The lab, called the Mars Organic Molecule Analyzer or MOMA, is a key instrument on the ExoMars Rover which is scheduled to launch to Mars in July, 2020 from the Baikonur spaceport in Kazakhstan, NASA said in a statement.
ExoMars Rover is a joint mission between the European Space Agency and the Russian space agency Roscosmos, with a significant contribution to MOMA from NASA.
"The ExoMars Rover's two-meter deep drill will provide MOMA with unique samples that may contain complex organic compounds preserved from an ancient era, when life might have gotten started on Mars," said MOMA Project Scientist Will Brinckerhoff of NASA's Goddard Space Flight Center in Greenbelt, Maryland.
Although the surface of Mars is inhospitable to known forms of life today, there is evidence that in the distant past, the Martian climate allowed the presence of liquid water -- an essential ingredient for life -- at the surface.
This evidence includes features that resemble dry riverbeds and mineral deposits that only form in the presence of liquid water.
NASA has sent rovers to Mars - such as the Opportunity and Curiosity - that have found additional signs of past habitable environments.
The ExoMars rover will be the first to explore deep beneath the surface, with a drill capable of taking samples from as deep as two metres (over six feet).
The MOMA instrument will be capable of detecting a wide variety of organic molecules.
Organic compounds are commonly associated with life, although they can be created by non-biological processes as well. They contain carbon and hydrogen, and can include oxygen, nitrogen, and other elements.
To find these molecules on Mars, the MOMA team had to take instruments that would normally occupy a couple of workbenches in a chemistry lab and shrink them down to roughly the size of a toaster oven so they would be practical to install on a rover.
While the instrument is complex, MOMA is built around a single, very small mass spectrometer that separates charged atoms and molecules by mass.
The basic process for finding Martian organic compounds can be boiled down to two steps -- separate organic molecules from the Martian rocks and sediments and give them an electric charge so they can be detected and identified by the mass spectrometer, NASA said.
