Astronaut Tom Marshburn on his very first spacewalk in 2009.
Want to have a chat with some astronauts while they're in space? There's a G+ hangout happening this week.
NASA and the International Space Station (ISS) have been doing some really interesting work on social media. Earlier this week, commander Chris Hadfield (who uses his Twitter feed to post gorgeous photos of the Earth from aboard the ISS) so that people on the ground could learn about life in space.
Now you can hang out with three of the ISS astronauts on Google+ on Friday, 22 February at 3am (AEDST) — that is, if you don't have to worry about work the next day. Commander Hadfield and astronauts Kevin Ford and Tom Marshburn will be on NASA's Google+ to answer questions about space, the ISS and everything in between.
To submit questions in real time during the event, you can use the Google+ page, NASA's Twitter or NASA's Facebook page (which will start accepting questions the morning of the event) using the hashtag #askAstro.
And if you want to see the ISS in the sky, don't forget to sign up to.
If you miss it, don't worry too much: the hangout will later be uploaded to NASA's YouTube channel for the latecomers.
