Elysium

Mars' mantle may be more complicated than previously thought. In a new study published today in the Nature-affiliated journal Scientific Reports, researchers at LSU document geochemical changes over time in the lava flows of Elysium, a major martian volcanic province.

Mars surface

At an international workshop this week about where NASA's next Mars rover should land, most of the information comes from a prolific spacecraft that's been orbiting Mars since 2006.

Examining The Paradox of Ancient Mars

Examining The Paradox of Ancient Mars

Mars scientists are wrestling with a problem. Ample evidence says ancient Mars was sometimes wet, with water flowing and pooling on the planet's surface.


Martian Dunes in Northern Summer

Martian Dunes in Northern Summer

This dune field formed near the base of the North Polar cap. Dunes require a source of loose particulate material to form. The source of the northern dune fields around the polar cap may be from the layers of dusty ice that are eroded by strong polar winds.


New View Of Mars' North Pole

New View Of Mars' North Pole

The mosaic was generated from 32 individual orbit 'strips' captured between 2004 and 2010, and covers an area of around a million square kilometres.


How Gas Carves Channels On Mars

How Gas Carves Channels On Mars

A layer of dry ice covers the South Polar layered deposits every winter. In the spring, gas created from heating of the dry ice escapes through ruptures in the overlying seasonal ice, entraining material from the ground below.


Similar-Looking Ridges on Mars Have Diverse Origins

Similar-Looking Ridges on Mars Have Diverse Origins

Thin, blade-like walls, some as tall as a 16-story building, dominate a previously undocumented network of intersecting ridges on Mars, found in images from NASA's Mars Reconnaissance Orbiter.


Curiosity Examines Possible Mud Cracks on Mars

Curiosity Examines Possible Mud Cracks on Mars

Scientists used NASA's Curiosity Mars rover in recent weeks to examine slabs of rock cross-hatched with shallow ridges that likely originated as cracks in drying mud.


Well-Preserved Impact Ejecta on Mars

Well-Preserved Impact Ejecta on Mars

This image of a well-preserved unnamed elliptical crater in Terra Sabaea, is illustrative of the complexity of ejecta deposits forming as a by-product of the impact process that shapes much of the surface of Mars.


Earth and Its Moon as Seen From Mars

Earth and Its Moon as Seen From Mars

From the most powerful telescope orbiting Mars comes a new view of Earth and its moon, showing continent-size detail on the planet and the relative size of the moon.


Growth of a Martian Trough Network

Growth of a Martian Trough Network

Erosion-carved troughs that grow and branch during multiple Martian years may be infant versions of larger features known as Martian "spiders," which are radially patterned channels found only in the south polar region of Mars.


First Detection of Boron on the Surface of Mars

First Detection of Boron on the Surface of Mars Video in Story

Boron has been identified for the first time on the surface of Mars, indicating the potential for long-term habitable groundwater in the ancient past.


ExoMars Trace Gas Orbiter Image of Phobos

The ExoMars Trace Gas Orbiter has imaged the martian moon Phobos as part of a second set of test science measurements made since it arrived at the Red Planet on 19 October.


CaSSIS Sends First Images From Mars Orbit

CaSSIS Sends First Images From Mars Orbit Video in Story

The Mars Camera, CaSSIS on the ExoMars Trace Gas Orbiter captured its first high resolution images of the Red Planet last week. The Bernese camera worked almost perfectly and has provided spectacular views of the surface.


Adamas Labyrinthus on Mars

Adamas Labyrinthus on Mars

This labyrinth-like system of troughs and plateaus was imaged by ESA's Mars Express on 21 June 2016.


IMU Issues May Have Led To ExoMars Schiaparelli Crash

IMU Issues May Have Led To ExoMars Schiaparelli Crash

Good progress has been made in investigating the ExoMars Schiaparelli anomaly of 19 October. A large volume of data recovered from the Mars lander shows that the atmospheric entry and associated braking occurred exactly as expected.


Mars Ice Deposit Holds as Much Water as Lake Superior

Mars Ice Deposit Holds as Much Water as Lake Superior

Frozen beneath a region of cracked and pitted plains on Mars lies about as much water as what's in Lake Superior, largest of the Great Lakes, researchers using NASA's Mars Reconnaissance Orbiter have determined.


Color Imagery of Schiaparelli Crash Site

Color Imagery of Schiaparelli Crash Site

New high-resolution images taken by a NASA orbiter show parts of the ExoMars Schiaparelli module and its landing site in colour on the Red Planet.
