The latest issue of Sky and Telescope hit the stands a few days ago, with all the usual goodies and one not so usual. The cover article is called Uncovering Mars’s Secret Past, and to go with it they include a nifty little DVD with over 500 images and videos from the Mars Rovers cameras. You can also buy the Mars DVD separately, but for fifty cents more you get the July volume of the magazine along with the free DVD. The disk was put together by Dr Jim Bell, Lead Scientist for the Mars Rover’s panoramic cameras. NASA is building its own cloud environment, called Nebulous (I can’t prove it, but I suspect pun intended). This is for outreach and education, amongst other things, and is compatible with the Amazon web services platform.
