The 600-pound RHESSI spacecraft is expected to reenter on Wednesday (April 19) at 9:30 p.m. ET, plus or minus 16 hours.
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 around 9:30 p.m. EDT on Wednesday , plus or minus 16 hours, according to the latest estimates by the U.S. military.. It weighs just 600 pounds , and the majority of that mass will be converted to ash and vapor during RHESSI's death dive, NASA officials said.."The risk of harm coming to anyone on Earth is low — approximately 1 in 2,467."RHESSI's coming plunge is another reminder that Earth orbit is an increasingly crowded and dangerous place.
Even these tiny shards can do serious damage if they hit a satellite or a crewed spacecraft , given their tremendous velocities: In low Earth orbit, where theAnd in-space collisions generate many more pieces of space junk, which could lead to more collisions down the road. If enough of those happen, we'd end up with a dreaded cascade known as the
