Pretty picture: Sunset over Gale crater

Posted by Emily Lakdawalla on 2014/04/14 10:38 CDT | 5 comments

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.

Posted by Casey Dreier on 2014/04/04 12:11 CDT | 4 comments

Earlier this week, NASA announced that it was cutting off ties with Russia, except for activities relating to the ISS. This raised questions about Russian participation on NASA's science missions, particularly the Russian experiment on the Curiosity rover.

Snapshots of Science from the 2014 Lunar and Planetary Science Conference

Posted by Emily Lakdawalla on 2014/03/25 02:45 CDT | 2 comments

Vignettes from dozens of LPSC talks: GRAIL and LADEE at the Moon; ice and craters and conglomerates and organics and gullies on Mars; polar deposits and volatile elements on Mercury; tectonics on Enceladus; and more, until my brain was so full I could barely speak.

Curiosity update, sols 549-562: Shooting past Kylie on the road to Kimberley

Posted by Emily Lakdawalla on 2014/03/06 07:35 CST | 7 comments

In a series of drives, Curiosity flew past the "striated terrain" that outcropped at Kylie, and is now negotiating her way around some rockier territory as she makes her way south toward the enticing outcrops of Kimberley.

A new map of Mars from some pretty old data

Posted by Emily Lakdawalla on 2014/03/04 11:46 CST | 3 comments

The United States Geological Survey recently issued an improved version of the Viking color map of Mars. This 40-year-old data set still provides the prettiest global-scale map of the planet.

Sand Waves in the Desert
or “Pet Peeves and Deciphering Climate Change in the Solar System”

Posted by Lori Fenton on 2014/02/21 03:19 CST | 1 comments

I have a pet peeve: the words dune and ripple are often used interchangeably, although they are quite distinct from one another. So what’s the difference between aeolian dunes and ripples? And why should anybody care?

Curiosity update, sols 540-8: New rules and longer drives

Posted by Emily Lakdawalla on 2014/02/20 05:53 CST | 3 comments

Curiosity has tested a new driving mode -- backwards -- and achieved their longest single-day drive in three months. And they've committed to driving to the spot formerly known as "KMS-9," marking that commitment by giving it a name, "Kimberley." My route maps show you why Curiosity's views will be shifting, and Ken Herkenhoff's blog posts explain the daily activities.

Curiosity Update, sols 534-540: Over Dingo Gap, onto softer sand

Posted by Emily Lakdawalla on 2014/02/13 12:55 CST | 5 comments

After more than two months of very slow driving due to concern about the wheels and time spent choosing whether to enter "Dingo Gap" or not, Curiosity has safely crossed the dune and resumed longer drives, achieving 75 meters and crossing the 5-kilometer mark on sol 540.

HiRISE image coverage of the Curiosity field site on Mars

Posted by Emily Lakdawalla on 2014/02/10 02:39 CST

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.

Curiosity update, sols 521-533: Assessing Dingo Gap

Posted by Ken Herkenhoff on 2014/02/04 05:08 CST | 3 comments

While continuing to perform regular wheel health assessments, Curiosity took a sharp right turn and headed for Dingo Gap. On sol 533, they performed a "toe dip" that parked the rover atop the dune with a good view down into the valley.

Curiosity update: imaging the nonfunctioning REMS boom, closer to Dingo Gap

Posted by Emily Lakdawalla on 2014/01/29 04:22 CST | 2 comments

At long last, on sol 526, Curiosity imaged the part of the weather instrument that was damaged during landing, but no obvious damage is visible, to me anyway. On sol 527 they drove even closer to Dingo Gap, with plans to drive onto the dune in the sol 528 drive.

Curiosity images "Dingo Gap," sols 519-521

Posted by Emily Lakdawalla on 2014/01/24 05:45 CST | 1 comments

Over the last few days, Curiosity made steady driving progress to the southwest. For several of those days, an intriguing feature has appeared on the horizon in her images. UPDATE: The Curiosity team has now decided to drive the rover toward the feature, which is now named "Dingo Gap."
