NASA Satellite's Fiery Return to Earth
10 Mar
Summary
- NASA's 1,300-pound Van Allen Probe A set for atmospheric re-entry.
- The probe studied Earth's radiation belts for nearly seven years.
- Debris poses a low risk to Earth, with odds of harm at 1 in 4,200.
NASA's Van Allen Probe A, weighing 1,300 pounds, is nearing the end of its 14-year mission with an anticipated re-entry into Earth's atmosphere. The probe, along with its twin, was launched in August 2012 to study the planet's radiation belts.
For nearly seven years, the Van Allen Probes collected vital scientific data on these radiation zones, which pose significant hazards to future space travel. Their mission concluded in 2019 when they depleted their fuel, rendering them unable to maintain their orbits or power. Despite this, their research significantly advanced NASA's understanding of space weather.
Recent predictions from the U.S. Space Force indicate re-entry around Tuesday, March 10. NASA anticipates that most of the spacecraft will disintegrate during its atmospheric descent. The agency has assessed the risk to people on Earth as minimal, estimating the odds of harm at about 1 in 4,200. The other probe, Van Allen Probe B, is not expected to re-enter before 2030.
