NASA tests supersonic parachute, to help us land on Mars

Depends on the heat load.

IIRC normal parachute nylon is about 70g/m^2 but high temperature materials are more around 700g/m^2 (the HIAD demonstrator was "loosely" a parachute type material).

But Mars Sea Level is 1/160 that of Earth Sea Level, so what would be a baking temperature for an Earth entry could be quite survivable with just Nylon, even though you're slamming into it at very high speed.
