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.
The International Association of Geomorphologists' "planetary geomorphology image of the month," contributed by Joe Levy, features water tracks on Earth and compares them to recurring slope lineae on Mars.
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.
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!
