NASA's dart mission: Potential for first human-caused meteor showers
NASA may have inadvertently created the first human-caused meteor shower. New research reveals surprising facts and opens new avenues in studying meteorites and the interactions of celestial bodies with planets.

The DART mission, conducted by NASA in 2022, heralded a new era of space exploration by enabling the displacement of a celestial body for the first time. The impact on the asteroid Dimorphos altered its orbit and may have triggered effects that are only now being studied. New simulations indicate that asteroid fragments could reach Mars and Earth, raising the possibility of observing meteorites with unusual origins.
The first case of celestial body displacement
In 2022, NASA executed the groundbreaking DART mission, potentially revolutionising our understanding of the movement of celestial bodies. The mission involved striking the asteroid Dimorphos, a moon of the asteroid Didymos, to change its orbit. This marked the first time humanity successfully moved a celestial body.
How was it done? DART, a probe the size of a car, crashed into the asteroid at full speed, approximately 150 metres in diameter. The collision released enormous debris and dust that spread far beyond the asteroid system. DART was accompanied by a small CubeSat satellite named LICIACube, which closely observed the collision.
What was discovered? New simulations based on LICIACube data indicate that Dimorphos fragments could reach Earth and Mars. Calculations suggest that some particles might travel to Mars in about 13 years. This discovery opens up the possibility of future meteor showers from Dimorphos on Mars and potentially on Earth.
A new breakthrough in studying Mars's surface?
Recent simulations conducted by a research team based on DART mission data and LICIACube observations reveal potentially groundbreaking possibilities for studying Mars's surface. These simulations showed that fragments of the asteroid Dimorphos, ejected during the collision, could reach Mars in about 13 years. This finding is fascinating for scientists studying the Red Planet.
What are the implications for Mars? Firstly, meteorites from Dimorphos could provide valuable information about the composition and properties of celestial bodies, which might differ from those observed on Earth. If research missions on Mars record these meteorites, they could offer new data on the impact of cosmic bodies on the planet's surface and help to understand its geological history better.
What could happen in the future? If predictions hold true, future missions to Mars could encounter meteorites from Dimorphos, which could be observed and analysed by research instruments. This could significantly impact our understanding of interactions between celestial bodies and Mars's surface and provide new information about potential resources and conditions on the planet.
