ISS crew works on new oxygen generator
The three radio hams who comprise the Expedition 14 crew spent a busy
week aboard the International Space Station working to install a new oxygen-generating
system, adding soundproofing in the living quarters and unpacking supplies
delivered by the space shuttle in December.
Commander Mike Lopez-Alegria, KE5GTK and Flight Engineer Suni Williams,
KD5PLB, primarily focused this week on the first phase of installing a
new oxygen-generating system. This additional system will be needed as
a supplement to the Russian Elektron oxygen generator when the permanent
crew aboard the station expands from three to six people. The new system
will be activated and tested later this year.
Meanwhile, Flight Engineer Mikhail Tyurin, RZ3FT, spent several days
this week modifying the ventilation system in the service module to run
more quietly. He added two new noise-isolation crew cabin fans, sound
deadening vibration isolators and air ducts with acoustic shields.
On Friday, Lopez-Alegria and Williams took time out from their tasks
to speak with students at the Columbia Explorers Academy. The students
asked the astronauts about living in orbit and the goals of their mission.
