Spirit, seen from space

The HiRISE instrument on Mars Reconnaissance Orbiter really is a spy camera in space. Check out this sequence of nine images from the HiRISE archives, which Doug Ellison pulled together into an animation covering more than a year of Spirit's mission. I really wanted to include the whole thing inline in this blog entry but I figured it would be cruel to post a 700k inline image for those of you who have to download my blog entries through the soda straw of a dialup connection.

Spirit explores Home Plate (as seen from space)

More than a year of the Mars Exploration Rover Spirit's examination of the feature in Gusev Crater known as Home Plate is chronicled in this animation of nine images from the HiRISE camera on Mars Reconnaissance Orbiter. The images cover an area approximately 100 meters square. The geometry of Home Plate appears to shift from image to image because the orbiter often had to turn to one side or the other of its orbital track across Mars in order to view Spirit, so usually saw the raised topography of Home Plate from a point that was not directly over Spirit's head. However, some of the apparent shifts in features are also real shifts in the distribution of dust around Home Plate with shifting winds and seasons. The dust storm of summer 2007 almost completely blocks the view of Spirit at one point during the animation. Credit: NASA / JPL / U. Arizona / Doug Ellison Watch the animation a little while and just appreciate the coolness of being able to follow the rover's tracks around the crater. Then think to yourself about how that little moving speck and shadow is a human-built piece of hardware, more than a hundred million kilometers away from us, making a world that's inhospitable to our weak bodies into one we can actively roam, however slowly.
