Astronauts Rex Walheim and Stanley Love completed the third and
last STS-122 spacewalk at 1532 EST Friday.
During the seven hour, 25-minute excursion, Walheim and Love
installed two payloads on the exterior of the European Space
Agency’s Columbus laboratory. The first, SOLAR, is an
observatory that will monitor the sun for two years. The second is
the European Technology Exposure Facility, which will carry nine
experiments requiring exposure to the space environment.
With Mission Specialist Leland Melvin driving the space
station's robotic arm, Love carried each of the experiment packages
from space shuttle Atlantis’ payload bay to Columbus where
the spacewalkers installed them.
In addition, Walheim and Love -- with the help of the
station’s robot arm -- moved a failed control moment
gyroscope from its storage location on the station to the
shuttle’s payload bay for return to Earth. The spacewalkers
examined a small divot on a handrail near the Quest airlock to
collect data on whether it could be a possible source for glove
damage on recent spacewalks. They also installed handrails on
Pilot Alan Poindexter guided the spacewalkers from inside the
Atlantis and the STS-122 crew are scheduled to leave the space
station on Monday, with undocking slated for 0426 EST that day. The
orbiter is scheduled to land back at Kennedy Space Center at 0906
EST Wednesday, February 20.
