内容总结：

美国华盛顿州博塞尔市的Portal航天系统公司近日宣布推出新型快速机动航天器"星爆"，这是该公司继"超新星"平台后产品线的又一重要拓展。

根据计划，"星爆-1"将于一年后搭乘SpaceX的Transporter-18共享发射任务进入太阳同步轨道，执行首次在轨实载验证飞行。该任务将重点演示航天器交会对接、快速任务重置和快速轨道变更等关键技术，这些能力在商业星座与国家安全领域具有重要应用价值。

值得关注的是，"星爆"平台采用了与大型平台"超新星"相同的氨推进剂技术和核心制造工艺，这种技术共享策略既加速了现有机动平台的部署，也为后续更强大平台的研发奠定了验证基础。公司首席执行官杰夫·索恩伯格表示，这一发展路径既能满足客户当前需求，又能为未来轨道转移能力做好技术储备。

据悉，此次任务将搭载由加州TRL11公司提供的立体视频监测系统，以及新西兰Zenno宇航公司研发的超导磁力执行器，后者将验证卫星精确定位与协同操控技术。该公司透露，"星爆-1"任务完全由企业自筹资金开展，旨在通过实际在轨验证为2027年启动的商业客户任务奠定技术基础。

目前，采用分布式星座架构的航天系统正成为行业发展趋势，SpaceX星链和亚马逊柯伊伯计划等商业星座已广泛应用该理念，在国家安全领域的应用也日益增多。"星爆"平台的推出，标志着小型卫星星座正式迈入高机动能力的新阶段。

总部位于华盛顿州博塞尔的Portal航天系统公司近日为其产品线新增一款航天器：名为"星爆"的快速机动飞行器，该产品借鉴了正在为其更强大的"超新星"卫星平台研发的多项技术。

按计划，"星爆-1"将于一年后通过SpaceX的Transporter-18拼单任务发射升空，成为Portal首款搭载实景载荷的自由飞行太空任务核心。该公司表示，此次任务将演示交会对接与近距离操作、快速重定向及快速轨道变更能力，以满足国家安全与商业应用需求。

"星爆"专为依赖小型卫星星座的任务设计，这种分布式空间架构模式已应用于SpaceX星链、亚马逊柯伊伯计划等商业星座，在国家安全领域也日益受到青睐。

Portal指出"星爆"平台与大型"超新星"平台将共享众多制造工艺与核心系统，包括正在为"超新星"研发的推进系统。与"超新星"相同，"星爆"将采用加热氨作为推进剂。

"我们的战略是既满足客户当前需求，又加速实现其未来所需。"Portal首席执行官杰夫·索恩伯格在新闻稿中表示，"'星爆'为运营商提供适应分布式架构的机动平台，'超新星'则实现跨轨道抵达能力。2026年发射'星爆-1'能快速形成实战能力，并通过共享系统验证为2027年问世的'超新星'奠定信心。"

"星爆-1"入轨后将在太阳同步轨道执行为期一年的主任务。该公司设定的轨道机动目标为每秒1公里总速度增量，相当于时速超过2200英里的速度变化。

这款ESPA级航天器将搭载两套载荷：加州TRL11公司提供的立体视频监测系统，以及新西兰Zenno宇航公司研发的超导磁力驱动器。Zenno计划借此演示其卫星定位技术与卫星间精密交互磁控技术。

索恩伯格在邮件中向GeekWire透露："'星爆-1'任务由Portal全额投资，旨在降低风险并向客户验证能力，为未来签约任务铺路。"该公司计划自2027年起面向客户提供"星爆"平台服务。

Bothell, Wash.-based Portal Space Systems has added another spacecraft to its product line: a rapid-maneuverability vehicle called Starburst, which takes advantage of technologies that are being developed for its more powerful Supernova satellite platform.
Starburst-1 is due to star in Portal’s first free-flying space mission with live payloads a year from now, starting with a launch on SpaceX’s Transporter-18 satellite rideshare mission. Portal says the mission will demonstrate rendezvous and proximity operations, rapid retasking and rapid orbital change for national security and commercial applications.
Starburst is designed to bring maneuverability to missions that rely on constellations of small satellites, an approach known as proliferated space architecture. Such an approach is already being used for commercial constellations including SpaceX’s Starlink and Amazon’s Project Kuiper, and the concept is also gaining traction for national security applications.
Portal says the Starburst platform and the larger Supernova platform will share many manufacturing processes and core systems, including the thruster system being developed for Supernova. Like Supernova, Starburst will use heated ammonia as a propellant.
“Our strategy is to deliver what customers need now and accelerate what they’ll need next,” Portal CEO Jeff Thornburg said today in a news release. “Starburst gives operators a maneuverable bus that supports proliferated architectures in the orbit that matters to them. Supernova brings the trans-orbital reach. Flying Starburst-1 in 2026 lets us field capability quickly and advance the shared systems that raise confidence for Supernova’s 2027 debut.”
Starburst-1 is to be deployed into a sun-synchronous orbit for a one-year primary mission. Portal’s target for on-orbit maneuverability is 1 kilometer per second of total delta-v, which translates to a change in velocity amounting to more than 2,200 mph.
The ESPA-class spacecraft will carry two hosted payloads: a stereo video monitoring system provided by California-based TRL11; and a superconducting magnetic actuator provided by New Zealand-based Zenno Astronautics. Zenno plans to demonstrate the magnet technology that it has developed for satellite positioning and precision interactions between satellites.
In an email, Thornburg told GeekWire that “the Starburst-1 mission is completely funded by Portal to reduce risk and prove capability for our customers ahead of future contracted missions.” Portal plans to offer Starburst for customer missions starting in 2027.
