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.
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.
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.
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.
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.
Planetary Society Hangout: A Day in the Life of the Opportunity Rover with Emily Dean
Thursday, May 9, at noon PDT/1900h UTC
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.
As the Mars Exploration Rover (MER) team waited out solar conjunction, Opportunity spent most of April atop the western rim of Endeavour Crater, conducting a chemical analysis of an ancient waterborne vein on Matijevic Hill. It was by the book until the last week of the month when the robot field geologist suffered an electronic "hiccup" known as a warm re-boot, and went into auto mode, a kind of safe mode when something doesn't go right.
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.
