NASA’s Curiosity rover has detected what could be a chemical relic of long-ago life on Mars: long-chain organic molecules likely derived from fatty acids, a common building block of cell membranes on Earth. DEEPS Professor Jack Mustard commented on these exciting findings, suggesting that Curiosity’s successor, Perseverance, will likely find similar molecules.

NASA has announced a new strategy review team, including DEEPS Professor Jack Mustard, to assess potential architecture adjustments for the agency’s Mars Sample Return Program. The program aims to bring back scientifically selected samples from Mars, and is a key step in NASA’s quest to better understand our solar system and help answer whether we are alone in the universe.

Professor Jack Mustard spoke with Scientific American about the Mars Sample Return program and NASA's recent update. “There are aspects of solar system evolution that can only be done through the return of samples [from Mars]."

DEEPS Professor John Mustard recently shared his opinion with Nature about NASA's new considerations for the Perseverance rover's mission, saying the rocks currently on board are “great, but they’re not sufficient to be the transformative samples that we want them to be.”
