The theory holds that ALH84001 was blasted away from the surface of Mars by the impact of a meteor about 17 million years ago, [11] and fell on Earth about 13,000 years ago. [12] These dates were established by a variety of radiometric dating techniques, including samarium–neodymium (Sm–Nd), rubidium–strontium (Rb–Sr), potassium–argon ...

The Martian meteorite NWA 7034 (nicknamed "Black Beauty"), found in the Sahara desert during 2011, has ten times the water content of other Mars meteorites found on Earth. [2] The meteorite contains components as old as 4.42 ± 0.07 Ga (billion years), [25] and was heated during the Amazonian geologic period on Mars. [26]
