Today, the Opportunity rover attempted a difficult, never-before-possible feat: to shoot a photo of an arriving Mars lander from the Martian surface. Unfortunately, that attempt seems not to have succeeded. Opportunity has now returned the images from the observation attempt, but Schiaparelli is not visible.

Trace Gas Orbit is successfully in orbit at Mars, but the fate of the Schiaparelli lander is uncertain.

Schiaparelli is GO for landing, and ExoMars TGO is GO for orbit insertion! When to expect ExoMars events: Schiaparelli separation, final trajectory maneuvers, landing events, orbit insertion, and press briefings.

In the two months since my last Curiosity update, the rover has traversed the scenic Murray Buttes, drilled at Quela, and driven another 300 meters southward.

It's always a delight to sink my teeth into a new data set, and I have spent this week playing with one I've been anticipating for a long time: ISRO's Mars Orbiter's Mars Colour Camera, or MCC. MCC is unique among current Mars cameras in its ability to get color, print-quality, wide-angle, regional views of Mars.

On Mars Orbiter Mission’s second anniversary of Mars arrival, ISRO has (finally!) made available to the public data from its first year in orbit.

It was another September to remember for Opportunity as she cruised through the Lewis and Clark Gap and out of Marathon Valley, then hiked downslope, leading the first overland expedition of the Red Planet to Spirit Mound, a new site deep in Endeavour Crater’s rim.

SpaceX's plans to colonize Mars differ considerably from NASA's Journey to Mars ambitions. But direct comparison is difficult. SpaceX is able to wipe the slate clean and start fresh with a bold new approach to humans in space. NASA has no such luxury, and must use existing pieces and people to make their goals a reality.

Opportunity is about to leave Marathon Valley for good and head south into the next valley, marking the beginning of the current extended mission plan.

Opportunity got in the groove at Endeavour Crater in August finishing the last of her science assignments in Marathon Valley.

Whenever I share images from Curiosity, among the most common questions I’m asked is “what is the scale of this image?” With help from imaging enthusiast Seán Doran, I can answer that question for some of the Murray buttes.

Curiosity has now covered most of the flat ground that lay between the Naukluft plateau and the Murray buttes. The mission took only 11 days to complete drilling work at Marimba, despite a recurrence of a problematic short in the drill. The rover is ready to drive in among the buttes, shooting spectacular photos along the way.

Despite the intensifying rancor and ugliness of the U.S. Presidential campaigns on Earth, as the spring Sun shined down on Meridiani Planum in July, all was right with the world at Endeavour Crater.

Opportunity is finishing up its activities in Marathon Valley, getting ready to hit the road again.

The Mars 2020 mission will carry microphones in its EDL package and its SuperCam instrument, which will enable us to finally hear the sounds of Mars. The Planetary Society has been trying to get microphones to Mars for 20 years and is ecstatic that these will fly.

NASA's next Mars rover is rolling off the drawing board and into its final design and fabrication phase, the agency announced today, during a televised event at the Jet Propulsion Laboratory that highlighted some of the mission's technology.

The Mars Exploration Rover (MER) mission entered its 150th month of surface exploration in June as Opportunity began checking off the last science investigations in Marathon Valley, and the crew on Earth looked ahead to the future past.

Today ESA released ExoMars Trace Gas Orbiter's first photo of Mars, taken from a distance of 41 million kilometers. It's no more detail than you can get through a pair of a binoculars, just a little taste of what's to come.
