If there were e.g. a propellant depot on Deimos, a returning Starship could have enough extra delta-v to bleed off quite a bit of speed... -

Didn't Elon also say that it the liquid could (somewhat counter-intuitively) get "shock frozen" in the pores when the ship slams in to...

It would be interesting if they could develop something with the consistency of epoxy they could apply directly to a honey-comb like...

Do you mean like kitchen tile sheets being secured to a wall with grout? I'm trying to understand the combination of epoxy, honeycomb...

I was thinking of the heatshield itself to be applied in an epoxy-like fashion, in essence taking @Ben W 's idea of attaching the edges...

What material like that won't ablate? If it's a ceramic paste, then it needs to be fired - which is why they have discrete tiles. It...

Yeah... I'm not a materials science expert by any means. Just that if there were a way to combine the advantages of a single "surface"...

That takes me back to the tile sheet approach. Create a sheet of a bunch of small tiles that are meshed together with wires or...

Relative speed of spacecraft and atmosphere. The atmosphere spins along with the planet, so technically that should be taken into...

Does this imply that Starship’s reusable tile approach won’t work for Mars and Mars return? Could they simply make the tiles thicker to...

Seems with the standard expansion/contraction known with metals along with the hostile use case adhesive will always be the weak point.

Agreed, which is why connecting the tiles to the ship via physical interlocking may be a more robust solution than adhesive. If the...

Here's a page on stackexchange about reentry speed from Mars. It observes that SpaceX believes that arrival at Mars would be at 7.5...

Probably in some cases. Just a 1% risk is way too much. 1% likelihood of a tile falling off multiplied by 1% likelihood it ends in the...
