SCIENTISTS BEHIND THE MARS ROVER – S.A.S. SPECTROSCOPISTS

Hundreds of engineers and scientists with a wide diversity of expertise work together in hopes of discovering more information about Mars and unlocking any secrets that may be hidden beneath its surface. Challenges in design, building and implementation of the instruments must be overcome to ensure that every part of the equipment functions the way they should in a vastly different and hostile environment. Once the data returns, scientists must work under strict time constraints to decipher and comprehend what they have found to determine their next move.

Featured here are some scientists involved with the spectrometers on the Perseverance rover, ranging in expertise and career levels. Learn about their professional paths, their roles on the Mars mission, their preferences when it comes to food and movies, and much more.
