NASA has an app. That filled us with excitement, anything NASA does is awesome and awakens the inner child – but this is only for Android-owning big kids. Look into space at any time of day or night using live streamed video, or a huge archive of mission footage. Galleries of images and cool countdown clocks all make up for the less than great design. Thankfully for the astronauts, NASA's engineers are more about function than beautiful form – but never mind, it's a great free app.
