An international team of scientists has created a tiny chemistry lab for a rover that will drill beneath the Martian surface looking for signs of past or present life. The toaster oven-sized lab, called the Mars Organic Molecule Analyzer or MOMA, is a key instrument on the ExoMars Rover, a joint mission between the European Space Agency and the Russian space agency Roscosmos, with a significant contribution to MOMA from NASA. It will be launched toward the Red Planet in July 2020.
