NASA ISS On-Orbit Status 13 May 2008

STATUS REPORT Date Released: Tuesday, May 13, 2008 Source: NASA HQ - Comments

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

From the US voluntary "job jar" task list, after wakeup and before breakfast, FE-2 Reisman downloaded the SLEEP (Sleep-Wake Actigraphy & Light Exposure during Spaceflight) experiment data from his Actiwatch to the HRF-1 (Human Research Facility 1) laptop. [To monitor his sleep/wake patterns and light exposure, Garrett wears a special Actiwatch device which measures the light levels encountered by him as well as his patterns of sleep and activity throughout this week, for the last time. The log entries are done within 15 minutes of final awakening for seven consecutive days.]

CDR Volkov completed the periodic servicing of the active Russian BMP (Harmful Impurities Removal System) by starting the "bake-out" cycle to vacuum on absorbent bed #1 of the regenerable dual-channel filtration system. The regen process will be terminated before sleeptime, at ~5:15pm EDT. Regeneration of bed #2 follows tomorrow. [Regeneration of each of the two cartridges takes about 12 hours and is conducted only during crew awake periods. In order to assist in atmosphere scrubbing after the Freon- 218 (Khladon) spill from the SKV-2 air conditioner on 4/24, the BMP's regeneration cycle was moded to 5 days instead of the regular 20 days.]
