific time, July 3 (1:52 a.m. Eastern time, July 4). The flyby spacecraft will watch the collision from the sidelines, snapping pictures up to 13 minutes after impact. At that point, the craft stops taking images and enters a protective mode, in which its shields block dust from the comet's inner coma. Fifty-nine minutes after impact, the flyby turns around for one last photo opportunity.

    This false-color image shows comet Tempel 1 as seen by Chandra X-ray Observatory on June 30, 2005, Universal Time. The comet was bright and condensed. The X-rays observed from comets are caused by an interaction between highly charged oxygen in the solar wind and neutral gases from the comet. The observatory detected X-rays with an energy of 0.3 to 1.0 kilo electron Volts. The bulk of the X-rays were between 0.5 and 0.7 kilo electron Volts. Chandra will observe the comet for 18 hours during and after the time when NASA's Deep Impact impactor probe collides with Tempel 1 at 10:52 p.m. Pacific time, July 3 (1:52 a.m. Eastern time, July 4). The material ejected from the crater could cause the interaction region, and thus the X-ray emission, to move toward the Sun.

  •  
    When NASA's Deep Impact probe collided with Tempel 1, a bright, small flash was created, which rapidly expanded above the surface of the comet. This flash lasted for more than a second. Its overall brightness is close to that predicted by several models. After the initial flash, there was a pause before a bright plume quickly extended above the comet surface. The debris from the impact eventually cast a long shadow across the surface, indicating a narrow plume of ejected material, rather than a wide cone. The Deep Impact probe appears to have struck deep, before gases were heated and explosively released. The impact crater was observed to grow in size over time. A preliminary interpretation of these data indicate that the upper surface of the comet may be fluffy, or highly porous. The observed sequence of impact events is similar to laboratory experiments using highly porous targets, especially those that are rich in volatile substances. The duration of the hot, luminous gas phase, as well as the continued growth of the crater over time, all point to a model consistent with a large crater. This image was taken by Deep Impact's medium-resolution camera.

    This image shows how Deep Impact's impactor targeted comet Tempel 1 as the spacecraft made its final approach in the early morning hours of July 4, Eastern time. The autonomous navigation system on the probe was designed to make as many as three impactor targeting maneuvers, identified as ITMs in this picture, to correct its course to the comet. The upper left dot indicates where the probe would have passed the comet's nucleus if no maneuvers were performed. The dot below the nucleus shows where the probe would have flown past the comet if only the first maneuver was made. The leftmost dot on the nucleus marks the spot where the probe would have crunched the comet if only the first two maneuvers had been performed. The lower dot on the nucleus indicates the vicinity where, once the third maneuver was performed, the probe met its final reward and collided with the comet.

    This image of the surface of comet Tempel 1 was taken about 20 seconds before Deep Impact's probe crashed into the comet at 10:52 p.m. Pacific time, July 3. This particular region contains the impact site. The bright patches in the image may consist of very smooth and reflective material, the composition of which will be determined by Deep Impact's spectrometer. Dark areas are in shadow and provide information about surface topography. Higher terrain appears rough relative to lower areas that appear very smooth. Is this a layered surface? And how did the smooth regions form? These are some of the questions the science team plans to address. This image was taken by the probe's impactor targeting sensor.

    This false-color image shows comet Tempel 1 about 50 minutes after Deep Impact's probe smashed into its surface. The impact site is located on the far side of the comet in this view. The image was taken by the mission's flyby spacecraft as it turned back to face the comet for one last photo opportunity. The colors represent brightness, with white indicating the brightest materials and black showing the faintest materials. This brightness is a measure of reflected sunlight. Because the sunlit portion of the comet is brighter, it appears white. The comet's nucleus is silhouetted against the light reflected from surrounding dust. The large plume of dust that was kicked up upon impact can be seen as the colorful, drop-shaped object. This plume was very bright, indicating that the comet's surface material must be very fine, like talcum powder. The blue speck in the upper left corner is a star. This picture was taken by Deep Impact's high-resolution camera.

These pictures were taken by the flyby craft's high-resolution camera over a period beginning 50 minutes after impact, and ending about 12 hours after impact. Impact occurred at 10:52 p.m. Pacific time, July 3, 2005.

    The image depicts the first moments after Deep Impact's probe interfaced with comet Tempel 1. The illuminated -- and possibly incandescent -- debris is expanding from the impact site. The rough-hewn edges at the top and bottom of the flash are a result of light given off at impact saturating some of the pixels in the camera's imager. The pixels "bleed" excess electronic charge onto adjacent pixels in the same column. This image was taken by Deep Impact's high-resolution camera.

    A temperature map of the nucleus with different spatial resolutions. The context image (in black and white) is a HRIVIS image taken just before impact. The color bar in the middle gives temperature in Kelvins. The sun is to the right in all images. These data were acquired with the IR spectrometer using signal between 1.8 and 2.2 µm and modeled to contain both a reflected and an emitted component. After this model is applied, the resulting number is a temperature which is represented by different colors with red being the highest and purple the coldest. The derived temperature varies from 260 +/- 6K to 329 +/- 8K. Shadows are the coolest temperatures, and the point directly below the sun is hottest. These temperatures indicate that the thermal inertia of the surface (the quality of the surface describing the ability to conduct and store heat) is low. In other words, on Tempel 1, it is hot in the sun and cold in the shadows. A value for thermal inertia is estimated at <100 W/K/m2/s1/2.

    These artist's concepts of Tempel 1 simulate an optical view of the comet (left), next to the simulated infrared view (right). The images illustrate the comet's shape, reflectivity, rotation rate and surface temperature, based on information from NASA's Hubble Space Telescope and Spitzer Space Telescope. Measurements from the Great Observatories indicate that the comet is a matte black object roughly 14 by 4 kilometers (8.7 by 2.5 miles), or about one-half the size of Manhattan. At the time of these early observations, March 25-27, 2005,Tempel 1 was still far enough away from the Sun that it had not yet developed its characteristic halo of evaporating gas. Hubble and Spitzer observed the comet in visible and infrared light, respectively. The comet appeared only as an unresolved dot due to the great distance, but its general shape, size and color could be deduced from the way the visible and infrared brightness varied over time. The animation simulates an optical view of the comet, followed by its appearance in infrared. Spitzer detects the comet's infrared energy or heat, depicted by the reddish glow. The movement of the comet has been dramatically sped up to 13 seconds per rotation versus its normal rotation of about 40 hours. As the comet slowly rotates, the sunlit side heats up while the dark side cools down.

    This Jan. 13 photograph was taken by Mt Palomar's 200-inch telescope as the Deep Impact spacecraft was at a distance of about 260,000 kilometers (163,000 miles) from Earth and moving at a speed of about 16,000 kilometers per hour (10,000 miles per hour). The high speed of the spacecraft causes it to appear as a long streak across the sky in the constellation Virgo during the 10-minute exposure time of the image. The spacecraft will travel to comet Tempel 1 and release an impactor, creating a crater on the surface of the comet. Scientists believe the exposed materials may give clues to the formation of our solar system.

Impact with comet Tempel 1 is planned for July 4, 2005.

    Sixty-nine days before it gets up-close-and-personal with a comet, NASA's Deep Impact spacecraft successfully photographed its quarry, comet Tempel 1, at a distance of 39.7 million miles. The image, taken on April 25, 2005, is the first of many comet portraits Deep Impact will take leading up to its historic comet encounter on July 4.
  •  
    On Monday, April 25, the Deep Impact spacecraft obtained its first optical navigation (Op-Nav) image of comet Tempel 1. At the time the picture was taken the distance between spacecraft and comet was 64 million kilometers (39.7 million miles) away. The exposure -- known as a "negative image" -- is used by the spacecraft team to assist in navigation and instrument calibration. The spacecraft will start imaging the comet on a regular basis in about 10 days.
  •  
    This image is a compilation of four images that were taken on June 13, 2005, through the clear filter of the medium resolution imager camera. The spacecraft is 18,675,137.9 kilometers (11,604,190 miles) away from comet Tempel 1, and the Sun is located to the right of the image.

    M81 and Holberg IX are located approximately 12 million light-years away in the northern constellation Ursa Major. In addition to leading the GALEX observations of M81, Huchra and his team also took observations of the region with NASA's Spitzer and Hubble space telescopes. By combining all these views of M81, Huchra hopes to gain a better understanding about how M81 has developed into the spiral galaxy we see today.

    Launching of the Little Joe launch vehicle on October 4, 1959 took place at Wallops Island, Va. This was the first attempt to launch an instrumented capsule with a Little Joe booster. Only the LJ1A and the LJ6 used the space metal/chevron plates as heat reflector shields, as they kept shattering. Little Joe was used to test various components of the Mercury spacecraft, such as the emergency escape rockets.
