In a first for the agency, NASA will host a Google+ Hangout live with the International Space Station between 11 a.m. to noon EST on February 22. Google+ Hangouts allow people to chat face-to-face while thousands more can tune in to watch the conversation live on Google+.
Although the deadline to submit video questions was February 12 you will be able to watch replies to selected questions. Several video questions will be selected and answered by astronauts on the space station and on the ground. Additionally, NASA will ask real-time questions submitted by followers on Google+, Twitter, and Facebook.
Information on this Hangout and future sessions can be found at: http://www.nasa.gov/connect/hangout.html
