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?
These Mars Reconnaissance Orbiter HiRISE images of the defunct Phoenix lander in the early dawn light of northern spring have been out for some time, but no one had accomplished the difficult task of locating the Phoenix hardware in them until this week.
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?
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.
