Unpredicted Behavior of NASA Spacecraft’s Collided Asteroid Intrigues High School Students
Introduction:
The asteroid Dimorphos has shown unexpected behavior after being struck by a NASA rocket. Recent observations indicate that Dimorphos may be tumbling in its orbit and continuously slowing down, contrary to predictions. California high school teacher Jonathan Swift and his students first detected these changes, and further investigations suggest that a swarm of space rocks could be responsible for the slowdown. The DART team plans to release a report on these findings, while the European Space Agency’s Hera spacecraft will investigate the crash site in 2026.

DART Mission: Asteroid Dimorphos Behavior Surprises Scientists
A NASA Experiment Gone Astray
In an unexpected twist, data suggests that the asteroid Dimorphos is behaving in ways that scientists didn’t anticipate after being struck by a NASA rocket last year. Dimorphos, which measures approximately 580 feet wide, was intentionally crashed into by a spaceship as part of NASA’s Double Asteroid Redirection Test (DART) mission on September 26, 2022. Recent observations reveal that Dimorphos is now tumbling in its usual steady orbit around its parent asteroid, Didymos. This finding contradicts previous predictions made by NASA. Dimorphos also appears to be gradually slowing down in its orbit for more than a month after the rocket impact, which is another surprising revelation.
Sharp-Eyed High School Teacher’s Discovery
The unexpected changes in Dimorphos’ behavior were initially detected by Jonathan Swift, a high school teacher in California, and his students. Using their school’s 2.3-foot telescope, they observed the asteroid shortly after the DART impact. Weeks later, NASA reported that Dimorphos had slowed in its orbit around Didymos by approximately 33 minutes. However, when Swift and his students observed Dimorphos again a month after the impact, they noticed that the asteroid had actually slowed down by an additional minute. This suggests that Dimorphos had been continuously slowing down since the collision, a finding that unsettled the researchers.
Confirmation of the Unexpected Changes
Swift presented his class’s findings at the American Astronomical Society conference in June. Subsequently, the DART team confirmed that Dimorphos did, in fact, continue to slow in its orbit for up to a month after the impact. However, their calculations indicated a slow down of 15 seconds rather than an entire minute. The slowdown eventually reached a plateau one month after the DART collision.
Unraveling the Mystery
The question remains: what caused Dimorphos to gradually decelerate over the span of a month before reaching equilibrium? Recent observations of the asteroid have revealed a vast field of boulders. These boulders are likely debris that was dislodged from Dimorphos’ surface during the impact. It is possible that some of the larger boulders fell back onto Dimorphos within the first month, causing a more significant slowdown in its orbit than initially anticipated. Harrison Agrusa, a member of the DART team, suggested this hypothesis.
Future Investigations
The DART team plans to release its own report on these unexpected findings in the coming weeks, but a complete understanding may have to wait until 2026. The European Space Agency’s Hera spacecraft is scheduled to arrive at Dimorphos in 2026 to investigate the crash site up close. This in-depth examination is expected to provide further insight into the behavior of Dimorphos and the consequences of the DART mission.
Conclusion
The surprising behavior of Dimorphos following the collision with the NASA rocket has sparked intrigue among scientists. The ongoing studies and upcoming investigations promise to shed more light on the cosmic impact and the dynamics of asteroids. Dimorphos continues to unveil new mysteries, keeping scientists on their toes as they strive to expand our knowledge of the universe.
