The processes behind the release and consumption of methane on Mars have been discussed since methane was measured for the first time for approx. 15 years ago.

One of the great attractions of the island of Santorini, in Greece, lies in its spectacular volcanic landscape, which also contains places similar to those of Mars. A team of European and U.S. scientists has discovered it after analysing basaltic rocks collected in one of its coves.

A new international study led by Western University shows that Mars' first 'real chance' at developing life started very early, 4.48 billion years ago, when giant, life-inhibiting meteorites stopped striking the red planet.

This week, NASA's Curiosity Mars rover found a surprising result: the largest amount of methane ever measured during the mission -- about 21 parts per billion units by volume (ppbv).

A rover scanning the surface of Mars for evidence of life might want to check for rocks that look like pasta, researchers report in the journal Astrobiology.

Collisional charging is one potential initial step in generating lightning. In this work, we study the charging of colliding monodisperse, spherical basalt grains depending on ambient pressure.

Newly discovered layers of ice buried a mile beneath Mars' north pole are the remnants of ancient polar ice sheets and could be one of the largest water reservoirs on the planet, according to scientists at The University of Texas at Austin and the University of Arizona.

Regolith on Mars exchanges water with the atmosphere on a diurnal basis and this process causes significant variation in the abundance of water vapor at the surface.

A well-preserved, ancient delta deposit, in combination with ample exposures of carbonate rich materials, make Jezero Crater in Nili Fossae a compelling astrobiological site.

A Martian water-ice cloud climatology has been extracted from OMEGA data covering 7 Martian years (MY 26-32).

Bacterial resistance to antibiotics is one of humankind's major long-term health challenges. Now research into helping humans live on Mars could help address this looming problem.

Resarchers from Hungary have discovered embedded organic material in a Martian meteorite found in the late 1970s.

A reanalysis of data collected by ESA's Mars Express during the first 20 months of NASA's Curiosity mission found one case of correlated methane detection, the first time an in-situ measurement has been independently confirmed from orbit.

In mid-2018, researchers supported by the Italian Space Agency detected the presence of a deep-water lake on Mars under its south polar ice caps.

An international team of researchers, which includes scientists from McMaster's School of Geography & Earth Sciences, NASA, and others, is tackling one of the biggest problems of space travel to Mars: what happens when we get there?

A robotic rover deployed in the most Mars-like environment on Earth, the Atacama Desert in Chile, has successfully recovered subsurface soil samples during a trial mission to find signs of life.

Mars Express has revealed the first geological evidence of a system of ancient interconnected lakes that once lay deep beneath the Red Planet's surface, five of which may contain minerals crucial to life.

Geologic Constraints on Early Mars Climate

Early Mars climate research has well-defined goals (Mars Exploration Program Analysis Group 2018). Achieving these goals requires geologists and climate modelers to coordinate.

Whether extant life exists in the martian subsurface is an open question.

Mars and Earth are like two siblings who have grown apart. There was a time when their resemblance was uncanny: Both were warm, wet and shrouded in thick atmospheres. But 3 or 4 billion years ago, these two worlds took different paths.
