Description
English: Hayabusa re-entry filmed by Ames Research 2010-06-13 at 13:51 UT by a camera onboard NASA's DC-8 Airborne Laboratory. The glowing return capsule is seen forward of and below the main Hayabusa probe bus as the latter breaks up. The capsule continues leaving a wake after the main bus fragments have faded. This video is a maximum possible quality transcoding downsampled to 300 pixels width of the original to obtain a smaller size and lower bitrate of about 90 kbps.
