Mars meteorite: Largest impact ever recorded unearths chunks of ice
Telegraph, 28 Oct 2022
A “once in a generation” martian meteorite impact is the biggest ever recorded in the Solar System.
A magnitude 4 marsquake was recorded on Christmas Eve last year and data from the NASA InSight rover captured the vibrations more than 2,200 miles away.
A bus-sized rock up to 39ft-wide landed in an equatorial region of the red planet known as the Amazonis Planitia and created a 500-ft wide crater which was 70 feet deep. Chunks of ice and other ejecta were thrown as far as 23 miles away, scientists found.
Larger meteorites have crashed into planets but none have been directly studied by scientists.
The true origin of this so-called "marsquake" was only confirmed when the Mars Reconnaissance Orbiter (MRO) was able to take a picture of the newly formed crater created by the hit when it flew over the impact site less than 24 hours later.
The image is impressive, showing blocks of ice that were spewed up onto the planet's surface around the 492-foot wide and 70-foot deep hole.
