The informal learning environment of the Museum of Science Fiction's "Escape Velocity" event offers an integration of science and science fiction in a variety of activities, talks, events, exhibits, and panels to further attendees' interest. This study examined the efficacy of this event as a learning experience through a survey of attendees. Attendees reported increasing their knowledge of STEM, being able to join many STEM activities, feeling empowered to connect with NASA scientists and resources, intending to look for ways to find out more, and wanting to learn more about NASA science. Those who attended NASA-related panels reported statistically significant gains in knowledge and interest as a result of attending panels on Habitable Worlds, Apollo 50th Anniversary, and Weather on Earth/Weather in Space.
