远方的发射塔像是一根静默的银针,矗立在天地交界的旷野上。这是肯尼迪航天中心到访者对 太空探索公司(SpaceX)使用的卡纳维拉尔角40号航天发射复合体(SLC-40)最深刻的印 象。 SLC-40属于美国"东部发射场",同时被泻湖与大西洋紧紧包围。它位于佛罗里达州的梅里特 岛,是火箭借助地球自转飞向赤道轨道的理想出发点。这里气候常年温和,鲜有严寒,有利于 维持高密度的发射节奏。 在SpaceX从美国政府租赁的三个发射场中,由SLC-40承担的发射任务最多且密集:2024年, SLC-40共发射了62枚猎鹰9号火箭,平均每6天发射一枚,几乎占SpaceX全年发射总量的 45%。同年,用于发射"星链"(Starlink)卫星专用任务又占据了猎鹰火箭发射任务总数的三 分之二。 "星链"是SpaceX在2015年提出的低轨卫星互联网星座计划,其原理是让低轨道卫星充当空中 中继,转发无线电信号,实现了无死角的信号覆盖。对于"星链",SpaceX创始人埃隆·马斯克 对它有宏大的计划。 事实上,SpaceX正领跑全球低轨卫星互联网市场,据21世纪经济报道记者统计,截至2025年8 月19日,SpaceX已经进行超过290次 ...
