On sol 3451 Opportunity began its climb of Solander Point. This is the highest “mountain” that Opportunity has tried to climb yet.

The Martian Geologic Time Scale is a lot more complicated than the Moon's.

After a brief science stop at Darwin (formerly known as Waypoint 1), Curiosity has driven hundreds of meters toward Mount Sharp. Autumn has come to Curiosity's southern hemisphere location, bringing lower temperatures. That means more power is required to heat rover actuators, leaving less power for science along the drive.

It all started when we read a book called, There's Nothing to Do on Mars, by Chris Gall. And then something wonderful happened.

What did I learn about Curiosity at last week's Division for Planetary Sciences meeting? There were a few talks, most of which concerned soil and atmsospheric chemistry. I can summarize their conclusions with one sentence: More data is needed.

Twelve years on, Mars Odyssey just keeps sending great images.

The Mars Exploration Rover (MER) mission stepped up preparations for the coming Martian winter in September as Opportunity rounded the northern tip of Solander Point and drove into what will be her campground at Endeavour Crater for the next six months or so. It's been nearly a year in the planning. Now, from the rover's first look around, this winter could turn out to be one for the books.

The European Space Agency invited me to join Mars Express project scientist Olivier Witasse, and spacecraft oeprations manager Michel Denis for a Hangout on Europe's recent and future exploration of Mars and Phobos.

Launch preparations will resume for NASA's MAVEN spacecraft, due to launch to Mars on November 18th. Work had previously been suspended, potentially causing the spacecraft to miss its once-every-26-month launch opportunity.

I've been delving in to the Mars Express image archive this week, checking out its images of Phobos, and found a couple of really cool time-series of images to assemble into animations.

Some brand-new images just arrived from Curiosity on Mars, and two of the most recent are Mars Hand Lens Imager (MAHLI) images of the wheels. Today's images contained two little surprises.

NASA confirmed that a government shutdown could affect pre-launch processing of the MAVEN spacecraft, currently scheduled to launch to Mars on November 18th.

The European Space Agency will announce two major science missions this November, one of which is likely to be devoted to solar system exploration.

Curiosity looked up after dark and captured more cool photos of Mars' moons. They include Phobos and Deimos passing in the night, and Phobos entering Mars' shadow.

Pay attention! This Mars orbiter, headed for launch in November, is a terrific science mission, as Mat Kaplan learned in a recent workshop, and in this week's Planetary Radio.

Take a spin around the Red Planet with the trusty orbiter.
