NASA ISS On-Orbit Status 4 January 2008

Ergonomics research in space ...

"All ISS systems continue to function nominally, except those noted previously or below.

CDR Whitson & FE-2 Tani started out with the daily reading of SLEEP (Sleep-Wake Actigraphy & Light Exposure during Spaceflight) experiment data accumulated during the night, for logging and filling in questionnaire entries in the SLEEP session file on the HRF-1 laptop for downlink. [To monitor the crewmembers' sleep/wake patterns and light exposure, Dan and Peggy wear a special Actiwatch device which measures the light levels encountered by him as well as his patterns of sleep and activity throughout the Expedition. The log entries are done within 15 minutes of final awakening for seven consecutive days, as part of the crew's discretionary "job jar" task list.]

... The two flight engineers later performed outfitting in the DC1 (Docking Compartment), removing old protective guard cages from SD1-7 lighting fixtures and replacing them with new guards delivered on Progress 27P. The old guards were trashed.

CDR Whitson set up the NUTRITION/Repository hardware for urine and blood collections, to be conducted tomorrow by Dan Tani as part of his Voluntary Weekend Science initiative.

Afterwards, Peggy powered on the ELITE-S2 payload to allow ground verification of proper IMU (Interface Management Unit) function. Later, the CDR turned it off again (IMU can only be powered 2.2 hours per day to avoid violating an acoustic constraint). [The Italian (ASI) experiment ELITE-S2 (Elaboratore Immagini Televisive - Space 2) is a human motion analysis facility for technological characterization and potential application for multifactorial movement analysis, to study the connection between brain, visualization and motion in micro-G. By recording and analyzing the three-dimensional motion of astronauts, this study should help engineers apply ergonomics into future spacecraft designs and determine the effects of weightlessness on breathing mechanisms for long-duration missions.]

... The crew worked out in their regular 2.5-hr. physical exercise program (about half of which is used for setup & post-exercise personal hygiene) on the CEVIS cycle ergometer (CDR, FE-2), TVIS treadmill (FE-1), RED resistive exerciser (CDR, FE-2), and VELO bike with bungee cord load trainer (FE-1).

Afterwards, Dan copied the exercise data file to the MEC laptop for downlink, including the daily wristband HRM (Heart Rate Monitor) data of the workouts on RED, followed by their erasure on the HRM storage medium (done six times a week)."    (Continued via SpaceRef)    [Ergonomics Resources]
