Once I land on a planet, I can exit my rocket and walk around freely. However, after putting the "Return ticket to Earth" item in the target slot in the Rocket Station, and clicking Assemble Rocket, my rocket despawns entirely instead of assembling the rocket. It does this on the Moon and on Mars, however I believe the other planets do the same as well.
