NASA's Van Allen Probe A to make uncontrolled reentry March 10 after nearly 14 years
NASA's 600 kg (1,323 lb) Van Allen Probe A is expected to make an uncontrolled reentry on March 10 after almost 14 years in orbit. Launched in 2012 as part of a twin mission to study Earth's radiation belts, the spacecraft carries an estimated 1-in-4,200 chance of causing harm on the ground.
