Explore the latest developments concerning NASA’s Van Allen.
NASA’s Van Allen Probe A to Re-Enter Atmosphere
NASA’s Van Allen Probe A is expected to re-enter Earth’s atmosphere almost 14 years after launch. From 2012 to 2019, the spacecraft and its twin, Van Allen Probe B, flew through the Van Allen belts, rings of charged particles trapped by Earth’s magnetic field, to understand how particles were gained and lost. The belts shield Earth from cosmic radiation, solar storms, and the constantly streaming solar wind that are harmful to humans and can damage technology, so understanding them is important.
As of March 9, 2026, the U.S. Space Force predicted that the roughly 1,323-pound spacecraft will re-enter the atmosphere at approximately 7:45 p.m. EDT on March 10, 2026, with an uncertainty of +/- 24 hours. NASA expects most of the spacecraft to burn up as it travels through the atmosphere, but some components are expected to survive re-entry. The risk of harm coming to anyone on Earth is low — approximately 1 in 4,200. NASA and Space Force will continue to monitor the re-entry and update predictions.

Parts of a giant Nasa satellite will crash to Earth on Tuesday evening, the US space agency is warning – but the chance of being struck is extremely low.
According to the US military’s space force, the roughly 1,323lb (600kg) spacecraft, one of a pair of twin probes launched in 2012 to investigate the Van Allen radiation belt, is estimated to re-enter Earth’s atmosphere at about 7.45pm EDT.

Nasa spacecraft weighing 1,300lb due to re-enter Earth's atmosphere
A Van Allen Probe spacecraft weighing more than 1,300lb (600kg) is expected to re-enter Earth's atmosphere almost 14 years after its launch, Nasa says.
The spacecraft is projected to re-enter around 19:45 EDT (23:45 GMT) on Tuesday the US Space Force predicted, according to Nasa, though there is a 24-hour margin of "uncertainty" in the timing.
The Van Allen Probe A, which launched in 2012, is expected mostly to burn up as it travels through the atmosphere, though some components may survive.
The space agency said there is a one in 4,200 chance of being harmed by a piece of the probe, which it characterised as "low" risk.
