KSC dubs the program ATX, but you could call it Space Day Camp. You’ll test simulators of planet rovers, spacewalks, and Mars explorations and try a mock-up of a launch. Nothing is as intense as what astronauts experience, but this 5-hour session is still plenty rigorous for most terrestrials, and the facilitators can answer nearly any question you can launch at them. You can also book one-off time slots on the “Training Stages” Spacewalk Stage and Mars Exploration simulators for $30–$40. For something brainier, the Mars Base 1 program ($150; 7 hrs. including lunch; ages 10 and older) casts your kids as true scientists running a research center on the Red Planet, doing tasks from collecting plants to programming drones.
