The Upper Atmospheric Research Satellite, deployed Sept. 12 1991 from the Space Shuttle Discovery, was decomissioned today. It's last good battery shorted out in August and planning to end the mission went as planned and concluded today with the shutting down of the satellite. Last week, a several-minute burn lowered the orbit of the satellite.
It is expected to make an uncontrolled reentry in 2008 or 2009. UARS opened a wealth of understanding on the upper and lower atmospheric layers including monitoring the ozone layer. -------------------- |

I don't know if aero.org does any independent analysis or just works off of http://www.nasa.gov/mission_pages/uars/index.html. Unfortunately they have not updated from report #10 at 10:45 am EDT this morning. Maybe they are waiting until one orbit left to post...

Just some more details...
Latest update as of 2215 UTC, demise is ~ 7 hours away (3 hours now), and the US is finally off the table. Orbit at that time (about 4 hours ago) was 145 x 150 km (90 x 93 mi). Down 17 and 20 km in the preceeding 12 hours. Estimated crash time is 0510 UTC Sept 24 +/- 2 hours, over the very south Pacific west of Australia, although the earlier and later orbits include Canada, Africa and Australia of the landmasses. MW |
