Space Shuttle Endeavour Set to Land at Kennedy at 2:35 a.m. EST Wednesday

Space shuttle Endeavour Commander Mark Kelly, pilot Greg Johnson and mission specialists Mike Fincke, Andrew Feustel, Greg Chamitoff and Roberto Vittori are on the last leg of their 16-day mission. The astronauts are scheduled to land at NASA's Kennedy Space Center in Florida at 2:35 a.m. EST Wednesday, June 1.

Endeavour launched on its final flight to the International Space Station May 16. It delivered a $2 billion astrophysics experiment and extra supplies to the station to help position the orbiting outpost for the years following the end of the shuttle program. Endeavour's crew conducted four spacewalks to upgrade the massive complex in space.

If Endeavour lands Wednesday as scheduled, it will have spent 299 days in space and traveled more than 122.8 million miles during its 25 flights.

After this flight, NASA will launch only one more space shuttle mission. The shuttle Atlantis will lift off July 8 and then, just like that, the 30-year space shuttle program will glide to rest in the history books.
