Keeping up with Curiosity, almost a year after landing
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.
Happy 32! Happy New Mars Year!
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.
Terra Cognita
Pushing back the frontier, and filling in the blank spaces on the map.
The Mars 2020 Rover In-Depth
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.
Field Report From Mars: Sol 3378 - July 25, 2013
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.

A new HiRISE view of Opportunity (sol 3361)
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.
Dunes on Tatooine
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.
Programmable Mars Watch for $50
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 Ice Pits of Mars
The south polar cap of Mars is riddled with strange landscapes.
Mars Exploration Rovers Mission Update: Opportunity Continues Sprint to Solander Point
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.
Stationkeeping in Mars orbit
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.
If we started today, how long would it take to get to Mars? With this budget, never.
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.
Enormously detailed photo of Kasei Valles from Mars Express
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.
Exploring Ten Years' Worth of Mars Express Data
Mars Express has been in flight for a decade, more than enough time to send home some amazing finds.
Pretty pictures: Curiosity working late
Just some cool photos of Curiosity lighting up the Cumberland drill hole after sunset for a little nighttime science work.
Curiosity update, sol 295: "Hitting the road" to Mount Sharp
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!
Mars Exploration Rovers Update: Opportunity Departs Cape York, Breaks Apollo Record
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.
One Ocean World Among Many
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!
