A Martian meteorite is a rock that formed on Mars, was ejected from the planet by an impact event, and traversed interplanetary space before landing on Earth as a meteorite. As of September 2020, 277 meteorites had been classified as Martian, less than half a percent of the 72,000 meteorites that have been classified. [1]

ALH 84001 was found on the Allan Hills Far Western Icefield during the 1984–85 season, by Roberta Score, Lab Manager of the Antarctic Meteorite Laboratory at the Johnson Space Center. ALH84001 is thought to be one of the oldest Martian meteorites, proposed to have crystallized from molten rock 4.091 billion years ago. Chemical analysis suggests tha...
On August 6, 1996, a team of researchers led by NASA scientists including lead author David S. McKay announced that the meteorite may contain trace evidence of life from Mars. This was published as an article in Science a few days later. Under a scanning electron microscope, structures were visible that some scientists interpreted as fossils of bac...
The 2001 mystery-thriller novel Deception Point by Dan Brown, about a discovered meteorite that seems to prove the existence of extraterrestrial life, was inspired by ALH84001.

May 3, 2023 · A Martian meteorite, designated Northwest Africa (NWA) 7034 and nicknamed "Black Beauty," weighing approximately 11 ounces. Caltech researchers have now discovered that the shock pressure necessary to launch rocks from Mars' surface is less than previously believed.
Mar 6, 2014 · We show that the <5 million-year-old and 55-km-wide Mojave Crater on Mars is the ejection source for the meteorites classified as shergottites. Shergottites and this crater are linked by their coinciding meteorite ejection ages and the crater formation age and by mineralogical constraints.
