"Small-scale satellites have become the focus of development in many countries in recent years. This is because they are small, light and cheap, making them faster to develop than medium and large satellites, and allowing the development of more diverse space programs," points out Chang.
「小衛星近年來成為各國發展重點，原因是它體積小、重量輕、成本低，研發的時間也比中、大型衛星為短，可以做更多元化的太空發展。」
