ISS On-Orbit Status 14 Jun 2004<br /> <br /> All ISS systems continue to function nominally except those noted<br />previously or below. Underway: Week 7 for Increment 9. The crew had a<br />light Holiday schedule because of Russian Independence Day being observed by<br />our partners today.<br /> <br />After breakfast, CDR Padalka and FE/SO Fincke took turns in performing the<br />mandatory Russian pre-EVA MedOps procedure MO-6 (hand-cycle ergometry), each<br />providing pomosh' (assistance) to the other during the individual's 30-min.<br />test run. [Because previous cosmonauts have shown noticeable decrease in<br />arm muscle tone, TsUP/IBMP (MCC-Moscow/Institute of Biomedical Problems)<br />physical fitness experts have made the handgrip/arm tolerance test analysis<br />(hand ergometry) a standard pre-Orlan EVA requirement. MO-6 today required<br />the CDR, later the FE, to don the ECG (electrocardiogram) biomed harness,<br />attach three skin electrodes and plug the harness into the PKO medical exam<br />panel on the cycle ergometer. The exercise itself started after 10 seconds<br />of complete rest, by manually rotating the cycle's pedals, set at 150 W,<br />backwards until "complete exhaustion". It was supported by tagup with<br />ground specialists.]<br /> <br />In the Service Module (SM), Gennady Padalka started the regeneration cycle<br />on absorbent bed #2 of the BMP harmful impurities unit and switched channel<br />#1 from its 24-hr regeneration process back to Purify mode. [The "bakeout"<br />cycle for the filter beds is repeated every 20 days. Each bakeout to space<br />vacuum takes about 24 hours.]<br /> <br />Mike Fincke worked briefly in the Lab module, powering up EXPRESS Racks 3<br />and 5 (ER3, ER5) in preparation for the new software loads (Release 4)<br />scheduled for tomorrow (6/15).<br /> <br />The CDR conducted the routine maintenance of the SM's life support system<br />(SOZh), today including the regular weekly checkup on the BRPK<br />air/condensate water separator system, while Mike performed the regular<br />routine status checkup of autonomous Lab payloads, currently consisting of<br />PCG-STES010 (Protein Crystal Growth-Single Locker Thermal Enclosure System<br />#10).<br /> <br />The crew completed their daily 2.5-hr. physical exercise program on TVIS<br />treadmill, RED expander and VELO ergometer with load trainer. Mike also<br />performed the weekly TVIS maintenance, a five-minute task done usually just<br />prior to power-down or end of exercise session.<br /> <br />Working off the Russian discretionary task list, Gennady downloaded new<br />accumulated Matryoshka measurement tables from the Matryoshka server (BSPN)<br />via the ISS Wiener laptop to a PCMCIA memory card for subsequent downlink on<br />OCA comm. [Matryoshka automatically takes measurements in the SM and DC-1<br />docking compartment for studies of on-orbit radiation and long-term dose<br />accumulation, using six SPD dosimeters deployed throughout the Russian<br />segment as well as in a spherical body-simulating Matryoshka-R "phantom" and<br />a human torso model outside on the SM hull, mounted there during EVA-9.]<br /> <br />Update on Orlan EVA: In response to crew request, MCC-H uplinked a detailed<br />General Overview of EVA #4 (a.k.a. EVA 9A), scheduled for 6/24. The single<br />task priority of the spacewalk is the removal and replacement (R&R) of the<br />RPCM S02B-D to recover CMG-2 power supply, retaining the current "each CMG<br />on a separate RPCM" mode. If the R&R should fail, backup plan is a CMG<br />patch panel reconfiguration to connect CMG-2 to an adjacent RPCM, which puts<br />two CMGs on the same RPCM. Time for the RPCM-specific work is estimated at<br />2.5 hrs. Translation and setup/cleanup of the Strela boom (connecting DC-1<br />with FGB) will require another 1.5 hrs. Total EVA time is constrained by<br />Orlan consumables to 6 hrs (hatch open to hatch close). In preparation for<br />the EVA, the required complex crew sleep cycle shifting will begin on 6/16<br />(Wednesday), with sleep/wake times 1.5 hr earlier than regular (for the MO-5<br />cardiovascular training on 6/17), followed by a workday stretching by 1.5 hr<br />on 6/21 for Orlan checkout via telemetry over RGS, another sleeptime delay<br />of 2.5 hr. on 6/22 for the Orlan exercise, an off-duty rest day on 6/23 with<br />a sleeptime slip of 1 hr to 11:30pm EDT, and wakeup at 9:30am on EVA day,<br />6/24, (instead of the regular 2:00am). Today's CEO (Crew Earth<br />Observations) photo targets, limited in XPOP attitude by flight rule<br />constraints on the use of the science window, which is available for only<br />~1/4 of each orbit when not facing forward (in "ram"), were Plankton bloom,<br />Yellow Sea (Dynamic event. From ISS track along the Chinese coastline,<br />looking left to document changes in the offshore bloom), Shanghai, China<br />(looking left for general views of the Shanghai region. The city lies on<br />the south side of the estuary, 50 km from the open sea), Internal waves,<br />Sulu Archipelago (looking far right for any internal waves off the coast of<br />Borneo), Lahore, Pakistan (nadir pass over this major Pakistani city),<br />Internal waves, Aegean Sea (looking far right for any internal waves among<br />the southernmost Greek islands), Nile River Delta (a nadir/near nadir<br />mapping swath across the delta [~45 secs], to document land-use change, was<br />requested), and Florida: East and West Coast (looking far right for any<br />internal waves on the gulf side of the Florida peninsula).<br /> <br />CEO images can be viewed at the websites.<br /> <br /> <br />http://eol.jsc.nasa.gov<br />http://earthobservatory.nasa.gov<br /> <br />See also the website "Space Station Challenge" at<br /> <br /> <br />http://voyager.cet.edu/iss/<br /> <br />U.S. & Russian Segment Status (as of today, 12:26pm EDT)<br /> <br />Environmental Control and Life Support (ECLSS) and Thermal Control (TCS):<br /> <br />Elektron O2 generator is On.
