After the return to Earth that took place yesterday the Space Shuttle Discovery has been retired. At the end of this mission the Space Shuttle Discovery has flown nearly 150 million miles during 39 flights for a total of 5,247 orbits in 322 days divided over 27 years of distinguished service and in this case it’s not just rhetoric. With these numbers the Discovery is the spaceship that was used the most.
