How CRISM picks the pixels that guide Opportunity's travels

Emily Lakdawalla • June 05, 2014

How scientists are working with CRISM, an aging but still exceptional spectrometer on Mars Reconnaissance Orbiter, to find the rocks where Opportunity's work will tell the story of ancient water on Mars.

Mars Exploration Rovers Update: Opportunity Hunts Ancient Clays along Murray Ridge

A.J.S. Rayl • June 05, 2014

At the western rim of Endeavour Crater, Opportunity spent the month of May exploring a new clayground along Murray Ridge and the Mars Exploration Rovers (MER) mission trundled into the 125th month of what was originally to be a short, 3-month tour.

Curiosity update, sols 631-644: On the road again

Emily Lakdawalla • May 30, 2014

The last couple of weeks have seen Curiosity return to the business of making steady headway toward Murray Buttes and, beyond them, Mount Sharp. Eight of the last 14 sols have seen drives ranging in length from 30 to 104 meters, racking up a total of more than half a kilometer. They are now occasionally working a shortened planning timeline that allows them to squeeze more drive sols into Curiosity's schedule.

A Mars year's worth of Sun images from Opportunity demonstrates Mars' orbital motions as reflected in the changing apparent position of the Sun: the analemma.

Image processing trick: Removing interline transfer smear from Curiosity photos

Emily Lakdawalla • May 01, 2014

Curiosity took a new self-portrait on sol 613. This post contains a tip for would-be Curiosity image processors on how to make their Curiosity mosaics better: removing the smearing effect of bright objects in MAHLI photos.

Curiosity update, sols 597-610: Picking a drill site at the Kimberley

Emily Lakdawalla • April 24, 2014

After completing the initial reconnaissance of the Kimberley outcrop two weeks ago, Curiosity is, at last, moving toward a drill site. The science team selected the location last week: a spot near the base of Mount Remarkable, into what they have been calling the "middle unit" at the Kimberley.

The End of Opportunity and the Burden of Success

Casey Dreier • April 15, 2014

The Opportunity rover and the Lunar Reconnaissance Orbiter are both zeroed out in NASA's 2015 budget. Learn why these missions face the axe and why the White House is forcing NASA to choose between existing missions and starting new ones.

Pretty picture: Sunset over Gale crater

Emily Lakdawalla • April 14, 2014

Imagine yourself on a windswept landscape of rocks and red dust with mountains all around you. The temperature -- never warm on this planet -- suddenly plunges, as the small Sun sets behind the western range of mountains.

Curiosity update: Initial reconnaissance of the Kimberley, sols 585-595

Emily Lakdawalla • April 11, 2014

Curiosity has been busy performing a survey of the Kimberley, walking the length of the outcrop and taking enormous quantities of photos. The team is now ready to go in for a closer look, and maybe even to drill.

Will We Finally Rove Mawrth Vallis?

J. Brian Balta • April 10, 2014

Mawrth Vallis was axed as a landing site for Curiosity, but will we get a chance to explore it with ESA's ExoMars rover?

Look how clean Opportunity is now!

Emily Lakdawalla • April 09, 2014

While climbing Murray Ridge, Opportunity enjoyed a major cleaning event that has left the rover's solar panels more dust-free than they have been in years. The rover captured a pretty panorama of the newly clean deck with its Pancams, and James Sorenson processed the version shown here.
