• 15．Find Your Adventure at the Space and Aviation（航空） Center If you're looking for a unique adventure，the Space and Aviation Center（SAC） is the place to be.The Center offers programs designed to challenge and inspire with hands-on tasks and lots of fun.
     More than 750，000 have graduated from SAC，with many seeking employment in engineering，aviation，education，medicine and a wide variety of other professions.They come to camp，wanting to know what it is like to be an astronaut or a pilot，and they leave with real-world applications for what they're studying in the classroom.
     For the trainees，the programs also offer a great way to earn merit badges（榮譽(yù)徽章）.At Space Camp，trainees can earn their Space Exploration badge as they build and fire model rockets，learn about space tasks and try simulated（模擬的） flying to space with the crew from all over the world.The Aviation Challenge program gives trainees the chance to earn their Aviation badge.They learn the principles of flight and test their operating skills in the cockpit（駕駛艙） of a variety of flight simulators.Trainees also get a good start on their Wilderness Survival badge as they learn about water-and land-survival through designed tasks and their search and rescue of "downed" pilot.
     With all the programs，teamwork is key as trainees learn the importance of leadership and being part of a bigger task.
     All this fun is available for ages 9 to 18.Families can enjoy the experience together，too，with Family Camp programs for families with children as young as 7.
     Stay an hour or stay a week—there is something here for everyone!
