Curiosity Update, Sols 2257-2312: Drilling at Rock Hall and Arrival at the Valley of Clay
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.
So long, MarCO, and thanks for the radio transmissions
NASA says it does not expect to receive any more transmissions from the MarCO CubeSats that accompanied Insight to Mars last year.
InSight Milestone: Wind and Thermal Shield Placed Sol 66
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.
The Mars Exploration Rovers Update: Opportunity Logs 15th Year in Silence, Team Begins 'Hail Mary' Efforts
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.
InSight Update, sols 25-42: Seismometer sensors working!
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.
The Mars Exploration Rovers Update: Opportunity Still Silent, Team Still Hopeful
It’s now been more than six and a half months that the longest-lived robot on another planet has been incommunicado.
InSight update, sols 1-24: Operations begin, first instrument deployed
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 Spots InSight Hardware on Mars
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.
Curiosity Update, Sols 2163-2256: Hard Times Atop Vera Rubin Ridge
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 Mars Exploration Rovers Update: Team Continues Search for Opportunity’s Signal as Windy Season Begins
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.
After the Success of InSight, It’s Time for NASA to Commit to Mars Sample Return
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.
New Cameras on Mars!
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 has landed (UPDATED)
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.
Here's where China is looking to land its 2020 Mars rover
NASA's Mars 2020 rover isn't the only spacecraft heading to Mars in two years.
This Thanksgiving, avoid the politics and talk space instead
If you're expecting to gather with extended family on Thanksgiving, avoid the politics. Here are some conversation starters to use at the dinner table that everyone can engage in.
We're going to Jezero!
NASA announced this morning the selection of Jezero crater for the landing site of the Mars 2020 mission. Jezero is a 45-kilometer-wide crater that once held a lake, and now holds a spectacular ancient river delta.
What to Expect When InSight Lands on Mars
If all goes well, anxious space fans on Earth will learn of a successful InSight landing on Mars on Monday, 26 November 2018, at 19:53 UTC. Here's a preview of all the landing day events.
The Mars Exploration Rovers Update: NASA Green-Lights Team to Continue Opportunity Recovery Plan into 2019
October came and went without a beep from Opportunity, silence that was still no surprise for some, but a little discouraging for other members of the rover team.
MAVEN, in orbit around Mars, snaps anniversary selfie
The spacecraft used its ultraviolet spectrograph imager for the job, and one frame shows Mars in the background.
The Mars Exploration Rovers Update: Team Initiates Plan to Recover Oppy, Orbiter Sends Postcard, Storm Ends
As the global storm that wrapped the Red Planet in a cloud of dust since late June finally gave up the ghost in September, the sky continued to clear over Endeavour Crater and the Opportunity team initiated the NASA-approved two-step plan to reestablish contact with the rover.
