NASA Space Station On-Orbit Status 11 Jun 2004 — iss

All ISS systems continue to function nominally except those noted previously or below. Yesterday, on the occasion of today’s burial ceremonies in Washington, DC, the ISS crew downlinked a tribute to President Ronald Reagan. Fincke said, in part: “President Reagan proposed building the Space Station, which Gennady and I are privileged to be working aboard today for the benefit of all humankind. He spoke to astronauts in space during his tenure in the White House, greeted the crew of Columbia at Edwards Air Force Base after its fourth voyage and mourned the loss of the Challenger crew along with the rest of us.” He and Gennady then honored the 40th U.S. President (who had started the ISS Program with “Freedom”) with 40 chimes of the ISS ship’s bell.”on behalf of all of NASA.”

After the cancellation/deferment of today’s Orlan suit dry run, the crew executed a revised task schedule, beginning with CDR Padalka working on the Service Module (SM)’s water supply system to pressurize the collapsed bladders of the Rodnik water storage tanks (BV1 & BV2) in the 14P/Progress-249 vehicle, a 3-hr task, as a leak-checkup preparatory to the regular transfer of liquid waste (urine) from EDV-U containers to the Progress for disposal. [Each of the two spherical Rodnik tanks consists of a hard shell with a soft membrane (bladder) composed of elastic fluoroplastic, which is used to expel water from the tank by compressed air pumped into the tank volume surrounding the bladder.]

FE/SO Mike Fincke disconnected the UOP DCP (utility outlet panel/display & control panel) bypass power cable at the Lab RWS (robotics work station).

Mike then spent 1.5 hrs in the FGB, continuing the current round of ventilation systems maintenance in the Russian segment (RS) by cleaning the vent screens of specific interior closeout panels (116, 231, 316 & 431).

Afterwards, the FE logged in and performed his second session with the psychological MedOps WinSCAT (Spaceflight Cognitive Assessment Tool) experiment, using an uplinked “crib sheet” instead of PC-supplied data due a software problem that programmers are still working on. [WinSCAT is a time-constrained questionnaire test of cognitive abilities, routinely performed by astronauts aboard the ISS every 30 days before or after the PHS (periodic health status) test or on special CDR’s, crewmember’s or flight surgeon’s request.]

After performing filter cleaning on the SAMS (space accelerations measurement system), Fincke continued troubleshooting the SAMS ICU (interface control unit) computer with battery checks. [Purpose of the troubleshooting was to help determine whether the problem is in the battery or in the power management system of the laptop. The ground is working on a software patch to address the issue.]

Starting a new round of atmospheric sampling in the ISS interior, the FE deployed two passive FMK (formaldehyde monitoring kit) sampling badges in the Lab and SM, to catch any atmospheric formaldehyde on a sampling substrate for later analysis in JSC lab facilities.

Mike also sampled the environment for volatile compounds with the (relatively) new DST (Dual Sorbent Tube) equipment. [To supplement the sampling procedure, a 3-min training video was uplinked overnight for his review.]

Air sampling in the SM and Lab included a CO2 (carbon dioxide) partial pressure data take with the U.S. CDMK (CO2 monitor kit) by Mike Fincke for calldown to MCC-Houston (along with the battery status) for use in trending analyses, and another reading with the CSA-CPs (compound specific analyzer-combustion products) for O2 and CPs.

Gennady set up and worked a training session on the ADUM (Advanced Diagnostic Ultrasound in Microgravity) experiment, using the ADUM OPE (On-board Proficiency Enhancer), in preparation his ultrasound scanning activities next week.

Mike performed the routine maintenance of the SM’s SOZh life support system, conducted the regular routine status checkup of autonomously operating Increments payloads (today PCG-STES010), and prepared the daily “delta” file for updating the IMS (inventory management system) database(s).

TsUP/Moscow continues systems monitoring of the Soyuz TMA-4 crew return vehicle. Twice today, the CDR again took routine spacecraft parameter readings (Form 03) in the vehicle for calldown.

The crew went through a review of the U.S. procedures of the upcoming Orlan EVA, now scheduled for 6/24. Afterwards, they held a space-to-ground tagup with EVA personnel at Houston. [In support of the review, the ground uplinked material such as the detailed timeline and procedure for the RPCM R&R, an alternate patch panel reconfiguration procedure, and the cuff checklist pages for the RPCM R&R. Some issues are still being worked on the ground.]

At about 11:25am EDT, Padalka and Fincke had their weekly teleconference with the ISS Flight Director at MCC-H.

The crew completed their daily 2.5-hr. physical exercise program on TVIS treadmill, RED expander and VELO ergometer with load trainer.

For his regular “Saturday Science” feature, Mike Fincke has selected to conduct a teleconference on the BCAT-3 (Binary Colloid Alloy Test 3) experiment. A tagup with BCAT personnel will be held tonight at 5:05pm EDT. [In support of the event, POIC (Payload Operations & Integration Center) uplinked BCAT imagery and other material.]

Today’s CEO (Crew Earth Observations) photo targets, limited in XPOP attitude by flight rule constraints on the use of the science window, which is available for only ~1/4 of each orbit when not facing forward (in “ram”), were E Asia smog boundary, Sea of Japan (Dynamic event. Related to the North China Plain aerosol site mentioned yesterday, satellite images show a perceptible smog front extending east from Beijing, across Korea into the Sea of Japan [smog on the south side]. If this linear feature is apparent, the crew was to shoot obliques that include any dry land as a geographic anchor), Rome, Italy (nadir pass. Looking inland from the small but discernible Tiber River delta), Baghdad, Iraq (looking left where the rivers swing nearest to one another), Kuwait City, Kuwait (nadir pass. Although several good views have been acquired, there are none taken “nadirly” with the required lens), Hudson Bay ice (Dynamic event. Weather is finally clearing during daylight-awake hours: looking left, north of small James Bay into the open waters of Hudson Bay, more than 3 degrees north of track, to document the status of winter ice), and Saharan dust front, E Atlantic (Dynamic event. Satellite images show a perceptible dust front [dust on the south side]) where Algerian dust moves out over the African coast all the way to Puerto Rico. Suggested were views looking right to capture this feature if it persists. Trying to include the African coastline. Opportunity lasted for ~1.5 minutes, looking south trending to west).

CEO images can be viewed at the websites.
