ISS On-Orbit Status, 08-07-2003
ISS On-Orbit Status 8 Jul 2003
All ISS systems continue to function nominally, except as noted previously or below. Day 75 in space for the crew. Using the MO-21 "Ecosfera" air sampler and incubation equipment, broken out and set up yesterday, CDR Malenchenko spent about 40 minutes collecting air samples for atmospheric microbial analysis. [MO-21 determines microbial contamination of the ISS atmosphere, specifically the total bacterial and fungal microflora counts and microflora composition according to morphologic criteria of microorganism colonies.] Malenchenko then worked on restoring the Russian laptop 1 to functionality by first creating a boot-up floppy disk (for Norton Ghost 5.1D) on Russian laptop 2. Later, he activated laptop 1, installed a software patch and "cloned" a new HDD (hard disk drive) on the machine from the Norton Ghost 5.1D disk obtained from laptop 2. FE/SO Ed Lu meanwhile spent time in the U.S. segment (USOS) with the regular periodic inspection of smoke detectors in the Lab module, Airlock (A/L) and Node "Unity", as well as of the A/L's microbial filter. Yuri Malenchenko completed the scheduled installation of new satellite navigation equipment (ASN), delivered on Progress 11P, in the Service Module (SM). [The ASN was connected to the onboard computer system's laptop 3, configured for the subsequent test. After he had mated BITS2-12 onboard measurement telemetry system connectors to the ASN, a raw data transfer test to laptop 3 was to be conducted from TsUP by remote control.] The CDR attended to the routine maintenance of SOZh life support systems, while Ed Lu prepared the daily IMS (inventory management system) "delta" file for updating the IMS database and completed the regular daily status checkup of the autonomous Lab payloads.. Ed also attended to the weekly transfer of accumulated data files with workout data from the TVIS and RED exercise equipment to the MEC via PCMCIA cards (personal computer memory card international association) for subsequent downlink to Earth. At 5:45am EDT, both crewmembers participated in an interactive televised PAO/educational event sponsored by NASDA, with Japanese middle school students gathered at the Tokyo FM Radio station banquet hall (Ku- & S-band). Former NASDA Astronaut Mamoru Mohri attended. Both crewmembers completed their daily physical exercise program (2.5 hrs.) on TVIS treadmill, CEVIS cycle ergometer, and RED anaerobic exerciser. The Science Officer changed lenses of the EarthKAM (EK) camera at the Lab nadir window from 50mm to 180mm. EK team reported an excellent startup yesterday, and the on-board system is working well. [Attending today's and tomorrow's National Geographic Society-sponsored sessions are 25 students, ranging from 5 th grade to college sophomores. Commented one of their teachers: "I can't think of another program that interests and excites students to the point that they are willing to come in during vacation (some home from college), to work during a mission." EarthKAM (Earth Knowledge Acquired by Middle school students) employs an ESC 460C electronic still camera mounted at the Lab's down-facing window, normally equipped with a 50mm lens (f1.4). Powered by 16Vdc from a 120 Vdc adapter, EarthKAM takes pictures by remote operation from the ground, without crew interaction. It is available for Middle School-ers, who submit image requests and conduct geographic research. The requests are uplinked in a camera control file to an SSC (station support computer) laptop which then activates the camera at specified times and receives the digital images from the camera's storage card on its hard drive, for subsequent downlink via OpsLAN.] The Kodak 760 ECS (electronic still camera) used by Ed Lu to photograph stunning aurora images has shown some noise, due to "pixelation" or "hot pixels" not properly removed or blended into the image by the automatic camera procedure. The most probable cause is excessive radiation as ISS passed through the aurora. All noise will be removed from the photos by ground processing. Today's CEO targets, no longer limited in the current LVLH attitude and including the targets of the Lewis & Clark 200-year memorial locations, were Baghdad, Iraq (nadir pass), Phoenix, AZ (NIGHT TARGET: nadir pass), Lisbon, Portugal (nadir pass), Pomeroy, Washington (LEWIS & CLARK SITE: Nadir pass--looking on the south side of the Snake River [within the second bend of the river upstream of its confluence with the Columbia River]), Lemhi Pass, Mont/Idaho (LEWIS & CLARK SITE: Nadir pass--shooting mountain range crests [dark forest green, as opposed to lighter, browner river valleys] and the crew should have gotten this now-unused pass over the continental divide. The explorers crossed here into Idaho on August 12, 1805. Lemhi Pass was abandoned for the westward migrations since other lower passes exist), Denver, Colorado (nadir pass), and Los Angeles, California (nadir and a touch left).
