内容总结:
美国商业航天企业斯托克航天公司(Stoke Space)近日宣布完成一笔约10亿美元的E轮融资,资金将用于其首枚全可重复使用火箭“新星”(Nova)的首次发射准备,并同步推进更大运力型号的设计升级。
本轮融资由Point72 Ventures和Spark Capital联合领投,General Innovation、Glade Brook Capital、美国创新科技、Washington Harbour Partners、Woven Capital、Y Combinator等机构参投。斯托克航天首席执行官兼联合创始人安迪·拉普萨向GeekWire表示,最终融资金额在“四舍五入误差范围内”接近10亿美元,可能略少或略多,且整个融资进程非常迅速。
拉普萨称,公司成立之初就将放大“新星”火箭设计纳入规划,但鉴于市场发射需求持续增长、可用发射窗口日益紧张,技术迭代时间表因此加快。他表示,这一战略转向并非由单一事件触发,而是近两年市场压力不断累积的结果。
斯托克航天总部位于华盛顿州肯特市,同时在东部173英里处的摩西湖拥有火箭测试基地。为支撑更宏大的目标,公司正同步扩建测试设施。根据修订后的计划,公司首先将发射最初设计的“新星探路者”(Nova Pathfinder)型号。该火箭一级配备7台“天顶”(Zenith)发动机,二级“仙女座”(Andromeda)发动机集成24个推力室并配备主动冷却金属隔热罩,近地轨道运力为3吨。探路者号首飞定于2027年初,届时将搭载加州小行星采矿公司AstroForge的航天器飞往小行星带,开展稀有金属等矿产勘探与开采任务。
放大版“新星Block 2”型号预计2029年首飞,一级发动机数量翻倍至14台“天顶”发动机,二级配备12台独立双推力室发动机,运力提升至探路者号的5倍,近地轨道运力可达15吨,地球同步转移轨道运力超过4吨。作为对照,SpaceX部分可重复使用的猎鹰9号火箭在回收模式下近地轨道运力为18.5吨,同步转移轨道运力为5.5吨。
两种型号的“新星”火箭均设计为完全可重复使用,一级助推器自主飞回回收船,二级独立再入返回。斯托克航天是航天业第二家采用这一双级回收策略的企业——SpaceX的“星舰”系统虽按双级回收设计,目前尚未实现该目标。斯托克正在研发二级可重复使用的主动冷却系统:将低温液态氢推进剂循环通过二级金属隔热罩内部通道,以吸收大气再入时产生的高温。SpaceX一直在试验不同隔热罩方案,但部分专家对其技术路线存有疑虑。
两家企业的产品定位不同:斯托克的两种型号瞄准中型发射市场两端,而SpaceX的超重型“星舰”设计近地轨道运力高达100至150吨。斯托克在肯特市面积16.8万平方英尺的工厂和总部从一开始就按可生产比“新星探路者”更大的火箭来规划。拉普萨表示:“我们直接引入金属板材,制造核心结构,输出一枚火箭。同样的方法和工具可扩展用于更大直径和长度的火箭,这是有意为之。”
摩西湖测试基地正从75英亩扩建至550英亩,以支持两型火箭并行测试。拉普萨称现有75英亩利用效率极高,扩建后各测试台架将拥有完全独立的运行空间,避免爆破半径重叠带来的相互干扰。公司位于佛罗里达州卡纳维拉尔角太空军基地的发射设施同样支持双轨推进,新建的有效载荷处理设施规模兼顾“探路者”和“Block 2”两种型号。
今年6月,摩西湖基地完成“新星探路者”首飞火箭一级的所谓“原型认证测试”,二级推进器即将运往摩西湖进行结构验收测试和静态点火测试,随后送往卡纳维拉尔角。一级火箭也在准备发运,将在发射台上完成与摩西湖相同的湿式演练和静态点火测试,最终两段组装后飞向太空。
自2019年拉普萨与联合创始人兼首席技术官汤姆·费尔德曼离开杰夫·贝索斯旗下的蓝色起源公司创立企业以来,斯托克航天一直保持高速增长。目前公司约有400名员工,其中摩西湖和卡纳维拉尔角各约50人,其余多数在肯特总部,另有少量远程办公人员。
尽管尚未完成任何发射任务,但该公司向这一里程碑稳步推进的进程以及对火箭完全可重复使用的长期愿景,持续吸引着投资方。Point72 Ventures合伙人克里斯·莫拉莱斯表示:“我们通过多轮融资支持斯托克,相信这家公司已展现出卓越的技术进步和以工业级规模服务市场的雄心。”Spark Capital普通合伙人克莱·费舍尔则评价:“完全可重复使用是市场不可避免的终局,与部分可重复使用火箭相比可形成数量级的成本和服务优势。斯托克七年前就提出了正确理论,又以惊人执行速度兑现了这一前瞻判断,因此能在客户需要时提供更多选择和运力,并开启太空领域巨大的新经济空间。”
拉普萨对投资方的信任表示感谢:“我们对这笔投资深感谦卑,有优秀伙伴在背后支持。这是文明发展关键节点上至关重要的一刻。太空开发对我们文明持续扩展和提升生活质量具有极其重要的意义,我们很高兴能参与其中。”

斯托克航天表示,已筹集约10亿美元资金,为完全可重复使用的“新星”火箭首次发射做准备——并扩大火箭设计规模,以承载更重的有效载荷。
为配合其更宏大的蓝图,这家总部位于华盛顿州肯特市的初创公司也在扩建其位于东部175英里处摩西湖的火箭试验设施。
“我们对今天奠定的基础充满信心,现在是扩大规模的时候了。”斯托克航天首席执行官兼联合创始人安迪·拉普萨告诉GeekWire。
此次新宣布的E轮融资由Point72 Ventures和Spark Capital联合领投,General Innovation、Glade Brook Capital、US Innovation Technology、Washington Harbour Partners、Woven Capital、Y Combinator及其他投资者参与投资。
最终金额将在10亿美元的“四舍五入误差范围内”,拉普萨表示。“差不多,或多一点,”他说,“这轮融资推进速度非常快。”
拉普萨表示,扩大“新星”火箭设计规模一直是斯托克航天的计划之一,但时间表正在加快,以响应日益增长的发射需求和发射机会的减少。
拉普萨表示,斯托克转向更大运载火箭的时机并非由单一事件触发。“过去几年压力一直在累积,”他说,“最近当然也没有放缓。”
从“探路者”到Block 2
修订后的计划要求斯托克先以最初设计的火箭(现称“新星探路者”)开始发射任务。“探路者”的第一级将由七台斯托克“天顶”发动机提供动力,第二级的“仙女座”发动机将拥有一个由24个推力室组成的环形阵列,集成在主动冷却的金属隔热罩中。该火箭将能够将3吨有效载荷送入近地轨道(LEO)。
“探路者”的首次发射现定于2027年初——比此前预期略有推迟。它将为总部位于加利福尼亚州的小行星采矿公司AstroForge搭载一艘航天器。“我们要去小行星带,是的,AstroForge是我们那次任务的合作伙伴,”拉普萨说,“他们希望勘探并最终开采小行星,将稀土和其他重要材料带回地球。”
斯托克航天火箭的超大版本,称为“新星Block 2”,预计将在2029年首次亮相。其第一级的“天顶”发动机数量将是“探路者”的两倍。其第二级将有12台独立发动机,每台配备两个推力室。这将使“新星”的运载能力提升五倍,能够将近地轨道有效载荷提升至15吨。超过4吨的有效载荷可送往地球同步转移轨道(GTO)。
相比之下,SpaceX表示其部分可重复使用的“猎鹰9号”火箭在可重复使用模式下可向近地轨道运送18.5吨或向地球同步转移轨道运送5.5吨有效载荷。
两个版本的“新星”火箭都设计为完全可重复使用,第一级助推器自行飞回回收船,第二级单独再入大气层。斯托克是航天工业中第二家采用该战略的公司。SpaceX设计了“星舰”发射系统以实现两级可重复使用,但尚未实现这一目标。
斯托克正在为第二级可重复使用开发主动冷却系统。火箭部分低温冷却的液氢推进剂通过第二级金属隔热罩中的通道循环,以吸收大气再入时产生的剧烈热量。SpaceX一直在尝试“星舰”的不同隔热罩方案,但一些专家对SpaceX的方法表示质疑。
斯托克火箭的两个版本都旨在填补不同于“星舰”的市场空白。“新星”火箭的运载能力接近中等运力范围的两端,而SpaceX的超重型“星舰”设计用于将近地轨道有效载荷提升至100至150吨。
扩建基础设施
斯托克航天位于肯特市、占地16.8万平方英尺的工厂和总部设施从一开始就设计用于制造比“新星探路者”更大的火箭。
“我们运入原材料金属板,建造核心结构,然后运出火箭,”拉普萨说,“我们可以用同样的方法和同样有效的工具来制造更大直径和更长的部件,这是非常有意为之的。”
该公司位于摩西湖的火箭试验设施正在从75英亩扩建至550英亩,以同时容纳两种类型火箭的测试工作。
“我认为我们在利用现有75英亩土地方面做得非常高效,”拉普萨说,“街对面的扩建将使我们的测试节奏再次提速……我们的一些设施存在重叠的爆炸半径,因此它们会相互干扰。能够稍微伸展一下翅膀,获得更多空间的一大优势是,那些试验台可以完全独立运行。”
斯托克位于佛罗里达州卡纳维拉尔角太空军基地的发射设施也可以容纳双轨方法。该基地的新有效载荷处理设施特意按支持“新星探路者”和Block 2两种型号的规模设计。
今年6月,斯托克航天在摩西湖的设施完成了该公司所称的首枚“新星探路者”火箭第一级助推器的原型鉴定测试。“第二级很快将发货,”拉普萨说,“它将运往摩西湖……这将是结构验收测试,然后我们将在那里进行静态点火测试,以充分检验第二级,之后它将运往卡纳维拉尔角。”
助推器也在准备运往卡纳维拉尔角。“我们将重复在摩西湖进行的湿彩排演练,但会在发射台上进行,”拉普萨说,“然后做同样的事情:在那边对第一级进行静态点火测试,然后两级合体,我们飞向太空。”
自2019年拉普萨与联合创始人、首席技术官汤姆·费尔德曼离开杰夫·贝索斯的蓝色起源航天企业创办斯托克公司以来,斯托克航天一直处于惊人的增长曲线上。
拉普萨表示,斯托克目前约有400名员工。“大约50人在摩西湖,50人在卡纳维拉尔角,我们有少数远程员工,其余所有人都在肯特,”他说。
尽管斯托克航天尚未发射火箭,但这家初创公司朝着这一里程碑的稳步进展——以及其完全可重复使用火箭的长期愿景——已足以让投资者继续支持。
“在支持斯托克经历了多个成长阶段后,我们相信这家公司已经展示了卓越的技术进步和雄心,能够构建一套以工业规模服务市场的发射系统。”Point72 Ventures合伙人克里斯·莫拉莱斯今天在新闻稿中表示。
“完全可重复使用是市场的必然终态,与部分可重复使用火箭相比,将提供数量级的成本和服务优势,”Spark Capital普通合伙人克莱·费舍尔表示,“斯托克七年前就提出了正确的论点,并将这种先见之明与惊人的执行速度相结合。因此,他们处于独特的位置,能够在客户需要时提供更多选择和运力,并开启太空中巨大的新经济。”
拉普萨表示,他对这份信任投票心存感激。
“我们对这笔投资感到受宠若惊,身后有强大的合作伙伴支持,”他说,“这对我们作为一个文明来说是一个极其关键和重要的时刻。我认为太空发展对我们文明继续扩展和持续提高我们所享有的生活质量的能力至关重要——我们很荣幸能参与其中。”

Stoke Space says it has raised roughly $1 billion to get ready for the first launch of its fully reusable Nova rocket — and to scale up the rocket’s design for even bigger payloads.
To accommodate its grander ambitions, the Kent, Wash.-based startup is also scaling up its rocket test facility in Moses Lake, 175 miles to the east.
“We have confidence in the foundation that we’ve laid today, and now it’s time to scale,” Stoke Space CEO and co-founder Andy Lapsa told GeekWire.
The newly announced Series E financing round was co-led by Point72 Ventures and Spark Capital, with participation from General Innovation, Glade Brook Capital, US Innovation Technology, Washington Harbour Partners, Woven Capital, Y Combinator and other investors.
The final figure will be “within rounding error” of a billion dollars, Lapsa said. “Not quite, or a little more,” he said. “The speed with which this has come together is very fast.”
Lapsa said that scaling up the Nova rocket’s design was always part of Stoke Space’s game plan, but that the timeline is being accelerated in response to the growing demand for launches and the shrinking availability of launch opportunities.
The timing of Stoke’s pivot to a bigger launch vehicle wasn’t sparked by a single event, Lapsa said. “The pressure has been growing over the last couple of years,” he said. “It certainly hasn’t slowed down recently.”
From Pathfinder to Block 2
The revised plan calls for Stoke to begin launching missions with the initially designed rocket, now known as Nova Pathfinder. Pathfinder’s first stage will be powered by seven of Stoke’s Zenith engines, and the upper stage’s Andromeda engine will have a ring of 24 thrust chambers integrated into an actively cooled metallic heat shield. The rocket will be capable of putting 3 metric tons of payload into low Earth orbit, or LEO.
Pathfinder’s first launch is now scheduled for early 2027 — a slight slip from earlier expectations. It will carry a spacecraft for AstroForge, a California-based asteroid mining company. “We’re going out to the asteroid belt, and yeah, Astroforge is our partner for that one,” Lapsa said. “They’re looking to prospect and ultimately mine asteroids, and bring back rare earths and other important materials.”
The super-sized version of Stoke’s rocket, known as Nova Block 2, is due to make its debut in 2029. Its first stage will have twice as many Zenith engines as Pathfinder. Its upper stage will have 12 independent engines, each with two thrust chambers. That will increase Nova’s lift capability by a factor of five, enabling up to 15 metric tons of payload to be delivered to LEO. More than 4 tons can be sent to geosynchronous transfer orbit, or GTO.
In comparison, SpaceX says its partially reusable Falcon 9 rocket can deliver 18.5 tons to LEO or 5.5 tons to GTO in reusable mode.
Both versions of the Nova rocket are designed to be fully reusable, with the first-stage booster flying itself down to a recovery ship and the upper stage making a separate re-entry. Stoke is only the second company in the space industry to pursue that strategy. SpaceX has designed its Starship launch system for dual-stage reusability but hasn’t yet reached that goal.
Stoke is developing an active-cooling system for upper-stage reusability. Some of the rocket’s cryogenically cooled liquid hydrogen propellant is circulated through channels in the upper stage’s metallic heat shield to absorb the intense heat of atmospheric re-entry. SpaceX has been experimenting with different heat shield strategies for Starship, but some experts have expressed doubts about SpaceX’s approach.
Both versions of Stoke’s rocket are designed to fill a market niche that’s different from Starship’s. The Nova rockets’ capabilities fall close to both ends of the medium-lift spectrum, while SpaceX’s super-heavy-lift Starship is designed to loft 100 to 150 tons of payload to LEO.
Expanding the infrastructure
Stoke Space’s 168,000-square-foot factory and headquarters facility in Kent was designed from the beginning to manufacture rockets that are bigger than Nova Pathfinder.
“We bring in raw sheet metal, we build our core and we ship a rocket,” Lapsa said. “We can use the same methods and effectively the same tooling to build larger diameters and larger lengths, and that’s very intentional.”
The company’s rocket test facility in Moses Lake is being expanded from 75 to 550 acres to accommodate work on two types of rockets simultaneously.
“We’ve done, I would say, an extremely efficient job at leveraging the 75 acres that we use today,” Lapsa said. “The expansion across the street is going to enable us to test again at rate. … Certain of our facilities have an overlapping blast radius, so they interfere with each other. A big advantage of being able to spread our wings a little bit, and get a little bit more space, is that those test stands can operate in full independence of each other.”
Stoke’s launch facilities at Cape Canaveral Space Force Station in Florida can also accommodate a dual-track approach. A new payload processing facility at the Cape is intentionally sized to support both Nova Pathfinder and Block 2.
In June, Stoke Space’s Moses Lake facility completed what the company called proto-qualification testing of the first-stage booster for its first Nova Pathfinder rocket. “The second stage will ship out pretty soon,” Lapsa said. “That goes to Moses Lake. … This will be acceptance testing of the structure, and then we’ll do a static hot-fire test out there to fully shake down the second stage, and then it ships out to Cape Canaveral.”
The booster is being prepared for shipping to the Cape as well. “We’ll repeat the wet dress rehearsals that we did in Moses Lake, but we’ll do it on the launch pad itself,” Lapsa said. “Then we’ll do the same thing: static fire test on the first stage down there, and then the two stages go together, and we go to space.”
Stoke Space has been on a phenomenal growth curve since Lapsa and his fellow co-founder, chief technology officer Tom Feldman, left Jeff Bezos’ Blue Origin space venture in 2019 to create the company.
Lapsa said Stoke currently has about 400 employees. “It’s approximately 50 in Moses Lake, 50 in Cape Canaveral. We have a handful of remotes, and then everybody else is in Kent,” he said.
Even though Stoke Space hasn’t yet launched a rocket, the startup’s steady progress toward that milestone — and its long-term vision for total rocket reusability — have been impressive enough to keep investors on board.
“Having supported Stoke through multiple stages of its growth, we believe this company has demonstrated both the exceptional technical progress and the ambition to build a launch system capable of serving the market at industrial scale,” Chris Morales, partner at Point72 Ventures, said today in a news release.
“Full reusability is the inevitable end state of the market, providing an order-of-magnitude cost and service advantage over partially reusable rockets,” said Clay Fisher, general partner at Spark Capital. “Stoke had the right thesis seven years ago and has paired that prescient vision with a blistering pace of execution. As a result, they stand uniquely positioned to give customers more choice and capacity when they need it, and to unlock an enormous new economy in space.”
Lapsa said he’s grateful for the vote of confidence.
“We’re humbled by the investment, having great partners behind us,” he said. “It’s an incredibly critical and important moment for us as a civilization to get right. I think space development is really, really important for our ability as a civilization to continue to scale and continue raising the quality of life that we enjoy — and we’re thrilled to be part of it.”
