NASA Space Station On-Orbit Status 15 May 2005

SpaceRef note: This NASA Headquarters internal status report, as presented here, contains additional, original material produced by (copyright © 2005) to enhance access to related status reports and NASA activities.

All ISS systems continue to function nominally, except those noted previously or below. Sunday — second crew rest day. Ahead: Week 4 for Increment 11.

Krikalev and Phillips were scheduled to perform another repress of the cabin atmosphere with oxygen from Progress 17P storage (planned ppO2 increase: 10 mmHg).

The FE/SO started the 24-hr. charging process on the “Pilobolus” voltage/current scopemeter’s NiCad battery, to support tomorrow’s continuation of UOP-4 (utility outlet panel 4) component troubleshooting, after its trip of RPC-4 (Remote Power Controller #4) last November. [Recalling: Past work by Leroy Chiao on UOP4-associated hardware has exonerated a number of these loads as causes of the RPC trip.]

The CDR conducted the daily routine maintenance/inspection of the Service Module’s SOZh environment control & life support system, including the ASU toilet facility.

The crew performed their regular daily 2.5-hr. physical exercise program on the CEVIS cycle ergometer, RED resistive exerciser and VELO bike with bungee cord force loader (NS-1). [As reported yesterday, the TVIS treadmill is currently off limits, and a major IFM (in-flight maintenance) is scheduled for tomorrow, to replace all gyroscope wire ropes with new wire ropes, then reinstall the TVIS back in its “pit” in the SM floor. Afterwards, one crewmember is to perform a nominal exercise run in motorized mode to ensure the treadmill is functioning OK. After engineering evaluation of the exercise data, a recommendation as to the success of this activity will then be provided.]

Afterwards, John transferred the exercise data files to the MEC (medical equipment computer) for downlink, as well as the daily wristband HRM (heart rate monitor) data of his workout on RED and CEVIS, followed by their erasure on the HRM storage medium.

Sergei again had three new voluntary work items on his “job jar” task list for today, starting with his first run of the “Diatomeya” ocean observations program, using the DSR PD-150P video camera on ASM window #8 and Nikon F5 digital still camera with 24/85-mm lens from window #7 to obtain data about hydro-biological processes in the dynamic regions of the Atlantic Ocean. [Today’s observations focused on the South Atlantic, then the North Atlantic.]

Also off his task list, Sergei conducted another session with the “Uragan” (hurricane) earth-imaging program, focusing the Nikon D1X No. 3 digital camera with 800-mm lens on targets called out on an uplinked list. [Targets for today were the Himalayas and Pamir mountain ranges, highways and railway from Kurinskaya station in the city of Tuapse, the Stavropol and Kalmjkii Territories, the Volga River and the city of Volgograd.]

A third item suggested by Krikalev’s task list was to repair the currently inoperable Russian Regul-Packet comm system by changing out its failed laptop with a new A31p ThinkPad machine and setting it up with the appropriate Regul-Packet traffic software.

No CEO (Crew Earth Observation) targets today.
