The ultimate in RC!

They would not pop. You would need MUCH less gas to fill them, but they wouldn't pop. Space suits don't pop. The only thing that needs to be air-tight is the pressure system, not the entire rover. Yeah everything that is pressurized would need to be reinforced, oh IDK, 10 times as much as here on Earth, but it is feasible and likely would have saved the current mission. I still think it should have a harpoon winch, too.
