NASA will host an hour-long question-and-answer session through Google+ Hangouts with three astronauts aboard the International Space Station (ISS) on Feb. 22 from 11 a.m. to noon ET.
While NASA will preselect the video questions for astronauts Kevin Ford and Tom Marshburn of NASA and Chris Hadfield of the Canadian Space Agency, it welcomed written questions from Google+, Twitter, and Facebook.
NASA said it will also accept real-time questions that are marked with the #askAstro hashtag on Google+, YouTube and Twitter during the event and that it will open up a thread on its Facebook webpage.
YouTube users can submit video questions tagged with #askAstro by tomorrow, Feb. 12.
NASA has broadcast live onboard many of its space vehicles, with astronauts giving tours of spacecraft and answering questions, but this will be the first time NASA conducts such an event using multiple forms of social media to solicit questions.
