NASA's falling satellite is expected to meet its demise within the next two hours, making a destructive dive back through the atmosphere between 11:45 p.m. tonight and 12:45 a.m. Saturday.
The Upper Atmosphere Research Satellite is now at an altitude of 90 to 95 miles, and the spacecraft will be passing over Canada and Africa, as well as vast areas of the Pacific, Atlantic and Indian oceans when the spacecraft reenters the atmosphere.
NASA expects most of the satellite to burn up during atmospheric reentry. But 26 spacecraft components weighing a combined total of 1,200 pounds were expected to survive and strike Earth.
The risk to public safety is remote.
Odds of a single person, somewhere on the planet, being struck: 1 in 3,200.
