NASA Space Station On-Orbit Status 5 October 2004
SpaceRef note: This NASA Headquarters internal status report, as presented here, contains additional, original material produced by SpaceRef.com (copyright © 2004) to enhance access to related status reports and NASA activities.
All ISS systems continue to function nominally, except those noted previously or below.
CDR Gennady Padalka conducted a second experiment session with the Russian/German Plasma Crystal-3 (PK-3) payload, activating the evacuation turbopump, tagging up with ground specialists and starting the evacuation of the vacuum chamber (ZB) and subsequent all-day PK-3 operations. [The experiment is performed on dusty plasma, i.e., fine particles charged and excited by RF/radio frequency power inside the evacuated work chamber as it crystallizes. Experiment ops are automated.]
After the ground had activated the ER2 HRF (Human Research Facility) earlier in the morning, Mike Fincke powered up its laptop and set up the ADUM equipment, after which the crewmembers performed another ultrasound bone scans (Scan Z) on each other, taking turns as operator and subject. Afterwards the hardware was deactivated. The scan heads were cleaned and stowed as part of closeout operations. [The bone scans were taken of the subjects shoulder, elbow, knee and ankle, medically supported from the ground (POIC, Payload Operations & Integration Center) via privatized video and VOX S/G. The data were also recorded, and the scanning and post-scan activities were videotaped and still-photographed. Video and ADUM image files were downlinked post-scan.]

Previous Reports ISS On-orbit Status [HQ] |
In preparation for their return on Soyuz 8S (10/23), the two crewmembers conducted the standard fit check of the Kazbeks, the contoured shock absorbing seats in the Soyuz descent capsule (SA). This required them to don their Sokol pressure suits, get in their seats and use a ruler to measure the gap between the top of the head and the top edge of the structure facing the head. The results were reported to TsUP. [Kazbek-U couches are designed to withstand g-loads during launch and orbital insertion as well as during reentry and brake-rocket-assisted landing. Each seat has two positions: cocked (armed) and noncocked. In the cocked position, they are raised to allow the shock absorbers to function during touchdown. The fit check assures that the crew, whose bodies gain in length during longer-term stay in zero-G, will still be adequately protected by the seat liners for their touchdown in Kazakhstan. The third passenger, Soyuz 9S Flight Engineer Yuri Shargin, will bring his own form-fitted seat liner.]
Gennady conducted the daily routine maintenance of the SM’s SOZh life support system (including ASU toilet facilities) and, from the discretionary task list, prepared the regular IMS (inventory management system) delta file for automated export to the ground for database updating and subsequent re-import via OCA.
Both crewmembers continued preparations of 8S/Soyuz-214 for return, scheduled for Saturday, 10/23 (Eastern time).
Mike Fincke had 15 min blocked out to search and locate an approximately 3 feet long US/RSA-B hose of the WR
M (Water Recovery Management), required for water transfers, behind SM panel 230.
Also behind panel 230, the FE performed an inventory/audit of the contents of the onboard CCPK (crew contamination protection kit) in support of Progress 17P manifesting in the ground.
As done previously by Budarin on TMA-1/5S, Malenchenko on TMA-2/6S, and Kaleri on TMA-3/7S, Gennady removed the two “Klest” (KL-152) TV cameras and their light units from the descent module of the Soyuz 7S. [The cameras are not required for the return of the Expedition 9 crew, and their removal increases 8S downmass capability.]
The crew performed their regular daily physical exercise on the TVIS treadmill and RED resistive exerciser, and Mike Fincke conducted the prescribed weekly maintenance check of the treadmill and its SPDs (subject positioning devices) as well as its time & date settings.
At 11:15am EDT, the crew conducted a live educational PAO exchange with students and guests at the Maryland Science Center in Baltimore, MD. The event was aired on NASA TV.
Working from his discretionary task list, the CDR conducted another run of the Uragan earth-imaging program, using the Kodak 760 DSC (digital still camera) with 800mm-lens. [Today’s task featured imagery of the Southern coast of the Crimean from Sevastopol to the Kerch Strait, the cities of Volgograd and Orsk, the Strait and city of Gibraltar, the city of Budapest, the Carpathian Mountains, and the cities of Kiev and Voronezh.]
At ~8:30am, the ground transitioned the C&C-2 MDM (command & control computer #2) from backup to Primary mode. As part of the ongoing battery reconditioning on BCDU-2 (battery charge/discharge unit 2) of channel 4B, MCC-H also redistributed power loads to the 2B channel (see 9/22 Status report for more details).
