ALH84001. On December 27, 1984, the NASA geologists during an expedition in Antarctica found a meteorite greenish hue. Scientists have suggested that it was a fragment of the asteroid. ALH84001 was kept until 90-ies without the exact characteristics of this meteorite. In the early 90-ies after his detailed study under the microscope, it turned out that it was a rock from Mars. The characteristics of this stone coincided with another meteorite that was found in 1979. The electron microscope has recorded a possible organic structure with something resembling a worm.

In the late 90-ies after studying the meteorite ALH84001 international community's final agreement, that this was indeed the organic structure was not achieved. The articles were put forward in favor of protection of this hypothesis and also against it. In April 2010, scientists were able to ascertain more accurately the age of the meteorite ALH84001. Now consider that he 4bn 100 million years.

This meteorite is also interesting because it belongs to a time when Mars had liquid water and the atmosphere. It is considered initially that the surface of Mars (ALH84001) was damaged by a meteorite and then, after a long period of time, ALH84001 broke away from Mars by dropping another rock on the planet. Then the piece of the Martian surface was in space for 16 million years. About 13 thousand years ago, ALH84001 fell to the Earth, where it was found in 1984.
