An old NASA science satellite is no more
CAPE CANAVERAL, Fla. -- An old NASA science satellite plunged uncontrolled from orbit and reentered over the Pacific on Wednesday.
The U.S. Space Force said the Van Allen Probe A came in west of the Galapagos Islands.
NASA expected some of the 1,323-pound (600-kilogram) spacecraft to survive entry, with most of it burning up in the atmosphere. The space agency put the risk of bodily harm at 1-in-4,200.
Its twin, the Van Allen Probe B, is still orbiting Earth, but no longer functioning.
Launched in 2012, the two spacecraft flew through the Van Allen radiation belts that surround Earth, studying them for seven years before ceasing operation.
