NASA Space Station On-Orbit Status 4 July 2004

SpaceRef note: This NASA Headquarters internal status report, as presented here, contains additional, original material produced by (copyright © 2004) to enhance access to related status reports and NASA activities.

All ISS systems continue to function nominally except those noted previously.   Happy Independence Day to All!

Sunday — second day of a three-day holiday for the crew (and folks down here).  Ahead: Week 10 for Increment 9.

CDR Padalka completed the regular daily maintenance/inspection of the Service Module (SM)’s environment control & life support systems (SOZh), including routine toilet system (ASU) replacements.

Also part of Gennady’s SOZh job today was the weekly data collection of the SM’s toilet flush counter readings, with inspection of the urine collection (SP) & pretreat assembly and water supply status (SVO) counter readings, both for calldown to TsUP/Moscow.

In the DC1, Padalka terminated the discharge procedure started yesterday on the first 825M3 Orlan backpack battery, then initiated the process, necessary for preserving battery lifetime, on the second unit.

FE/SO Mike Fincke had his weekly PFC (private family conference) via S-band/audio.

Both crewmembers completed their regular daily physical workout of 2.5 hrs on their exercise equipment (TVIS treadmill, RED pulley machine, and VELO ergometer with force loader).

As mentioned yesterday, new replacement pages have been uplinked to Fincke for printing and incorporation in the Emergency Books as a task item.  They involve steps correcting an error in the way a leak in the Airlock’s Equipment Lock (A/L E/L) should be handled.   [The error was found during a recent crew training session.]

Today’s optional CEO photo targets, in the current LVLH attitude no longer limited by flight rule constraints on the use of the Lab nadir/science window, except for the shutter closure and condensation-prevention plan (limited to 90 min. in 24 hours), were Sao Paulo, Brazil (nadir pass over one of the largest cities on the planet–20-24 million people probably live in this urban region.  More than one image will be needed to capture the margins of the built-up area), Salton Sea, California (salinities and water levels often rise to dangerous levels, threatening aquatic populations and coastal buildings and structures.  The mechanism of salinity control generally recommended is the construction of a diked impoundment within the waterbody.  Water would flow into the impoundment and evaporate.  The main [and smaller] body of the sea would continue to receive the relatively fresh inflow water, thereby reducing salinity), and Internal waves, Central America (looking left towards the glint point and Pacific coast of Central America for packets of waves.  This is one of a few zones on the planet where the cause of internal waves is enigmatic).

CEO images can be viewed at the websites.
