MARS (continued)

Another reason for scientists to expect life on Mars had to do with the apparent seasonal color changes on the planet's surface. This phenomenon led to speculation that conditions might support a bloom of Martian vegetation during the warmer months and cause plant life to become dormant during colder periods.

Samples taken from Vikings Lander I and 2, in 1976 were thought to have primitive microbial fossils, but many scientists feel that a mineral deposit is a better explanation. Earthlings desperately want to have Martians as our neighbors, so myths will continue.

 


Center of Valles Marineris is 4000 km long.
