SwRI-Led Team Discovers Lull in Mars' Giant Impact History.

From the earliest days of our solar system's history, collisions between astronomical objects have shaped the planets and changed the course of their evolution.

Martian Gullies

This is an odd-looking image. It shows gullies during the winter while entirely in the shadow of the crater wall. Illumination comes only from the winter skylight.

Opportunity Leaves Cape Tribulation

Opportunity Leaves Cape Tribulation

NASA's senior Mars rover, Opportunity, is departing "Cape Tribulation," a crater-rim segment it has explored since late 2014, southbound for its next destination, "Perseverance Valley."


Mars Has Metal in Its Atmosphere

Mars Has Metal in Its Atmosphere

Mars has electrically charged metal atoms (ions) high in its atmosphere, according to new results from NASA's MAVEN spacecraft.


Mars Reconnaissance Orbiter Completes 50,000 Orbits

Mars Reconnaissance Orbiter Completes 50,000 Orbits

The most data-productive spacecraft yet at Mars swept past its 50,000th orbit this week, continuing to compile the most sharp-eyed global coverage ever accomplished by a camera at the Red Planet.


India's Mars Orbiter Views Eridania Quadrangle of Mars

India's Mars Orbiter Views Eridania Quadrangle of Mars

This image covers about 310 km x 310 km area with 154 m per pixel resolution in Eridania quadrangle of Mars, adjacent to Mare Cimmerium on it right and Muller crate to its left in the southern hemisphere at areographic region centered around (24 S, 133 E).


Does Mars Have Rings? Not Right Now, But Maybe One Day

Does Mars Have Rings? Not Right Now, But Maybe One Day

As children, we learned about our solar system's planets by certain characteristics -- Jupiter is the largest, Saturn has rings, Mercury is closest to the sun.


MRO Tracks Back-to-Back Regional Dust Storms

MRO Tracks Back-to-Back Regional Dust Storms

A regional dust storm currently swelling on Mars follows unusually closely on one that blossomed less than two weeks earlier and is now dissipating, as seen in daily global weather monitoring by NASA's Mars Reconnaissance Orbiter.


The North Polar Layers of Mars

The North Polar Layers of Mars

The North Polar layered deposits are a 3-kilometer thick stack of dusty water ice layers that are about 1000 kilometers across.


Martian Winds Carve Mountains, Move Dust, Raise Dust

Martian Winds Carve Mountains, Move Dust, Raise Dust

On Mars, wind rules. Wind has been shaping the Red Planet's landscapes for billions of years and continues to do so today. Studies using both a NASA orbiter and a rover reveal its effects on scales grand to tiny on the strangely structured landscapes within Gale Crater.


Mars May Be More Earth-like Than Moon-like

Mars May Be More Earth-like Than Moon-like

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 Reconnaissance Orbiter Checks Possible Landing Sites

Mars Reconnaissance Orbiter Checks Possible Landing Sites

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.
