SpaceX 周五完成首批第三代 Starlink 卫星部署。这是其原型火箭 Starship 升级版的第 13 次试飞,也是 V3 版本首次把新一代星链卫星送入预定释放流程。不过,执行回收任务的 Super Heavy 助推器在模拟海上着陆时再次出现故障。

助推器在着陆阶段失效

按计划,助推器应在墨西哥湾进行一次模拟着陆。飞行过程中,它比上一次测试走得更远,但在着陆点火阶段,未能正常启动所需全部发动机。随后,助推器以高于预期的速度撞击海面并发生爆炸。

这已是 V3 版 Starship 第二次出现 Super Heavy 相关问题。5 月的首次 V3 飞行中,助推器曾在与上面级分离时发生故障。

一周前曾因发动机问题中止

这次发射距离上一次尝试仅过去一周多。此前,SpaceX 在点火后不久因多台发动机失效而立即中止发射。公司称,已在本次飞行前更换 6 台发动机,以解决当时暴露的问题。

从结果看,助推器本次飞行表现较前次有所改善,但仍未完成完整回收流程。相比之下,上面级表现更稳定。5 月那次 V3 首飞中,上面级曾损失一台发动机,而这次飞行中未再出现同类问题,并顺利完成星链卫星释放。

新卫星仍不会进入最终轨道

不过,这批第三代 Starlink 卫星并不会长期留在太空。由于 Starship 目前仍无法进入地球轨道,这些卫星预计会在释放约 20 分钟后进入大气层烧毁。

这意味着,此次任务更接近一次系统验证,而非正式的在轨组网部署。对 SpaceX 来说,重点仍是验证 V3 版本在发射、分离和载荷释放等环节的稳定性。

上市后首次试飞牵动股价

这是 SpaceX 6 月上市以来的首次 Starship 发射。公司上市后股价整体走弱,已从每股超过 200 美元的高点回落至周五收盘时的 115 美元。

在此次助推器故障发生后,SpaceX 股价盘后一度下跌约 2%,随后收窄部分跌幅。此前一周,因发射在点火后即告中止,公司股价也曾在次日承压。

市场正在观察 SpaceX 一贯采用的“边飞边修”开发方式,能否在 Starship V3 阶段更快转化为稳定的测试结果。对这家公司而言,后续试飞节奏和回收成功率,将直接影响外界对其重型运载与星链扩展计划的判断。
