Aerodynamic drag is amazing. It means fins and parachutes work. It means you can slow yourself down without propellant and with passive systems.
Mars actually kind of sucks too because it has just enough atmosphere to interfere with rocket engine ignition but not enough to be able to land on chutes alone. But any amount of parachute and aerobraking is better then none.
But the Moon is terrible: no atmosphere, so you're under engine power the whole way down. The propellant and mass demands are thus much higher.
- jdminhbg 3y agoThanks, good explanation. My thought on "no atmosphere" is that it eliminates the need for heat shielding to enter it, but I can see how that's not really an issue compared to all the benefits.
