Van Allen Probe A, a 1,300-pound (600 kg) NASA satellite [1]launched in 2012 to study Earth's radiation belts, is [2]expected to re-enter Earth's atmosphere this week . While most of it is expected to burn up during descent, "some components may survive," reports the BBC. "The space agency said there is a one in 4,200 chance of being harmed by a piece of the probe, which it characterized as 'low' risk." From the report:
> The spacecraft is projected to re-enter around 19:45 EST (00:45 GMT) on Tuesday the U.S. Space Force predicted, according to Nasa, though there is a 24-hour margin of "uncertainty" in the timing. [...] The spacecraft and its twin, Van Allen Probe B, were on a mission to gather unprecedented data on Earth's two permanent radiation belts. It was not immediately clear where in Earth's atmosphere the satellite is projected to re-enter. NASA and the U.S. Space Force has said it will monitor the re-entry and update any predictions. [...] Van Allen Probe B is not expected to re-enter the Earth's atmosphere before 2030.
