Watch Wind And Dust Obscure The Violent Traces Of Curiosity's Landing

This Impact Crater On Mars Is Just Two Years Old

Mars is covered in craters. Most of them are very old. The one you see here is, at most, two years and four months young – certified fresh, in cosmic terms. » 1/09/15 3:41pm 1/09/15 3:41pm

Sand Dunes Are Raining Across The Martian Landscape

It's raining dunes! Well, no, not really, but these olivine-rich sand dunes on Mars really do look like classic cartoon drawings of raindrops sliding across the landscape. » 1/08/15 10:07pm 1/08/15 10:07pm

It's Late Spring on Mars, and the Frost Hasn't Quite Melted Yet

Just expand this image a little bit and you'll see amazing detail — that's frost forming on ripples of sand, its distinctive wrinkly appearance created by wind whipping along this slope on the inside of a Martian crater. » 1/02/15 5:02pm 1/02/15 5:02pm

Martian Science Team Recruits Imperial Guard To Protect HiRISE Computers

The science performed by HiRISE, the telescopic camera on the Mars Reconnoissance Orbiter, is so important the research team recruited members of the Imperial Guard to stand sentry over their processing computers. Here's a sample of incredible images produced by this well-protected instrument: » 11/19/14 8:00am 11/19/14 8:00am

One Image That Reveals the Full Wonder of Martian Geology

Mars isn't just an endless stretch of dull red dirt — different parts of the planet's surface are geomorphologically distinct, with some parts boasting dunes, craters, or flood channels, while others feature evidence of avalanches, dust devil trails, and stratified terrain. » 10/14/14 7:00pm 10/14/14 7:00pm

These Are All The Places That Curiosity Didn't Land On Mars

Picking a good landing site is key for a rover mission. Here's a look at all the locations that were under consideration when deciding where to drop the Curiosity rover on Mars two years ago, set to oddly dated soundtrack. » 8/17/14 10:00am 8/17/14 10:00am

The Ancient Draa of Mars are Epic Waves of Sand

The Juventae Chasma on Mars contains dunes of all sizes, from the smallest ripples through the largest draa towering hundreds of meters tall. » 6/05/14 2:00pm 6/05/14 2:00pm

Mars Gets a New Crater, We Find it Within a Day

We have such a vigilant orbital watch program that when a meteor a few meters in diameter pinged Mars, we spotted the crater within 24 hours. We're living in the future, people. Unless this is the past, because NASA announced the discovery in Latin. » 5/22/14 3:15pm 5/22/14 3:15pm

Dunes Let Us Study One Of The Universe's Fastest Geologic Processes

With a gentle rainbow of topographical changes, and the scalloped detail of active dunes, this digital terrain model is pure indulgence for the eyes. It's also part of an ongoing study on using aeolian processes to investigate sedimentation and atmospheric science on Mars. » 5/16/14 8:00am 5/16/14 8:00am

Barchan Dunes on Mars

These dunes are a fleet of Star Fleet communicator badges (combadge), flying in formation across the Martian surface. The geomorphology of why this happens has nothing to do with Star Trek or transporter beams, and everything to do with aerodynamics. » 5/02/14 8:00am 5/02/14 8:00am

Zumba Crater, Mars

The walls on the sides of Zumba Crater on Mars are so steep, it looks like an eyeball staring back at you from the digital terrain model. The ejecta forms a hill of red and brown around the perfectly circular blue crater floor. » 4/25/14 8:00am 4/25/14 8:00am

The Mysterious Honeycomb Structures on Mars

On Mars exists a patchwork of rectangular ridges, a mysterious feature unique to the red planet. While better and better photographs narrow down the plausible theories, we still don't know exactly what created these puzzling structures. » 4/11/14 8:00am 4/11/14 8:00am

Erosion in a Martian Crater

This well-preserved crater on Mars features evidence of mass wasting — reoccurring slope linea formation. Material is being eroded from the high-elevation crater lip, forming shifting gullies into the basin below. » 4/04/14 8:00am 4/04/14 8:00am

Daaaaamn: NASA's Opportunity Rover Photographed from Mars Orbit

Check out this outstanding photo of NASA's intrepid Opportunity rover. The Agency's HiRISE camera caught a rare glimpse of the spacecraft on Valentine's day while orbiting high above the "Murray Ridge" section of the western rim of Mars' Endeavour Crater. Can you spot it? » 2/20/14 3:20pm 2/20/14 3:20pm

Nobody knows how these mysterious ridges formed on the surface of Mars

Planetary scientists studying photos of Mars's ever-changing landscape have discovered a stunning formation of bedrock ridges near the planet's equator, inside Schiaparelli Crater – but how they formed remains a mystery. » 9/17/13 1:20pm 9/17/13 1:20pm

The most beautiful images of Mars you've ever seen

Using two high-resolution photographs of the same surface, geologists can produce Digital Terrain Models (DTMs). DTMs are hugely useful to researchers looking to measure and model geological processes on other worlds. These DTMs of Mars are also absolutely gorgeous to look at. » 7/02/13 8:00am 7/02/13 8:00am

This is all the beautiful space litter left on Mars by NASA's Curiosity…

Four months ago, NASA landed a one-ton, nuclear-powered rover on the Red Planet, scattering the Martian terrain with heaps of debris in the process. Curiosity, upon arrival, shed so much of its Entry Descent & Landing hardware that high resolution images of the planet's surface are still turning up traces of the… » 12/06/12 9:00am 12/06/12 9:00am
