Curiosity has discovered new "tough" organic molecules in three-billion-year-old sedimentary rocks on Mars, increasing the chances that the record of habitability and potential life could have been preserved on the Red Planet, despite extremely harsh conditions on the surface that can easily break down organic molecules.

Iron-rich rocks near ancient lake sites on Mars could hold vital clues that show life once existed there, research suggests.

An international team of scientists has created a tiny chemistry lab for a rover that will drill beneath the Martian surface looking for signs of past or present life.

By studying a stream on the UK coast, experts have calculated how much organic matter we might find on Mars, and where to look.

In this Letter, we make use of sophisticated 3D numerical simulations to assess the extent of atmospheric ion and photochemical losses from Mars over time.

The climate of early Mars is a subject of debate. While it has been thought that Mars had a warm and wet climate, like Earth, other researchers suggested early Mars might have been largely glaciated.

Researchers at the University of Colorado Boulder have discovered microbes living in a toxic volcanic lake that may rank as one of the harshest environments on Earth.

A University of Cincinnati geology student is helping NASA determine whether life existed on other planets.

Keith's Note: NASA recently posted an image taken by the Mars Hand Lens Imager (MAHLI) aboard NASA's Mars rover Curiosity. A reader from Australia contacted me to point out some curious structures within the rock featured in that image.

In 2013, the European Space Agency and Roscosmos -- the Russian governmental body responsible for space research -- agreed to cooperate on ExoMars, the first joint interplanetary mission between ESA and Russia.
