NASA Space Station On-Orbit Status 1 June 2005

"Update on Solid-Fuel Oxygen Generator (SFOG) candles: Two more SFOGs (Russian: TGK) were used today, both successfully. As of tonight, a total of 19 candles of the old set have been decomposed on board since 5/20 (total attempts: 29 [i.e., 10 failures = 34.5% failure rate, instead of expected 20%]). With the actual failure rate, TGKs currently on board last for 25 days. Progress 18 (arrival 6/18) is manifested to deliver 42 "new" SFOGs (zero failure rate) plus 110 kg (242 lbs) of O2."
