Curiosity update, sols 1489-1547: Drilling at Sebina, driving up through Murray, drill problems at Precipice

Emily Lakdawalla • December 12, 2016

It's been a drive-heavy two months for Curiosity. Since my last update, the rover has drilled at a site named Sebina, then traveled about 500 meters to the south across increasingly chunky-looking Murray rocks to a new attempted drill site at Precipice. They were planning to attempt a new drilling technique at Precipice, but encountered a new problem with the drill instead.

Field Report from Mars: Sol 4577 - December 9, 2016

Larry Crumpler • December 09, 2016

Opportunity has begun the ascent of the steep slopes here in the inner wall of Endeavour crater after completion of a survey of outcrops close to the crater floor. The goal now is to climb back to the rim, drive south, and arrive at the next major mission target on the rim before the next Martian winter.

Mars Exploration Rovers Update: Opportunity Departs Spirit Mound, Embarks on Toughest Exit Ever

A.J.S. Rayl • December 02, 2016

Opportunity worked along Endeavour Crater's western rim through November, taking pictures, hiking slopes, and finishing work in the depths of Cape Tribulation.

Schiaparelli investigation update; crash site in color from HiRISE

Emily Lakdawalla • November 23, 2016

ESA issued an update on the Schiaparelli landing investigation today, identifying a problem reading from an inertial measurement unit as the proximate cause of the crash. Meanwhile, ExoMars Trace Gas Orbiter is operating its science instruments for the first time this week, and HiRISE has released calibrated versions of the Schiaparelli crash site images.

Subsurface Water Ice in Utopia Planitia, Mars

Cassie Stuurman • November 22, 2016

Martian radar expert Cassie Stuurman explains how the SHARAD instrument aboard NASA's Mars Reconnaissance Orbiter was used to detect buried ice deposits.

HiRISE coverage of the Opportunity field site, version 1.0

Emily Lakdawalla • November 18, 2016

As she did before for Curiosity, Emily Lakdawalla has searched through the HiRISE image archive for photos of the Opportunity landing site and sorted them all out so that you don't have to.

NatGeo's new MARS miniseries premieres tonight

Casey Dreier • November 14, 2016

The new six-part miniseries, MARS, premieres tonight on the National Geographic channel. Perhaps it can help influence the incoming administration to continue NASA's Journey to Mars.

A roundup of pretty pictures and news from our robotic ambassadors around the solar system, from November 4 through 8.

Mars Exploration Rovers Update: Opportunity Scales Spirit Mound, Takes Shot at Schiaparelli

A.J.S. Rayl • November 05, 2016

Opportunity spent the month of October on Spirit Mound studying the rich yet familiar geology at the first science stop on its 10th extended mission – pausing only to take a shot at freeze-framing part of the descent of Europe’s Schiaparelli lander.

Capturing Martian Weather in Motion

Justin Cowart • November 04, 2016

Still images of Mars often give a false impression that Mars is a dead planet—but time-lapse imaging from the European Mars Express spacecraft reveals the planet as it really is.

Field Report From Mars: Sol 4535 - October 26, 2016

Larry Crumpler • November 02, 2016

Opportunity is currently finishing up observations of its first outcrop target of its 10th extended mission plan.

Schiaparelli crash site imaged by HiRISE

Emily Lakdawalla • October 27, 2016

Following up the detection of the Schiaparelli crash site by Mars Reconnaissance Orbiter CTX, the higher-resolution HiRISE camera has now definitively identified the locations of lander impact site, parachute with backshell, and heat shield impact site on the Martian surface.

Likely Schiaparelli crash site imaged by Mars Reconnaissance Orbiter

Emily Lakdawalla • October 21, 2016

Just a day after the arrival of ExoMars Trace Gas Orbiter and its lander Schiaparelli, Mars Reconnaissance Orbiter has taken a photo of the landing site with its Context Camera, and things do not look good.

Brief update: Opportunity's attempt to image Schiaparelli unsuccessful

Emily Lakdawalla • October 19, 2016

Today, the Opportunity rover attempted a difficult, never-before-possible feat: to shoot a photo of an arriving Mars lander from the Martian surface. Unfortunately, that attempt seems not to have succeeded. Opportunity has now returned the images from the observation attempt, but Schiaparelli is not visible.

ExoMars: Long day’s journey into uncertainty

Ruth McAvinia • October 19, 2016

Trace Gas Orbit is successfully in orbit at Mars, but the fate of the Schiaparelli lander is uncertain.

ExoMars update: Timeline for separation and orbit insertion

Emily Lakdawalla • October 14, 2016

Schiaparelli is GO for landing, and ExoMars TGO is GO for orbit insertion! When to expect ExoMars events: Schiaparelli separation, final trajectory maneuvers, landing events, orbit insertion, and press briefings.

Curiosity Update, sols 1428-1488: Through the Murray Buttes, drilling at Quela, and beyond

Emily Lakdawalla • October 13, 2016

In the two months since my last Curiosity update, the rover has traversed the scenic Murray Buttes, drilled at Quela, and driven another 300 meters southward.

Fun with a new image data set: Mars Orbiter Mission's Mars Colour Camera

Emily Lakdawalla • October 06, 2016

It's always a delight to sink my teeth into a new data set, and I have spent this week playing with one I've been anticipating for a long time: ISRO's Mars Orbiter's Mars Colour Camera, or MCC. MCC is unique among current Mars cameras in its ability to get color, print-quality, wide-angle, regional views of Mars.

MOM's Second Anniversary at Mars

Sandhya Ramesh • October 05, 2016

On Mars Orbiter Mission’s second anniversary of Mars arrival, ISRO has (finally!) made available to the public data from its first year in orbit.

Mars Exploration Rovers Update: Opportunity Exits Marathon Valley then Rocks Spirit Mound

A.J.S. Rayl • October 04, 2016

It was another September to remember for Opportunity as she cruised through the Lewis and Clark Gap and out of Marathon Valley, then hiked downslope, leading the first overland expedition of the Red Planet to Spirit Mound, a new site deep in Endeavour Crater’s rim.
