Now we can know what a meteoroid – or space rock – hitting Mars sounds like. Thanks to the findings of NASA’s Insight lander. A seismometer was brought to the Red Planet to measure the “aftershocks”. The first of them was discovered by scientists last September, says the US space agency. It is said to be the very first time that such an impact of a space rock on another plant – has been recorded.
“My surroundings are calm and quiet, allowing me to pick up vibrations from deep within Mars,” reads a tweet posted from the InSight mission’s official handle. dramatic source: multiple meteoroids impacting miles away,” he adds.
Not only the sound, but also the image. The Reconnaissance Orbiter’s HiRISE (High Resolution Imaging Science Experiment) camera captured at least three craters on the Red Planet. The mission recorded details of the impacts of seismic waves from four space rocks that crashed into Mars in 2020 and 2021 and traveled between 85 and 290 kilometers from a region of Mars called Elysium Planitia, the US space agency said. .
The first of the four confirmed meteoroids the term used for space rocks before they hit the ground made the most dramatic entry: On September 5, 2021, it entered the Martian atmosphere and exploded into at least three fragments, each leaving a crater in its wake. ,” says the space agency. Here’s another question on the minds of researchers – why haven’t they noticed other meteoroid impacts on Mars?
“The Red Planet is next to the main asteroid belt of the Solar System, which provides enough space rocks to scratch the surface of the planet. “Because the Martian atmosphere is only 1 percent thicker than Earth’s, more meteoroids pass through it without breaking up,” NASA said in a statement.
“The InSight team suspects that other impacts may have been masked by wind noise or seasonal changes in the atmosphere. But now that the signature seismic signature of a Martian impact has been discovered, scientists expect to find more shelters during InSight’s nearly four years.” data,” he emphasizes.
