Yesterday at the American Geophysical Union meeting, the Curiosity science team announced the discovery of a mineral never before found on Mars. The finding was the result of a fortuitous series of events, but as long as Curiosity's instruments continue to function well, it's the kind of discovery that Curiosity should now be able to repeat.
Opportunity faced the challenges of winter as well as technological issues in November, but pressed on, hiking up hill and into a geological treasure trove that may well present the scientists with the evidence they need to solve the clay mineral mystery of Marathon Valley.
There have been several important pieces of news about European missions in the last month: Rosetta's fate has been determined; ExoMars Trace Gas Orbiter's launch is slightly delayed; and they have selected a landing site for the ExoMars rover.
An introduction to the Mastcam-Z stereo imager on the Mars 2020 rover, and brief reporting and reflections on team meetings, science instruments, and the exciting future of The Planetary Society covering the entire lifetime of this instrument, from design to Mars images.
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.
