A Martian Stares Back

There is nothing particularly scientific about this image, but it is remarkably evocative. The Curiosity rover on Mars took a self-portrait of its primary camera masthead using another camera (the rather charmingly named "Mars Hand Lens Imager" or MAHLI) mounted on its robotic arm on Sept 7th 2012. In part the image was made to test the functioning of a transparent dust cover on MAHLI, and this cover is in place here - creating a rather artistic fogginess to the image.

It was only polite for the main Mastcam on Curiosity to take a picture of MAHLI as well, which it actually did the day before. To quote from the Mars Science Laboratory website "The reddish circle near the center of the Mastcam Sol 30 image is the window of MAHLI's dust cover, with a diameter a little less than a soda can's diameter. Inside the lens, each of the nine glass lens elements and the front sapphire window are bonded or cemented in place by a red-colored silicone RTV (room temperature vulcanizing) material. This is a space-qualified "glue" that holds the lens elements in place. When the MAHLI is viewed from certain angles, this material gives one the impression that the inside of the lens is red."

So there you have it - a multi-eyed, recent martian immigrant, staring back at itself.
