US deep space organisation NASA is hosting a first-of-its-kind interactive session with astronauts aboard the International Space Station (ISS), orbiting over 200 miles above the Earth's surface.

The session will be on Google+ Hangout and it starts on Friday, at 10.30am EDT (2.30pm GMT). It will run for about an hour and will allow people on Earth the rare chance to have a face-to-face conversation with people in outer space.

According to NASA, there are six astronauts aboard the station and they are led by Commander Kevin Ford, who will remain in space till March 2013. At that point, Ford and Flight Engineers Oleg Novitiskiy and Evgeny Tarelkin will complete their stint and Chris Hadfield will assume command. Incidentally, when he does, Hadfield becomes the first Canadian to take command of the ISS. Flight Engineers Tom Marshburn and Roman Romanenko complete the crew.

The live event will feature Ford and Marshburn (@AstroMarshburn), as well Hadfield (@Cmdr_Hadfield).

Where to Watch Live

The event can be viewed live on NASA's Google+ page as well as their YouTube channel. A list of questions has already been received from around the world but more questions will be accepted - through Google+, Twitter (#askAstro) and Facebook.
