how fast does a human spaceship go
RE: How fast can a space shuttle travel? How fast are we capable of making a space shuttle travel? I&#39;m asking because I was reading about the new planet, Gliese 581, which is said to have earth like habitation characteristics, but is 20.5 lightyears away-- impossible to reach in a human lifetime.So I would like to know how fast our...Source(s): fast space shuttle travel: https://shortly.im/rrd61.eport Abuse. Well, the space shuttle normally cruises along at 17,000 mph. At that speed, assuming a straight line shot to Gliese 581, it would take 810,502 years to get there. If we go back to the velocity of the Apollo missions to the moon (..about 45,000 mph..) we're down to a one-way trip of 305,706 years.
