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.

The presence of water on Mars has been theorized for centuries. Early telescopes revealed ice caps, and early astronomers noted channels that were hypothesized to be natural rivers or creature-created canals.

The Mars Science Laboratory (MSL) Rover Environmental Monitoring Station (REMS) has now made continuous in-situ meteorological measurements for several martian years at Gale crater, Mars.

Mars' organic carbon may have originated from a series of electrochemical reactions between briny liquids and volcanic minerals, according to new analyses of three Martian meteorites from a team led by Carnegie's Andrew Steele published in Science Advances.

The climate of early Mars remains a topic of intense debate. Ancient terrains preserve landscapes consistent with stream channels, lake basins, and possibly even oceans, and thus the presence of liquid water flowing on the Martian surface 4 billion years ago.

We review the abundance and diversity of terrestrial rock hosted life, the environments it inhabits, the evolution of its metabolisms, and its fossil biomarkers to provide guidance in the search for the biomarkers of rock hosted life on Mars.

A new study shows evidence that ancient Mars probably had an ample supply of chemical energy for microbes to thrive underground.

Currently, Mars is the celestial object with the biggest quantity of devices made by mankind.
