NASA Satellite Crash: Van Allen Probe A Set to Re-enter Earth
Parts of a giant NASA satellite, the Van Allen Probe A, are set to crash to Earth on Tuesday evening, March 10, 2026, at approximately 7:45 p.m. EDT. NASA has assessed the risk of harm to people as low, estimating the chance of being harmed by falling debris at 1 in 4,200.
The Van Allen Probe A, which weighs about 1,323 pounds (600 kg), was launched on August 30, 2012, to study the Van Allen radiation belts that protect Earth from solar storms and cosmic radiation. The spacecraft, along with its twin, was deactivated in 2019 after running out of fuel, marking the end of its operational life.
NASA officials have indicated that while most of the craft is expected to burn up upon re-entry, some components may survive the descent through the atmosphere. The overall chance of anyone being hurt by falling debris is estimated at 1 in 3,200, further emphasizing the low risk associated with this event.
Approximately 71% of Earth’s surface is covered by water, which significantly reduces the likelihood of debris hitting land. This geographical factor plays a crucial role in mitigating potential risks associated with the satellite’s re-entry.
Mark Matney, a NASA official, stated, “The odds that you will be hit are one in several trillion, so quite low for any particular person.” He also noted that most material should burn up in the atmosphere, reinforcing the safety measures in place for this event.
NASA and the U.S. Space Force will continue to monitor the re-entry and update predictions as necessary. The initial uncertainty in re-entry predictions is plus or minus 24 hours, which means that observers are keeping a close watch on the satellite’s trajectory.
Debris falling from space is not uncommon, with roughly 5,400 tons thought to have survived re-entry over the past 40 years. However, the Van Allen Probe B, its twin, is not expected to re-enter before the end of this decade, allowing for further study of the radiation belts.
As the re-entry date approaches, details remain unconfirmed regarding the exact location of any potential debris landing. NASA continues to provide updates to ensure public safety and awareness surrounding this event.
