I'm Marty McGuire: NASA Solar System Ambassador, amateur astronomer and lifelong aeronautical & space enthusiast in Bethlehem, Pennsylvania. I can be found on social media as “Backyard Astronomy Guy” and I've participated in NASA Social Media events at NASA Headquarters, NASA Kennedy Space Center, NASA Goddard Space Flight Center and NASA Wallops Flight Facility. I enjoy staying current with developments in human spaceflight, robotic solar system exploration and deep space telescope missions.
