NASA discovers largest fresh meteoroid impact on Mars in 16 years

Last year, on December 24, NASA’s InSight lander detected a magnitude 4 marsquake, which initially didn’t appear to be anything out of the ordinary. Only later did NASA learn that this particular marsquake was quite remarkable, caused by one of the largest meteoroid strikes that NASA has ever seen on Mars.

Unlike Earth, Mars has a relatively thin atmosphere. This makes the planet far more vulnerable to meteorite strikes. In newly released audio from NASA, the Insight lander picks up the vibrations and sounds of four meteoroids striking the planet’s surface.

Last week NASA announced the Martian InSight lander’s mission would conclude by the end of this year due to low power. One of the first steps to get the lander ready for that will be placing the arm into its final resting position. So today, NASA shared InSight’s final selfie using the arm’s camera.

NASA announced on May 17 that it expects the InSight lander mission to end this year. While it hasn’t gotten as much attention as the Perseverance rover, InSight has made some remarkable discoveries during its lifetime.

NASA InSight’s mole probe sadly fails to dig into the Martian surface

NASA’s InSight lander was launched back in 2018 from Vandenberg Air Force Base on an Atlas V rocket and was the first interplanetary mission from California. The lander made it safely to the surface of Mars on November 26, carrying new experiments to learn more about Mars subsurface science.

The two big experiments that took the ride to the Red Planet were a seismometer and “self-hammering nail” to study the thermal properties below the surface of Mars nicknamed “the mole”. The mole ran into problems almost right away after it was lifted off the top of the lander and placed on the ground in late 2019.

NASA’s InSight Mars lander touched down one year ago after a six month journey from Earth to the Red Planet. Today six papers were published with a year of science learned through year one of the lander mission.

A new understanding of Mars is beginning to emerge, thanks to the first year of NASA’s InSight lander mission. Findings described in a set of six papers published today reveal a planet alive with quakes, dust devils and strange magnetic pulses.

Five of the papers were published in Nature. An additional paper in Nature Geoscience details the InSight spacecraft’s landing site, a shallow crater nicknamed “Homestead hollow” in a region called Elysium Planitia.

InSight is equipped to detect Mars quakes, wind speed, air pressure, and more.
