  Many rocky exoplanets are heavier and larger than Earth, so-called
"Super-Earths". Some of these may be habitable, and a few may be inhabited by
Super-Earthlings. Due to the higher surface gravity on these worlds,
space-flight is much more challenging. We find that chemical rockets still
allow for escape velocities on Super-Earths up to 10x Earth mass. Much heavier
rocky worlds, if they exist, will require using up most of the planet as
chemical fuel for the (one) launch, a rather risky undertaking. We also briefly
discuss launching rockets from water worlds, which requires Alien
megastructures.
