The point I guess was, that it does not really matter, since speed is
relative. The spaceship just needs to adapt its own speed to that planet
it intends to land on. Is not different than the good Russian rockets and
spaceships adapting their own speed to the International Space Station
(which between us, is a de-facto Russian Space Station (RSS)). Same
procedure. You leave Earth and adapt your speed correspondingly.
