Researchers have found that even a slight collision between an asteroid and Mars can propel rocks into space and fly back to Earth..
In a groundbreaking study, scientists from the California Institute of Technology (Caltech) and the Jet Propulsion Laboratory (JPL) discovered the travels of towards the earth. By testing common assumptions and performing complex simulations in the lab, the team discovered that the force needed to propel Martian rock through space was less than expected. This discovery has important implications for understanding the geological history of the Red Planet and the abundance of Martian meteorites on Earth.

Of the thousands of meteorites found on Earth, There are about 188 meteorites confirmed to come from Mars. During its violent history, asteroids struck Mars with such force that debris blasted through space and drifted through space, eventually falling through Earth’s atmosphere and heading toward the surface. Astronomers once thought it was a complicated process, but only the most powerful collisions can send rocks from Mars into space. However, new research published May 3 in the journal Science Advance shows that the collision force required is much lower, meaning there could be more Martian debris drifting through space and flying towards Earth. .
To unravel the mystery surrounding the Martian meteorite, scientists are using advanced lab simulations to reconstruct the conditions of the impacts. Leaving rock mass containing plagioclasea common Martian mineral, exposed to the intense pressure created by the explosives, the team was able to observe and analyze the changes that occur during the process.
Using lab simulations, the researchers found that the force needed to blast Martian rock into space was significantly lower than originally thought. Previous experiments have shown that plagioclase transforms into a glass-like compound called maskelynite at a pressure of 30 gigapascals (GPa). However, the new study shows that the transformation occurs at around 20 Ga, which complicates understanding of the launch dynamics.
According to the study results, even a moderate impact on Mars can cause rocks to be thrown into space, increasing the chances of Martian meteorites reaching Earth. This opens up many exciting possibilities for detecting more Martian meteorites and collecting valuable data on the Red Planet’s geological activity.
The results of the study have important implications for understanding the geological history of Mars. The meteorite provides unique information about Mars’ past such as formation, volcanic activity and ability to support life. By characterizing the forces acting on Martian rocks, scientists can refine their study of meteorites and find impact craters where they were born on Mars.
