A team from NASA's Goddard Space Flight Center gathered last week to bid farewell to a mass spectrometer as it began its journey to the red planet via an assembly plant in Italy.

The instrument is a key component of a toaster oven-sized lab, called the Mars Organic Molecule Analyzer (MOMA), which will detect evidence of complex organic compounds in samples retrieved from deep below the surface of Mars.
