EDL (Entry Descent and Landing) on Mars is such a tricky thing because it has a thin enough atmosphere parachutes don't work well, but enough atmosphere that you have to take it into account when controlling/designing the landing module (hence Schiaparelli's complex aerothermodynamics testing).
This is also why NASA's Curiosity rover had such a complex "sky crane" system and why NASA is willing to provide SpaceX communications support in exchange for the EDL data of SpaceX's landing module (the Red Dragon mission).
- stouset 10y agoIs that just GIF artifacts, or can you actually see a shock front as the lander mockup passes in front of objects (particularly, the striped markers)? That's incredible!
- mickronome 10y agoThats a shockwave for sure, look at the timestamps, that thing is going very fast.
- mickronome 10y agoWanted to add that while it is hard to judge the speed, if it would happen to be subsonic then I guess it technically is a pressure front and not a shock front as it is when supersonic, if I've understood the distinction correctly.
