Angry Birds Space has now been downloaded over 100 million times.

Our back of the envelope calculations say that’s an average of 1.32 million downloads per day, which is quite an achievement. So what’s new in “Angry Birds Space” compared to the original “Angry Birds”? The inclusion of a gravity element, which means you now have to worry about not just how you angle your bird, but also how the pull of nearby planets and asteroids might impact your trajectory. It sounds like a small tweak, but it makes a huge difference. We’re big fans of the video that Rovio made to promote Angry Birds Space because it featured NASA’s Don Pettit lecturing kids about the importance of science. Oh and did we mention that Don was also onboard the International Space Station during the video. That’s bad-ass.
