A couple of weeks ago, there was a flurry of rumor that ISRO was ready to announce some results from its Mars Orbiter Mission's methane sensor. The Indian space agency held a press event for the one-year-in-orbit anniversary of Mars Orbiter Mission and released a book containing mission photos, but did not unveil any new scientific results.

Opportunity continued her walkabout around Marathon Valley in September and sent home more evidence of significant water alteration and, perhaps, an ancient environment inviting enough for the emergence of life.

NASA held a press briefing today to publicize a cool incremental result in the story of present-day liquid water on Mars. How big a deal is this story? Was all the pre-announcement hype justified? Is this just NASA discovering water on Mars for the zillionth time? What does this mean for things many space fans care about: life on Mars or future human exploration?

Since I last checked in with Curiosity, the rover has been steadily driving southward, heading directly toward the Bagnold dune field. They are looking for a place to drill into the Stimson sandstone unit, but have been distracted by intriguing pale haloes around frock fractures. Despite a rough road, the wheels are not showing significant increase in damage.

The Mars Reconnaissance Orbiter (MRO) Context Camera (CTX) is almost a silent star at Mars. The latest MRO data release brought the total number of available CTX images to over 70,000, covering well over 90% of the Red Planet at a stunning resolution of 6 meters per pixel.

Opportunity drove farther into Marathon Valley in August, dug into what appears to be a water-altered rock, and took a lot of picture postcards in what is turning out to be a distinctively different site from any that the mission has found since the robot field geologist landed in 2004.

Since my last update, Curiosity has driven back and forth repeatedly across a section of rocks below Marias pass. The rover finally drilled at a spot named Buckskin on sol 1060, marking the drill's return to operations after suffering a short on sol 911. Now the rover is driving up into Marias Pass and onto the Washboard or Stimson unit.

Mars 2020, NASA’s next and yet-to-be-named Mars rover, will be the first mission to collect and prepare samples of the martian surface for return to Earth. The rover's engineering team has proposed a new sampling caching strategy that differs from previous concepts in some interesting ways.

NASA recently announced the Mars Cube One (MarCO) mission, which will fly two CubeSat spacecraft past Mars as part of its larger InSight Mars mission.

After three weeks of being in a communications blackout on the other side of the Sun during the Earth-Mars solar conjunction, Opportunity phoned home, reporting that she is healthy and ready to continue her mission.
