Gale’s winds sculpted the Mt. Sharp mound as they built it

The major reason for sending the Mars Science Laboratory rover Curiosity to Gale Crater is the five-kilometer (three-mile) high layered mound, dubbed Mt. Sharp, that looms at the crater’s center. The lowest layers have been altered by water and perhaps … Continue reading

Gale Crater’s Lake District

Mars rover Curiosity landed on, or just beyond, the far end of an alluvial fan — rocks, gravel, and sand washed down by the Peace River from the north rim of Gale Crater. The rover has driven for 200 sols … Continue reading

Developing a stratigraphic column for Gale Crater’s floor

After more than 100 sols (Martian days) in Gale Crater, NASA’s Curiosity rover has driven some 500 meters (1,600 feet), traversing several rock units. A sketch of the crater floor’s geological history is emerging. On its half-kilometer drive from its … Continue reading

Blowing sand and moving dunes in Gale Crater

Curiosity, NASA’s Mars Science Laboratory rover, is exploring the floor of Gale Crater. Its main science target, however, is the giant stack of water-altered sediments that make up Mount Sharp, Gale Crater’s central mound. But to reach the mound, the … Continue reading

Hardened arteries in Nili and Nilo

Water seeping through conduits and cracks in the deep subsurface rocks of Nilosyrtis and Nili Fossae left behind minerals, like hard-water deposits that collect in the plumbing of your house. (Or cholesterol in your arteries.) Then as the softer rocks … Continue reading

Mars’ ancient climate had a “wet-pass” filter

Volcanic eruptions — and the rocks they produce — dominate the surface of the Red Planet. Mars also shows evidence for activity by liquid water — sediments, channels, and valley networks — through much of its history. While volcanos can … Continue reading

When Gale was young

With Mars rover Curiosity safely down on Mars, scientists are set to explore the geology and history of Gale Crater, searching for evidence of habitable environments, ancient or modern. Gale Crater has attracted much study since it became a candidate … Continue reading

Duck & cover: good advice for Mars organics

Everyone knows Mars has a terrible environment: temperatures are bitter cold most of the time, there’s almost no air pressure, and solar ultraviolet light scours the surface unhindered. Actually, it’s even worse. Alexander Pavlov (NASA Goddard Space Flight Center) and … Continue reading

“Blueberries” could date when Meridiani rocks were last wet

The relative amount of three chemical elements contained in Martian “blueberries” might offer scientists a way to date when these spherules were last inundated with water, according to recent research. Rich in the iron mineral hematite, blueberries are small concretions, … Continue reading

Gale Crater’s mound: part of the Medusae Fossae Formation?

The Medusae Fossae Formation (MFF) is a thick deposit of soft materials that erodes easily by wind. The formation spreads in several large patches between the volcanic provinces of Elysium and Tharsis. In addition, outliers extend farther afield, with some … Continue reading
