These events are targeted at the social media followers of NASA through platforms such as Twitter, Facebook, Google Plus, Instagram, YouTube and more.
The length of socials range from a few hours to a couple days to much longer in the case of some events, such as the STS-133 launch tweetup.
Notable speakers include NASA Administrator Charles Bolden, SpaceX President Gwynne Shotwell, Senator and astronaut John Glenn, Bill Nye, and final Space Shuttle crew members Sandy Magnus and Chris Ferguson.
