Since my last update, Curiosity drilled two new holes, at Big Sky and Greenhorn, and is now approaching Bagnold Dunes.

On October 28th, the Cassini spacecraft flew through the geyser plume of Saturn's moon Enceladus. But Cassini was not the only spacecraft operating in the solar system that day.

Since I last checked in with Curiosity, the rover has been steadily driving southward, heading directly toward the Bagnold dune field. They are looking for a place to drill into the Stimson sandstone unit, but have been distracted by intriguing pale haloes around frock fractures. Despite a rough road, the wheels are not showing significant increase in damage.

Since my last update, Curiosity has driven back and forth repeatedly across a section of rocks below Marias pass. The rover finally drilled at a spot named Buckskin on sol 1060, marking the drill's return to operations after suffering a short on sol 911. Now the rover is driving up into Marias Pass and onto the Washboard or Stimson unit.

I'm back from two weeks' vacation, so it's time to catch up on the status of all our intrepid planetary missions, from Akatsuki to the Voyagers and hitting the Moon, Mars, asteroids, comets, and Saturn in between.

It’s been an eventful few weeks for Curiosity on Mars. From sols 981 to 986, Curiosity’s human pilots tried and failed to drive the rover southward; but, retracing their steps to Logan's Run, they quickly found a way up and into a beautiful geological amphitheater named Marias Pass, where they will stay throughout Mars solar conjunction. They also returned ChemCam to normal operations.

Pause your life for six minutes and watch the Sun set....on Mars. Thank you, Glen Nagle, for this awe-inspiring simulation based on Curiosity's sol 956 sunset images.

Digging in to mission image archives yields similar images of layered Martian rocks from very different places.

Curiosity is finally on the road again! And she's never taken a more scenic route than this. Her path to Mount Sharp is taking her to the west and south, across sandy swales between rocky rises.

Long before Curiosity's landing, the description of the color camera made ​​me dream: I imagined what wonderful pictures we could get of sunsets and sunrises on Mars. They finally came on sol 956, the 15th of April, 2015.

Since I last wrote about Curiosity drilling at Pink Cliffs, the rover has visited and studied two major sites, drilling at one of them. It has also suffered a short in the drill percussion mechanism that presents serious enough risk to warrant a moratorium on drill use until engineers develop a plan to continue to operate it safely.

In pictures of the planets, the stars aren't usually visible. But when they do appear, they're spectacular.

Dawn has successfully entered orbit at Ceres, becoming the first mission to orbit a dwarf planet and the first to orbit two different bodies beyond Earth. I also have updates on Curiosity, Rosetta, Mars Express, Hayabusa2, the Chang'e program, InSIGHT, and OSIRIS-REx.

Curiosity's second drilling campaign at the foot of Mount Sharp is complete. The rover spent about a month near Pink Cliffs, an area at the base of the Pahrump Hills outcrop, drilling and documenting a site named Mojave, where lighter-colored crystals were scattered through a very fine-grained rock.

A FOIA request offers insight into NASA's planetary science extended mission review process, which seems, at best, confusing, and at worst—with adjectival ratings like “Very Good/Good”—arbitrary.
