MENCA (Mars Exospheric Neutral Composition Analyser) is a quadrupole mass spectrometer onboard India's Mars Orbiter Mission, MOM. A report on measurements of neutral species accepted for publication in Geophysical Research Letters is the first peer-reviewed scientific result from the mission.

Recently, space image processing enthusiast Thomas Appéré noticed that Curiosity had taken five photos of exactly the same spot on the rim of Gale crater, identical but for being taken at different times of day. That spot was due north of the rover, so the rising and lowering Sun illuminates the rounded hummocks of the crater rim differently from early morning to early afternoon.

Opportunity is continuing to explore the outcrops Marathon Valley, on the west rim of Endeavour crater.
Curiosity has spent the last month sampling and processing dark sand scooped from the side of Namib Dune. The rover has now departed Namib and is preparing to cross the Bagnold dune field, while working to diagnose an anomaly with the CHIMRA sample handling mechanism.
There have been tons and tons of HiRISE images of the Curiosity landing region, and it has taken quite a lot of work for me to find, locate, and catalogue them. This post is a summary of what I've found; after five revisions and updates, it's now version 3.0 of the list.
On January 24th, the veteran Mars Exploration Rover (MER) wrapped the last day of her 12th year of surface operations on Mars, marking an extraordinary, historic achievement for the Mars Exploration Rovers (MER) mission.

The place NASA intends to the land the first humans on Mars could be selected during the next presidential administration, according to the agency’s planetary science division director, Jim Green.
Perched on the southern wall of Marathon Valley at Endeavour Crater, Opportunity braved temperatures descending well below -100° F in December to work the winter science campaign and home in on the remnants of ancient clays.
In the six weeks since my last detailed Curiosity update, the rover has driven to, on, and around a couple of active barchan sand dunes on Mars. They are now searching for a site to scoop and sample sand on the western edge of Namib dune.
In a remarkable and wholly unexpected gift to Curiosity fans, the rover has just taken the first-ever color Mastcam self-portrait from Mars.
NASA's Next Mars Mission Delayed for Two Years
One of its main scientific instruments could not maintain a vacuum
A problem with the French space agency's seismometer instrument will delay NASA's InSight Mars lander by two years.
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.
Since my last update, Curiosity drilled two new holes, at Big Sky and Greenhorn, and is now approaching Bagnold Dunes.
