Scientists hope the technology could help future Mars-goers produce breathable air and rocket fuel for return trips.
The unmanned spacecraft made it to Mars on Thursday after a long, seven-month trip.
The NASA craft lands this afternoon and will immediately set to searching for evidence of water.
"Organic molecules are those that contain chains and rings of carbon atoms linked together—like those used by life," said researcher Atsuko Kobayashi.
The rover will search for signs of past microbial life on Mars, while also investigating the planet's climate and geology.
The 'abiotic' methane may hold clues about its presence elsewhere in the solar system, researchers say.
Warmer conditions on Ancient Mars increase the possibility that life developed there, according to researchers.
Harvard-led team say a thin layer of silica aerogel could insulate the planet's surface.
The discovery could have significant implications in the search for signs of past life on the Red Planet.
A new study suggests that the Red Planet could have supported subsurface microbes.
Is the briny sludge teeming with tiny organisms?
Scientists found that Mars's crust formed much earlier than previously thought.
The rover has discovered ancient organic material that may be biological in origin, although this has not yet been proven.
These rocks formed at the bottom of ancient lake beds between three and four billion years ago, when the Martian surface was abundant in water and its climate was warmer.
The ExoMars Rover will drill more than six feet underground to search for organic material.
Laguna Caliente in Costa Rica is one of the harshest environments on Earth for life.
They might be a ready-made water source for explorers.
It's the very latest in spa treatments for planets that just want to be pampered.
NASA already explained the "concretion" phenomenon when a similar image made the rounds in 2014.
Scientists at the NASA Goddard Space Flight Center called the flight a "breathtaking ride."
U.S. Representative Dana Rohrabacher questioned space experts about life on the planet.
Analysis of rocks from the Gale crater show climate change on the Red Planet over billions of years.
