近年来,美国快速响应空间系统(ORS)取得了长足发展,先后研制、发射并开展了3颗战术小卫星的在轨演示验证。2011年6月,第一颗快速响应空间系统业务卫星发射升空并已开始业务运行。美国国防部在2011年颁布的《国家安全空间战略》中提出要继续开发ORS能力并使之更加成熟。但在2012年,ORS的发展遭遇波折,美国国防部2013财年军事航天预算申请中提出将关闭2007年成立的快速空间响应办公室。
In recent years, the rapid response space system (ORS) in the United States has made great strides, and successively developed, launched and conducted on-orbit demonstrations of three tactical small satellites. In June 2011, the first rapid response space system operational satellite was launched and commercial operation was started. In its National Security Spatial Strategy promulgated in 2011, the U.S. Department of Defense proposed to continue to develop ORS capabilities and make them more mature. However, in 2012, the development of ORS experienced a series of twists and turns. The U.S. Department of Defense’s fiscal year 2013 military aeronautics and astronautical budget application proposed to close the Rapid Response Office established in 2007.
