佛罗里达州坦帕消息——Aethero正准备在今年秋季部署其性能最强的计算载荷，旨在将数据中心级别的处理能力带入轨道。该公司于4月16日宣布，将把其下一代NxA-ECM计算模块集成到保加利亚EnduroSat的小卫星平台上。这项名为“Titan”的任务旨在演示超过16,000 TFLOPS的计算性能，这足以实现轨道上的实时数据处理和自主决策，从而减少对有限下行链路容量的依赖。该模块采用了英伟达的Jetson Thor处理器。Titan标志着从Phobos任务（算力约157 TFLOPS）的重大跨越。Phobos是今年初部署的4U立方体卫星，目前正处于健康检查阶段。此前的演示载荷已支持包括博思艾伦咨询公司和美国空军研究实验室（AFRL）在内的多个软件租户。Titan任务预定搭载SpaceX的“运输者17号”发射。

摘要
总部位于旧金山的太空技术初创公司Aethero近日宣布，已向保加利亚EnduroSat公司订购了一颗高性能卫星，用于部署名为“Titan”的轨道数据中心。该卫星将集成基于英伟达Jetson Thor处理器的计算模块，演示超过16,000 TFLOPS的尖端算力。此项技术的应用旨在解决卫星数据传输过程中的延迟问题，实现在轨道上直接对军事情报和遥感数据进行AI处理与自主决策，从而大幅减少对有限地面下行链路的依赖。此前，Aethero已通过实验性任务获得了美国空军研究实验室（AFRL）的支持，验证了在极端太空环境下的计算稳定性。专家指出，轨道边缘计算正成为新一代军用卫星的核心特征，通过将算力前置到太空，可以实现对战场态势的实时感知与快速响应。该项目计划搭载SpaceX的“运输者17号”火箭发射，标志着太空基础设施正从单纯的数据传输向高性能自主处理平台转型。

TAMPA, Fla. — Aethero is preparing to deploy its most powerful computing payload yet this fall, aiming to bring data center-style processing to orbit and expand the scale of AI workloads that can be handled in space.
The San Francisco-based startup announced plans April 16 to integrate its next-generation NxA-ECM compute module with a small satellite bus from Bulgaria’s EnduroSat, using its upcoming ESPA-class FRAME-15 platform with 3.4 kilowatts of peak power.
The Titan mission aims to demonstrate more than 16,000 TFLOPS — a measure of computing performance — which Aethero says is sufficient for real-time data processing and autonomous decisions in orbit, reducing reliance on limited downlink capacity to send raw data back to Earth.
The NxA-ECM module is built around Nvidia’s Blackwell-based Jetson Thor processor, designed to bring significantly more AI computing power to orbit than earlier generations.
Scaling compute in orbit
Titan marks a major step up from the roughly 157 TFLOPS the venture is targeting with Phobos, a far smaller 4U CubeSat deployed earlier this year with tens of watts of power that was largely built in-house to demonstrate early in-orbit computing capabilities.
Amit Pinnamaneni, Aethero cofounder and chief technology officer, said Phobos is still undergoing health checks following its March 30 launch on SpaceX’s Transporter-16 rideshare mission.
Phobos would represent about a 60% increase in performance compared to the Deimos demonstrator Aethero deployed in 2024, its first spacecraft to test a computing payload built around commercial Nvidia hardware. The spacecraft operates as a single compute node supporting multiple software tenants in containerized environments, Pinnamaneni said, including Booz Allen Hamilton and the U.S. Air Force Research Laboratory.
Slated to launch on SpaceX’s Transporter-18 rideshare in October, Pinnamaneni said Titan would scale from a single compute node to a clustered system, “essentially acting as a space cloud provider like a space-based AWS.”
Unlike earlier missions that function more like individual servers, he said Titan is designed to link multiple NxA-ECM compute modules into a coordinated system that shares workloads and operates as a single platform, managed by widely used Kubernetes cloud software.
Each NxA-ECM compute module is designed to deliver more than 4,000 TFLOPS by combining two Nvidia Jetson Thor processors within a single unit, which Pinnamaneni said would make it the first space computer to achieve this level of performance per module.
He said EnduroSat’s production capacity of up to two ESPA-class satellites per day could later enable Aethero to expand beyond a single mission into a distributed network of computing spacecraft.
