Allan Hills 77005 (also known as Allan Hills A77005, ALHA77005, ALH77005 and ALH-77005[1][2]) is a Martian meteorite that was found in the Allan Hills of Antarctica in 1977 by a Japanese National Institute of Polar Research mission team[3] and ANSMET.[4] Like other members of the group of SNCs (shergottite, nakhlite, chassignite), ALH-77005 is thought to be from Mars.[5]

Description

On discovery, the mass of ALH-77005 was Шаблон:Convert. Initial geological examination determined that the meteorite was composed of ~55% olivine, ~35% pyroxene, ~8% maskelynite and ~2% opaques.[6]

In March 2019, researchers reported the possibility of biosignatures in this Martian meteorite based on its microtexture and morphology as detected with optical microscopy and FTIR-ATR microscopy, and on the detection of mineralized organic compounds,[2][3][7] suggesting that microbial life could have existed on the planet Mars.[3] More broadly, and as a result of their studies, the researchers suggest Solar System materials should be carefully studied to determine whether there may be signs of microbial forms within other space rocks as well.[3]
