SpaceX完成星舰V2测试,推进V3开发

摘要

SpaceX已完成星舰V2的最终试飞,达成关键目标,为下一代V3原型铺平道路。

SpaceX成功完成了星舰V2的最终试飞,标志着该航天器开发的一个重要里程碑。这枚近400英尺高的火箭于当地时间下午6:23从德克萨斯州星基地发射升空。超级重型助推器为3月测试中重复使用的型号,执行了新的着陆点火方案,先点燃13台发动机,然后逐步减至5台,最终3台发动机维持最后的悬停,约在发射后7分钟内按计划在墨西哥湾实现软溅落。

同时,星舰的上级阶段释放了8个模拟星链卫星,用以测试一种新的“动态倾斜机动”方案,旨在未来星基地的返航着陆尝试。上级阶段随后在印度洋溅落。此次飞行是第二代星舰和第一代超级重型助推器的最后一次发射。工程师们还对上级阶段的热防护瓦进行了实验,包括选择性拆除和新型瓦片变体,以收集再入数据。

SpaceX复制了第10次飞行的其他关键里程碑:部署模拟器并在轨点火星舰的六台猛禽发动机之一。此次测试正式开启了项目的下一阶段:飞行升级版原型V3,该版本配备轨道对接和推进剂转移演示功能,这些能力对月球和火星任务至关重要。V3还包括结构改进和猛禽发动机升级,旨在提升载重能力,具体数据未予披露。

“下一代型号将用于首批星舰轨道飞行、运营载荷任务、推进剂转移等,我们将持续迭代,打造一款完全且快速可重复使用的航天器,服务于地球轨道、月球、火星及更远的空间,”公司声明中表示。

与此同时,SpaceX正在升级星基地的A发射台,并将发射活动转移至B发射台。公司还计划在佛罗里达的卡纳维拉尔角和肯尼迪航天中心建造双星舰发射台。星舰是迄今为止开发的最强大火箭,是NASA阿尔忒弥斯计划和SpaceX部署更大容量星链卫星计划的基石。

代理NASA局长肖恩·达菲在X平台上称赞此次任务,表示这是“向将美国人送上月球南极迈出的又一重大步伐”。

事实核查

使用外部来源和数据库核实文章的事实。

✓
Confirmed

SpaceX has successfully completed the final test flight of its Starship V2, marking a significant milestone in the spacecraft's development.

✓
Confirmed

The nearly 400-foot-tall rocket lifted off from Starbase, Texas, at 6:23 PM local time.

✓
Confirmed

The Super Heavy booster, reused from a March test, executed a new landing-burn profile, reigniting 13 engines before throttling down to five, and finally three for the final hover, culminating in a planned soft splashdown in the Gulf of Mexico approximately seven minutes after liftoff.

✓
Confirmed

Concurrently, Starship's upper stage deployed eight mock Starlink satellite simulators, testing a new 'dynamic banking maneuver' profile intended for future return-to-pad attempts at Starbase.

✓
Confirmed

The upper stage then splashed down in the Indian Ocean.

✓
Confirmed

This flight marked the final launch of the second-generation Starship and the first-generation Super Heavy variants.

✓
Confirmed

Engineers also experimented with the heat shield tiles on the upper stage, including selective removals and novel tile variations to gather reentry data.

✓
Confirmed

This test formally initiates the program's next phase: flying an upgraded prototype called V3, outfitted for in-orbit docking and propellant-transfer demonstrations, capabilities essential for missions to the Moon and Mars.
