NASA Satellite Set for Fiery Reentry After 14 Years in Space
A 1,300-pound NASA satellite, known as Van Allen Probe A, is expected to re-enter Earth’s atmosphere tonight after spending nearly 14 years studying space around our planet. Scientists say the spacecraft will likely burn up during reentry, with minimal risk to people on Earth.
NASA estimates the satellite will reenter the atmosphere at around 7:45 p.m. Eastern Time, although the exact timing could vary by about 24 hours due to unpredictable atmospheric conditions.
What Is the Van Allen Probe Mission?
The Van Allen Probes mission launched in August 2012 with two spacecraft—Probe A and Probe B—designed to study the Van Allen radiation belts, regions of charged particles trapped by Earth’s magnetic field.
These radiation belts play a crucial role in protecting Earth by shielding the planet from cosmic radiation, solar storms, and solar wind that can affect satellites, astronauts, and even power grids.
Although the mission was originally planned to last two years, both probes exceeded expectations and continued collecting valuable scientific data for almost seven years before the mission ended in 2019.
Why the Satellite Is Returning Earlier Than Expected
Initially, scientists predicted that Van Allen Probe A would reenter Earth’s atmosphere around 2034. However, increased solar activity and intense space weather during the current solar cycle caused additional atmospheric drag on the spacecraft.
This extra drag gradually slowed the satellite’s orbit, pulling it closer to Earth sooner than expected.
Will the Satellite Be Dangerous?
NASA says most of the spacecraft will burn up as it travels through the atmosphere during reentry. However, some small fragments may survive and reach the ground.
The overall risk to humans is extremely low. NASA estimates the probability of someone being harmed by falling debris is about 1 in 4,200, or roughly 0.02%.
Because about 70% of Earth’s surface is covered by water, any remaining debris is far more likely to fall into the ocean rather than populated areas.
What Happens Next?
The U.S. Space Force is closely monitoring the spacecraft’s descent and will continue updating predictions about the reentry path and timing.
Meanwhile, the mission’s twin spacecraft, Van Allen Probe B, is expected to remain in orbit longer and may not reenter Earth’s atmosphere until 2030 or later.
Legacy of the Van Allen Probes
Despite its dramatic end, Van Allen Probe A leaves behind an important scientific legacy. Data from the mission helped scientists better understand how Earth’s radiation belts behave and how space weather can affect satellites, communication systems, and technology on Earth.
