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. -------------------- |

The Earth Radiation Budget Satellite -- launched by Shuttle in 1984 -- is also finally about to be turned off. It's a measure of how difficult it is to study global warming without satellites that, until ERBS, we were in the dark about even such a fundamental question as whether Earth's current cloud cover is warming or cooling the planet! (The answer, provided by a few years of ERBS observations, is that it is significantly cooling us.)
