Today NASA launched a suborbital rocket, but had to shoot it out of the sky due to alleged "launch failure. 很少被提起的关于全球变暖的事实：它使地球所有人烟稀少的地区变成人间天堂。
In the meantime, Lockheed Martin managers are focusing on suborbital sounding rockets for hybrid motors. 在此同时，洛克希德马丁公司的人员正致力研究供次轨道探空火箭使用的混合型马达。
In addition to orbital trips, Space Adventures says it is developing a programme to take passengers on suborbital flights starting in 2007. 现下正在开发的一项工程是让旅客离开地球轨道的束缚而进行轨道外的飞行，这个项目大概会在2007年完成。
Could this actually be an effort to discourage suborbital rockets, which might break through the space debris and catch sight of the Universe society? 这有可能是为了抵制亚轨道火箭的一种手段么？因为它将冲破太空垃圾构成的天然屏障而将外部宇宙大社会的芳容尽收眼底。
Another unconventional design element, the hybrid rocket engine that powers the suborbital vehicle, provides unique operational options. 另一个异于传统的设计要素，是提供次轨道载具动力的混合式火箭引擎，它能提供独特的操作选择。
