Phoenix Results Point to Climate Cycles
July 5, 2009 / Posted by: Aaron Gronstal
The first major peer-reviewed reports on the finding of NASA’s Phoenix Mars Mission have been published in the journal Science. The reports show how favorable chemistry and episodes of liquid water could have made the Phoenix landing site habitable for microbes in Mars’ past. In fact, it is possible that the site could become habitable again in Mars’ future according to Phoenix Principal Investigator, Peter Smith (ASU).Source: [astrobio.net]
