One of the biggest questions in planetary science is whether life ever arose on Mars, and NASA and the European Space Agency are sending a cutting-edge instrument to the red planet to find out. The Mars Organic Molecule Analyzer, or MOMA, is a sophisticated suite of technologies that squeezes a lab full of chemistry equipment into a package the size of a toaster. MOMA will travel to Mars aboard ESA's Rosalind Franklin rover (formerly ExoMars), where it will search for evidence of past or present life.

MOMA will not only search for organic molecules, which make up all life on Earth, it will also analyze their structure using its linear ion trap – the first use of this technology on Mars. Doing so will help scientists to determine whether the molecules could be of biological origin, a significant leap forward in the search for life beyond Earth.

MOMA's mass spectrometer subsystem and main electronics were built at NASA's Goddard Space Flight Center in Greenbelt, Maryland. The pulsed UV laser and high-temperature ovens were developed in Germany, and the gas chromatograph in France. The Rosalind Franklin rover is a component of ExoMars, the primary Mars exploration program of the European Space Agency.
