Complete Fourth STS-110 EVA
All four of STS-110ís spacewalks are in the books with the completion of
the final extravehicular activity at 4:06 p.m. CDT [5:06PM EDT/2106 GMT]
Tuesday. Mission Specialists Jerry Ross and Lee Morin spent 6 hours, 37
minutes outside the International Space Station preparing it for future spacewalks
and working on the Mobile Transporter atop the S0 (S-Zero) Truss.
Preparations included the installation of work lights and the
Airlock Spur -- a 4.3-meter (14-foot) beam that will help spacewalkers
move more efficiently between the Quest Airlock and the S0.
This spacewalk tightens Rossí hold on two U.S. spacewalking
records: the most spacewalks with nine and the most spacewalking time at
58 hours, 18 minutes. His crewmate, Mission Specialist Steve Smith, is
second on both lists with 49 hours, 48 minutes during seven spacewalks.

Space Walk Complete; Shuttle Boosts Station
Astronauts Steve Smith and Rex Walheim wrapped up STS-110ís third
spacewalk at 3:15 p.m. CDT [4:15PM EDT/2015 GMT] Sunday. They continued the
outfitting of the International Space Stationís S0 (S-Zero) Truss during
the extravehicular activity, or EVA.
Smith and Walheim, who also conducted the missionís first EVA, began the
EVA by removing the claw that was used to temporarily hold the S0 onto the
Destiny Laboratory and rerouted power, data and video connections through
the S0 for later operation of the stationís robot arm - Canadarm2.
They also devoted time to preparing the Mobile Transporter for
its first test run on Monday by removing launch restraints and a thermal cover.
The Mobile Transporter is a railcar that is located on a rail on the S0.
After the EVA, Pilot Steve Frick spent an hour firing Space
Shuttle Atlantis' steering engines to boost the space station's orbit by
about 3.2 kilometers (2 miles). This was the second of three planned
orbital adjustments for the International Space Station.

in the middle of STS-110's third spacewalk.
Spacewalkers Outfitting S0
hours into today's third spacewalk of the STS-110 mission, flight
controllers told Atlantis spacewalkers Steve Smith and Rex Walheim that
their rewiring of the primary set of avionics on the International Space
Station's Canadarm2 was successful. The reconfiguration enables the arm to
receive power from the new S0 Truss rather than the Destiny Laboratory
upon which the truss is bolted in place.
Smith and Walheim reconfigured electrical connectors on the
prime string of the arm's power systems before pressing ahead to release
locking devices holding the 1900-pound Mobile Transporter railcar in place
on the newly installed S0 Truss. The new railcar's systems will be tested
overnight before it is commanded to move about 32 feet up and down the S0
Truss rail Monday at a speed of about eight-tenths of an inch per second.
With the spacewalk proceeding on the timeline, Smith and Walheim
will reconfigure electrical connections on the backup, or redundant string
of avionics on the station's robotic arm and will release locking bolts on
a 14-foot ladder called the Airlock Spur which will be pivoted to the
Quest Airlock and bolted down to provide an easy path for future
spacewalkers moving from Quest to the truss itself.
After this EVA is over, Monday will be spent testing the Mobile
Transporter, the first
"railway in space". The fourth and final spacewalk will be
tackled on Tuesday by grandfathers

CDT 9:48AM EDT/1348 GMT] today. Their objective is to continue the
outfitting of the S0 (S-Zero) Truss.
Their first scheduled tasks are to release a claw that
temporarily secured S0 and to reroute power, data and video through the
truss for later operation of the space station robotic arm, Canadarm2. The
truss was permanently secured during STS-110's first two spacewalks.
The two spacewalkers are also slated to prepare the Mobile
Transporter for use by releasing launch restraints and removing a thermal
cover. Another task during the spacewalk is the installation of a beam
that will help future spacewalkers.
