（原标题：引力一号实现第二次海上发射，中国星链冲刺提速） 21世纪经济报道记者 彭新 东方空间总经理彭昊旻此前接受媒体采访时提及，比起目前国内主流火箭，引力一号发射成本已降低 30-40%。东方空间还称，作为目前投入运营的运力最大的火箭，引力一号率先满足我国规模化低轨星 座组网发射需求。 目前，我国低轨星座组网已进入密集部署窗口期。2024年中国完成68次轨道发射。进入2025年，根据泰 伯智库发布的2025年上半年中国商业航天产业进展数据年报，截至今年6月，我国完成35次火箭发射任 务，在下半年，卫星组网频率进一步加快。但与低轨星座批量上天的节奏相比，运力与组织仍需扩容与 提效，呈现"星多箭少"供需现状。 值得一提的是，东方空间正在加速研制"引力二号"大型液氧煤油火箭，目前已完成方案设计。相比"引 力一号"，"引力二号"具有运载能力大、性价比高等特点，其运载能力进一步提高至15吨（500千米太阳 同步轨道），可携带30颗500公斤重的卫星上天，同时将成本进一步降低。 其中，支撑"引力二号"的"原力-110"百吨级液氧煤油发动机，海平面推力达110吨，是当前中国商业航 天领域推力最大的液体火箭发动机，也是"引 ...
