NASA Satellite Crash Update
The Van Allen Probe A, a 1,300-pound NASA satellite, is expected to reenter Earth’s atmosphere around 7:45 p.m. on March 10, 2026. There is a 24-hour margin of uncertainty for the reentry time, but NASA officials have indicated that most of the probe is likely to burn up during reentry.
Despite the expected disintegration, some components of the satellite may survive the descent. NASA officials have assessed the risk of harm to anyone on Earth as low, estimating a chance of approximately 1 in 4,200.
The Van Allen Probe A was launched in August 2012, originally intended for a two-year mission to explore Earth’s permanent radiation belts. However, the mission lasted nearly seven years, concluding in 2019 when the probes ran out of fuel.
These probes were designed to study the Van Allen belts, which are crucial for shielding Earth from cosmic radiation, solar storms, and solar wind. The current solar cycle has increased atmospheric drag on the spacecraft, pulling them in faster than expected.
Probe B, its counterpart, is not anticipated to re-enter Earth’s atmosphere until the 2030s, specifically around 2034. The probes were the first to spend a significant amount of time in the radiation belts, which are rings of charged particles trapped by Earth’s magnetic field.
NASA officials noted, “The risk of harm coming to anyone on Earth is ‘low’ at approximately 1 in 4,200.” This assessment provides some reassurance as the satellite prepares for its final descent.
Most missions to the Van Allen belts are typically short to minimize exposure to damaging radiation, highlighting the unique nature of the Van Allen Probe mission.
As the reentry date approaches, observers will be monitoring the situation closely, with expectations that the satellite will safely disintegrate upon reentry. Details remain unconfirmed regarding the exact location of any surviving debris, which is likely to land in a body of water.
