Opportunity must be driving down Meteorite Alley on Mars. The rover has come across still another meteorite, the third space rock it has found the past few months, and fourth overall since 2005. This one is called Mackinac, which continues the “island” theme by which the science team has dubbed the meteorites. Block Island was found in July 2009, and Opportunity came upon Shelter Island the end of September (around sol 2020 for the rover). Mackinac was found on sol 2034 (Oct 13), and it looks very similar in composition to the two earlier meteorites. Opportunity analyzed the Block Island and found it was made of iron and nickel.

The image above was color calibrated by Stu Atkinson, who hangs out at UnmannedSpaceflight.com. You can find all the raw images Opportunity has sent back to Earth here, and raw images from Spirit here. But you can also follow Opportunity in other ways….

You can keep track of Opportunity’s travels through Meridiani Planum on its way to Endeavour Crater at one of Stu’s blogs, Road to Endeavour. But — and this is very fun — you can also follow Oppy on Google Mars, and see where it has found the meteorites. Tesheiner on UMSF regularly updates a route map, pinpointing the spots where the rover stops. Just go to Google Mars (download Google Earth and Mars here if you don’t have it yet), open up Google Mars, then click on this link, download and open, and you’ll be transported to Opportunity’s location on Mars. Extreme, extreme cool.

Now, you’ll notice that region of Google Mars doesn’t have high-resolution imagery yet. They’re working on it. In the meantime, though, if you want to see a great mosaic of the terrain that Opportunity is traveling through, check out this image below created by Ken Kremer, also of UMSF. This is from Sol 2010 showing Nereus Crater and dunes on the Road to Endeavour, where Oppy was just prior to discovering Shelter Island. The crater is about 10 meters across. Ken created this mosaic from raw images from the Cornell Pancam raw images, stitching multiple images together and calibrating the color. Beautiful!

Thanks to Stu, Tesheiner and Ken for sharing their incredible Martian handiwork!
