NASA astronaut Mark Polansky, who will be commanding the next mission to the International Space Station, has just posted a video to NASA’s official YouTube channel inviting YouTubers and Twitter fans to take part in his next mission, submitting video questions via YouTube and following mission updates over Twitter.
To ask a question, Polansky says to create a video of around thirty seconds and post it to YouTube, then send it to his Twitter account using an @reply. He’ll respond to the questions on NASA TV, which is broadcast nation-wide. (Source)
I encourage you and your students to participate in this activity. It’s a rare opportunity. Who knows? You may have a future NASA astronaut, controller or engineer sitting in your class!
