A roughly 1, 323-pound spacecraft named Van Allen Probe A is nearing the end of nearly 14 years in orbit, and for many the moment has narrowed to a single predicted window. Nasa Satellite Crashing is now forecast to occur around 7: 45 pm ET on March 10, 2026, a projection the U. S. Space Force issued with a plus-or-minus 24-hour uncertainty.
Van Allen Probe A: what the spacecraft will face on re-entry
Van Allen Probe A launched in 2012 and collected data through 2019. The mission was originally designed to last two years but continued operating for almost seven before the spacecraft ran out of fuel and could no longer orient toward the Sun. Most of the probe is expected to burn up as it travels through the atmosphere, but NASA has said some components may survive re-entry.
Officials have described the risk to people on the ground as low. The chance of harm from any surviving debris is roughly one in 4, 200, and the probe’s mass—roughly 1, 323 pounds—shapes both burn-up behavior and what might reach the surface.
U. S. Space Force and Nasa Satellite Crashing prediction for March 10
The U. S. Space Force predicted the re-entry time as approximately 7: 45 pm ET on March 10, 2026. That estimate carries an uncertainty of +/- 24 hours, and NASA and the Space Force will monitor the probe closely and update predictions as new data arrive. As of March 9, 2026, the public timeline centers on that window.
Atmospheric drag changed earlier forecasts. Calculations made when the mission ended had placed re-entry years later, but increased solar activity and a stronger atmosphere raised drag enough to hasten the probe’s descent. Those conditions shifted the expected return from the date initially projected to the current March 10, 2026 window.
Van Allen Probes’ mission legacy and what this return reflects
The two spacecraft, Van Allen Probe A and its twin Van Allen Probe B, operated from 2012 until 2019 to study Earth’s permanent radiation belts. Their work provided data on how particles are gained and lost in those belts and produced the first evidence of a transient third radiation belt during periods of intense solar activity.
Van Allen Probe B is not expected to re-enter before 2030, leaving one probe to return earlier than once calculated. Scientists continue to use archived data from the mission to study space weather and its effects on satellites, astronauts, and ground systems such as communications and power networks.
For people on the ground, the most immediate consequence is observational: tracking and timing. For mission teams, the event offers a live example of how solar activity and atmospheric conditions alter long-term orbital forecasts.
Closing where this story began, Van Allen Probe A—the 1, 323-pound craft launched in 2012—remains on a final trajectory toward the atmosphere. NASA and the U. S. Space Force will continue monitoring and will publish updated predictions as they become available, centered on the projected 7: 45 pm ET on March 10, 2026 re-entry window with its 24-hour margin of uncertainty.
