NASA Satellite Falling to Earth Today: Where Will it Land?
A 1,300-pound NASA spacecraft is making an uncontrolled return to Earth after nearly 14 years in orbit — and the agency cannot pinpoint exactly where debris might land.
The Van Allen Probe A Is Coming Down
NASA has been tracking Van Allen Probe A and predicts it will reenter the atmosphere around 7:45 p.m. ET on Tuesday, though that window could shift by as much as 24 hours in either direction. The US Space Force, which has also been monitoring the probe, confirmed the projected reentry time remains an estimate and will be refined as new tracking data becomes available.
Because the spacecraft is traveling thousands of miles per hour and the reentry window spans nearly a full day, scientists cannot calculate a precise landing zone.
Should Anyone Be Worried?
NASA says the risk to the public is extremely low. The agency estimates the probability of anyone being harmed by falling debris at roughly 1 in 4,200, or about 0.02 percent. Most of the spacecraft is expected to burn up as it streaks through the atmosphere. Any components that survive reentry are most likely to land in open water, since oceans cover approximately 70 percent of Earth's surface.
Why Is It Falling Now?
The spacecraft's mission officially ended in 2019 after it ran out of fuel and could no longer orient itself toward the sun. At that point, scientists expected it to fall back to Earth around 2034.
That timeline changed significantly when the sun proved far more active than anticipated. In 2024, scientists confirmed the sun had reached its solar maximum, generating intense space weather that increased atmospheric drag on the probe and accelerated its descent by roughly a decade. The spacecraft has been gradually losing altitude ever since.
What Did the Van Allen Probes Actually Do?
Van Allen Probe A launched alongside its twin, Van Allen Probe B, on August 30, 2012. For nearly seven years, the two spacecraft flew through the Van Allen belts — rings of charged particles trapped by Earth's magnetic field — collecting data on how particles were gained and lost within those regions.
The Van Allen belts play a critical role in protecting Earth from cosmic radiation, solar storms, and the constant stream of charged particles known as solar wind. All of these pose risks to humans and can damage satellites, communication systems, navigation infrastructure, and power grids.
NASA has described the data gathered by the probes as unprecedented, and researchers continue to study the archived findings today. The mission contributed to improved forecasts of space weather events and a better understanding of how solar activity affects technology both in orbit and on the ground.
What Happens Next
NASA and the US Space Force will continue refining reentry predictions in the hours ahead as fresh tracking data comes in. The agency has not issued any public safety warnings given the low probability of harm.
Van Allen Probe B, the mission's second spacecraft, remains in orbit and is not expected to reenter Earth's atmosphere before 2030.
