Space Station Status Report for June 9

All ISS systems continue to function nominally, except those noted previously or below. Soyuz 27S Docking Day.

The ISS crew has entered a sleep cycle shift to accommodate tonight's Soyuz docking, with a short workday this morning (Period 1) and a long work period later tonight (Period 2):

• Wake: 2:00am – 9:00am

• Sleep: 9:00am – 1:00pm

• Wake: 1:00pm – 3:00am (6/10)

• Sleep: 3:00am (6/10) – 2:00am (6/11).

(returning to Normal on 6/12).

FE-1 Samokutyayev terminated his 3rd experiment session, started last night, for the long-term Russian sleep study MBI-12/Sonokard, taking the recording device from his Sonokard sports shirt pocket and later copying the measurements to the RSE-Med laptop for subsequent downlink to the ground. [Sonokard objectives are stated to (1) study the feasibility of obtaining the maximum of data through computer processing of records obtained overnight, (2) systematically record the crewmember's physiological functions during sleep, (3) study the feasibility of obtaining real-time crew health data. Investigators believe that contactless acquisition of cardiorespiratory data over the night period could serve as a basis for developing efficient criteria for evaluating and predicting adaptive capability of human body in long-duration space flight.]

At wake-up, FE-3 Garan conducted another session with the Reaction Self Test (Psychomotor Vigilance Self Test on the ISS) protocol, his 22nd. …
