导语：在国内已成立数十家商业火箭公司的背景下，对于技术研发和规模生产节奏的把握，或初步划分 出市场格局。 商业航天是近期最热门的新兴行业之一。不同于一些存在不确定性的新兴行业，商业航天的短中期前景 清晰可见：规模达数万颗卫星的星座将在太空中组建卫星互联网，成为未来通信、计算、感知的重要基 建。美国商业航天巨头SpaceX的"星链"星座已发射超1万颗卫星，并已走上盈利道路。 从卫星制造、发射、组网到卫星应用，商业航天具有万亿元市场规模，但当前其堵点也显而易见：卫星 亟待发射，火箭运力严重不足，我国商业火箭公司尚没有一款大运力、低成本、高可靠的火箭。 临近年末，我国新一代商业火箭即将首发。这批火箭都定位为大型液体可复用火箭，旨在服务卫星互联 网组网发射。可复用是降低发射成本的关键技术之一，其进展在行业内外备受关注。不过，上海证券报 记者采访专家及业内投资人士了解到，通过回收复用降低成本，并不能通过单次技术突破实现，而是经 过持续验证后，通过高频次发射才能实现的结果。对于组网的迫切需求，在循序渐进攻克可复用技术的 同时，进行规模化生产、提高火箭可靠性是当下更务实的选择。 大量卫星亟待发射凸显火箭运力不足 卫星互联网 ...
