International Space Station crew re-activates Elektron system
The three radio amateurs, who make-up the Expedition 14 crew, spent time
last week unpacking items, including parts for the Elektron oxygen-generation
system, fresh food and other system hardware from the Progress cargo ship.
The remaining items will be unpacked as needed or when time permits.
The Elektron oxygen-generation unit, which had been shut down since mid-September,
has been re-activated.
Early last week, Flight Engineer Mikhail Tyurin, RZ3FT, repaired the
unit by installing new valves and cables that arrived on the recent Progress
cargo craft. The Elektron is supplying oxygen for the cabin atmosphere
once again.
Commander Mike Lopez-Alegria, KE5GTK, worked on robotics proficiency
tasks throughout the week. His robotics exercises included maneuvering
the Canadarm 2 robotic arm over to the Mobile Transporter and its operating
base. He also practiced modified grapple and release procedures.
The commander also performed the scheduled lens change on the EarthKAM,
going from 50mm to the 180mm-lens configuration. The camera takes pictures
by remote operation from the ground by students who submit image requests
to conduct geographic research.
