Love delivered the gyroscope while riding on the Canada Arm II.
Walheim and Love
Spacewalkers catching up
Making up a nearly half hour deficit from the spacewalk timeline, Rex Walheim and Stan Love began attaching the control moment gyroscope in Atlantis' payload bay.
Love carried the CMG on the Canada Arm II from a storage platform on a truss to the bay.
The 1,200-pound gyroscope failed in October 2006 and was replaced. It will be returned to Earth, refurbished and saved for a spare. Four working gyroscopes keep the space station in the correct orientation.
Love's glove was slightly damaged, but he was given permission to continue working.
The spacewalk officially began when the pair switched their spacesuits to battery power at 8:07 a.m. EST. Walheim's helmet camera will be No. 18, while his spacesuit will have an unbroken line. Love's camera will be No. 16, while his spacesuit has a broken line.
On the mission's third spacewalk, Love will function like a human forklift, holding three massive - but weightless - pieces of equipment while he is attached to the space station robot arm. On separate swings of the arm, he will move two European experiment modules and a gyroscope.
If the 6.5-hour spacewalk runs ahead of schedule, Walheim and Love will have several additional tasks: inspecting the starboard solar alpha rotary joint and inspecting damage to a handrail that might be causing glove damage.
Atlantis is scheduled to land at 9:06 a.m. Wednesday at Kennedy Space Center, shortly before the Navy shoots down a low-orbiting, non-functioning spy satellite that carries a toxic half-ton of hydrazine rocket fuel.
