Okay, we now have definitive pictures of VL1, 2, Spirit, Opportunity, and a Pathfinder coming up soon. So, now, what would the lost landers look like, starting with Beagle, MPL, and Mars 6, which will be the easiest to find of the landers. Just curious to hear your thoughts. Thanks!

What was Mars 3's landing system like - and thus what other hardware would we expect to find locally? Heatshield size, was there a backshell. Did the chute stay attached to the lander etc etc.

Did the chute stay attached to the lander etc etc. I recommend you to take a look at that movie. Reentry vehicle views as well as entry, descent and landing timeline are both presented there. There was no backshell attached to parachute system as it was in the american Mars missions. Chute was ejected by retrorockets before the landing. Attached images illustrate reentry vehicle size and final vehicle configuration just before the touchdown. According to these pictures we have to find: heatshield (~4 meters in diameter), toroidal block (~2 m in diameter), retrorockets, landing apparatus itself (an "egg" 1-1.5 meter in size) |

There was no backshell attached to parachute system as it was in the american Mars missions. Chute was ejected by retrorockets before the landing. But there is a confluence point for the riser to the parachute, than contained those smaller solids - so there should be something quite obvious, right next to it. The heatshield could be findable - that's quite large - larger than MER. Thanks for the movie link - for all kinds of retro reasons - it's amazing! |
