Twenty years ago, this week, NASA’s Mars Global Surveyor settled into orbit around the Red Planet, to begin what NASA described as “a sustained program of exploration” of our third-closest celestial neighbour after the […]

Hotsprings in Gale Crater? Curiosity Rover Finds New Evidence for Ancient Hydrothermal Activity

NASA’s Curiosity rover has found even more evidence for a previously habitable environment in Gale crater on Mars, according […]

5 Years on Mars, How Curiosity Pulled Off One of the Most Incredible Landings in History

For the silver foxes among us, we may remember where we were when JFK died or when Challenger breathed her last in the skies above the Kennedy Space Center (KSC). But for NASA’s Curiosity rover—which alighted on Mars, […]

'Sprained Ankle': Opportunity Rover Sends Back New Panorama from Above Ancient Gully

A portion of the new panorama showing the region just above Perseverance Valley, which is just below the crater rim. A broad notch in the rim, at right, is where water may have once flowed down through the rim and into the crater below. Image Credit: NASA/JPL-Caltech/Cornell/Arizona State Univ.

NASA’s Opportunity rover has been […]

Lockheed's Prototype Habitat Plans for NASA's Lunar Orbiting Deep Space Gateway

Orion will serve as the habitat’s command deck in early missions, providing critical communications, life support and navigation to guide long-duration missions. Credits: Lockheed Martin

Last summer, NASA selected six companies to […]

'No More Wheelies' Software Gives Curiosity Better Traction on Different Rocks

View of two of the raised treads (grousers) on the left middle wheel of the Curiosity rover which recently broke, including the one seen partially detached at the top of the wheel. NASA has now developed a new algorithm that adjusts the rover’s wheels speed depending on the rocks it’s climbing, to minimize wear […]

New Findings from Curiosity Hint Ancient Mars Lake 'Favorable for Different Microbial Life'

Mudstone lakebed sedimentary deposits seen by the Curiosity rover in Gale crater. The latest findings show that the lake in the crater was stratified and could have supported a wide variety of microorganisms. Photo Credit: NASA/JPL-Caltech

Was Mars ever habitable? Did life ever actually exist there? Those are two of the biggest questions for […]

Opportunity Rover Approaches Martian Gully After Leaving Cape Tribulation

For about the past 30 months, the Opportunity rover has been exploring Cape Tribulation on Mars, a towering ridge on the rim […]

First Breaks Seen in Treads on Curiosity Rover's Wheels, But the Journey Continues

As the Curiosity rover continues its traverse among the buttes and sand dunes of Gale […]

A Martian Paradox: Curiosity Rover Findings Raise New Questions About Water on Ancient Mars

View from Curiosity of the Yellowknife Bay rock formation. Drilled samples here and elsewhere provided evidence that this region used to be at the bottom of a lake, but also that there are little or no carbonate mineral deposits, which should have been produced if the carbon dioxide atmosphere was thicker and warmer billions […]
