当前空间工业界必须应付的主要问题是航天器的高发射成本。为更好地开发空间,发射成本必须大幅度降低。解决这个问题的办法之一是采用廉价的、可重复使用的发射器。关于这一点当前正在进行多方面的研究,其中也包括了对更小的“轻卫星”的设计研究。目前比较新的微机电(包括微机械、微敏感器、微执行机构和嵌入电子元器件)领域有可能压缩各类空间任务,明显降低整个系统的 The main issue that the current space industry has to deal with is the high launch cost of the spacecraft. In order to better develop the space, launch costs must be significantly reduced. One solution to this problem is to use cheap, reusable launchers. Much research is ongoing on this point, including the design of smaller “light satellites.” The relatively new fields of MEMS (including micromechanics, micro-sensors, micro-actuators and embedded electronics) are likely to compress various types of space tasks, significantly reducing the overall system
