空间科学主要是基于航天器平台获取实验数据、实现科学发现的重大前沿基础研究。中国实施了"悟空""慧眼"等一批较大的科学卫星任务。阐述了国际上重要科学发现和成果，提出当前国际上已认识到立方星在空间探索与发现中的重要作用；总结了美欧等航天强国和机构已实施和论证的若干立方星科学探测计划及取得的有影响力的原创科学成果，以及中国立方星技术演示验证和商业航天已取得的进展；提出了中国空间科学界应进一步关注立方星的发展，利用立方星平台开展研究，与传统大中型空间科学卫星形成互补，增强并拓展相关领域的探测能力，有效降低任务难度并缩短研制周期，促进中国空间科学取得更多重大发现和突破。
Space science encompasses all major frontier basic researches that base on spacecraft platforms to obtain experimental data and realize scientific discoveries. China has started to develop scientific satellites such as DAMPE, HXMT. The international scientific community has recognized CubeSats to have important effect on deep space exploration. The occident and institutions support CubeSat's scientific research, and have implemented some missions. Significant progress of CubeSat platform has also been made in China's commercial space and space technology demonstrations, which has laid an important foundation for scientists to make breakthroughs in space science.
