Space Station Status Report for August 29

All ISS systems continue to function nominally, except those noted previously or below.    Sunday – crew rest day. Ahead: Week 13 of Increment 24.

This morning at 8:09am EDT, the ISS (specifically its FGB "Zarya" module) completed 67,500 orbits of the Earth, having covered a distance of 2.91 billion km (1.82 billion st.miles) in 4300 days, or about 5 times the Hohmann travel distance to Mars. [The 19,300-kg/42,600-lbs Zarya ("Dawn") was launched on a Russian/Khrunichev Proton from Baikonur almost 12 years ago, on 11/20/1998, as the first element of the multi-national space station.]

Upon wake-up, FE-6 Walker completed another session with the Reaction Self Test (Psychomotor Vigilance Self Test on the ISS) protocol.   [The RST is performed twice daily (after wakeup & before bedtime) for 3 days prior to the sleep shift, the day(s) of the sleep shift and 5 days following a sleep shift. The experiment consists of a 5-minute reaction time task that allows crewmembers to monitor the daily effects of fatigue on performance while on ISS. The experiment provides objective 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 extended work shifts.]

Shannon concluded her 3rd (FD75) ICV (Integrated Cardiovascular) Ambulatory Monitoring session, doffing the two Actiwatches and HM2 (Holter Monitor 2) about 24 hrs after the end of yesterday's "midpoint" activity (~2:10pm EDT). …
