SAM uses a suite of three analytical tools to study chemistry relevant to life. One key job is looking for carbon-based compounds that on Earth are building blocks of life. SAM will examine gases from the Martian atmosphere and gases that ovens and solvents pull from powered rock and soil samples. Curiosity's robotic arm will deliver the powdered samples to one of two inlet funnels on the rover deck. Atmospheric samples enter through filtered inlet ports on the side of the rover.
