I am so enthusiastic about the (proposed) Mars2020 camera suite during EDL, as presented today at IPPW:
- 3 PointGrey Chameleon 3 that will be on the skycrane and look up, to monitor parachute deployment at 150 fps. - 1 GoPro Hero 4 on the skycrane, looking down to monitor the rover descent and landing - 1 GoPro Hero 4 on the rover, looking up to monitor the skycrane and fly-away - 1 GoPro Hero 4 on the rover, looking down like MARDI did on Curiosity - MARDI, of course. All GoPro have microphone that will be activated, and have been tested successfully in the proper thermal and radiative environment. We should have some awsome footage if it actually flies. |

I'd expect to hear some occasional cracking of rocks near sunrise and sunset when temperature is changing rapidly. But maybe InSight is better equipped for this purpose.
Another conceivable application could be a sonar. By measuring signal travel times after a ChemCam shot you could reconstruct some 3d information about the environment; this would of course work better with more than one microphone. But zapping several targets might work, too. And you could learn something about the sound damping properties of the ground, which is related to roughness and hardness. Combine this acoustic surface property map with visual, and maybe with thermal maps, and you get an enriched basis to select targets of interest for contact science. |
