STS-135 MCC Status Report No. 27
Thursday, July 21, 2011, 9:30 a.m. CDT

Atlantis landed at 4:57 a.m. CDT Thursday, wrapping up a successful 13-day
mission, ending its own 33-flight career and closing out the 30-year,
135-flight Space Shuttle Program.

Kennedy Space Center weather was near perfect with light winds and clear
skies. Atlantis glided to a smooth predawn landing under a waning half-moon.

"Mission complete, Houston," said Commander Chris Ferguson just after wheels
stop. "After serving the world for over 30 years, the shuttle has earned its
place in history, and it has come to a final stop."

Entry Capcom Barry Wilmore responded: "We congratulate you, Atlantis, as
well as the thousands of passionate individuals across this great
spacefaring nation who truly empowered this incredible spacecraft which
has inspired millions around the globe."

Atlantis crew members, Ferguson, Pilot Doug Hurley and Mission Specialists
Sandra Magnus and Rex Walheim, wound up the successful mission to the
International Space Station. It left the station with about 9,400 pounds of
equipment and supplies carried aloft in the Raffaello multi-purpose
logistics module, and almost 2,300 pounds of experiments, equipment and
supplies brought up in its middeck lockers.

Atlantis returned almost 5,700 pounds of unneeded equipment and trash in
Raffaello. The shuttle also brought back material, including experiments, in
its middeck lockers and a 1,400-pound pump module. Part of the station
cooling system, it had failed last year. It will be examined to determine
what caused the failure.

During Atlantis' eight-day, 15-hour stay at the orbiting laboratory, station
Flight Engineers Mike Fossum and Ron Garan did a 6.5-hour spacewalk that
included placing the pump module in the shuttle cargo bay and installing on
the station a satellite refueling experiment called the Robotic Refueling
Mission.

On Atlantis' way home the small PicoSat, designed to evaluate performance of
a variety of solar cells, was deployed from the cargo bay.

During STS-135, Atlantis orbited the Earth 200 times, traveling 5,284,862
statute miles. Over its 33 missions, it spent 307 days in space, completing
4,848 orbits and traveling 125,935,769 miles. STS-135 was the 37th visit of
a space shuttle to the station.

Shuttles on all 135 missions traveled more than 542 million miles in space.

This was the 78th shuttle landing at Kennedy Space Center. Shuttles landed
54 times at Edwards Air Force Base in California and once, on Columbia's
STS-3 flight in March 1982, at White Sands Space Harbor in New Mexico.

A celebration of Atlantis crew members' homecoming will be held in Houston
at 4 p.m. Friday. Open to the public, the ceremony will be held at
Ellington's Hangar 990. Ellington gates will open at 3:30 p.m.
