Reentry

关注

NASA's Van Allen Probe A satellite, launched in 2012 to study Earth's radiation belts, is set to reenter the atmosphere early this week after running out of fuel in 2019. The agency has approved a safety waiver due to the reentry's risk exceeding government standards, though the chance of harm remains low at 1 in 4,200. Most of the 1,323-pound spacecraft will burn up, with some debris potentially reaching the surface.
