Axiom Space has revealed that the company will launch the first of two Orbital Data Center (ODC) nodes to LEO, by year’s end. These nodes will lay the foundation for space-based cloud computing, addressing growing needs for users around the world.

ODCs will provide secure, scalable, and cloud-enabled data storage and processing, and artificial intelligence/machine learning (AI/ML) solutions directly to satellites, constellations, and other spacecraft in Earth’s orbit, with the capability to operate independently of terrestrial infrastructure. This innovative approach reduces reliance on Earth-based systems and also enhances resiliency and security of emerging mesh networks in orbit but also enhances real-time operations of space assets by providing lower latency and higher availability cloud capabilities. Axiom Space’s ODCs will transform space operations, especially in the context of defense and security.

Use cases for ODCs include:

On-orbit and real-time processing, exploitation, and dissemination (PED) of data from multiple national security and commercial satellites

Lower-latency multi-sensor fusion for terrestrial or Space threat detection and tracking

AI/ML and Large Language Models (LLM) to enable real-time and autonomous or semi-autonomous decision making for satellites and other space assets

Earth-independent endpoint detection and response (EDR) capabilities to enhance the cyber security of the thousands of national security, commercial, and civil space assets

ODC Nodes 1 and 2 will be part of the Kepler Communications optical relay network constellation scheduled to launch by the end of the year. Axiom Space and Kepler Communications have been collaborating since 2023 on the integration of Optical Intersatellite Links (OISLs) with Axiom Space’s ODCs to enable high-speed data connections directly between ODCs and commercial and government spacecraft and networks on-orbit.

These ODC Nodes will feature high-speed, 2.5 Gbps-capable optical links to other Kepler Communications optical relay assets in LEO or other satellites, constellations and spacecraft that are compatible with the Space Development Agency’s (SDA) Tranche 1 optical communications standards. Data transfer will also be possible between the ground and the ODC nodes via optical or radio frequency links. SDA-compatible optical communications terminals will make these initial ODC nodes, and future nodes, interoperable with national security, other government, and commercial satellite networks.

Axiom Space will have options to purchase additional payloads on Kepler’s constellation to increase ODC capacity. The two companies will jointly collaborate on extending network and ODC services to national security, civil, commercial, and international customers.

As the rapid development of digital technology, driven by the proliferation and adoption of AI/ML, continues to transform industries, the limitations of terrestrial data centers — such as energy consumption, cooling, real estate, regulatory licensing and permitting, and exposure to human or natural disruptions — are becoming increasingly apparent, globally. Axiom Space is at the forefront of mitigating these challenges by developing a modular and scalable network of ODC nodes that will offer enhanced global digital sovereignty, security, and resilience to customer data and AI/ML needs, doing so by leveraging the abundant energy and domain of space.

Looking ahead, Axiom Space is committed to expanding its Docs network in the years to come, significantly increasing capacity and capability from kilowatts to megawatts of processing power on-orbit to provide customers with a viable alternative to resource-intensive terrestrial data centers.

We have been developing ODC capabilities since 2022with the launch of an AWS Snowcone to the International Space Station (ISS), followed by an array of demonstrations in Earth-independent cloud solutions from the station,” said Jason Aspiotis, global director of in-space data and security, Axiom Space. “In 2023, we announced our initial plans for an ODC Tranche 1 on Axiom Station, and in March, we shared news of the launch of a prototype data processing unit – AxDCU-1 – with Red Hat to the ISS this spring. ODC Nodes 1 and 2 are an acceleration of our plans to deploy a multitude of free-flyer ODC nodes in LEO to meet the rapidly emerging demand from users around the world, especially for defense applications where real-time, and cyber and quantum-secure data processing, AI/ML, and autonomous decision-making solutions are critically needed.”

Aspiotis continued, “Free-space optical communications have come a long way in the past few years, with significant investments by commercial entities, the Department of Defense, and NASA in advancing OISL capabilities. We plan to integrate emerging 10Gbps+ OISL and space-to-ground optical communications capabilities into our future ODC nodes, as they become available to facilitate connections to more satellites, more constellations, more ground sites, and ultimately Tbps-worth of data flow in the foreseeable future.”

Kam Ghaffarian, CEO, Executive Chairman, and Co-founder of Axiom Space, said, “Our ODC nodes will soon be open for business. We have agreements in place with users around the world to deploy initial, space-based cloud services, not just demonstrations of capabilities. We are also closely monitoring national security needs, especially the U.S. Golden Dome initiative, and how our evolving ODC infrastructure can support U.S. and allied capabilities in space-based data storage, processing, cybersecurity, and AI/ML. ODCs are integral to Axiom Space’s vision of era-defining space infrastructure, unlocking transformational capabilities and economic growth.”

Rocket Lab USA, Inc. (Nasdaq: RKLB) has expanded the company’s suite of space-grade radio frequency (RF) communications systems, the Frontier radios—they are flight-proven, software-defined and designed for reliable telemetry, tracking, and command (TT&C).

Adapted from the Johns Hopkins University Applied Physics Laboratory’s Frontier Lite radio, Rocket Lab’s high-performance Frontier radios have over 13 years of flight heritage and are now available in L-, S-, C-, X-, and Ka-band models. The radio is designed from the ground up for reliable and secure communications to support any orbit or space environment and have advanced capabilities like ranging waveforms for radiometric navigation. Frontier radios are compact and lightweight for easy integration onto any satellite.

As part of Rocket Lab’s vertically integrated subsystems and components, Frontier radios are compatible with the Deep Space Network and other global ground stations, including the Near Earth Network, Air Force Satellite Control Network, KSAT, SSC, Viasat, and other commercial networks.

This RF product suite is a further expansion of Rocket Lab’s component products, joining a portfolio that includes reaction wheels, star trackers, solar power systems, flight software, ground software, separation systems, and more.

Frontier radios are flight-proven across a range of missions including Rocket Lab’s Photon Pathstone, three Rocket Lab Pioneer spacecraft for Varda Space Industries, NASA’s CAPSTONE, NASA’s Europa Clipper, NASA’s Solar Probe Plus, Emirates Mars, and Van Allen Probes. Upcoming, Rocket Lab’s Frontier L-band radio will be used for Viasat to support their hybrid space communications network demonstrations for NASA’s Communications Services Project.

The Frontier Radio was also selected as a 2024 R&D 100 Award for innovations pushing the boundaries of research and development.

We are excited to add this suite of software-defined radios to our expanding portfolio of products,” said Brad Clevenger, Vice President of Rocket Lab Space Systems.  “We continue to demonstrate our ability to deliver high reliability, high performance products at constellation scale.  While much of the industry struggles with supply chain challenges, Rocket Lab continues to demonstrate that it is the right partner for merchant component supply to the most demanding missions.”

Fraunhofer IIS has now researched a splitting method that allows satellites of different classes to be integrated into the 5G network—despite that shortcoming.

With 5G, communication on the ground is to merge with space for the first time to form non-terrestrial networks, in which satellites can completely take over the role of base stations. However, the technical challenges to be resolved are enormous: the existing mobile communications standards are not designed to allow signals to cover thousands of kilometers with the associated latency.

Although the satellites themselves are increasingly being equipped with intelligent on-board processors, they are still reaching their performance limits.

Fraunhofer IIS has successfully demonstrated in the lab how satellites can be integrated into mobile communications, even if their performance falls short. To do this, the researchers split a 5G base station in half, so that only part of the signal processing is moved into space while the rest remains on the ground. This allows the satellites to be active players in the network and support wireless communications while minimizing the use of computing power, energy, and resources.

For the experiment, Fraunhofer IIS used a channel emulator to realistically recreate the extreme conditions of space. This made it possible to simulate the connection to a geostationary satellite located at an altitude of 36,000 kilometers. Fraunhofer IIS used the DVB-S2X satellite communication standard to connect the base station and link the two split components together. Finally, part of the base station ran on a commercially available field-programmable gate array (FPGA), which could conceivably be used on future satellites.

After all, the industry is focused on building cost-effective satellites with robust and energy-efficient components,” said Rainer Wansch, Head of the RF and SatCom Systems Department at Fraunhofer IIS. “Our splitting method opens the door to new and more complex architectures,” Wansch says. That’s because splitting makes it possible to distribute and design functions and tasks variably across different satellite orbits and performance classes. This is particularly relevant for the development of future 6G mobile communications, which are set to integrate not only satellites but also airborne platforms such as drones or aircraft.”

This demonstration of the splitting method is Fraunhofer IIS’s contribution to the TRANTOR project, which the European Commission is funding to prepare the transition of satellite communications from 5G to 6G. By consistently integrating satellites into mobile networks, research and industry hope to create a dense and universally available communications network that is highly resilient, even in crisis situations.

Fraunhofer IIS is currently working on this in numerous other research projects; it’s also involved in 5G standardization through its role on the 3rd Generation Partnership Project (3GPP). Last year, the research institute was appointed to the Steering Board of the newly founded NTN Forum of the European Space Agency (ESA). 

SpinLaunch has selected Kongsberg NanoAvionics (‘KONGSBERG’) as its exclusive satellite supplier for their LEO broadband communication constellation, Meridian Space—the parties have signed a contract for the delivery of 280 of these smallsats, worth 122.5 million euros.

The Meridian Space constellation is taking a fundamentally new approach to space-based broadband by combining a series of advanced technologies never before deployed in a commercial satellite constellation. The partnership includes two prototypes as well as the development and serial production of 280 satellites.

NanoAvionics and SpinLaunch will develop a prototype satellite optimized for higher performance and launch efficiency. The approximately 70 kg satellites for this project are much lighter than currently operational SATCOM platforms, enabling significant performance advantages per kilogram. The unique design combined with the high-performance avionics and payload will allow these satellites to deliver uninterrupted global connectivity with terabits-per-second capacity in a single rocket launch. 

As part of the transaction, Kongsberg Defence & Aerospace has acquired a minority stake in SpinLaunch to support the commercialization of Meridian’s pioneering SATCOM solution. This partnership underscores both organizations’ commitment to delivering affordable and sustainable space services worldwide.

Over time, SpinLaunch plans to grow the Meridian constellation to 1,200 satellites, as originally outlined in the company’s 2021 spectrum filings. To meet the needs of the 280-satellite constellation production schedule, Kongsberg NanoAvionics will ramp up its manufacturing capabilities with the addition of a new assembly and testing facility at its European headquarters in Vilnius, Lithuania. 

The Meridian Space solution, supported by KONGSBERG, will offer significantly higher broadband capacity in a satellite constellation compared with what is available on the market today,” said Eirik Lie, President of Kongsberg Defence & Aerospace. “KONGSBERG’s decision to partner with SpinLaunch reflects our belief in their innovative approach to satellite communications.”

Our supply contract for Meridian is a clear example of how Kongsberg NanoAvionics enables complex satellite missions with standardized, scalable technology,” said Atle Wollo, CEO of Kongsberg NanoAvionics. 

Kongsberg NanoAvionics brings a strong track record in small satellite manufacturing that aligns well with our goal of bringing a highly differentiated satcom constellation to market,” said David Wrenn, CEO of SpinLaunch. ”Together, we are taking meaningful steps towards providing a low-cost, reliable, high-speed broadband service to global enterprises.” 

The United States Space Force (USSF) awarded Northrop Grumman Corporation (NYSE: NOC) two national security contracts, including a technology demonstration for in-space refueling—these contracts build on Northrop Grumman’s proven, on-orbit satellite servicing and refueling innovation, including first-of-its-kind mission extension services that protect critical space assets in geosynchronous orbit for both U.S. government and commercial partners.

• Space Systems Command (SSC) awarded Northrop Grumman a contract for the Elixir refueling payload program, which will enable the Space Force to refine tactics and procedures for rendezvous and proximity operations, docking, refueling, and undocking of on-orbit vehicles – foundational capabilities for servicing, mobility and logistics.
• Under the Elixir program contract, the company will design, build and integrate a refueling payload onto a space vehicle and demonstrate refueling with a demonstration client satellite.
• Under a separate contract, Northrop Grumman has been awarded a multi-unit award of four of the company’s proven ESPAStar spacecraft, one of which will host the refueling demonstration payload on its ride to space.

The USSF has made a multi-unit ESPAStar purchase, underscoring the increasing demand for rideshare vehicles and rapid access to space. Since its first award in 2016, the ESPAStar product line has provided proven and reliable capability. Each upgraded bus can hold more than 330kg of payload mass on each of its six ports, providing additional mass-to-orbit.

The Elixir program includes elements to successfully perform rendezvous and proximity operations, dock and undock with a demonstration client satellite, to transfer and receive fuel. The refueling payload will be equipped with the company’s Active Refueling Module (ARM), which interfaces with Northrop Grumman’s Passive Refueling Module (PRM) for the transfer and receipt of fuel. Operational client satellites equipped with PRMs will benefit from this mature technology because they can be refueled.

In 2023, the company’s PRM was approved by SSC’s Space Systems Integration Office (SSIO) as a refueling interface for consideration by SSC programs. Multiple PRM flight units are currently in production for the Space Force and will also be integrated onto Northrop Grumman’s next-generation satellite servicing vehicle, the Mission Robotic Vehicle.

The in-orbit demonstration will advance and validate the company’s on-orbit servicing and refueling technology – paving the way for fully operational refueling spacecraft in the future. These developments follow years of work by Northrop Grumman across commercial and U.S. government contracts to mature all elements of key refueling technologies and mission architecture.

Lauren Smith, program manager, in-space refueling, Northrop Grumman, said, “This technology will unlock new possibilities for dynamic space operations, providing the sustained maneuverability our customers need in a complex environment. To deliver this critical national security capability, our team will build on Northrop Grumman’s in-space servicing success and trailblaze new refueling solutions to meet mission needs.”

Matt Verock, vice president, space security systems, Northrop Grumman, said, “Northrop Grumman’s refueling capabilities are pioneering the next generation of satellite technology. The ability to refuel on orbit will have a direct impact on the success of our nation’s most important missions – allowing warfighters to continue operating quickly and safely.”

The U.S. Space Force (USSF’s) Space Systems Command (SSC) awarded Firm Fixed-Price (FFP), Indefinite-Delivery Indefinite-Quantity (IDIQ) National Security Space Launch (NSSL) Phase 3 Lane 1 contracts to Rocket Lab USA, Inc. and Stoke Space, joining Blue Origin, SpaceX and United Launch Alliance (ULA) who were on-ramped to Lane 1 last year.

Rocket Lab and Stoke Space will each receive a $5 million FFP Task Order to conduct an initial capabilities assessment and develop their approach to tailored mission assurance. Tailored mission assurance is a tiered approach to the government’s breadth and depth of the launch vehicle baseline understanding and the associated risks to the mission.

Assured Access to Space executes the U.S. Space Force’s Core Competency of Space Mobility and Logistics. It secures reliable and responsive launch services to deploy the space-based capabilities needed by our Nation’s warfighters, intelligence professionals, decision makers, allies, and partners.

Additionally, it operates and sustains resilient and ready launch and test infrastructure to project on-orbit warfighting capability through all phases of conflict and to expand US economic, technological, and scientific leadership. Further, Assured Access to Space delivers servicing, mobility, and logistics capabilities that operate in, from, and to the space domain.

The next opportunity for providers to on-ramp their emerging systems to the Lane 1 IDIQ contract will occur in the first quarter of fiscal year 2026.

With today’s award, the Space Force expanded our portfolio of launch systems able to deliver critical space capability. These new partners bring innovative approaches and increased competition to our mission area,” said Brig. Gen. Kristin Panzenhagen, USSF program executive officer for Assured Access to Space. “Our Lane 1 goal is to bring in new partners to increase capacity, resiliency, and speed.”

We are excited to bring on new launch providers to the NSSL Phase 3 Lane 1 contract and I’m extremely proud of the team’s hard work on-ramping Rocket Lab and Stoke Space as soon as they were ready,” said Lt. Col. Douglas Downs, SSC’s materiel leader for Space Launch Procurement. “We climbed a tall mountain to execute this source selection quickly, and we’re not done yet. We look forward to on-ramping more emerging companies over the next few years as their systems become read. Once Rocket Lab and Stoke Space complete their first successful launch, they will be eligible to compete for launch service task orders on Lane 1. We will release Requests for Proposals (RFPs) for additional Lane 1 launch services later this spring, and we also have several more missions we will compete in FY26.”

SSC is the U.S. Space Force’s field command responsible for acquiring and delivering resilient warfighting capabilities to protect our nation’s strategic advantage in and from space. SSC manages a $15.6 billion space acquisition budget for the DoD and works in partnership with joint forces, industry, government agencies, and academic and allied organizations to accelerate innovation and outpace emerging threats. Our actions today are making the world a better space for tomo
