Martian meteorite ALH84001
Stato: Guyana Anno: 1996 Notizie: In 1996 Guyana released a souvenir sheet depicting the Martian meteorite ALH84001 and the orbital path it took to reach Earth after being blasted off the surface of Mars by a giant impact. ALH84001 is a 1.9 kilogram Martian meteorite found in 1984 on the Allan Hills ice field in Antarctica. Some scientists suggest this meteorite contains possible traces of biological activity as evidenced by tubular structures that look like fossils of primitive organisms. A magnified image of one of these tubular structures appears above the image of the meteorite itself on the sheet. |

Stato: Madagascar Anno: 1998 Notizie: The second sheet displays within the main stamp area the 1.9 kilogram Martian meteorite ALH84001 found in 1984 on the Allan Hills ice field in Antarctica. Some scientists suggest this meteorite contains possible traces of biological activity. The background of the souvenir sheet portrays a giant impact which may represent one of those on Mars which blasted material from its surface into space. Some of this material eventually fell to Earth as meteorites, like ALH84001. The Martian meteorite is surrounded by two lunar meteorites and three terrestrial rocks. |
