In a significant step toward establishing permanent infrastructure around the Moon, Tokyo-based space startups ArkEdge Space has officially selected Dawn Aerospace to provide the propulsion technology for its next-generation lunar navigation satellite. According to an official press release from Dawn Aerospace, the company will supply its flight-proven green chemical propulsion systems to maneuver the new spacecraft.

This satellite development is part of a major contract awarded to ArkEdge Space by the Japan Aerospace Exploration Agency (JAXA) to establish a Lunar Navigation Satellite System (LNSS). The LNSS mission serves as a critical building block for the international “LunaNet” initiative, a collaborative effort spearheaded by NASA, the European Space Agency (ESA), and JAXA to build sustainable communication and navigation networks for lunar exploration.

As human habitation and economic activities expand toward the Moon under the Artemis program, the need for reliable, autonomous navigation is paramount. We are seeing a distinct shift from direct Earth-to-Moon tracking toward dedicated lunar satellite networks, and this partnership highlights the global supply chain forming to meet these new technical demands.

Building the Lunar Navigation Satellite System (LNSS)

The foundation of this mission was laid in December 2024, when JAXA selected ArkEdge Space under its Space Strategy Fund to lead the development of advanced lunar navigation technology. Industry reports indicate that ArkEdge Space’s LNSS development is supported by up to 5 billion yen (approximately $32.5 million USD) over a four-year period.

Under this initiative, ArkEdge is tasked with developing a 100 kg-class micro-satellite that will serve as a demonstration platform for lunar positioning and navigation. A primary technological innovation of the ArkEdge mission involves capturing faint Global Navigation Satellite System (GNSS) signals from Earth. By utilizing these signals, which were originally designed for terrestrial use, the satellite will accurately determine its position and time while operating in lunar orbit, roughly 380,000 kilometers away.

The Role of LunaNet and Lunar PNT

Positioning, Navigation, and Timing (PNT) services are essential for the safe and autonomous operation of lunar rovers, landers, and base habitats. Currently, lunar navigation relies heavily on direct Earth-to-Moon tracking, a method that is both expensive and difficult to scale as the number of lunar missions increases.

The LNSS is Japan’s direct contribution to the broader LunaNet architecture. A dedicated lunar satellite network will allow for real-time, high-accuracy positioning. According to mission parameters detailed in industry research, the system is targeting less than 40 meters of horizontal accuracy near the lunar South Pole, a region of high interest for future crewed landings and resource extraction.

The Shift Toward Sustainable Spaceflight

To navigate the complex orbital mechanics required for the LNSS mission, ArkEdge Space turned to Dawn Aerospace. Founded in 2017 with roots in the Netherlands and New Zealand, Dawn Aerospace specializes in scalable, sustainable space mobility.

Dawn Aerospace will supply its flight-proven green chemical propulsion systems for ArkEdge Space’s upcoming lunar satellite.

According to the company’s press release, Dawn’s propulsion technology utilizes non-toxic propellants, specifically nitrous oxide and propylene. This selection highlights a growing industry trend toward sustainable spaceflight. Traditional satellite propulsion often relies on highly toxic chemicals like hydrazine. By utilizing “green” bipropellant systems, space companies can ensure safer handling, significantly reduce ground processing costs, and align with broader environmental sustainability goals.

Company Track Records

Both companies bring substantial momentum to the LNSS project. As of early 2026, Dawn Aerospace reports having over 175 thrusters launched into orbit, providing propulsion for at least 42 operational satellites. The company currently employs over 130 staff across the Netherlands, New Zealand, France, and the United States.

ArkEdge Space, founded in 2018 with origins in research at the University of Tokyo, specializes in the design and mass production of micro-satellite constellations. The company employs approximately 181 people and has secured significant capital to fund its deep space ambitions, including an 8 billion yen (approximately $51.8 million USD) Series B funding round closed in early 2025.

AirPro News analysis

The collaboration between ArkEdge Space and Dawn Aerospace is a prime indicator of the rapid globalization of the “Lunar Economy.” Historically, deep space infrastructure was the exclusive domain of massive, state-owned defense contractors. Today, we are witnessing a Japanese micro-satellite startup and a Dutch-New Zealand propulsion company collaborating to build foundational, GPS-like infrastructure for the Moon.

Furthermore, the integration of green propulsion into deep space missions is no longer just an environmental preference; it is becoming a logistical necessity. As launch cadences increase, the high costs and hazardous material protocols associated with hydrazine are becoming prohibitive for agile startups. Dawn Aerospace’s flight-proven green thrusters provide the necessary delta-v for lunar orbit insertion without the operational bottlenecks of legacy toxic fuels.

Firefly Aerospace has announced a strategic collaboration with NVIDIA to bring advanced edge AI processing to lunar orbit. According to the company’s press release, this partnership will power “Ocula,” billed as the first commercial lunar imaging and mapping service.

The Ocula service will be deployed on Firefly’s Elytra orbital vehicle during the upcoming Blue Ghost Mission 2, which is targeted for launch no earlier than late 2026. By integrating an NVIDIA Jetson module with Firefly’s proprietary SciTec AI software, the spacecraft will process high-resolution images directly in space.

This on-orbit processing capability aims to bypass traditional deep-space communication bottlenecks, delivering real-time, actionable insights back to Earth rather than transmitting raw, bandwidth-heavy data files.

The Ocula Service and Mission Profile

Hardware and Software Integration

The technological core of the Ocula service relies on high-resolution telescopes provided by the Lawrence Livermore National Laboratory (LLNL). Embedded directly into these telescopes is the NVIDIA Jetson edge AI module, which serves as the primary processing engine for the spacecraft’s optical sensors.

Driving the hardware is AI software developed by SciTec, a subsidiary of Firefly Aerospace. The company notes in its release that these algorithms have already been proven in critical national security missions in Earth orbit, providing a reliable foundation for their deployment in deep space.

Mission Timeline and Expansion

Elytra will initially serve as a transfer vehicle and long-haul communications relay for Firefly’s Blue Ghost lunar lander during Blue Ghost Mission 2. Following these initial duties, Elytra will remain in lunar orbit for approximately five years to operate the Ocula service.

Firefly is already looking beyond this initial deployment. The company is under contract to deploy two additional Elytra vehicles during Blue Ghost Mission 3 and Mission 4. This constellation approach is designed to increase coverage and reduce revisit times over the lunar surface.

Overcoming Deep Space Bottlenecks

Spacecraft equipped with high-resolution optical sensors generate massive volumes of raw data. Historically, transmitting this data back to Earth has been severely hindered by the latency and limited bandwidth of deep-space communication networks.

To solve this issue, the aerospace industry is shifting toward edge computing. By processing data on the spacecraft using AI, the vehicle can analyze raw imagery autonomously and only transmit the most important insights or compressed data back to Earth.

“Modern space missions generate massive volumes of data that require immediate processing to overcome the latency and bandwidth constraints of deep-space communications,” stated Deepu Talla, VP of Robotics and Edge AI at NVIDIA, in the press release. “Integrating the NVIDIA Jetson platform into Firefly’s Elytra spacecraft enables autonomous, on-orbit AI processing that transforms raw lunar imagery into actionable insights in real time.”

Dual-Use Capabilities for Commercial and Defense Sectors

Lunar Mapping and Space Domain Awareness

Ocula is positioned as a dual-use service catering to both commercial and government customers. Its primary capabilities include continuous, high-resolution imaging of the Moon’s surface to identify resources, map terrain, and support future landing missions.

Additionally, the service will provide Space Domain Awareness (SDA). The AI software will fuse multiple data feeds to track maneuvering objects in cislunar space, the area between Earth and the Moon. This autonomous reconnaissance provides critical situational awareness for national security and safe space operations.

“Ocula is set to be the first commercial lunar imaging and mapping service available on the market,” said Jason Kim, CEO of Firefly Aerospace. “Now through our collaboration with NVIDIA, Ocula will be powered by the world’s leading edge AI processor. This capability allows us to layer on our SciTec AI software as the ‘brains’ that give customers real-time data driven insights from the Moon.”

AirPro News analysis

We view this development as a significant milestone in the commercialization of lunar infrastructure. Current government-owned lunar orbiters, such as NASA’s Lunar Reconnaissance Orbiter launched in 2009, are aging and nearing the end of their operational lives. Firefly’s Ocula service steps into a critical market void, offering updated, high-resolution lunar mapping to support the growing number of international and commercial lunar missions.

Furthermore, the emphasis on Space Domain Awareness highlights the growing strategic importance of cislunar space. As the Moon becomes more crowded with international missions, the ability to track maneuvering objects is a major priority for defense agencies like the U.S. Space Force. Firefly’s vertical integration, utilizing its own Elytra spacecraft, Blue Ghost lander, and SciTec software, demonstrates its maturation as an end-to-end space and defense contractor.

On April 1, 2026, NASA’s Artemis II mission successfully launched, sending humans toward the Moon for the first time in over 50 years. As of this writing, the four-person crew is executing the latter half of their historic 10-day journey. At the heart of this mission is the Orion spacecraft, built by Lockheed Martin, which serves as the critical life-support vessel for the astronauts navigating the unforgiving environment of deep space.

According to an official press release from Lockheed Martin, the primary engineering focus of the Artemis II flight is the rigorous validation of Orion’s Environmental Control and Life Support System (ECLSS). This complex network of subsystems is actively keeping the crew alive, healthy, and comfortable as they travel on a hybrid free-return trajectory around the far side of the Moon.

Engineering Human Survival in Deep Space

The ECLSS is described by Lockheed Martin as the “first core function” of the Orion spacecraft. To make this mission a reality, manufacturers faced the monumental task of miniaturizing life support systems, which occupy massive amounts of space on the International Space Station (ISS), to fit within the strict size and mass limits of the Orion capsule without sacrificing efficacy.

Air, Water, and Thermal Control

As detailed in the company’s release, the Air Revitalization System utilizes regenerative chemical scrubbing technology called “amine swing beds” to maintain breathable oxygen, remove carbon dioxide, and control humidity. Crucially, in the event of a pressure vessel leak, this system can provide a pressurized, breathable atmosphere and thermal cooling for four suited astronauts for up to 144 hours.

The spacecraft’s Active Thermal Control System acts much like a car radiator, using coolant fluids and heat exchangers to vent excess heat into space. This ensures the cabin remains at a stable 70 to 75 degrees Fahrenheit, protecting the crew from the extreme temperature fluctuations of deep space and the intense heat of atmospheric reentry. Additionally, the Potable Water System supplies 74 gallons of highly filtered water across four pressurized tanks for drinking, hygiene, and medical needs.

Waste Management and Safety

Orion is equipped with a Universal Waste Management System modeled after the ISS space toilet. According to Lockheed Martin, it utilizes dual fan separators for airflow-assisted collection in microgravity, alongside advanced filtration for odor and particulate control. The spacecraft also features a dedicated hygiene bay for privacy and a microgravity-engineered Fire Detection and Suppression System that continuously monitors for combustion byproducts.

Rigorous Testing for a Historic Mission

Before the April 2026 launch, the ECLSS underwent exhaustive testing to ensure flawless operation in the vacuum of space. Lockheed Martin noted that hardware and “physics-only” tests were conducted at the Orion Life Support Integration Facility (OLIF) at NASA’s Johnson Space Center. Here, engineers simulated vacuum conditions, tested swing-bed seals, and verified pressure and humidity control loops under fault conditions.

Software validation took place at the Integrated Test Lab (ITL) near Denver, Colorado. Engineers ran full-mission simulations, injecting artificial faults, such as sensor noise or stuck valves, to test the system’s automated diagnostics and resolution capabilities.

“The Environmental Control and Life Support System is logically the first core function of Orion. Designing the spacecraft right is starting from the people onboard and working outward,” stated Sean O’Dell, Orion Spacecraft Architect at Lockheed Martin.
