During WWDC, we got a chance to see an upcoming Solar Walk update from the folks at Vito Technology, and that update is now available. It adds a redesigned information screen that's easier to access and more filled out, as well as a greatly improved graphics system. There are also preset bookmarks, which will show you around the solar system from different perspectives. There are a bevy of new objects floating out there in virtual space, including things such as asteroids, comets and dwarf planets.
To celebrate the update and its back-to-school timed release, Solar Walk is currently on sale for 99 cents. This app, like most of Vito's products, has been everywhere already. It's featured in Apple's stores, and chances are you might have already bought it. But if not, at that price, it's a steal.
