Observations by NASA’s Curiosity Rover indicate Mars’ Mount Sharp was built by sediments deposited in a large lake bed over tens of millions of years.
This interpretation of Curiosity’s finds in Gale Crater suggests ancient Mars maintained a climate that could have produced long-lasting lakes at many locations on the Red Planet.
“If our hypothesis for Mount Sharp holds up, … Read the rest of this article
Thanks to a break in the dusty ‘weather’ over the giant Hellas Basin at the beginning of this year, ESA’s Mars Express was able to look down into the seven kilometre-deep basin and onto the frosty surface of Hellas Chaos.
Hellas Basin sits in the southern highlands of Mars and is one of the Solar System’s largest impact basins, with … Read the rest of this article

Among the most interesting landforms on Mars are features referred to as ‘chaotic terrain’. Dozens or even hundreds of isolated mountains up to 2,000 m high are scattered … Read the rest of this article

This composite Hubble Space Telescope image (click image for larger view) captures the positions of Comet Siding Spring and Mars in a never-before-seen close passage of a comet by the Red Planet, which happened at 2:28 p.m. EDT October 19, 2014. On that date the comet passed by Mars at approximately 87,000 miles (about one-third the distance between Earth and … Read the rest of this article
This weekend, Comet Siding Spring (C/2013 A1) will make a historically close approach to Mars. Satellites and rovers will get an eye-full as the green comet passes less than 140,000 km (87,000 miles) above the Red Planet’s surface. No one knows what will happen. Possible side-effects of the flyby include a Martian meteor shower and auroras. These videos from a … Read the rest of this article

Three views of an escaping atmosphere (click image for larger view), obtained by MAVEN’s Imaging Ultraviolet Spectrograph, are shown here. By observing all of the products of water and carbon dioxide breakdown, MAVEN’s remote sensing team can characterize the processes that drive atmospheric loss on Mars. These processes may have transformed the planet from an early Earthlike climate to the … Read the rest of this article
NASA’s extensive fleet of science assets, particularly those orbiting and roving Mars, have front row seats to image and study a once-in-a-lifetime comet flyby on Sunday, Oct. 19.
Comet C/2013 A1, also known as comet Siding Spring, will pass within about 87,000 miles (139,500 kilometers) of the Red Planet — less than half the distance between Earth and our moon … Read the rest of this article
After 10-month voyage across more than 400 million miles of empty space, NASA’s MAVEN spacecraft reached Mars on Sept. 21st 2014. Less than 8 hours later, the data started to flow.
“Our Imaging Ultraviolet Spectrograph (IUVS) obtained these false-color images of Mars on Sept. 22nd,” says Nick Schneider who leads the instrument team at the University of Colorado. … Read the rest of this article
