A dead NASA spacecraft will come crashing back to Earth in the next few days, experts say.
NASA's RHESSI satellite, which studied the sun from 2002 until its decommissioning in 2018, is expected to reenter Earth's atmosphere around 9:30 p.m. EDT on Wednesday (April 19; 0130 GMT on April 20), plus or minus 16 hours, according to the latest estimates by the U.S. military.
