By Sol 3325 Opportunity has driven up onto the next "island" of rock, "Sutherland Point" and "Nobbys Head." On this sol Opportunity is only about 700 m from the goal, the mountains to the south.
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.
Analysis of the House Science Committee Hearing on the 2013 NASA Authorization Bill
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.
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!
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!
This week's "lizard" or "rat" on Mars is just the latest of a never-ending stream of so-called discoveries of animate and inanimate objects in images returned from the Red Planet. I challenge you readers to find more such objects in one Curiosity panorama.
Nothing reflects the romance of deep space exploration more than the evocative names of places on the planets and moons.
For most of April, while Mars scuttled behind the Sun as seen from Earth, both Mars rovers were pretty inactive. Now that conjunction has ended, both are doing what rovers should be doing: roving and exploring. As of sol 3312 Opportunity had moved more than 300 meters southward toward Solander Point, while on her sol 279 Curiosity drilled at a second site, Cumberland.
Mars gives up its secrets through the unseen colors of its rocks.

Thursday, May 9th, at noon PDT/3pm EDT/1900h UTC, we are joined by Emily Dean, who works on the camera team for the Opportunity rover on Mars.
A recently published paper proposes that much of the sedimentary rock on Mars formed during rare, brief periods of very slight wetness under melting snow.
