Scientists have found no indications so far of water in the first soil sample delivered to NASA's Mars Phoenix Lander, they announced on Monday.
After finally successfully delivering the sample to the Thermal and Evolved-Gas Analyzer (TEGA) on June 11, mission scientists carried out their first two analyses of the sample over the weekend. The sample was heated to 95F (35C) and then 350F (175C). No water was detected.
In the next few days, scientists will further heat the sample up, to a maximum of 1,800 F (1,000 C), to vaporize out minerals that might have chemically-bound water, carbon dioxide or sulfur dioxide.
