Dermot O'Leary will be presenting an upcoming documentary transmitted live from the International Space Station (ISS) and Mission Control.
The 'X Factor' host will front the two-hour show, 'Live from Space: Lap of the Planet', which will be broadcast from Houston, Texas, in March 2014, and document the completion of the ISS's entire orbit of the Earth.
David Glover, Head of Specialist Factual at Channel, said: "The ISS is a incredible example of humans working together. To have been granted this access by NASA to the ISS and Mission Control is a true British TV first.
"We hope to show what life on board is really like, what happens when things go wrong and then finally giving viewers a live lap of planet Earth."
The programme is part of Channel 4's 'Live from Space Season', which will also feature two other shows, 'Astronauts: Living in Space' and 'Astronauts: Houston We Have a Problem', and Dermot "can't wait" to present the season.
He said: "It's a big deal for me to be asked to host 'Live from Space Season'. When David (Glover) first told me about the show I had to try hard not to revert back to being the eight-year-old kid and the excitement I felt watching the first space shuttle take off in '81.
"Since then, like most of my 'Star Wars'/Trekkie generation, space has always held a fascination. It's already been an education to research this project and so I can't wait to join the viewers in finding out both the spectacular (and what the astronauts would consider mundane, but most of us will find fascinating) workings of the ISS. I simply can't wait."
Tom Brisley, Creative Director, Arrow Media, added: "'Live from Space Season' takes live event television to a new dimension. Travelling at nearly 300 miles a minute or 17,500 miles per hour, the International Space Station (ISS) makes a complete orbit of the Earth every 90 minutes. In our live two-hour special we will literally take viewers around the world.
"The live visuals, as we look back down to Earth from 250 miles above, will be breathtaking, but these shows will be much more than that. The ISS is the most dangerous place inhabited by mankind, as seen in the fictional Hollywood blockbuster 'Gravity'."
