The STS-116 crew’s stay at the International Space Station is winding
down. Space Shuttle Discovery and its crew are slated to leave Tuesday
to conclude an eight-day stay in which STS-118 added a new truss segment
to the station, delivered a new crew member and rewired the orbital
outpost’s power system.
Discovery is scheduled to undock from the station at 5:09 p.m. EST Tuesday.
The STS-116 crew conducted three spacewalks to install the P5 integrated
truss segment and rewire the station’s power system. The P5 spacer
segment’s attachment to the P4 sets the stage for the relocation of the
P6 and its set of solar arrays. The rewiring activities put the
station’s power system in a permanent setup. A fourth spacewalk was
conducted to assist in the retraction of the troublesome port solar
array on the P6.
The P5’s installation is not the only change that the station has
undergone since Space Shuttle Discovery docked last week. Sunita
Williams, who arrived at the station with the STS-116 mission, replaced
European Space Agency Astronaut Thomas Reiter on the Expedition 14 crew
at midnight Tuesday, Dec. 12.
Williams will remain a member of Expedition 14 until Commander Michael
Lopez-Alegria and Flight Engineer Mikhail Tyurin are relieved by
Expedition 15 in March 2007. Williams will finish her remaining time of
her six-month tour of duty on the station as a member of Expedition 15.
Reiter will return to Earth with STS-116.
Also, the STS-116 and Expedition 14 crews have worked together to
transfer Discovery 4,292 pounds of supplies and equipment delivered to
the station by Discovery. The two crews have also transferred 3,725
pounds of cargo that will return to Earth with STS-116.
