'Red Dragon' Mission Mulled as Cheap Search for Mars Life
any opinion on this? would it really make sense adapting a manned spaceship to unmanned Mars landing? I am skeptical... if replying, please remember forum guideline 1.5 |

I had a wild idea, does anybody know if it is technically feasible?
Instead of extending a drill mechanism out of the main hatch, would it be possible to simply drill straight down right through the heat shield? This drill would, after all, be built to drill through solid rock, and I believe that the material that heat shields are made of is designed for heat resistance/ablation, not rock-like strength, in fact they are quite fragile as I understand it. Or alternatively, perhaps the shield could incorporate a small 'cap' directly below the base of the internal drill mechanism, that can be removed upon landing. (It might be simpler and less problematic to simply drill right through the heat shield, though.) If the drill is not required to be physically extended out the main hatch by some kind of robot arm, the mass and volume saved by not including the required arm mechanism could be used for additional instrumentation, not to mention that it would be a lot easier to extract the drill cores to the interior of the Red Dragon. |

From Emily's Planetary Society blog:
QUOTE Moving on to new ideas, here's VP Kris Zacny showing off a huge drill for Mars subsurface sample acquisition. They have field-tested it in Antarctica (working with Chris McKay), and they have tricky ways of delivering samples from different depths below the surface to waiting science instruments. He also talked about how they've worked with SpaceX to figure out how the "Red Dragon" -- a Mars lander based on SpaceX's Dragon capsule -- might take not one, but two of these beasts down to land on Mars. They'd sit inside the capsule, and drill right through Dragon's heat shield to get to Martian soil, delivering the samples back inside the capsule to instruments. Not to blow my own horn (well, not too loudly) but here is a post I made here seven months ago: I had a wild idea, does anybody know if it is technically feasible?

Good call, Mongo! Now, do you have some suggestions about how they can avoid contaminating the samples?
