Focusing on the extraterrestrial all day can probably make it pretty easy to forget about all that's going on here on Earth. NASA has shifted its focus a bit for its new iPad app, taking a look at the goings-on of the world around us. The app features videos, stories, and images explaining things like climate change and plant life from the vantage point of the organization's satellites. Like the self-titled NASA iPad app before it, the Visualization Explorer is available now as a free download from iTunes.
