The Hangout will take place from 11 am to 12 pm EST on February 22. The event will allow NASA fans to interact with astronauts both on Earth and aboard the ISS. Astronauts Kevin Ford, Chris Hadfield, and Tom Marshburn will be on-hand to answer questions about life on the ISS.
Since only up to 10 people can "Hangout" at one time (though the event will be open for anyone to watch live), NASA is encouraging its social media fans to submit video questions before the Hangout. During the Hangout "several" of these video questions will be chosen to be aired and answered by the ISS station crew and other astronauts. The videos must be uploaded to YouTube with the tag #askAstro and must be 30 seconds or shorter. The deadline for submitting videos is February 12.
NASA will also take live questions from its social media feeds on Facebook, Twitter, and Google+ during the Hangout. The same hashtag, #askAstro, will be used to identify questions during the Hangout. The agency stated that "unique and original questions" are more likely to be answered.
Though this is the first NASA Hangout from the ISS, it won't be the last. The agency has stated that it will continue to host Hangouts "with astronauts on the ground and in space, scientists, engineers, and managers on the agency's missions and milestones."
