the ammerican's space mission play


are you remembered the viking space probes of 1976-77 were looking for water and life on red plannet Mars. the result was there is no water on the plannet.Now the latest nasa mars study is revealing that there is a possibilty of water on the red plannet. new photographs of mars showed geologic changes that suggest water occasionally flows there-the most tantalising sign that mars is hospitable to life.
in the 70's the viking mission found no signs of life. but it was searching for earth like life,in which salt water is the internal liquid of living cells.given the cold dry conditions of mars that life could have evolved on mars with the key internal fluid consisting of a mix of water and Hydrogen peroxide.
the viking experiments of the 70's wouldn't have noticed alien hydrogen peroxide based life and in fact would have killed it by drowning and overheating the mocrobes.
a new nasa mars mission Phoenix is set for launch this summer, and one scientist involved said he is eager to test the new theory about life on mars.
