This is for a fiction project I'm working on. Assuming it becomes possible to someday land on Pluto, what hazards might be encountered given what we've learned about its surface makeup?
The primary difficulties I can think of are the sparse atmosphere and the temperature. Pluto's atmosphere is incredibly thin, to the point that it is functionally useless for aerobraking or parachutes on descent. This means that any lander would have to burn a lot of fuel on descent.
Since Pluto is so cold, power supply is also an issue. Battery life would be short due to the temperature, so another form of power (like an RTG) would be required for a mission of any serious length.
