Rosetta's comet target, 67P/Churyumov-Gerasimenko, has emerged from behind the Sun as seen from Earth, and the Very Large Telescope has photographed it. The new images show that cometary activity has already begun as Rosetta approaches for its August rendezvous.
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.

The Mars Exploration Rover mission put its 10th anniversary in the rear view mirror in February and roved on into its 11th year of surface operations at Endeavour Crater.

Seeing hardware that was built by human hands sitting on the surface of another planet never, ever gets old. Today, the Lunar Reconnaissance Orbiter Camera team released two new images of Chang'e 3 and Yutu on the Moon.
Over the weekend, Chinese state news agency Xinhua reported in both Chinese and English a little bit more information on what has stilled the Yutu rover's motions across the lunar surface: "a control circuit malfunction in its driving unit."
Continuing its daring mission to explore some of the last uncharted worlds in the inner solar system, Dawn remains on course and on schedule for its rendezvous with dwarf planet Ceres next year.
Opportunity is still exploring an outcrop high up on Murray Ridge as the winter solstice on Mars approaches. At this location the tilts are good, so Opportunity is getting excellent solar input on its solar panels.

Today is the tenth anniversary of Opportunity's landing on Mars. Here at the New Mexico Museum of Natural History and Science, we just opened a tenth anniversary exhibit.

Opportunity arrived at the location that has been the target of all this climbing since late last (Earth) summer. We will settle in for some detailed work on the outcrop here since this appears to be something different from the impact breccias that we have been seeing along the ridge crest.
During the third lunar day of Change'3 surface operations the lander operated normally, performing ultraviolet astronomy and imaging Earth's plasmasphere. The rover's instruments were working, but the rover did not move.
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.
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.
A terse Xinhua news report posted today says there may be some sign of life from Yutu, now that the Sun has risen on the third lunar day since Chang'e 3 landed. It is frustratingly non-specific. UPDATE: Amateur radio operators have detected a radio signal from the rover.

Promoting the story of Yutu to the Chinese public through social media: a successful case of science outreach.
A hundred days after launch, India's Mars Orbiter Mission is doing just fine, and so is NASA's MAVEN.

In the storied history of the Mars Exploration Rovers (MER) mission, January 2014 will likely be remembered as one of the most memorable months of all.
It's with great sadness that I report that the Goddard Space Flight Center team has determined that we will not be able to regain control of the venerable spacecraft ICE/ISEE-3 when it passes by Earth this year, after a 30-year journey around the Sun.
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.
The European Space Agency announced yesterday a significant milestone in the development of the next Mars mission: the core module of the ExoMars Trace Gas Orbiter has been delivered.
