It’s Earth Day today (didn’t you see the Google logo?), so enjoy NASA’s HD video of views of our beautiful planet from the International Space Station. According to NASA, the ISS travels at an approximate speed of 17,500 miles per hour, orbiting Earth every 90 minutes from an altitude of approximately 220 miles. Also interesting to note is that the ISS is big enough to see from Earth with the naked eye.
