Early missions like Explorer 6 pushed the boundaries of what was defined as possible. Only 10 years later, history was made when humans took the first steps on the Moon. On this journey, we have also learned more about Earth. Explorer 6 gave us one of the first views at the small, blue planet we know as home. During your visit, be sure to walk through the Rocket Garden and stop in to our Heroes and Legends attraction, which honors the early space program and those first steps into the unknown.
