ISS On-Orbit Status 18 Nov 2003
All ISS systems continue to function nominally, except as noted previously or below. As of this morning, the station has circled Earth 28512 times, having put 755 million miles (1.2 billion km) behind it -- or roughly the distance to Jupiter. Today's crew activities centered on the Russian Orlan IVA training run, involving a test of retreating, in pressurized spacesuits, from the DC-1 airlock to the Soyuz CRV (crew return vehicle) docked to the DC-1 "Pirs". The exercise was to demonstrate, for the very first time, the crew's ability to access the Soyuz Orbital Module (BO) in the event of a contingency during or after the two-man EVA planned for early next year (there have been no ground sims of this maneuver in the Russian Hydrolab). Both spacesuits and their ancillary systems were assembled and checked out properly. But after a preliminary fit check of an inflated Orlan suit pushed by the crew through the DC1-to-BO hatch last night indicated marginal clearance, TsUP/Moscow changed the training procedure by having only FE Kaleri suit up. As it appeared on the downlinked video, his transfer to the Soyuz BO module through the tight hatchway in the pressurized Orlan seemed to require active pushing by CDR Foale, himself remaining unsuited. Russian specialists are now assessing the test and are expected to develop conclusions and further plans, which could include a relocation of the Soyuz to the roomier FGB nadir hatch. Today's IVA training run took more time than expected, and the option of doing selected get-ahead tasks, provided to the crew in case of "left-over" time on today's schedule, was not exercised. A planned ground-commanded external video survey of the ISS with the SSRMS (Space Station Remote Manipulator System) cameras, requiring no crew involvement, was deferred to a future date (TBD). 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, wereSabancaya volcano, Peru (this landslide research site lies just right of track; a short mapping swath to capture the site was suggested. Landslides cause far more destruction to communities in the Andes than volcanoes or earthquakes per se), La Paz, Bolivia(looking left for this city on the lip of the high Andean plateau),Lake Poopo(good pass over the Poopo basin. The crew's recent successful images of the lake itself showed that secondary features need to be imaged, especially the white, dry lake beds south of Poopo, which will appear just right of rack. These usually dry lakes receive some of the overflow from Poopo, and are a sensitive indication of rainfall in the basin), and NE Brazil Biomass Burning(Dynamic event. Looking mainly left for continuing fires and smoke). 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/ U.S. and Russian Segment Status (as of 1:00pm EST).

What is the procedure for moving a Soyuz? Do they both get in wearing
less bulky flight suits and fly it to the other port? Yes. If there were a failure to re-dock, they wouldn't want someone to be stranded. If so, doesn't that technically leave ISS unmanned? (sorta like Dan Quayle being the 42nd President of the US because he took over for a few hours while Bush Sr. was under anesthesia ![]() Something like that. Or like leaving your house uninhabited because you step out onto the front stoop to pick up the newspaper. They can't move a Soyuz by remote control, can they? That's actually a good question. They have the hardware, which is used on Progress. But (a) I don't know if it is installed on Soyuz, and (b) they'd probably feel that a human pilot would be a bit more reliable. |

Does moving it affect its 6 month "shelf life" at all? Thanks, Dale |

I know they have moved Progresses to make room for soon-to-arrive Shuttles and such, but I can't recall them ever getting in a Soyuz and moving it. Yes, I know the Expedition 2 crew did a Soyuz relocation, and there may have been others I don't remember. Does moving it affect its 6 month "shelf life" at all? No, once the descent module propellant is loaded, the clock is ticking on that one. It does affect the Soyuz 4.2 day "free-flight" limit, though. -- JRF Reply-to address spam-proofed - to reply by E-mail, check "Organization" (I am not assimilated) and think one step ahead of IBM. |
