NASA ISS On-Orbit Status 6 July 2008

STATUS REPORT Date Released: Sunday, July 6, 2008 Source: NASA HQ - Comments

All ISS systems continue to function nominally, except those noted previously or below. Sunday -- off-duty for CDR Volkov, FE-1 Kononenko & FE-2 Chamitoff. Ahead: Week 12 of Increment 17.

Crew Sleep Cycle: Wake/sleep cycle remains right-shifted by 3.5 hrs (5:30am - 9:00pm EDT).

Gregory Chamitoff started out on the second part of his Flight Day 30 session with the NASA/JSC experiment NUTRITION w/Repository. This is an all-day session, the second for Greg, of collecting urine samples several times for 24 hrs through first void tomorrow morning. [The NUTRITION project is the most comprehensive in-flight study done by NASA to date of human physiologic changes during long-duration space flight. It includes measures of bone metabolism, oxidative damage, nutritional assessments, and hormonal changes, expanding the previous Clinical Nutritional Assessment profile (MR016L) testing in three ways: Addition of in-flight blood & urine collection (made possible by supercold MELFI dewars), normative markers of nutritional assessment, and a return session plus 30- day (R+30) session to allow evaluation of post-flight nutrition and implications for rehabilitation.]

Oleg Kononenko completed the routine daily servicing of the SOZh system (Environment Control & Life Support System, ECLSS) in the Service Module (SM), including the weekly collection of the toilet flush (SP) counter and water supply (SVO) readings for calldown to TsUP-Moscow. [Regular daily SOZh maintenance consists, among else, of checking the ASU toilet facilities, replacement of the KTO & KBO solid waste containers and replacement of EDV-SV waste water and EDV-U urine containers.]
