The Aerospace Corporation Confirms Reentry of UARS

EL SEGUNDO, Calif. (Sept. 24, 2011) — NASA’s decommissioned Upper Atmospheric Research Satellite (UARS) has fallen back to Earth, according to systems monitoring the satellite at The Aerospace Corporation.

“An event like this is very exciting to us at Aerospace because there is a great opportunity to learn something new,” said Dr. Bill Ailor, director of Aerospace’s Center for Orbital and Reentry Debris Studies (CORDS). “The more we know, the better we are able to manage and minimize the risks debris poses to space missions and to people and property.”

Monitoring stations lost track of the satellite after it began to burn up on reentry. Modeling indicates that the debris likely fell to Earth off the southwest coast of Australia between 8:23 and 10:09 PDT.

This is consistent with predictive modeling done at CORDS.
