AerospaceFest is the Discovery Center’s free, family friendly annual celebration of all things STEM. Taking place on the third Saturday in September, this event brings together science and education organizations from around the New England area to share their work with our visitors through demonstrations, hands-on activities, and discussion. The day also features the premiere of a new planetarium show, a keynote presentation by retired NASA Astronaut Dottie Metcalf-Lindenburger, and the presentation of the Alex Higgins Memorial Space Camp Scholarship, which provides three New Hampshire students the opportunity to attend U.S. Space Camp.
