When you say NASA, people think Space Shuttle. But NASA does so much more. The agency studies topics ranging from astrophysics to climate change. It also has a new iPad app that details these diverse research projects.

The NASA Visualization Explorer app brings a new topic from the space agency to your iPad each week. It's chock full of images, videos and scientific information. From Polar studies based in Antarctica to the movement of marine deserts, you'll get to see a side of NASA that doesn't often make the front page news. For content and visual appeal, the Visualization Explorer app gets the big thumbs up from us. iPad owners running iOS 4.3 or greater can grab it for free from the App Store.
