Astronaut training facility tour
Have you ever wondered how astronauts train for microgravity?
Hop on a tour and take a ride to NASA’s Neutral Buoyancy Laboratory (NBL) and see how astronauts train underwater to prepare for challenges in low Earth orbit March 9-16. The NBL is a 6.2-million-gallon diving tank where astronauts perform simulated extravehicular (spacewalk) tasks.
NBL tours are $12.95 per visitor and must be purchased in addition to your general admission ticket. Tickets can be purchased online or in person at the Guest Services Desk. Space is limited. Please note the tour visits a working government facility which is subject to availability and can temporarily close to visitors without notice. Tours will leave at approximately the scheduled departure time.
