《科创板日报》12月22日讯（编辑 宋子乔）美股商业航天股周五集体大涨，Rocket Lab Corp（火箭实 验室）涨17.69%，AST SpaceMobile Inc-A涨15.03%，维珍银河涨6.71%。 带头领涨的火箭实验室为目前唯一成功实现轨道级发射并上市的"第二梯队"领头羊，刚获得来自美国太 空发展局（SDA）的巨额订单，也是其自身历史上最大的订单。 据美国《空天部队》杂志网站报道，当地时间12月19日（周五），美国太空军下属的美国太空发展局宣 布，向4家公司授予价值35亿美元的合同，用于采购总共72颗导弹预警和跟踪卫星——这是迄今为止美 军低地球轨道星座的最大一笔交易。 美国太空发展代理主任古尔帕塔普•桑杜在一份声明中表示，第三批卫星将"显著扩大"SDA的覆盖范 围，并提高其跟踪星座的精度，"这些卫星的加入将实现近乎连续的全球导弹预警和跟踪覆盖，以及能 够生成用于导弹防御的火控级跟踪的有效载荷。" 上述4家公司分别是洛克希德•马丁、诺斯罗普•格鲁曼、L3哈里斯和火箭实验室，它们将在未来3年内为 美国太空发展局各生产18颗卫星。由于各公司提供的卫星产品略有不同，相应的合同金额有差别： 洛克希德 ...

美国太空发展局正在构建其"扩散型太空作战架构"(PWSA)，这是一个由近地轨道数据传输卫星、导弹 预警和防御卫星组成的星座。目前，该机构已在轨部署了8颗导弹预警与跟踪卫星，以及19颗数据传输 卫星，作为其"第0批次"试验性星座的一部分。同时，该机构正开展一项为期10个月的发射行动，计划 再发射28颗导弹预警与跟踪卫星和126颗通信卫星，组成"第1批次"。 美媒称，导弹预警、跟踪和防御是三个相互关联又各自独立的任务。导弹预警传感器会在导弹发射后向 用户发出警报。导弹跟踪系统会跟踪导弹的飞行轨迹。导弹防御传感器则提供拦截导弹所需的必要数 据。 来源：格隆汇 据美国《空天部队》杂志网站12月19日称，美国太空军下属的太空发展局当天宣布，向4家公司授予价 值35亿美元的合同，用于采购总共72颗导弹预警和跟踪卫星——这是迄今为止美军低地球轨道星座的最 大一笔交易。 太空发展局宣布，洛克希德·马丁公司、诺斯罗普·格鲁曼公司、L3哈里斯公司和火箭实验室公司将在未 来3年内为其导弹跟踪卫星群的第三批订单各生产18颗卫星。 各公司提供的卫星有效载荷略有不同：洛克希德·马丁公司获得了一份价值11亿美元的合同，用于生产 导弹预警、 ...
