We are now only about 180 meters from the new mountain, Solander Point. We slowed down this week so that we could check out the rocks here where there is a strange hydration signature from orbital remote sensing.

The HiRISE camera on Mars Reconnaissance Orbiter has snapped a lovely color photo of the rim of Endeavour crater, catching Opportunity midway between Nobby's Head and Solander Point.

The fictional world Tatooine, scene of action in the Star Wars movies, is named after a town in Tunisia, where parts of the movies were filmed. The desert backdrops against which the movies were filmed are real terrestrial landscapes, which prove to be perhaps unexpectedly dynamic.

Time is kept differently on Mars. This is because Mars itself rotates a little slower than Earth. This proves to be a pain when it comes to timekeeping.

The Mars Exploration Rover (MER) mission celebrated its 10th anniversary of leaving Earth in June, as Opportunity continued the sprint to its next winter haven at Endeavour Crater.

It had never occurred to me to think about geostationary satellites in Mars orbit before reading a new paper by Juan Silva and Pilar Romero. The paper shows that it takes a lot more work to maintain a stationary orbit at an arbitrary longitude at Mars than it does at Earth.

ESA celebrated the tenth anniversary of Mars Express' launch with a several-day science meeting during which they issued lots of press releases and numerous spectacular photos. My favorite of them all is this enormous image of Kasei Valles on Mars.

The House of Representatives held a hearing today to discuss their proposed NASA authorization bill, which would fund Planetary Science, cut Earth Science, forbid asteroid retrieval, and command NASA to pursue a path to Mars via the Moon.

Mars Express has been in flight for a decade, more than enough time to send home some amazing finds.

Just some cool photos of Curiosity lighting up the Cumberland drill hole after sunset for a little nighttime science work.

There was a Curiosity telephone conference this morning to make an exciting announcement: they're (almost) done at Glenelg and are preparing for the drive south to Mount Sharp. Allow me an editorial comment: finally!

It was a merry and mighty month of May for the Mars Exploration Rover mission: Opportunity finished a blockbuster study of Matijevic Hill finding the best evidence yet for an ancient, potentially habitable environment, and then embarked on its first real road trip in two years. The robot field geologist had barely gotten underway on its journey when it surpassed the Apollo 17 lunar rover distance record to become the most traveled NASA vehicle on another planetary body.

I'm absolutely floored when I stop to think that our beautiful blue ocean is only one of perhaps a half dozen or more oceans on other worlds in our solar system, and only one of probably millions (or more) oceans on other Earth-like planets in our galaxy. Oceans abound!

Nothing reflects the romance of deep space exploration more than the evocative names of places on the planets and moons.

Mars Exploration Rover Opportunity left Cape York on May 14th and embarked on a 2-kilometer journey south along the western rim of Endeavour Crater. The rover is heading now to Solander Point, where it will spend the coming Martian winter.

Opportunity finally started driving south from its location on the outcrop where it had been since solar conjunction.
