Northrop Grumman Tests NASA BOLE Rocket Booster in Utah
Northrop Grumman’s BOLE booster achieves 4M lbs thrust in Utah test, advancing Artemis missions with composite tech despite nozzle anomaly.
On June 26, 2025, Northrop Grumman conducted a full-scale static fire test of NASA’s Booster Obsolescence and Life Extension (BOLE) solid rocket booster in Promontory, Utah. This test marked a major milestone in the evolution of solid rocket propulsion, showcasing the most powerful segmented solid rocket motor ever built for human spaceflight. Producing over 4 million pounds of thrust, the 156-foot booster is a critical component in advancing NASA’s Artemis program and future deep-space missions.
BOLE represents a significant evolution from the Space Launch System (SLS) boosters, integrating a carbon-fiber composite case, updated propellant formulation, and advanced control systems. These innovations aim to enhance performance, reduce weight, and address the obsolescence of legacy components. While the test encountered an anomaly near the end of the burn, the data collected is expected to refine future designs and improve reliability for upcoming Artemis missions.
This article explores the technical advancements, test outcomes, economic context, and strategic implications of the BOLE booster, offering a comprehensive look at its role in shaping the future of human space exploration.
One of the most notable changes in the BOLE booster is the transition from a steel casing to a carbon-fiber composite structure. This shift reduces the overall weight by approximately 15%, allowing for better thrust-to-weight ratios and increased payload capacity. The new casing, developed using sand-mandrel technology, offers enhanced structural integrity under high-pressure conditions and streamlines manufacturing through automation.
By leveraging composite materials, Northrop Grumman aligns BOLE with commercial aerospace standards, promoting interoperability across government and private-sector programs. The integration of U.S.-sourced metallic components also strengthens domestic supply chains, reducing reliance on obsolete parts and foreign suppliers.
These structural innovations not only improve performance but also support long-term sustainability in booster production. The lighter, more resilient casing is crucial for supporting missions that demand high payload capacities, such as lunar habitat modules or Mars-bound cargo.
“The carbon fiber composite case enables better booster performance, faster manufacturing, and aligns with commercial standards by providing commonality among our infrastructure, supply chain, and manufacturing operations.” — Northrop Grumman
BOLE’s updated propellant formulation includes a high-energy mix of ammonium perchlorate, aluminum powder, and PBAN (polybutadiene acrylonitrile) binder. This composition increases energy density by about 12% compared to the SLS Block 1 boosters, allowing for more efficient combustion and higher thrust output.
Complementing the propellant upgrades is the introduction of an electronic thrust vector control (eTVC) system. Unlike traditional hydraulic actuators, the eTVC uses electromechanical drives to adjust the nozzle direction with millisecond precision. This system enhances flight stability and trajectory control, especially during critical phases such as liftoff and stage separation. These propulsion and control advancements are derived from Northrop Grumman’s previous work on the OmegA rocket and other defense systems, emphasizing the cross-application of proven technologies. As a result, BOLE represents a fusion of legacy reliability and cutting-edge innovation.
The June 2025 test, designated Development Motor 1 (DM-1), aimed to validate BOLE’s integrated systems under full-scale conditions. Over 700 data channels monitored thermal, structural, and combustion parameters during the two-minute burn. Initial results were promising: the booster achieved over 4 million pounds of thrust and maintained structural integrity for most of the test duration.
However, at around 110 seconds into the burn, an anomaly occurred involving the nozzle’s carbon-carbon throat insert. High-speed footage showed debris ejecting from the nozzle, followed by asymmetric flame patterns. The nozzle eventually disintegrated, though the motor continued firing until shutdown at 140 seconds.
Post-test analysis attributed the failure to thermal erosion triggered by localized propellant segregation. Despite the anomaly, 92% of test objectives were achieved, including successful validation of the composite casing and eTVC system. The incident provides critical data for refining nozzle design and improving propellant casting processes.
“While the motor appeared to perform well through the most harsh environments of the test, we observed an anomaly near the end… This test provides us with valuable data to iterate our design for future developments.” — Jim Kalberer, VP, Propulsion Systems, Northrop Grumman
BOLE development is funded through NASA’s $3.19 billion Booster Production and Operations Contract (BPOC) awarded in 2021. This contract supports booster production for Artemis IV-VIII and the development of BOLE for Artemis IX and beyond. Each BOLE unit is estimated to cost around $336 million, a notable reduction from the $470 million cost of earlier SLS boosters.
The cost savings are attributed to supply chain consolidation, automated manufacturing, and design standardization. However, challenges remain. NASA’s Office of Inspector General has reported cost overruns in RS-25 engine production, which may offset some of the savings from BOLE.
Overall, the BOLE program is projected to cost $4.8 billion through 2035, including design iterations and anomaly resolution. These investments reflect NASA’s commitment to maintaining a domestic solid motor industrial base and supporting high-performance launch capabilities for deep space missions.
BOLE’s operational debut is scheduled for Artemis IX, tentatively planned for 2033. Earlier Artemis missions will continue using legacy five-segment boosters derived from the Space Shuttle program. The transition to BOLE is contingent on resolving the nozzle anomaly and completing additional tests by 2027. Each BOLE booster adds approximately five metric tons of payload capacity to lunar orbit, a critical enhancement for assembling infrastructure like the Lunar Gateway. However, delays in BOLE readiness could impact the Artemis schedule, potentially affecting timelines for Mars mission preparations.
NASA officials acknowledge the complexity of aligning booster development with mission cadence. The program must balance technical progress with budgetary constraints and evolving policy priorities, especially amid discussions about scaling back the SLS program after Artemis III.
BOLE enters a competitive global market for heavy-lift propulsion. Europe’s P120C solid booster, used in Ariane 6, and India’s S200 booster for LVM3 offer alternative approaches with varying cost and performance trade-offs. While BOLE leads in segmented motor thrust, its high cost per kilogram to orbit, estimated at $5,000, limits its commercial viability compared to reusable systems like SpaceX’s Falcon Heavy.
Nonetheless, BOLE’s technology could be adapted for other applications, such as tactical missiles or planetary cargo missions. Its composite casing and eTVC systems are scalable and may support future hybrid launch architectures combining solid and liquid propulsion.
Strategically, BOLE strengthens the U.S. position in solid propulsion technology, supporting thousands of jobs and preserving industrial capabilities critical to national security and space exploration.
The BOLE booster test marks a significant step in the evolution of solid rocket propulsion. Despite the nozzle anomaly, the test validated key innovations in materials, propellant, and control systems. These advancements promise enhanced payload capacity and improved manufacturing efficiency, supporting NASA’s long-term exploration goals.
Looking ahead, the success of BOLE depends on resolving technical issues, securing sustained funding, and aligning with broader space policy objectives. If fully realized, BOLE could extend the capabilities of the SLS program into the 2040s and facilitate human missions to the Moon, Mars, and beyond.

Bureau 1440 Launches 16 Rassvet Satellites for Russian Internet Network
Bureau 1440 launched 16 satellites for the Rassvet constellation, advancing Russia’s sovereign broadband satellite internet with plans for commercial service in 2027.
This article summarizes reporting by Bloomberg News.
On March 23, 2026, the Russian private aerospace company Bureau 1440 successfully launched 16 broadband internet satellites into low-Earth orbit (LEO). According to reporting by Bloomberg News, this deployment represents an early operational step for a network designed to provide global high-speed connectivity.
The satellites, which form the foundation of the “Rassvet” (Dawn) constellation, were carried into space aboard a Soyuz-2.1b rocket at 8:24 p.m. Moscow time. Following separation from the launch vehicle, the spacecraft successfully reached their reference orbit. Industry research data indicates that the satellites are currently under the control of Bureau 1440’s Mission Control Center, undergoing onboard system checks before utilizing their own Propulsion to maneuver into their final target orbits.
This Launch marks a critical transition for Russia’s sovereign satellite internet ambitions, moving the project from experimental prototypes to serial production. As Moscow prioritizes independent orbital infrastructure, the Rassvet network is being positioned as a direct competitor to existing Western systems.
…a low-Earth orbit network that Russian officials have cast as a domestic version of SpaceX’s Starlink. The newly deployed Rassvet satellites are built on a proprietary platform developed by Bureau 1440. According to technical specifications outlined in recent industry reports, the spacecraft integrate a 5G Non-Terrestrial Network (NTN) communications system designed to deliver low-latency internet access globally.
A standout feature of the constellation is its use of next-generation satellite-to-satellite laser communication terminals. This technology enables direct data transfer between spacecraft, facilitating seamless global coverage without a strict reliance on ground stations. Previous orbital tests of this laser technology achieved data transfer rates of up to 10 Gbps over distances exceeding 1,000 kilometers. Additionally, the satellites utilize plasma propulsion units for orbital maneuvering and feature upgraded power supply systems.
Bureau 1440, founded in 2020 as part of ICS Holding (IKS Holding), has moved rapidly through its development phases. The March 2026 launch occurred exactly 1,000 days after the company began its transition from experimental prototypes to serial production. Prior to this operational batch, the company deployed six experimental satellites during the Rassvet-1 and Rassvet-2 test missions in 2023 and 2024, which successfully validated the 5G and laser link technologies.
The financial scope of the Rassvet project is substantial. Industry estimates place the total cost of creating the low-orbit constellation at approximately 445 billion rubles, or roughly $4 to $5 billion USD. Bureau 1440 plans to invest around 329 billion rubles of its own capital through 2030. To support this sovereign initiative, the Russian government has earmarked between 102.8 billion and 116 billion rubles in subsidies and preferential loans to offset development and launch costs. While originally scheduled for late 2025, the deployment of these first 16 operational satellites sets the stage for a planned commercial broadband service launch in 2027. To achieve continuous global coverage, Bureau 1440 aims to have over 250 satellites in orbit by that time. Long-term projections from Roscosmos suggest the constellation could expand to approximately 900 satellites by 2035.
The strategic importance of a sovereign satellite internet network has grown significantly for Moscow. The service is intended to provide connectivity for remote areas, transportation sectors including aviation and railways, heavy industry, and government services, thereby reducing reliance on foreign infrastructure.
While initially framed as a civilian and commercial project, the military and security implications are profound. Following restrictions on the Russian military’s use of Starlink terminals during the conflict in Ukraine, developing an independent, domestic alternative became an urgent national security priority for the Russian government.
We observe that while the successful deployment of 16 serial satellites is a notable milestone for Russia’s private space sector, the scale of the Rassvet constellation remains nascent compared to its primary competitor. SpaceX currently operates thousands of active Starlink satellites in LEO. As space analyst Vitaly Egorov has noted in industry discussions, Bureau 1440 will need to drastically increase its launch cadence to truly rival Starlink’s coverage and capacity.
Furthermore, the commercial viability of the Rassvet network will heavily depend on the company’s ability to mass-produce affordable ground terminals for end-users. This logistical and Manufacturing hurdle has historically challenged new entrants in the satellite broadband market, and overcoming it will be just as critical as maintaining a steady launch schedule.
Bureau 1440 is a private Russian aerospace firm founded in 2020. Operating as part of ICS Holding, the company is focused on developing and deploying a domestic low-Earth orbit broadband satellite constellation.
The company launched 16 serial production communication satellites on March 23, 2026, aboard a Soyuz-2.1b rocket.
Bureau 1440 plans to begin offering commercial broadband services in 2027, by which time it aims to have over 250 satellites in orbit to ensure continuous global coverage.

Artemis II Launch with Real-Time Orion Tracking in April 2026
NASA and Lockheed Martin enable real-time tracking of the Artemis II Orion spacecraft, launching no earlier than April 2026 for a crewed lunar flyby mission.
This article is based on an official press release from Lockheed Martin, supplemented by NASA mission updates and third-party research reporting.
As the aerospace community counts down to the historic launch of the Artemis II mission, space enthusiasts worldwide are preparing to follow the journey closer than ever before. Scheduled for no earlier than April 2026, Artemis II represents the first crewed mission to the Moon’s vicinity since the Apollo 17 mission in December 1972. To bridge the gap between deep space and the public, NASA and its industry partners have introduced unprecedented digital tracking capabilities.
According to an official feature release from Lockheed Martin, the prime contractor for the Orion Crew Module, and supplementary mission data from NASA, the Artemis Real-time Orbit Website (AROW) will provide continuous, real-time telemetry to the global public. We at AirPro News recognize this initiative as a significant leap in public engagement, transforming how audiences interact with crewed spaceflight during its 10-day journey.
The AROW platform, accessible via web browsers and the official NASA mobile application, visualizes data directly from the sensors aboard the Orion spacecraft. As outlined in mission documentation, this telemetry is relayed through the Mission Control Center at NASA’s Johnson Space Center in Houston.
Tracking is slated to begin approximately one minute after liftoff and will continue uninterrupted until the spacecraft’s atmospheric reentry. According to NASA’s published tracking metrics, users will be able to monitor Orion’s exact coordinates, its distance from both the Earth and the Moon, mission elapsed time, and current velocity. This level of transparency allows the public to verify the spacecraft’s progress at every phase of the flight.
Beyond standard web tracking, the NASA mobile app incorporates an augmented reality (AR) tracker. Once the Orion spacecraft separates from the Space Launch System (SLS) upper stage, users can calibrate their smartphones to locate the spacecraft’s exact position in the sky relative to their location on Earth.
Furthermore, NASA is releasing open-source flight data, including state vectors and ephemeris trajectories. According to third-party reporting by outlets such as CNET and Primetimer, this open-data approach empowers software developers, educators, and astronomy enthusiasts to build custom 3D animations, independent physics models, and personalized tracking applications using their own telescopes.
As of mid-March 2026, the Artemis II mission is in its final preparatory phases. Following a series of technical evaluations, including resolutions to a liquid hydrogen leak, helium flow issues, and investigations into the Orion heat shield from the uncrewed Artemis I flight, NASA has targeted a launch window opening no earlier than April 1, 2026. On March 18, 2026, the four-person crew officially entered quarantine in Houston, a standard health protocol prior to spaceflight. According to NASA’s schedule, engineers planned the rollout of the integrated SLS rocket and Orion spacecraft to Launch Pad 39B at the Kennedy Space Center in Florida for the evening of March 19, 2026.
The mission will carry four astronauts: NASA Commander Reid Wiseman, NASA Pilot Victor Glover, NASA Mission Specialist Christina Koch, and Canadian Space Agency Mission Specialist Jeremy Hansen. During the 10-day flight test, the crew will execute a lunar flyby, traveling at least 5,000 nautical miles past the far side of the Moon. This trajectory, supported by the Lockheed Martin-built Crew Module and the Airbus-manufactured European Service Module, will carry humans deeper into space than any previous mission.
As noted in comprehensive mission research reports regarding the flight’s purpose:
“The primary goal is to test Orion’s life support, environmental controls, and communication systems with humans aboard in a deep-space environment.”
The introduction of AROW and AR tracking tools marks a stark contrast to the Apollo era, where public consumption was largely limited to grainy television broadcasts and delayed radio updates. By democratizing deep-space telemetry, NASA and Lockheed Martin are not merely sharing data; they are actively cultivating a new generation of space advocates. We view this interactive strategy as a critical component for sustaining long-term public interest and funding. Maintaining this momentum will be essential as the Artemis program pivots toward establishing a sustained presence at the lunar south pole and, eventually, launching crewed missions to Mars.
The public can track the Orion spacecraft in real-time using the Artemis Real-time Orbit Website (AROW) at nasa.gov/trackartemis, or by downloading the official NASA mobile app, which includes an augmented reality (AR) tracking feature.
Following final preparations and rollout procedures in mid-March 2026, NASA is currently targeting a launch window that opens no earlier than April 1, 2026.
The Orion Crew Module was built by Lockheed Martin, while the European Service Module (ESM), which provides power and propulsion, was manufactured by Airbus.

FAA Streamlines Commercial Space Licensing with Part 450 Rule
The FAA consolidates four regulations into the Part 450 rule, simplifying commercial space launch licensing for major operators by 2026.
This article is based on an official press release from the Federal Aviation Administration (FAA).
The Federal Aviation Administration (FAA) has officially transitioned all commercial space launch and reentry licensing to a single, streamlined regulatory framework known as the Part 450 rule. According to a recent press release from the agency, this move consolidates four legacy regulations into one comprehensive standard, aiming to support the rapid innovation of the American commercial space sector.
By shifting to this unified rule, the FAA intends to provide aerospace companies with greater flexibility and multiple pathways for compliance. The agency noted in its announcement that the updated framework is designed to significantly reduce both administrative and financial burdens on the industry and the regulatory body itself.
The transition marks the end of a five-year grace period during which both the old and new regulations were simultaneously active. This overlap allowed established operators ample time to adapt their licensing strategies to the new performance-based requirements before the final deadline.
Under the newly enforced Part 450 rule, commercial space operators will experience a reduction in the frequency of required FAA license approvals. The agency’s press release highlighted that companies can now obtain a single license to cover an entire portfolio of operations. This includes accommodating different vehicle configurations, varying mission profiles, and even operations across multiple launch and reentry sites.
The regulatory overhaul was initially introduced in March 2021. Since the rule first took effect, the FAA reports that it has issued 14 Part 450 licenses to various operators. The consolidation of four previous rules into this single framework represents a major shift toward performance-based regulation rather than prescriptive mandates.
“We’re pleased to have flight-ready operators and vehicles successfully transition to a performance-based rule that unlocks flexibility while maintaining safety for the public,” said Dr. Minh A. Nguyen, Deputy Associate Administrator for the FAA’s Office of Commercial Space Transportation, in the agency’s press release.
Major players in the commercial space industry successfully met the regulatory deadline to transition their legacy licenses. According to the FAA, the cutoff date for this transition was March 9, 2026.
The agency confirmed that several prominent aerospace companies and their respective launch vehicles have fully adopted the Part 450 framework. The list of transitioned operators includes Blue Origin with its New Shepard vehicle, Firefly Aerospace’s Alpha, and Rocket Lab’s Electron. Additionally, SpaceX transitioned its Falcon 9, Falcon Heavy, and Dragon vehicles, while United Launch Alliance updated the licenses for its Atlas and Vulcan rockets. We view the full implementation of the Part 450 rule as a critical milestone for the U.S. commercial space industry. As launch cadences increase and vehicle designs become more diverse, a fragmented regulatory system with four separate rules was increasingly unsustainable. By allowing a single license to cover multiple sites and vehicle configurations, the FAA is effectively removing bureaucratic bottlenecks that could have otherwise delayed launch schedules. The successful transition of legacy vehicles from industry leaders like SpaceX, Blue Origin, and United Launch Alliance indicates that the sector is well-prepared to operate under this modernized, performance-based safety standard.
The Part 450 rule is a consolidated regulatory framework established by the FAA that governs commercial space launch and reentry licensing. It replaces four older rules to streamline the approval process and offer greater flexibility to aerospace operators.
According to the FAA, operators were required to transition their legacy licenses to the new Part 450 framework by March 9, 2026, concluding a five-year transition period.
The FAA stated in its press release that it has issued 14 Part 450 licenses since the rule initially took effect in March 2021.
