The Upper Atmosphere Research Satellite hangs in the grasp of the Remote Manipulator System against the blackness of space during deployment from Space Shuttle Discovery, September 1991.
This map shows the ground track for UARS beginning in the Indian Ocean off the coast of Africa at 0330 GMT and ending at atmospheric interface over the Pacific Ocean at 0401 GMT. In this map, UARS' path is shown beginning in the Indian Ocean off the coast of Africa at 0330 GMT and ending at atmospheric interface over the Pacific Ocean at 0401 GMT.
Astrophotographer Ralf Vandebergh captured the UARS spacecraft tumbling through space, and noted: "Through the clouds I was able to grab just enough frames for an image of UARS on Sept 17, in the week before the expected reentry. Note the striking yellow (golden) color of the elongated main body and some smaller detail with different colors. Due to the shift, (maximum 62 degrees altitude), the distance was still over 270 km."
Skywatcher Adrian New captured this image of NASA's falling UARS satellite as it flew over San Antonio, Texas at 9:20 p.m. EDT on Friday, Sept. 23 (0120 Sept. 24 GMT).
Thierry Legault is part of a network of skywatchers armed with sophisticated astronomical gear to monitor the whereabouts of spacecraft.
The ground track of NASA's UARS re-entry shows where the defunct satellite was passing over just before it fell to Earth. The circle presents the most likely point of landing, which probably occured around 12:16 a.m. EDT (0416 GMT) on Sept. 24.
