I've gotten this question about once a week since Spirit got stuck, but yesterday, two different readers asked the same question within an hour of each other, so I figured it was time for a blog entry.
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."
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.
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?
