Curiosity completed work at Vera Rubin Ridge with an easy drilling activity at Rock Hall. Now it has finally driven on to mineral-rick rocks that were seen from orbit, long before Curiosity arrived. The team plans a lengthy traverse of the clay-bearing unit.

InSight mission has successfully placed the wind and thermal shield over the seismometer. The seismometer will now be shielded from winds and kept warm over the cold Martian nights, so the quality of its data should dramatically increase.

As a string of dust storms moved through Meridiani Planum and over Endeavour Crater in January, Opportunity silently wrapped her fifteenth year on the surface of Mars.

Engineers have leveled the seismometer and made progress on adjusting the position of the tether so that it doesn't interfere for the experiment. Most significantly for the mission, they have balanced the Very Broad Band sensors -- 3 of SEIS’ 6 seismic sensors -- and confirmed that they are generating good data.

It’s been a busy first three weeks on the InSight mission, and they’ve already achieved a major milestone: placing the seismometer on the ground. They've also gathered a self-portrait and 360-degree panorama.

Mars Reconnaissance Orbiter has finally spotted the InSight lander, its parachute, and its heat shield resting on the Martian surface. The images confirm the location of InSight's landing site, a little to the north and west of the center of the landing ellipse. The lander is located at 4.499897° N, 135.616000° E.

Just after a failed drill attempt at Inverness, Curiosity suffered a serious computer problem. The mission has now recovered by switching computers, and has successfully drilled at Highfield. One last drill site in

The longest-lived Martian explorer remained silent in November, presumably still sleeping at her site halfway down Perseverance Valley, along the western rim of Endeavour Crater.

In the brief period of public and political goodwill generated by NASA's latest success at the Red Planet, now is the time to secure a commitment for the next steps at Mars: sample return.

There was jubilation when InSight landed, but I'm just as happy to be writing about a distinct InSight event: The flow of raw images sent from Mars, straight to the Web, has begun.

InSight touched down on Mars today, bringing NASA's total of successful Mars landers to 8 and total number of active NASA Mars missions to 6.
