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 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.

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.

Animated maps of the planets show the spheres in motion.

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 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

Why didn't we discover Pluto's moons until more than a decade after Hubble launched? Mark Showalter helps me answer this question.

Imagine flying deep within the asteroid belt to study the most unreachable location in the solar system: the deep core of a terrestrial world.

I've been fascinated by Mercury's hollows ever since MESSENGER discovered them. Two recent papers look at where they are found to try to figure out how they form.

Upcoming deep space missions will venture right to the heart of the Solar System.

Cassini flew past Phoebe on June 11, 2004, on its way to entering Saturn orbit. The flyby was almost perfect but overexposure of some images have prevented color mosaics from being produced. Even though Phoebe's body is gray and dull in color, the absence of color images always provoked me. By using VIMS data, I have now produced color mosaics.

Exploring a set of newly named hills on Mars reveals tantalizing clues to the planet's story.

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.

The Mars Exploration Family Portrait is expanding to cover the entire solar system! But before we proceed, I'm asking for feedback.

Cosmos returns in fine form in its penultimate episode. Sagan explores the historical and scientific precedents for the search for extraterrestrial life (SETI) and our human desires to not be alone in the universe.

A few days ago, Curiosity looked westward after sunset and photographed Earth setting toward the mountainous rim of Gale crater.

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
