Attired in training versions of their shuttle launch and entry suits, these four astronauts take a break from training to pose for the STS-135 crew portrait. Pictured are NASA astronauts Chris Ferguson (center right), commander; Doug Hurley (center left), pilot; Rex Walheim and Sandra Magnus, both mission specialists. 

"It is great to have Atlantis safely home after a tremendously successful mission -- and home to stay," said Bob Cabana, Kennedy Space Center director, referencing Atlantis' retirement at Kennedy's Visitor Complex.

"I'm unbelievably proud to be here representing the Space Shuttle Program and the thousands of people across the country who do the work," said Mike Moses, space shuttle launch integration manager. "Hearing the sonic booms as Atlantis came home for the last time really drove it home to me that this has been a heck of a program."

"The workers out here and across the country in the Space Shuttle Program have dedicated their lives, their hearts and their souls to this program, and I couldn't be more proud of them," said Mike Leinbach, space shuttle launch director at Kennedy.

A crew news conference with the STS-135 astronauts is scheduled for noon and will be carried live on NASA TV and online at www.nasa.gov/ntv.

Atlantis landed at 5:57 a.m. EDT, after 200 orbits around Earth and a journey of 5,284,862 miles.

The STS-135 crew consisted of Commander Chris Ferguson, Pilot Doug Hurley, Mission Specialists Sandra Magnus and


Rex Walheim. They delivered more than 9,400 pounds of spare parts, spare equipment and other supplies in the 

Raffaello multi-purpose logistics module - including 2,677 pounds of food - that will sustain space station operations for the next year. The 21-foot long, 15-foot diameter Raffaello brought back nearly 5,700 pounds of unneeded materials from the station.
