A NASA spacecraft could crash into the Earth today. The chances of it hitting someone are tiny, but not zero

"In 2012, NASA launched two probes into space: Van Allen Probe A and Van Allen Probe B. Their goal was to collect data on charged particles passing through Earth's magnetic field. Those particles can wreak havoc on communications and other technologies on our planet, so understanding them is important."

"That one is the Van Allen Probe A. The Van Allen Probe B isn't scheduled to reenter earths atmosphere until at least 2030. Still, that means there is one 1,323-pound space object expected to hit Earth within the next 24 hours. The good news is that NASA says much of the probe is expected to burn up upon reentry."

"NASA says the Van Allen Probe A is expected to reenter the Earth's atmosphere at around 7:45 p.m. EDT on March 10-'with an uncertainty of +/- 24 hours.' However, the space agency does caution that 'some components are expected to survive re-entry' as well."

NASA launched the Van Allen Probes in 2012 to collect data on charged particles in Earth's magnetic field, which can damage communications and technology. The mission ended in 2019 when fuel was depleted. Van Allen Probe A is now reentering Earth's atmosphere around 7:45 p.m. EDT on March 10 with a 24-hour uncertainty window. While most of the 1,323-pound probe is expected to burn up during reentry, NASA cautions that some components may survive and potentially reach Earth's surface. Van Allen Probe B is not scheduled to reenter until at least 2030.
