Russian Oxygen Generation and CO2 Removal Systems Offline

NASA Space Station On-Orbit Status 6 April 2005

“The Elektron O2 generator remains off. The FE today performed part 1 of a functional checkout on an older spare liquid unit (BZh #6), supported by tagup with ground specialists. Both micropumps were diagnosed “with bubbles”. More troubleshooting is planned for Friday (4/8).” …”With the Vozdukh carbon dioxide (CO2) removal system turned off, Salizhan replaced the second LiOH (lithium hydroxide) absorbent filter cartridges (PP) and activated it. This is the second of 14 lifetime-expired but unused Russian LiOH canisters onboard.”
