H. G. Wells wrote in his book, "War of the Worlds", about Martian invasion toward earth. He mentioned, "No one would have believed, in the last years of the nineteenth century that this world was being watched keenly and closely by intelligences greater than man's and yet as mortal as his own; that as men busied themselves about their various concerns they were scrutinized and studied, perhaps almost as narrowly as man with a microscope might scrutinize the transient creatures that swarm and multiply in a drop of water."

Since then it has now been about 100 years Wells based his well-known story of human's first contact with extraterrestrial life. Now, in the …show more content…

The famous meteorite to bare significant signs of life is the Allan Hills 84001 (ALH84001), classified as one of the meteorites thought to come from Mars. Due to the atmospheric data taken by the Viking Lander spacecraft sent to Mars in the 1970s. The data make it possible to know that gases trapped inside the rock is identical to the Martian atmosphere. "It is one of only 12 meteorites identified so far that match the unique Martian chemistry measured by the Viking spacecraft that landed on Mars in 1976" Scientist believed that the ALH84001 blasted off from the surface of Mars about 16 million years ago by a comet or asteroid. The rock orbited in the solar system for a few million years and finally reached Earth about 13, 000 years ago.

Investigation into the ALH84001 and the possibilities for containing remains of ancient Martian life was assigned to a team of NASA scientists. Dr. David McKay, Dr. Everett Gibson and Kathie Thomas-Kerpta of Lockhead Martin co-led the team with assistance from a Stanford team led by Professor of Chemistry Dr. Richard Zare. They investigated different features in ALH84001, trying to explain their origin and meaning and if these are evidence for life having once existed on …show more content…
