Today, Wednesday 9/12, NASA will pay tribute to Neil Armstrong and the 50th Anniversary of President Kennedy's "Moon Speech" at 12pm PT / 3pm ET, with NASA astronauts, scientists and engineers coming together in a one-hour Google+ hangout to remember historic NASA innovations and discuss the future goals for scientific discovery and human spaceflight.
Anyone can submit questions before or during the event by using hashtag #askNASA on Google+ or posting questions in the Google+ event.
