Space Station Status Report for July 11

All ISS systems continue to function nominally, except those noted previously or below. Sunday – crew rest day. Ahead: Week 6 of Increment 24

At wake-up, CDR Skvortsov performed the regular daily early-morning check of the aerosol filters at the Russian Elektron O2 generator which Maxim Suraev had installed on 10/19/09 in gaps between the BZh Liquid Unit and the oxygen outlet pipe (filter FA-K) plus hydrogen outlet pipe (filter FA-V). [The CDR will inspect the filters again before bedtime, currently a daily requirement per plan, with photographs to be taken if the filter packing is discolored.]

FE-2 Caldwell-Dyson, FE-4 Doug Wheelock & FE-6 Shannon Walker continued their current week-long session of the post-wakeup experiment SLEEP (Sleep-Wake Actigraphy & Light Exposure during Spaceflight), Tracy's 5th, 1st for Wheels & Shannon, transferring data from their Actiwatches to the HRF-1 (Human Research Facility 1) laptop. [To monitor his/her sleep/wake patterns and light exposure, the crewmember wears a special Actiwatch device which measures the light levels encountered by him/her as well as their patterns of sleep and activity throughout the Expedition, using the payload software for data logging and filling in questionnaire entries in the experiment's laptop session file on the HRF-1 laptop. The log entries are done within 15 minutes of final awakening for seven consecutive days.]

Wheelock & Walker continued their Pro K session with the urine pH spot test after wake-up.…
