American kids go to a space camp during the summer holidays. They learn how to operate the Space Shuttle. A team consisting of a guy who just entered to meet girls, a wanna be astronaut and an instructor who wanted to go on a mission instead of teaching can sit in the Shuttle while testing the engines. Then they're launched by mistake ... 描述一群青少年学生参加美国太空总署主办的太空夏令营，亲身体验太空登月的操作环境。不料在一次意外中，他们乘坐的太空舱竟然真地发射升空，几个年轻人登时六神无主，幸好有一个机器人留在舱中协助他们化险为夷。在众多的太空科幻片中，哈瑞．温勒导演本片较著重太空知识的传递而非眩目迷人的特效。外景在NASA 实地拍摄，有些地方颇令人大开眼界。凯特．卡普肖饰演女教官、利．汤普森、凯利．普雷斯顿饰演太空历险的学生，但最讨人喜欢的还是那个造型和表演都相当有趣的机器人。
