NASA ISS On-Orbit position 26 February 2012

All ISS system go on to function supposedly, apart from those noted before or below. Sunday - Crew off duty. Ahead: Week 14 of increase 30 (six-person crew).CDR Burbank, FE-5 Kuipers & FE-6 Pettit each finished one more post-sleep session of the Reaction Self Test (Psychomotor Vigilance Self Test on the ISS) procedure, the 31st Dan, the 25th for Andre & Don. 

[RST is done two times daily (after wakeup & before bedtime) for 3 days previous to the sleep shift, the day(s) of the sleep shift plus 5 days following a sleep shift. The trial consists of a 5-minute response time job that allows crewmembers to monitor the daily effects of fatigue on performance while on ISS. The experiment provides object feedback on neurobehavioral changes in attention, psychomotor speed, state stability, and impulsivity while on ISS missions, particularly as they relate to changes in circadian rhythms, sleep restrictions, and comprehensive work shifts.]
