These images taken by the High-Resolution Stereo Camera (HRSC), onboard ESA’s Mars Express imaged the Noctis Labyrinthus region, the ‘labyrinth of the night’ on Mars.

Mars, like Earth, is a climate-fickle water planet. The main difference, of course, is that water on the frigid Red Planet is rarely liquid, preferring to spend almost all of its time traveling the world as a gas or churning up the surface as ice.

Scientists scouting potential landing sites for NASA's next Mars rover mission are using new data from a powerful mineral-mapping camera to narrow the site selection.

The High Resolution Stereo Camera (HRSC) on ESA’s Mars Express orbiter has obtained pictures of the Noachis Terra region on Mars, in particular, the striking Maunder crater.

A heat-sensitive camera designed at Arizona State University and flying on NASA's Mars Odyssey orbiter has led a team of Mars geologists to find seven small, deep holes on the flanks of Arsia Mons, a giant volcano on Mars. The holes may be openings, called skylights, in the ceilings of underground caves.

An MIT-led team of planetary scientists has found that the southern pole of Mars contains the largest deposit of frozen water in the inner solar system, outside of Earth.

Key components of a new approach to discover life on Mars were successfully launched into space Friday as part of a twelve-day, low-Earth orbit experiment to assess their survivability in the space radiation environment—a prelude future journeys to Mars.

Mars rover scientists have launched a new long-term study on the Martian atmosphere with the Alpha Particle X-ray Spectrometer, an instrument that was originally developed at the University of Chicago.

NASA clean rooms, where scientists and engineers assemble spacecraft, have joined hot springs, ice caves, and deep mines as unlikely places where scientists have discovered ultra-hardy organisms collectively known as ‘extremophiles’. Some species of bacteria uncovered in a recent NASA study have never been detected anywhere else.

Mars may also hold clues to climate change on earth, says Tufts' Sam Kounaves, co-investigator on Phoenix Mars Mission

IBM today announced that Power Architecture will make a return to outer space as NASA plans to launch the Phoenix Mars Lander, its most sophisticated probe to date. The lander will head to the polar north of Mars where it will dig into the frozen surface in search of the building blocks of life.

The High Resolution Stereo Camera (HRSC) on board ESA’s Mars Express obtained images of the Tyrrhena Terra region on Mars.
