"The crew burned one SFOG (solid-fuel oxygen generator) "candle" today to increase ppO2 (oxygen partial pressure). An attempt to burn a second candle, however, was unsuccessful. [Russian ECLS specialists have estimated that approximately 20% of the onboard SFOGs will not ignite, which is taken into account in the onboard O2 supplies estimates."
