With NASA’s space shuttle program in full wind-down, it seems like there are a lot of “lasts” in America’s storied, three-decade Space Transportation System. Space shuttle Discovery successfully touched down at Kennedy Space Center in Florida just before noon today, marking the end of STS-133 and Discovery’s final mission, the 39th and last flight for the busiest spacecraft in NASA’s shuttle fleet.
After a two-day delay and a good deal of much-deserved sentiment, the Space Shuttle Discovery – NASA’s oldest active shuttle – is at the launch pad and go for launch for its final mission, with liftoff slated for 3:52 p.m. EST tomorrow. Technicians are spending the day making the final inspections of the external liquid oxygen feedlines, and onboard ground communications will be activated this afternoon. It will be Discovery’s 39th flight in 26 years.
