687 DAYS OF EXPLORATION

摘要

During its primary mission, Curiosity will record weather patterns, analyze air composition, and test rocks for amino acids, methane and other organic compounds that could indicate the possibility of Martian life now or in the past. It will also face freezing temperatures, high winds and other hazards, Including sand pits and cliffs. To prepare for such demands, engineers built Curiosity as a new kind of rover-hardier, more autonomous and loaded with more scientific instruments than any craft before it.
