Observations made by the Mars Climate Sounder, an instrument aboard NASA’s Mars Reconnaissance Orbiter, have revealed new information about atmospheric tides on the Red Planet.

It seems like it was just yesterday that 2000 people gathered in the Pasadena Convention Center to celebrate Curiosity's landing on Mars. All of Planetfest 2012 is online for your enjoyment.

This week Opportunity finished up a quick investigation of the strange rocky terrain out here in the plains where it is approaching the next mountain rim segment of Endeavour crater, Solander Point.

The Mars Exploration Rovers (MER) mission Opportunity celebrated the 10th anniversary of its launch on July 7, 2003, and then went on to complete the last leg of its 2 km trek from Cape York to Solander Point. But just before the robot field geologist pulled onto the actual base of the ridge where it will spend its sixth Martian winter, Mars lured the team off the path with some of the weirdest Martian rocks the scientists have seen yet.

It seems like my attention wandered for just a moment, and all of a sudden Curiosity is really on the road. She's racked up drive after drive, methodically eating up the terrain between here and her goal: the ancient rocks at the foot of Mount Sharp.

They're too far apart to have a party, but today Curiosity and Opportunity could have rung in the New Mars Year. Today Mars reached a solar longitude of zero degrees and the Sun crossed Mars' equator, heralding the arrival of spring in the northern hemisphere and autumn in the southern hemisphere.

We now know the science goals for NASA’s next major Mars mission. The new rover will further the astrobiological search begun by the Curiosity rover and store samples for eventual return to the Earth, providing a stepping stone to the next stage of Martian exploration.

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.

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.

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.
