Re: Mars InSight lander

I note the indent in the surface made by InSight's foot pad.
How much bigger will be the dent beneath the foot of a fuelled up BFR? Spacex must come up with a solution to this issue.

Re: Mars InSight lander

SpaceNut,

If a rather light lander like InSight makes that much of an impression in the surface, then Starship will require serious rough field landing capability or it will tip over when the ground shifts as it lands.  I think explosively driven anchors will be required to assure that the vehicle is secure when it touches down.  Anchors would also provide a more secure launch when the vehicle departs.  Some minor hardware replacement will be required, but that's still infinitely preferable to tipping over in loose regolith.

Re: Mars InSight lander

Something else to make note of is with the solar panels that after dust was accumilating just happened to get cleaned off once more from the ability it has to move....
