The Mars Curiosity rover team announced today (June 7) finding organic matter – carbon-based compounds – in three billion year old mudstone sediments from Gale Crater. They also found seasonal changes in the amount of methane in the local atmosphere.

To find evidence of life on Mars, scientists from UC Davis and the U.S. Geological Survey are chasing clues in Mars-like environments on Earth.

The researchers hope to find rock patterns and textures that are uniquely linked to microscopic life such as bacteria and algae. “It’s challenging to prove that a mineral was made by a living organism,” said lead study author Amy Williams, an assistant professor at Towson University in Towson, Maryland. Williams led the research as a graduate student at UC Davis. Finding similar textures in Mars rocks could bolster confidence that microscopic shapes in Red Planet rocks were formed by living creatures.

In a universe with billions upon billions of planets, narrowing the search for extraterrestrial life is no mean feat. One approach seeks analogs of otherworldly conditions here on Earth, and characterizes the mineralogy, geochemistry and biology of these areas.
