Who thrives here Ages 8–17

AstroCamp is built for middle-school campers — an age where leadership tracks, deeper specialization, and identity exploration take over from generalist day-camp formats. stem programs that thrive at this age publish a clear weekly progression rather than a rotating activity menu, and the staff-to-camper conversation usually matters more than the activity list.
