The Phoenix Mars Mission aimed to study the habitability of Mars' arctic plains. Key goals included determining if life ever arose on Mars, characterizing the planet's climate and geology, and preparing for human exploration. Phoenix landed near the Martian north pole in 2008, where it used instruments on a robotic arm to analyze soil and ice samples. The mission successfully confirmed the presence of water ice on Mars and gathered weather data to understand Mars' climate, helping to advance understanding of the planet's potential for life and resources for future human missions.
