Special Regions on Mars are defined as environments able to host liquid water that meets certain temperature and water activity requirements that allow known terrestrial organisms to replicate, and therefore could be habitable.

How Water Fled Mars

Mars once had oceans but is now bone-dry, leaving many to wonder how the water was lost. University of Arizona researchers have discovered a surprisingly large amount of water in the upper atmosphere of Mars, where it is rapidly destroyed, explaining part of this Martian mystery.

Volcanic activity on Mars peaked during the Noachian and Hesperian periods but has continued since then in isolated locales. Elysium Planitia hosts numerous young, fissure-fed flood lavas with ages ranging from approximately 500 to 2.5 million years (Ma).

Mars Sample Return (MSR) is a highly complex and ambitious program of national importance. As noted by the MSR Independent Review Board (IRB), it is one of the most technically difficult and operationally demanding robotic space missions ever undertaken.

There's a long-standing question in planetary science about the origin of water on Earth, Mars and other large bodies such as the moon.

Humankind's next giant step may be onto Mars. But before those missions can begin, scientists need to make scores of breakthrough advances, including learning how to grow crops on the red planet.

The agency's newest rover will use the first ground-penetrating radar instrument on the Martian surface to help search for signs of past microbial life.

Data from Martian meteorites suggest the planet may have two hydrogen reservoirs beneath its surface, according to a recent study by NASA's Astromaterials Exploration Research and Science (ARES) Division and a team of planetary scientists. The study, published in the journal Nature Geoscience, could shed light on how Mars formed and evolved.

The detection of liquid water by the Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) at the base of the south polar layered deposits in Ultimi Scopuli has reinvigorated the debate about the origin and stability of liquid water under present-day Martian conditions.

ESA's Mars Express spacecraft has discovered several ponds of liquid water buried under the ice in the south polar region of Mars.

Could Life Exist Deep Underground On Mars?

Recent science missions and results are bringing the search for life closer to home, and scientists at the Center for Astrophysics | Harvard & Smithsonian (CfA) and the Florida Institute of Technology (FIT) may have figured out how to determine whether life is--or was--lurking deep beneath the surface of Mars, the Moon, and other rocky objects in the universe.

NASA's Mars 2020 Perseverance rover has a challenging road ahead: After having to make it through the harrowing entry, descent, and landing phase of the mission on Feb. 18, 2021, it will begin searching for traces of microscopic life from billions of years back.

In a little more than a decade, samples of rover-scooped Martian soil will rocket to Earth.

NASA should design missions to Mars for the purpose of generating "Aha!" discoveries to jolt scientists contemplating the molecular origins of life.

A new study from The University of Texas at Austin is helping scientists piece together the ancient climate of Mars by revealing how much rainfall and snowmelt filled its lake beds and river valleys 3.5 billion to 4 billion years ago.

The Red Planet has fascinated humans for millennia, especially for the last few centuries, and particularly during the Space Age. The nagging suspicion of extant Martian life is both fed by, and drives the many space missions to Mars and recent detections of large, seasonal volumes of atmospheric methane have re-fuelled the discussion.

Insights and technology gleaned from creating a carbon-measuring instrument for Earth climate studies is being leveraged to build another that would remotely profile, for the first time, water vapor up to nine miles above the Martian surface, along with wind speeds and minute particles suspended in the planet's atmosphere.

A large number of the valley networks scarring Mars's surface were carved by water melting beneath glacial ice, not by free-flowing rivers as previously thought, according to new UBC research published today in Nature Geoscience.

NASA Launched the Mars 2020 rover Perseverance today. As Perseverance departs it leaves a troubled world behind to explore a new one in search of life. At the Perseverance post-launch media event I asked NASA Administrator Jim Bridenstine and Science Mission Directorate Associate Administrator Thomas Zurbuchen about exploring a new world during such difficult times.
