NASA Space Station On-Orbit Status 3 June 2003

All ISS systems continue to function nominally, except as noted previously or below.
After his refresher course yesterday for the TEEM-100M gas analyzer and Cardiocassette-2000 instrument, CDR Yuri Malenchenko today started his first round of the Russian MBI-8 “Profilaktika” (countermeasures) fitness test series, on the VELO (stationary bike ergometer). FE/SO Edward Lu assisted. [Tomorrow, Day 2, the test will be performed on the Load Trainer, followed by the TVIS treadmill on Day 3 (Thursday). The test is identical to the Russian MO-5 assessment, but in addition to the nominal test procedure, it calls for the use of the TEEM-100M gas analyzer, measurement of the lactate level in the subject’s blood with the AccuSport device, and subjective evaluation of physical exertion levels during the test. Results were entered on a log sheet. TEEM and ECG (electrocardiograph) data were transferred to Laptop 3 and prepared for later downlink via Regul-Packet comm.]
Ed Lu completed the scheduled Week 5 water sampling for in-flight chemistry/microbiology analysis, using approved Russian sampling procedures with the U.S. WS&A (water sampler and archiver) for collection and the WMK (water microbiology kit) for processing within 6 hrs. of the collection. [Due to the high microbial counts during the last water sampling session, Lu was asked to take samples from all three potable water ports, viz., the SRV-K hot and warm ports (after preliminary heating of the water) and the EDV container of the water supply system (SVO-ZV). In-flight microbial analysis of these samples with the WMK was conducted later today, after the crew’s lunch break The MCDs (microbial capture devices) are also being incubated for two days, then visually analyzed for colony growth. On 6/5, after the analysis, the microbiological data can be either called down or entered in the MEC (medical equipment computer) for later downlink via OCA “email”.]
Malenchenko and Lu set up and reviewed the DOUG (dynamic operations ubiquitous graphics) software version for tomorrow’s 2.5 hours of SSRMS/Robotics operations. [DOUG is a periodically updated software program on the MSS (mobile service system) laptops that provides a birdseye-view graphical image of the external station configuration and the SSRMS (space station remote manipulator system) arm, showing its real-time location and configuration on a laptop during its operation. Tomorrow’s robotics ops, for honing crew proficiency, will consist of a maneuver to a pre-grapple position for the LAB FRGF (flight releasable grapple fixture), two grapples and releases, and then a maneuver to a stow position. Since there are two maneuvers and two grapples, it was suggested that Yuri and Ed each perform one maneuver and one grapple/release. Each maneuver will use both Joint OCAS (operator commanded auto sequence) maneuvers and Single Joint modes, chosen for the proficiency training since they are the most commonly used SSRMS modes.]
On MCC-Moscow/TsUP request, Yuri Malenchenko filmed a videotape recording of various scenes depicting the onboard life of the ISS crew, for showing to TsUP visitors. The footage was downlinked later by the automated daily timeline sequencer (SPP) over Russian ground sites (RGS) on Daily Orbit 2 (DO2). [TsUP-suggested scenes are sleep cabins and post-sleep wash-up of the crew, crew at work (showing activation and deactivation of payloads, transferring cargo, operating computers, working procedures, etc.), physical exercise, the Lada-2 greenhouse, and meal time.]
Malenchenko worked in the Service Module (SM), switching its audio subsystem (STTS), with its telephone/telegraph audio paths and comm stations, to its primary string. The VHF (very high frequency) transmitter #1 was left on the backup string. [The “Voskhod-M” STTS enables telephone communications between the SM, FGB, DC-1 and USOS (US segment), and also with users on the ground via STTS antennas on the outside of the SM and VHF channels selected by an operator at the SM comm panel. There are six comm panels in the SM with pushbuttons for accessing any of three audio channels plus an intercom channel.]
Ed Lu’s scheduled task to bring the EMER-1 and EMER-2 warning and emergency operations books up to date with latest change pages and P&I (pen and ink) updates, was deferred to a later time. [The third EMER-1 book which was lost in the Soyuz 5S orbital module, has meanwhile been reconstituted in its entirety. There must be three copies on board, one each in the Russian segment, U.S. segment, and Soyuz.]
Malenchenko performed another Russian segment (RS) inventory audit to update the IMS (inventory management system) database and searching for “lost” items. He also completed the daily routine maintenance of the SM’s SOZh environment control and life support system and later prepared the daily IMS inventory “delta” file.
Ed performed the monthly maintenance of the CEVIS (cycle ergometer with vibration isolation), which consists mostly of an examination of the wire rope isolators for damage.
Yesterday, CMG-2 (control moment gyroscope #2) experienced loss of communication with its MDM computer, was subsequently restarted, and is functioning nominally.
Since yesterday afternoon, the Node forward port IMV (intravehicular ventilation) fan is turned on for 15 mins. each day for eight consecutive days, in order to prevent the separation of bearing grease integral to the ventilator motor. Since the IMV valve outlet to the fan is closed, the fan is quite noisy during this time.
The crew was reminded that no discarded equipment and waste should be loaded in 10P/Progress-247, which remains attached at the SM aft-end port until 11/17 this year. Trash should be retained for 12P/Progress-259, which arrives at the station on 6/11. It then stays docked at the DC-1 “Pirs” docking module until 8/29, and must be fully loaded at its departure.
Today’s CEO (crew earth observation) targets, limited in the current XPOP attitude by flight rule constraints on the use of the Lab nadir/science window, also excluding any night target viewing, were Congo-Zimbabwe Biomass Burning (fires on both sides of the ground track. Also, a good opportunity for a glint image of the vast inland delta of the Okavango Swamp [green triangle of riverine forest, contrasted against the sand colors of the Kalahari desert]. Pattern of green changes as first one, then another branch of the delta becomes active), Lake Poopo, Bolivia (documentation of lake shorelines [which indicate water level accurately] is requested as the present El Nino climate pattern ends. The lake should have experienced significant drying in the last half year), La Paz, Bolivia (looking a touch left), Baghdad, Iraq (nadir pass), Eastern Mediterranean Aerosols (good pass from Sirte Gulf [Libya] through to western Turkey. Looking mainly left [especially northward up the Adriatic Sea] for haze in the Med basin. Haze masses interact with land and sea breezes set up by Italy and the Balkan coast), and Miami (nadir pass).
