NASA Satellite Crash: Van Allen Probe A Set to Fall to Earth
Parts of a giant NASA satellite, the Van Allen Probe A, are expected to crash to Earth on Tuesday evening, March 10, 2026, at approximately 7:45 PM EDT. The spacecraft, which weighs about 1,323 lbs (600 kg), is making its descent eight years ahead of the original projection of 2034.
The Van Allen Probe A was launched on August 30, 2012, as part of a mission to investigate the Van Allen belts of charged particles trapped by Earth’s magnetic field. However, the probes were deactivated in 2019 when they ran out of fuel, and now the satellite is on a collision course with Earth.
NASA has indicated that while the risk of harm coming to anyone on Earth is low, there is still a chance of debris striking individuals. The chance of being struck by debris from the satellite is estimated at 1 in 4,200, while the overall chance of anyone being hurt by falling debris is 1 in 3,200, according to a 2011 report.
NASA expects that most of the spacecraft will burn up as it travels through the atmosphere, but some components are anticipated to survive 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.” This highlights the extremely rare nature of such incidents.
Historically, instances of space objects harming people or property on the ground are extremely rare, but not unprecedented. Lottie Williams is the only person known to have been struck by falling manufactured space debris. Over a 40-year period, roughly 5,400 tons of debris are thought to have survived re-entry, showcasing the ongoing concern about space debris and its potential risks.
The second Van Allen Probe is not expected to re-enter before the end of this decade, allowing scientists to continue studying the data collected from the first probe. As the satellite approaches its re-entry, observers and experts will be monitoring the situation closely.
Details remain unconfirmed regarding the exact trajectory and potential impact zones of the debris. However, NASA continues to reassure the public about the low risk associated with the satellite crash, emphasizing that the majority of the spacecraft will disintegrate upon re-entry.
