In this pioneering two-and-a-half-hour live broadcast from the International Space Station and Mission Control in Houston, viewers were able to interact with the astronauts onboard the International Space Station 250 miles above Earth as they traveled around the planet in 90 minutes, at speeds of up to 17,500 mph. The astronauts shared their breathtaking views of Earth, with live links to English-speaking astronauts Rick Mastracchio and Koichi Wakata. On the ground, Dermot O’Leary and space veteran Mike Massimino – one of the astronauts who helped repair and upgrade the Hubble Telescope – were at the heart of Mission Control with the team who hold Rick and Koichi’s lives in their hands. Also taking part was Professor Stephen Hawking and British astronaut Tim Peake, who is set to join the crew onboard the International Space Station in 2015.
