ISS On-Orbit Status, 27-06-2004
ISS On-Orbit Status 27 Jun 2004
All ISS systems continue to function nominally except those noted previously or below. Sunday rest aboard ISS. Ahead: Week 9 for Increment 9. After breakfast, CDR Gennady Padalka worked on the Orlan-M spacesuits used for the aborted EVA on 6/24, setting up the ZU-S battery chargers, then successively initiating recharging of the two 825M3 Orlan backpack batteries to ready them for the next try on 6/30. To allow monitoring of the procedure from the ground, Padalka first hooked up the Service Module (SM)'s BITS2-12 onboard telemetry system. After their one-hour lunch break (starting 7:44am EDT), the crew performed the weekly 3-hr. station cleaning, postponed from yesterday. ["Uborka" includes removal of food waste products, cleaning of compartments with vacuum cleaner, wet cleaning of the Service Module (SM) dining table and other surfaces with "Fungistat" disinfectant and cleaning fan screens to avoid temperature rises.] The CDR completed the daily routine maintenance of the SM SOZh life support system (including ASU toilet facilities), which today also involved the weekly data collection of the SM's toilet flush counter readings, with inspection of the urine collection (SP) & pretreat assembly and water supply status (SVO) counter readings, both for calldown to TsUP/Moscow. Padalka and Fincke completed their full daily physical exercise program on CEVIS cycle ergometer, TVIS treadmill, RED resistive expander and VELO bike with force loader. For today's amateur radio "Field Day" all over the world, the ISS crew was provided with rise times for participating, at their option, with the onboard "Sputnik-SM" ham radio equipment. Times for North and South America were uplinked to Mike Fincke. Gennady worked another task-listed session of the Russian Uragan earth-imaging program, using the Kodak 760 DSC (digital still camera) with 200-, 400- and 800mm-lenses from SM window #9, now available again in LVLH attitude. After the activities, he commanded the external window shutter closed again. The images were transferred from the camera's PCMCIA memory card to the TP2 laptop. [Today's task featured imagery of the city of Accra and coast of Ghana, Lesotho, a panoramic view of the Rockies, the cities of Milwaukee and Chicago, a panorama of the Amazon estuary, the Tristan da Kunha Islands, and panoramic shots of Sao Paolo and the coastal area.] Also on Gennady's task list today was another session of the "Diatomeya" ocean observations program, using the DSR PD-150P video camera and Nikon F5 digital still camera with 24/85-mm lens to collect photo and video data on bioproductive regions (algae blooms) confined to largest morpho-structures in Atlantic and Indian Ocean bed contours. [Uplinked suggested targets today specified the North Atlantic in the Mid-Atlantic Ridge area and the region over the western slope of the North American Depression.] Using the Nikon D1 (800mm-lens), the CDR then took areal photography for Russia's Environmental Safety Agency (ECON). [Target region for today was the Pacific Ocean.] As a long-term recurring item on the Russian task list, Padalka was again charged with taking photographs of the PKZ-1V Kromka experiment tablet deployed on the plume deflector of the SM's plus-pitch thrusters. (Last time done: 5/29) [The pictures are shot with the Kodak 760 digital still camera (DSC) from the EVA hatch #1 in the DC-1 docking compartment.] Today's optional CEO (Crew Earth Observations) photo targets, in the current LVLH attitude no longer limited by flight rule constraints on the use of the Lab nadir/science window, except for the shutter closure and condensation-prevention plan (limited to 90 min. in 24 hours), were Tigris-Euphrates, Turkey (nadir pass over the middle of the site: look for the new and filling lakes with associated infrastructure, such as farms and roads), Baghdad, Iraq (nadir pass), Chicago, Illinois (pass crossed the north end of Chicagoland: good opportunity to image northern suburbs of the city), Denver, Colorado (more than one image was probably needed to acquire the city at the requested resolution), Fans, southern Amazonia, Brazil (if weather remained relatively clear, the crew was asked to shoot a diverging pattern of unusual sinuous white lines visible in the rainforest. These faint lines were first recognized from handheld imagery and have been interpreted as meandering, north-flowing river courses. The courses are interpreted as a megafan lying between the Brazilian hill country and the Madeira River, and gave rise to the successful prediction that other megafans would be discovered in similar settings in Amazonia.) CEO images can be viewed at the websites. http://eol.jsc.nasa.gov http://earthobservatory.nasa.gov See also the website "Space Station Challenge" at http://voyager.cet.edu/iss/ ISS Orbit (as of this morning, 9:15am EDT [= epoch]): Mean altitude -- 360.6 km Apogee -- 364.3 km Perigee -- 356.9 km Period -- 91.8 min.
