Narrator: This is Science Today. Now that NASA's Curiosity rover has landed on Mars, the work begins for the scientists involved in the mission, including Dawn Sumner, a geology professor at the University of California, Davis.
Sumner: Looking at Mars is very exciting. I never expected to work on data from another planet. I like working with rocks and I like doing field work, going out and walking around. However, I've always enjoyed that thrill of exploration that planetary science provides. There's something really exciting about seeing something that no else has seen before.
Narrator: As co-investigator for NASA's Mars Science Laboratory team, Sumner's tasks include directing the rover via computer and shooting some of the first true color photographs ever taken of Mars.
Sumner: One of the main goals for the Mars Science Laboratory mission is to characterize ancient environment on Mars and understand whether or not it could have supported life.Narrator: For Science Today, I'm Larissa Branin.
