Some of humankind’s greatest adventures began here at NASA’s launch headquarters, an easy hour east of Orlando on the Atlantic coast. Time your visit right, and you may see a space shuttle streak into the sky on liftoff (visible all around the state but much better from up close). Attractions include Q&A’s with astronauts, plain-speaking technical explanations, and a launch-simulation ride.
Tip: Getting around the center requires taking on-site buses, and the last one sets out around the property between 2 and 3 p.m. Arrive early in the morning to give yourself plenty of time.
