Elektron Just Does Not Want to Be Fixed

NASA Space Station On-Orbit Status 5 May 2005

“After today s major Elektron repair work, the O2 generator continues to be off. Presently (~1:00pm EDT) the O2 partial pressure (ppO2) is 157.6 mmHg. Total cabin air pressure is 753 mmHg. [As per plan, the crew worked for several hours this morning, performing major R&R (removal & replacement) on the electrolyzer by disconnecting the machine s Liquid Unit #5 (BZh-5) and installing instead the previously used BZh-6 (which had been checked out functionally on 4/6 & 4/8 by FE Sharipov and was found acceptable as a good spare).”
