About the data


The data from this challenge comes from GCMS commercial instruments at the Planetary Environments Laboratory at Goddard Space Flight Center in Greenbelt, Maryland. Scientists from the Sample Analysis at Mars (SAM) team analyze rock and soil samples using these Earth-based instruments so that they can compare the measured data with those for unknown Martian samples sent back by Curiosity.

About the NASA team


The Sciences and Exploration Directorate is the largest Earth and space science research organization in the world. Its scientists advance understanding of the Earth and its life-sustaining environment, the Sun, the solar system, and the wider universe beyond. The Directorate is part of Goddard Space Flight Center (GSFC) in Greenbelt, Maryland.

Sample Analysis at Mars (SAM) is an instrument suite on the Curiosity rover, part of NASA's Mars Science Laboratory mission that was launched in November 2011 and landed on Mars in August 2012. SAM has several capabilities and operating modes that can be used for chemical analysis and identification of samples.

The SAM team is based at NASA's Goddard Space Flight Center in Greenbelt, Maryland with additional team members from other institutions across the United States and internationally. The SAM team developed the instrument suite that is now onboard Curiosity on Mars and is responsible for its continued operations. Here on Earth, the SAM team's scientists analyze the data from Martian samples collected by Curiosity and reproduce those measurements with controlled samples in their labs.
