Summary edit

Description	English: MSL EDL Instrument (MEDLI) Suite The Mars Science Laboratory Entry, Descent, and Landing Instrument (MEDLI) Suite is a set of engineering sensors designed to measure the atmospheric conditions and performance of the MSL heatshield during entry and descent at Mars. The MEDLI suite consists of seven MEDLI Integrated Sensor Plugs (MISP) and seven Mars Entry Atmospheric Data System (MEADS) pressure sensors, located on the heatshield of the spacecraft. The picture shows a sensor MISP When the spacecraft faces extreme heat during entry into the Martian atmosphere, MISP measures how hot it gets at different depths in the spacecraft's heat-shield material. Predicted heating levels are about three times higher than those of the Space Shuttle when it enters Earth's atmosphere. The heating levels are so high, in fact, that the spacecraft's thermal protection system (TPS) is designed to burn away during entry into Mars' atmosphere. MISP will measure the rate of this burning, also known as "recession." When they designed the heat shield, engineers predicted what they thought the heating rate would be as a function of time. They will compare their predictions to the actual data collected by MISP. That information will help them learn how much heat-shield material will be needed to protect future Mars missions Polski: MEDLI MEDLI jest zestawem czujników przeznaczonych do pomiaru warunków atmosferycznych i wydajności osłony termicznej Mars Science Laboratory (MSL) podczas wejścia do atmosfery Marsa i zejścia na jego powierzchnię. Zestaw MEDLI składa się z siedmiu czujników (MISP) i siedmiu czujników ciśnienia (MEADS), zlokalizowanych na wewnętrznej stronie osłony termicznej statku kosmicznego. Na zdjęciu przedstawiony jest czujnik MISP kiedy statek kosmiczny przebywa w obliczu ekstremalnych temperatur podczas wejścia w atmosferę Marsa, czujniki MISP mierzą temperaturę występującą na różnych głębokościach materiału osłony termicznej statku kosmicznego. Przewidywane poziomy nagrzewania są około trzy razy wyższe niż te z wahadłowca, gdy wchodził w atmosferę ziemską. Poziomy temperatur są tak wysokie, że podczas przechodzenie przez atmosferę Marsa system ochrony termicznej zaprojektowany jest do spalania z dala od osłony. MISP mierzy tempo tego spalania, znane również jako "recesja". Podczas projektowania osłony termicznej, inżynierowie muszą przewidzieć jaki chcą osiągnąć współczynnik nagrzewania w funkcji czasu, ponieważ będą porównać swoje prognozy do rzeczywistych danych zebranych przez MISP. Ta informacja pomoże im dowiedzieć się, jak dużo materiału do budowy osłony cieplnej będzie potrzeba do ochrony przyszłych misji na Marsa.
