Tell the nation why space matters to our future! The Coalition for Space Exploration, in partnership with the NASA Visitor Centers Consortium has launched the “Why Space Matters to the Future” video contest encouraging U.S. residents to visualize what life will be like in 10, 25, or 50 years if the boundaries of space continue to expand. Entrants can submit a short video capturing their vision of why exploring space matters and how it will benefit future generations. Three winners will receive a VIP trip to one of three NASA’s visitor centers: Kennedy Space Center Visitor Complex in Florida, the U.S. Space and Rocket Center in Alabama or Space Center Houston in Texas. Winning videos will be shared with the public and national leaders. The contest submission period ends on April 7. Get more details here.
