Sierra Space

国防业务扩张掩盖了商业航天仍不透明的投资逻辑。

Sierra Space 仍是一家资本充足但信息不透明的航天与国防平台:国防订单和 2026 年 3 月 $8.0 billion 的估值确有依据,但 Dream Chaser 的进度风险、私营公司的财务不透明,以及尚未回答的商业化问题,让投资判断仍停留在继续研究。

1.3 资本结构、私有估值与资产负债表透明度

自 2021 年分拆以来,Sierra Space 已获得超过 $2.0 billion 的股权资本,成为航空航天行业私营估值最高的公司之一。公司于 2021 年 11 月以 $4.5 billion 估值完成 $1.4 billion 的 Series A 融资,2023 年 9 月以 $5.3 billion 估值完成 $290 million 的 Series B,并于 2026 年 3 月 5 日完成 $550 million 的 Series C 股权融资。该轮由 LuminArx Capital Management 领投,General Atlantic、Coatue、Moore Strategic Ventures 和 Andalusian Private Capital 参与,投后估值达到 $8.0 billion。然而,Sierra Space 是一家私营公司,依据 SEC Rule 506(b) 通过 Form D 提交豁免发行,因此明确拒绝披露收入区间。经营利润率、经常性收入、EBITDA、现金消耗率和合并现金余额仍未披露,分析只能依赖合同上限,而非经审计的损益表表现。[CO007, CO008, CO009]

1.4 运营里程碑、运输延误与国防扩张

Sierra Space 的运营路线采取双轨战略:一边探索商业航天,一边激进扩张国家安全卫星生产。旗舰 Dream Chaser 相比 2021 年最初目标大幅延期,首次入轨发射推迟至 2026 年末。2025 年 9 月,NASA 与 Sierra Space 共同修改 Commercial Resupply Services 2(CRS-2)合同,取消首飞必须保证对接 ISS 的要求,将 Demo-1 改为无人自由飞行轨道测试。与此同时,Sierra Space 将大量资源转向国防科技项目。公司获得 Space Development Agency 18 颗卫星 Tranche 2 Tracking Layer 订单,最高潜在价值 $740 million;2026 年 7 月又获得最高 $798 million 的 Other Transaction Authority 订单,为 18 颗 Accelerated Missile Defense Tranche 3 卫星供货。商业目的地开发则继续通过与 Blue Origin 合作的 Orbital Reef 推进,核心是 LIFE 充气式栖息舱。[CO010, CO011, CO012, CO013, CO014]

1.5 战略风险、资本治理与核心尽调缺口

独立评估 Sierra Space 需要审视三类主要风险:私有披露不透明、项目执行瓶颈和资本结构治理。由于公司不发布经审计的损益表,无法仅凭公开文件独立判断国防积压订单的转化质量和节奏。Space Development Agency 的合同授予代表最高潜在合同价值,而非已确认收入。民用太空运输上,Dream Chaser 依赖 United Launch Alliance 的 Vulcan Centaur 火箭完成运载器集成,发射频次瓶颈可能进一步推迟商业验证。此外,Series C 优先股的清算优先权、反稀释保护和赎回约定等具体条款仍属机密,二级股份估值及普通股上行空间必须通过闭门审阅投资者权利协议直接核实。[CO009, CO010, CO011]

02市场分析

2.1 市场边界与向国防科技的战略转向

Sierra Space 横跨两条不同市场边界:高增长的国家安全航天系统,以及长周期商业低地球轨道(LEO)基础设施。国家安全业务包含大规模小卫星星座、战术在轨交会飞行器和快速大气层载荷返回,但不包含重型运载火箭和传统单体式地球静止轨道军用通信平台。在地缘政治紧迫性和国防部重振本土航天工业基础的优先事项推动下,Sierra Space 转向成为核心国防科技主承包商。主要国防订单——包括 Space Development Agency 为 18 颗跟踪层卫星授予的 $740 million 合同,以及 $450 million 的机密卫星订单——验证了客户需求,也让近期收入明确转向国防采购。[CM001, CM006, CM007, CM008, CM013]

[CM001, CM002, CM006, CM007, CM009]

2.2 轨道基础设施 TAM、SAM 与 SOM 分析

评估 Sierra Space 的可触达机会,必须将理想化的商业轨道预测与实质国防订单分开。公司内部市场分析确定四个地面目标垂直领域——半导体与先进玻璃、单克隆抗体与药物制剂、细胞检测和再生医学——2022 年合计规模为 $900 billion,按 8.3% CAGR 增长至 2038 年的 $3.6 trillion。以此为地面基准,公司估计截至 2038 年 LEO 累计 TAM 约为 $154 billion,仅相当于地面工业支出的不到 1% 捕获率。Sierra Space 还测算,先发商业空间站可在 30% EBIT 利润率下获得 $64 billion 累计收入。不过这些数字仍属推测;当前 SAM 由已授予的 $1.5 billion 国防合同界定。[CM002, CM003, CM004, CM005, CM008, CM014]

2.3 买方细分与政府采购动态

Sierra Space 的主要客户由拥有专门法定预算的政府机构买方主导。在国家安全领域,Space Development Agency 和国防情报机构是主要买方及预算所有者,按多年拨款周期采购大规模导弹跟踪卫星平台和专业情报卫星。在民用航天领域,NASA 通过 Commercial Resupply Services 2(CRS-2)合同兼任锚定买方和付款方,采购运往 International Space Station 的加压货运服务。商业客户虽是微重力生物制造和栖息舱平台的长期目标用户,但私营企业的采用仍处早期,除政府支持的研究计划外,尚无具有约束力的商业采购承诺。[CM001, CM006, CM007, CM009, CM012]

2.4 采用约束、竞争壁垒与尽调缺口

Sierra Space 的航天飞机和轨道栖息舱平台面临严重的运营与竞争约束。Dream Chaser 商业化一再延期,首次飞行从运营型 ISS 补给对接任务改为 2026 年末无人自由飞行演示。该飞行器仍高度依赖 United Launch Alliance 的 Vulcan 火箭,而后者累计飞行经验有限。与此同时,SpaceX 的 Dragon 凭借已验证的飞行可靠性、高发射频次和结构性成本优势建立了牢固壁垒。关键尽调缺口在于:International Space Station 补贴结束后,商业制药和工业企业是否愿意为微重力制造支付可盈利的商业价格。[CM010, CM011, CM012, CM014]

3.1 竞争集合随任务而变

Sierra Space 很难与某一个同质化同行群体直接比较。公司定位横跨国家安全、民用和商业任务,而独立目录分别将发射服务商、卫星制造商、商业空间站开发商和传统国防主承包商列为替代者。Distill 列出 SpaceX、Axiom Space、Blue Origin、Firefly Aerospace、Apex、Lockheed Martin、Northrop Grumman、Boeing、Voyager 和 Rocket Lab;Craft 则聚焦 Firefly、bluShift、Xplore 和 SpinLaunch;Owler 将 Relativity Space 列为最大竞争者。分歧具有分析意义:竞争应按采购任务评估,而不是把所有航天公司都视为直接替代者。自研和现状仍是相关尽调类别,但分配的证据池未识别或量化它们。[CP001, CP012, CP013, CP014, CP015]

3.2 广度形成差异化,但多数主张仍来自公司自身

Sierra Space 披露的范围不止一艘航天器。公司称其子系统和组件覆盖 23 艘航天器以及超过 400 次成功的航天和星际任务,并介绍了用于在轨服务的新一代小卫星产品线。其国家安全页面还展示了用于载荷返回的 Ghost、用于交会和近距离操作的 Spectre,以及基于零信任架构、支持 AI 且与平台无关的 Sierra 操作系统。这样的广度有利于交叉销售和复用生产基础设施,但不等于已独立证明与每个专业厂商相当。2026 年 10 月访问时,同一官方页面仍称 Spectre 计划于 2025 年末发射,却未说明结果,因此路线图主张应与已交付能力分开评估。[CP002, CP003, CP004, CP005, CP006]

3.3 资本与政府订单强化准入,但定价权不明

Sierra Space 在资本与政府采购上拥有清晰位置。公司 2026 年 3 月发布的公告披露,以 $8 billion 投后估值获得 $550 million 股权投资,资金将用于扩充产能和国家安全解决方案。同一公告还披露了 $450 million 的四颗以上卫星建造订单,以及价值最高 $740 million、面向 18 颗卫星的 SDA Tranche 2 Tracking Layer 合同。这些订单说明公司能够进入有资金支持的项目并获得生产需求,但合同最高价值不是已确认收入,也不能揭示单位经济性。现有证据还未披露目录价、实际价格、折扣、续约机制、客户集中度、终止权,或客户能否在供应商之间多家采购。[CP007, CP008, CP009, CP010, CP011]

[CP007, CP008, CP009, CP010]

3.4 壁垒取决于交付,而非类别标签

现有证据池中最有防守力的要素是积累的飞行经验、当前产能、大型项目订单,以及跨卫星、子系统、返回飞行器和自主软件销售的能力。一篇独立行业文章称 Sierra Space 提前三个月完成 SDA 项目前九个结构件,但该报道依赖公司披露,并非政府验收记录。下行风险在于执行和可比性:产品组合中有些项目的当前里程碑状态未披露,第三方同行目录也未就直接竞争集合达成一致。人才同样存在争议;Built In 描述了市场化薪酬、激励和股权工具,但这些做法不能证明留任或生产率。因此,持久优势需要经验证的按时交付、重复订单和经济性披露,而不只是业务广度。[CP002, CP005, CP011, CP015, CP016]

Sierra Space 的收入来自民用太空运输、国家安全载荷和国防子系统,但收入基础的构成及未来稳定性正经历结构性转变。其商业基础过去由 NASA 于 2016 年授予、至少包含七次货运任务的 Commercial Resupply Services-2(CRS-2)合同支撑;2025 年 9 月 NASA 与 Sierra Space 共同修改合同后,情况发生变化。根据修订,NASA 将 Tenacity 首飞改为计划在 2026 年末进行的无人自由飞行演示,并取消购买固定数量运营补给飞行的承诺。为弥补保证性民用货运收入减少,Sierra Space 于 2026 年 9 月宣布已为 Dream Chaser 首飞预订未披露的国家安全和商业载荷,形成混合多载荷运营模式。更广泛的国防组合中,Orbital Missions and Services 部门依托超过 400 次历史任务贡献组件和卫星平台收入,但细分里程碑确认时间表和利润率贡献仍未披露。[CI001, CI002, CI003, CI004, CI005, CI006, CI009, CI014]

4.2 成本结构、运载火箭依赖与单位经济性

Dream Chaser 的经济可行性取决于可重复使用航天飞机的单位经济性、飞行器周转成本和第三方运载器采购费用。与 SpaceX Dragon 和 Northrop Grumman Cygnus 等在再入时溅落或烧毁的太空舱不同,Dream Chaser 的设计是在低于 1.5g 的低加速度下,将最多 1,750 kilograms 的精密货物送回符合 Boeing 737 评级的标准跑道。该设计无需海上回收物流即可取回客户硬件,也让载荷可以避免完整环境鉴定测试。然而,飞行层面的单位成本很大程度受外部发射采购拖累:Sierra Space 依赖 United Launch Alliance 的 Vulcan Centaur 火箭将 Tenacity 送入轨道,任务利润率因此暴露于运载器价格、可用性和排期异常。飞行器周转人力、热防护瓦翻修,以及 Vandenberg Space Force Base 的自主跑道着陆运营也尚未在实际飞行中验证,因此在取得首次飞行演示数据前,生命周期毛利率预测仍属推测。[CI007, CI008, CI010, CI011, CI012, CI013]

4.3 资本充足性、现金消耗风险与机构投资判断

Sierra Space 通过 LuminArx Capital Management 领投的 2026 年 3 月 $550 million Series C 融资建立了充足流动性,累计私有资本募资额超过 $2.2 billion,投后估值达到 $8.0 billion。但公司处于资本密集型开发环境,航天飞机制造、飞行鉴定和国防卫星产品线持续消耗大量现金。由于 Sierra Space 不公开披露 GAAP 收入、毛利率、EBITDA 或经营净现金流,机构投资判断无法核实其披露的 $3.4 billion 积压订单究竟是有资金支持的固定总价任务订单,还是不具约束力的框架协议。NASA 的 CRS-2 承诺如今取决于成功演示,而 International Space Station 计划于 2030 年退役;在确认经常性国防合同和商业下行货运客户承诺前,未来收入可见性不足以支撑机构投资判断。[CI003, CI004, CI007, CI008, CI009, CI013, CI014]

05产品与技术

5.1 可重复使用航天飞机运输与 Dream Chaser 平台

Sierra Space 的运输业务以 Dream Chaser 为核心。这是一种可重复使用的升力体航天飞机,设计为装在标准五米火箭整流罩内垂直发射,再水平返回常规商业跑道。Dream Chaser 在 2021 年公司分拆前由 Sierra Nevada Corporation 开发,设计目标是在低于 1.5 g 的低重力大气再入减速度下运行,为敏感科学实验、生物制造载荷和返回宇航员提供关键保护。基础无人货运配置可搭载最多 5,000 kg 加压载荷和 500 kg 非加压货物,并配备一次性 Shooting Star 后舱,提供电力、主动热控和额外货物处理。首架飞行器 Tenacity 计划从 Kennedy Space Center 发射并在 Vandenberg Space Force Base 着陆,执行轨道演示飞行,目标是无人自由飞行而非首次空间站对接。相比传统太空舱溅落,该架构运营灵活性更高,但 Sierra Space 仍需解决 ULA Vulcan Centaur 火箭集成、热防护瓦耐久性,以及在扩展到载人配置前证明多任务周转效率等执行难题。[CE001, CE002, CE003]

5.2 充气式栖息系统与商业空间站目的地

Sierra Space 的轨道基础设施战略以 Large Integrated Flexible Environment(LIFE)栖息舱模块为支点。LIFE 采用可扩展软性压力壳,由高强度编织约束带、内部气囊保压屏障和外部微流星体及轨道碎片(MMOD)防护毯构成。模块以紧凑形态装入五米载荷整流罩,入轨后展开为约 285 cubic meters 的三层楼高加压空间;一次专门发射即可提供约三分之一的 International Space Station 总加压容积。Sierra Space 在 NASA Marshall Space Flight Center 完成全尺寸极限爆破压力测试,证明设计结构完整性及超过安全要求的压力裕度。LIFE 是 Sierra Space 对 Orbital Reef 的主要栖息贡献;Orbital Reef 是与 Blue Origin 共同牵头、Boeing 和 Redwire 等伙伴支持的商业低地球轨道空间站。但该计划面临开发摩擦和企业优先级分歧。联盟获得 $130 million 的 NASA Commercial LEO Destinations(CLD)Phase 1 基础订单后,截至 2026 年仅拨付 $24 million;Blue Origin 也越来越优先推进数十亿美元的 Blue Moon 月球着陆器项目。NASA 虽已完成 System Definition Review,并将最终 CLDC Phase 2 RFP 排在 2026 年 9 月末,Sierra Space 的 2026 年末 LIFE 探路者飞行仍缺少确认的部署时间,迫使公司建立独立模块飞行履历。[CE004, CE005, CE006, CE007, CE008, CE009]

5.3 标准化卫星平台、在轨加注与国家安全系统

为在长周期空间站项目成熟前创造可扩展工业收入,Sierra Space 开发了 Eclipse 卫星平台系列,覆盖 Horizon、Velocity 和 Titan 三类模块化平台。Horizon 是大规模低地球轨道星座的标准化生产底盘,尤其支持 Space Development Agency 的导弹预警与跟踪架构。Sierra Space 已完成 18 颗 Tranche 2 Tracking Layer 卫星的结构组装,并获得 18 艘 AMDT3 Golden Dome 航天器订单,在科罗拉多州建立高节拍卫星制造线。平台系列集成具备在轨加注能力的专有推进系统,使卫星能够机动、执行交会近距操作,并为国家安全和商业客户延长运行寿命。敏捷工程文化引入早期清单验证,防止子系统在后期偏离,从而加快开发。依托 Orbital Missions and Services 部门的飞行履历——已交付 23 艘完整航天器、支持超过 400 次任务——Sierra Space 将 Eclipse 定位为可靠的多任务底盘,同时应对供应商依赖和高密度传感器载荷的高功率散热问题。[CE010, CE011, CE012, CE015]

5.4 快速地面回收与自主软件架构

作为重型轨道运输的补充,Sierra Space 开发了 Ghost,这是一种一次性低升阻比再入飞行器,利用可展开减速器按需精准返回货物。Ghost 无需固定回收基础设施,可在 90 分钟内将轨道存储或亚轨道轨迹上的载荷安全直接送回指定地面地点,用于战术军事物流和应急补给任务。2026 年 5 月美国太空司令部 Apollo Nexus 演习期间,Ghost 在 Dugway Proving Ground 上空从 35,000 feet 和 68,500 feet 高度投放,成功回收软件定义无线电和液体载荷。Air Force Research Laboratory 的 REGAL 研究正在评估将基础 150 kg 载荷能力扩展至数 tonnes。Sierra Black OS 和 STAR(Sierra Toolkit for Autonomous Rendezvous)软件套件负责控制这些多样化运营领域。Sierra Black OS 基于零信任架构,提供与平台无关的故障安全自主能力、实时传感器融合和多域指挥控制,支持空间、空中和地面系统的交会及近距离操作,将 Sierra Space 的硬件组合统一为国防与商业运营栈。[CE013, CE014, CE015]

7.1 监管与法律风险:分包商诉讼及多机构监督

Sierra Space 处于复杂的法律和监管环境中,国防合同争议及不断变化的太空交通规则直接增加运营和财务摩擦。最严重的法律风险来自丹佛 U.S. District Court 的联邦诉讼:光学和红外传感器供应商 Geost 于 2025 年 1 月向 Sierra Space 提起 $17.1 million 违约诉讼。Geost 指称,Sierra Space 使用其传感器载荷和早期长交期材料投资,获得 Space Force 的 Space Development Agency(SDA)$740 million 合同,为 18 颗 Tranche 2 Tracking Layer 卫星供货,随后于 2024 年 6 月发出停工令并试图用 Leidos 替代 Geost。除供应商争议外,Sierra Space 在民用和商业飞行运营中也面临监管摩擦。公司在 FAA Docket FAA-2023-1858 下提交的正式监管意见中警告,拟议 FAA Part 453 轨道碎片缓解规则与 FCC、NASA 标准存在管辖重叠,发射后避碰要求可能大幅推高 Maximum Probable Loss(MPL)保险需求。[CR001, CR002, CR003, CR004, CR005, CR006]

7.3 合作伙伴与客户依赖风险:NASA 任务压缩与发射瓶颈

Sierra Space 的收入和商业路线图存在高度集中及交易对手风险。根据 NASA Commercial Resupply Services 2(CRS-2)合同,2025 年 9 月修订将 Dream Chaser 首飞(SSC Demo-1)与 ISS 对接要求脱钩;在 NASA 准备于 2030 年退役 ISS 之际,取消了七次运营空间站补给对接的保证。此外,Dream Chaser 依赖 United Launch Alliance(ULA)的 Vulcan Centaur 运载火箭,任务时间表因此暴露于助推器发射节奏瓶颈。Sierra Space 虽通过大幅转向国家安全国防科技积极降低民用航天风险——获得超过 $1.5 billion 的国防卫星积压订单,包括 2026 年 7 月新增的 $798 million SDA 合同——但业务仍依赖联邦预算授权,以及与 Blue Origin 在 Orbital Reef 空间站上的合作一致性。[CR012, CR013, CR014, CR015, CR016]

Chapter 08

08估值

8.1 投资逻辑与反向逻辑

Sierra Space 已在国家安全国防和轨道基础设施领域建立战略位置 [CV004]。核心投资逻辑是双引擎增长战略:扩大高优先级国家安全国防平台,同时将太空运输和栖息舱基础设施商业化 [CV005]。2026 年 3 月,公司完成由 LuminArx Capital Management 领投的 $550 million Series C 融资,累计投资额超过 $2 billion,投后估值重估至 $8.0 billion [CV001, CV002]。运营层面的关键优势是可重复的国防业务,包括 $740 million 导弹跟踪订单,以及 2026 年追加的 $798 million、面向 18 颗卫星的订单 [CV003]。反向逻辑则来自严重的财务不透明和技术执行瓶颈 [CV007]。Sierra Space 是私营公司,不公开披露详细财务报表、收入运行率或毛利率 [CV007]。此外,其旗舰商业航天飞机 Dream Chaser 遭遇延期,导致首次发射受阻,原定的 International Space Station 对接也被取消;公司直到 2025 年 11 月才在 NASA Kennedy Space Center 完成飞行前测试 [CV008]。如果商业航天基础设施采用速度落后于国防制造产能,这些因素将造成不对称的下行风险。

8.2 融资背景、资本结构与估值纪律

Sierra Space 的资本轨迹显示,估值快速增长的同时,资本密集度也很高 [CV001, CV002]。公司于 2021 年从 Sierra Nevada Corporation 分拆出来后完成 $1.41 billion 的 A 轮融资;2023 年 9 月估值达到 $5.3 billion,2026 年 3 月投后估值达到 $8.0 billion [CV001, CV010]。在二级及 IPO 前经纪市场中,二级模型估值达到 $9.14 billion,反映出散户和合格投资者通过 UpMarket 等平台的投机性需求,但这些交易受到严格的低流动性和转让限制约束 [CV009, CV011]。公司域名下运营的商业商品和品牌渠道,也进一步说明 公司正在核心航空航天防务业务之外推进品牌认知 [CV016]。不过,公开证据显示,Series C 优先权、优先清算倍数,以及 LuminArx、Coatue 和 General Atlantic 等机构投资方可能持有的下轮融资棘轮保护,仍存在重大结构性信息缺口 [CV006, CV010]。 在缺少经审计收入或国防积压订单转化计划验证的情况下,以高于 $8.0 billion 私募市场 headline 倍数的价格买入,会让投资者暴露于显著的 倍数压缩和稀释风险 [CV007, CV012]。

8.3 情景分析、可比背景与尽调框架

估值判断需要评估公司在国防合同和商业太空基础设施上的非对称经营路径 [CV003, CV005]。在乐观情景下,Sierra Space 会快速扩大 Victory Works 工厂规模,将 $798 million 的卫星积压订单转化为两位数 EBITDA 利润率,并成功执行 Dream Chaser 和 Ghost 运载系统的 商业飞行 [CV003, CV005]。基准情景下,国防生产保持稳定,但 Dream Chaser 商业收入受认证周期拖累,爬坡缓慢,企业价值维持在 $8.0 billion 附近 [CV001, CV008]。悲观情景下,航天飞机项目持续延期或卫星合同利润率下滑,叠加高额经营现金消耗,触发下轮融资或结构化优先权 的悬置风险 [CV007, CV008]。将 Sierra Space 与 Terran Orbital(融资 $144M,已被收购)、Apex(融资 $718M)和 Vast(2026 年 3 月完成 $500M A 轮)等已获融资的空间系统和硬件竞争者比较,可以看出 Sierra Space 的私募估值处于行业领先梯队 [CV006, CV013]。 因此,在经审计收入披露和轨道飞行验证完成前,更稳妥的建议是继续研究;当前风险高,估值已显得偏紧 [CV014, CV015]。[CV001, CV003, CV005, CV006, CV007, CV008, CV013, CV014, CV015]

SI001 National Aeronautics and Space Administration NASA, Sierra Space Modify Commercial Resupply Services Contract In 2016, NASA awarded a Commercial Resupply Services-2 contract to Sierra Space, formerly part of Sierra Nevada Corporation, to resupply the International Space Station with its Dream Chaser spaceplane and companion Shooting Star cargo module. As part of its contract, Sierra Space was awarded a minimum seven flights, and the agency previously issued firm-fixed price task orders for four Dream Chaser resupply missions based on the needs of the space station. ... As part of the modification, NASA is no longer obligated for a specific number of resupply missions; however, the agency may order Dream Chaser resupply flights to the space station from Sierra Space following a successful free flight as part of its current contract.
SI002 Aerospace America After NASA contract change, Sierra Space seeks path forward for Dream Chaser The agency said it’s “no longer obligated” to use Dream Chaser for a specific number of resupply missions. It could still contract Sierra for future deliveries, but that would largely depend on the results of Tenacity’s inaugural flight, now slated for late 2026. Instead of visiting ISS, the spaceplane is to conduct a “free-flyer demonstration mission” to low-Earth orbit. Separately, Sierra described that shift as part of a larger “strategic transition” to market Dream Chaser “for future national security and defense demonstrations.” But the change also left some industry observers wondering whether the spacecraft will ever actually go into service.
SI003 Sierra Space Sierra Space Secures National Security and Commercial Payload Contracts for Dream Chaser Inaugural Flight Sierra Space, a defense-tech space company delivering solutions for the nation’s most critical missions and advancing the future of security in space, announced today that it has secured contracts with undisclosed national security and commercial customers to fly payloads aboard Dream Chaser®—the only commercial reusable, runway-capable spaceplane—on its inaugural mission.
SI004 The Defense News Sierra Space to Carry Mixed NASA, National Security and Commercial Payloads on Dream Chaser’s First Flight Sierra Space has signed contracts with undisclosed national security and commercial customers to fly payloads on the first orbital mission of its Dream Chaser spaceplane. The company announced the agreements on September 2, adding new payloads to a debut mission that has faced years of delays. The reusable, uncrewed spacecraft, named Tenacity, is scheduled to launch from Kennedy Space Center in Florida aboard a United Launch Alliance (ULA) Vulcan Centaur rocket.
SI005 Cosmic Herald Sierra Space Books National Security Customers for Dream Chaser's First Flight The company has booked national security, civil and commercial customers to share the vehicle's first mission alongside its original job: hauling cargo to the International Space Station under NASA's Commercial Resupply Services program. It's an unusual way to debut a spacecraft. Most vehicles prove themselves on a single, low-stakes shakeout flight before anyone trusts them with sensitive payloads. Dream Chaser, according to Sierra Space, is skipping that staging step and going straight to a mixed manifest that includes defense-related cargo.
