My inbox was exploding this morning with messages about a tremendously cool animation released this morning by ESA's Mars Express team. It shows Phobos crossing Deimos, in what's known as a "mutual event."
The Mars Exploration Rovers managed to make history and uncover history in November and that put both Spirit and Opportunity in the planetary exploration spotlight during the 71st month of an overland expedition that was supposed to be a three-month tour.
I probably crammed too much into today's class: an hour-and-a-half whirlwind tour through the cameras on the rovers and Cassini, how to access their raw images on the Internet, and some basic processing that you can do with each of them.
Since tomorrow's class is going to be on playing with raw images from the rovers and Cassini, I've been playing with recent raw images from the rovers and Cassini! I just thought I'd share a couple of the fun items I've been working with.
Even though all of us rover fans know that Spirit is really, really stuck, I think I'm not the only one who was secretly hoping that today's images downlinked from Spirit would show that the rover had magically popped out of the ground overnight. Of course, she didn't.
Since A. J. S. Rayl was also listening in on today's press briefing about the efforts to extricate Spirit from her predicament at Troy, I'll just hit the high points and send you over to her story when she has posted it.
On Monday, November 16, 2009, Mars Exploration Rover Spirit will begin the much-anticipated, weeks-long process of extricating itself from a patch of powdery soil that stopped it in its tracks six months ago. It will begin by driving forward to the north, following its tracks out, even though its right front wheel is broken and immobilized.
The Mars Exploration Rover Opportunity has been studying a lot of meteorites. That made me wonder, why study meteorites on Mars when we can study them in hand on Earth? How are Mars meteorites interesting?
The Mars Exploration Rover mission logged another textbook-rewriting month in October 2009 with more discoveries of geologic gems, new robot achievements balanced with equal amounts of challenges and frustrations overcome, topped off with special honors.
I wonder if this came from the same original body as Block Island, or if Meridiani is the kind of slowly deflating landscape that accumulates meteorites at its surface, like the ANSMET meteorite hunting spots in Antarctica?
From notable achievements and new discoveries to trials and tribulations and harbingers of hope, the Mars Exploration Rovers seemed to experience the gamut on the Red Planet this September, their 69th month on an expedition that originally set out back in 2004 for a three-month tour.
Doug Ellison has done it again: he's created a spectacular overflight of Gusev crater based upon digital elevation models of the terrain produced by the United States Geological Survey from HiRISE data.
For a while, Mars was beating Spirit while she was down, throwing a dust storm at the rover where it's bogged up to its hubcaps in fluffy soil When lots of dust is lofted into the sky, the hazard is that when it comes down, it may come down on the rover and its solar panels. But it appears things on Spirit are still pretty clean.
