L3Harris Nears $500M Sale of Space Propulsion Stake to AE Industrial
L3Harris is selling a 60% stake in its space propulsion assets, including the RL-10 engine, to AE Industrial Partners for $500 million, supporting its focus on missile defense.
This article summarizes exclusive reporting by Reuters and journalist Mike Stone.
L3Harris Technologies is reportedly in advanced negotiations to sell a controlling interest in its space propulsion portfolio to private equity firm AE Industrial Partners. According to exclusive reporting by Reuters, the defense contractor aims to divest a 60% stake in assets that include the RL-10 rocket engine, a critical component for United Launch Alliance (ULA) vehicles.
The deal, which sources told Reuters could be announced as early as January 5, 2026, values the stake at approximately $500 million. This transaction implies a total enterprise value of roughly $845 million for the propulsion unit. The move appears to be part of a broader strategy by L3Harris to reshape its portfolio toward national security priorities, specifically the Pentagon’s emerging missile defense initiatives.
According to the reporting, the agreement is structured as a partial divestiture rather than a complete exit. L3Harris is expected to retain a 40% minority interest in the new entity, while AE Industrial Partners will take the controlling 60% share. Reuters notes that the proceeds from the sale, expected to exceed $500 million, will be utilized by L3Harris to pay down debt and invest in capacity for solid rocket motor production.
The transaction is anticipated to close in the second half of 2026, pending regulatory approvals. This structure allows L3Harris to maintain a financial foothold in the commercial launch sector while freeing up capital for its core defense contracts.
The decision to sell these assets highlights a significant strategic pivot for L3Harris. Reuters reports that the company is realigning its resources to capitalize on the “Golden Dome” initiative, a multi-layered missile defense architecture proposed by the administration in 2025.
By shedding commercial and NASA-centric lines, L3Harris aims to position itself as a prime contractor for the high-priority national security programs required to build this shield against hypersonic and ballistic threats. The capital raised from the sale is reportedly earmarked for expanding missile manufacturing capabilities, directly supporting this shift in defense posture.
The deal involves a specific segmentation of L3Harris’s propulsion capabilities, largely acquired during its purchase of Aerojet Rocketdyne in 2023. AE Industrial Partners is set to acquire the “Propulsion Portfolio,” which includes assets vital to the commercial space supply chain:
Conversely, Reuters indicates that L3Harris will keep the RS-25 rocket engine program. As the core stage engine for NASA’s Space Launch System (SLS), this asset is tied to long-term government contracts for the Artemis program, fitting the company’s preference for stable, government-backed revenue streams.
For AE Industrial Partners, this acquisition represents a major step toward vertical integration in the space sector. The firm already holds a significant portfolio of space companies, including launch provider Firefly Aerospace and infrastructure firm Redwire.
Acquiring the RL-10 engine provides AE Industrial with a “crown jewel” component that powers competitor rockets, effectively securing a revenue stream from the broader launch market while bolstering its internal capabilities. Reuters suggests this move consolidates critical launch capabilities under one private equity roof, potentially creating a new “super-integrator” to rival traditional prime contractors.
The reported sale underscores a growing trend where private equity firms are stepping in to manage legacy space hardware that traditional defense primes no longer view as core to their growth strategies. For L3Harris, the logic is clear: the margins and growth potential in the “Golden Dome” missile defense architecture likely outweigh the steady but slower-growing commercial propulsion market.
However, the transfer of the RL-10 engine, a single point of failure for U.S. national security launch, to a private equity-backed entity will likely draw scrutiny. Industry observers will be watching closely to see if AE Industrial prioritizes production stability and R&D investment for this workhorse engine, or if financial engineering takes precedence. If successful, AE Industrial could effectively control a significant portion of the Western launch supply chain, supplying engines to the very companies its other portfolio assets compete against.

NASA and SpaceX Schedule Early Return of Crew-11 from ISS
NASA and SpaceX target January 14, 2026, for Crew-11’s early return from the ISS due to a medical concern, marking the first medical evacuation in ISS history.
This article is based on an official press release.
NASA and SpaceX have officially set a target date for the return of the Crew-11 mission, marking a significant and historic moment for operations aboard the International Space Station (ISS). According to the agency, the four-person crew is scheduled to undock no earlier than 5 p.m. EST on Wednesday, January 14, 2026, pending favorable weather conditions.
The early return is necessitated by a medical concern involving one of the crew members. While NASA has confirmed the individual is in stable condition, the agency has opted to bring the crew home approximately one month ahead of their original schedule. This event marks the first time in the 25-year history of the ISS that a mission has been cut short specifically to facilitate a medical evacuation.
The SpaceX Dragon capsule Endeavour is currently docked at the ISS, awaiting departure. If the schedule holds, the timeline for the return operation is as follows:
The crew launched on August 1, 2025, and upon splashdown, they will have spent approximately 167 days in orbit. The decision to return early truncates a mission originally slated to conclude in February or March.
NASA officials emphasized that the schedule remains “pending weather conditions.” Strict safety criteria govern the splashdown of the Dragon capsule. Recovery teams require wind speeds to be less than 10 mph (approximately 8.7 knots) and specific wave height limits to ensure the structural integrity of the heat shield and the safety of the recovery personnel. Additionally, the recovery zone must be free of rain, lightning, or thunderstorms to allow for safe helicopter operations.
The returning Crew-11 team consists of four astronauts representing three international space agencies:
NASA has maintained strict confidentiality regarding the specific medical issue, citing privacy policies aligned with HIPAA principles. However, the agency has been clear that this is a “precautionary” measure rather than an immediate emergency evacuation. The affected crew member is stable, but flight surgeons determined that returning to Earth for advanced medical care was the prudent course of action.
“NASA and SpaceX are targeting no earlier than 5 p.m. EST, Wednesday, Jan. 14, for the undocking… pending weather conditions.”
, NASA Official Statement
Prior to this development, the crew had been preparing for a spacewalk scheduled for January 8 to install solar array hardware. That operation was cancelled on January 7 as the medical concern emerged. The departure of Crew-11 will leave the ISS with a significantly reduced staff until the arrival of Crew-12, which is not scheduled until mid-February. Following the undocking, only three crew members will remain on board:
With the station operating on a skeleton crew, U.S.-led spacewalks are effectively suspended, as these operations typically require more support personnel than will be available. The remaining trio is expected to prioritize essential station maintenance over new scientific experiments during this interim period.
While the medical evacuation presents a logistical challenge, it also serves as a critical validation of NASA’s contingency protocols. As the agency prepares for the Artemis missions to the Moon and future expeditions to Mars, the ability to execute a rapid, unplanned return is a vital capability.
This event acts as a real-world “stress test” for deep-space exploration medical protocols. Unlike the ISS, where a return to Earth can be executed in under 24 hours, a mission to Mars would not offer such an option. Data gathered from this evacuation will likely influence the design of future medical kits and telemedicine procedures for missions where immediate return is impossible.

Elon Musk Targets 10,000 Starships Annual Production at SpaceX
Elon Musk sets a goal for SpaceX to produce 10,000 Starships per year, exceeding current aerospace manufacturing rates to support Mars colonization.
This article summarizes reporting by Yahoo Finance and Badar Shaikh.
SpaceX CEO Elon Musk has outlined a production goal for the Starship rocket that would dwarf the output of the world’s largest commercial aircraft manufacturers. According to reporting by Yahoo Finance, Musk confirmed on the social media platform X (formerly Twitter) that the company aims to manufacture Starships at a scale previously unseen in the aerospace industry.
The statement, made on January 4, 2026, came in response to a discussion regarding SpaceX’s potential to ramp up manufacturing to levels comparable to commercial aviation. Musk’s response suggested that the company is targeting a future where rockets are built with the frequency of jetliners.
In the exchange on X, Musk engaged with a hypothesis suggesting SpaceX could eventually mirror the production rates of major aircraft manufacturers. As reported by Yahoo Finance, Musk validated this theory, indicating that the long-term strategy involves “massive volume.”
“Yes, at massive volume. Maybe as high as 10,000 ships per year.”
, Elon Musk, via X (as reported by Yahoo Finance)
This figure represents a significant escalation in SpaceX’s public targets. While Musk has previously discussed building a fleet of 1,000 Starships to facilitate Mars colonization, the specific mention of annual production at the 10,000-unit mark implies a continuous Manufacturing engine rather than a static fleet buildup.
To understand the scale of Musk’s 10,000-unit target, it is necessary to look at current aerospace benchmarks. For context, the global commercial aviation industry, led by Boeing and Airbus, produces significantly fewer units annually.
Data regarding aircraft production rates in 2024 and 2025 indicates that the Boeing 737 program targets approximately 450 to 600 aircraft per year. Similarly, the Airbus A320 family generally sees production rates between 600 and 900 units annually. Musk’s target of 10,000 rockets per year would effectively require a production rate 10 to 15 times higher than the combined output of the world’s two most prolific commercial jet programs. Furthermore, the supply chain implications are immense. A full Starship stack, comprising the Super Heavy booster and the Ship, utilizes approximately 39 Raptor engines. Achieving an annual output of 10,000 ships would theoretically demand the production of nearly 390,000 rocket engines per year, a figure that exceeds current global jet engine production capabilities.
The primary motivation behind this extreme production target appears to be the logistical requirements of establishing a self-sustaining city on Mars. Musk has frequently cited a goal of transporting one million tons of cargo and personnel to the Red Planet to ensure the colony’s survival.
Because the orbital alignment between Earth and Mars allows for efficient travel only once every 26 months, a massive fleet must be ready to launch in rapid succession during these narrow windows. A production rate of 10,000 units annually suggests a strategy that accounts for rapid fleet expansion, high attrition rates, or the potential use of Starship hulls as raw construction materials upon arrival at Mars.
While the ambition is clear, the logistical hurdles remain substantial. Current environmental assessments and launch licenses, such as those for the Starbase facility in Texas, limit launch frequency to a fraction of this target. Scaling to 10,000 annual units would likely require:
As of early 2026, SpaceX produces Starship prototypes at a rate of approximately one every two to three weeks, or roughly 20 per year.
Elon Musk has stated that a self-sustaining city on Mars requires transporting one million tons of cargo. Achieving this within a reasonable timeframe requires a massive fleet launching during the brief Earth-Mars transfer windows that occur every 26 months.
Currently, no aerospace manufacturer produces complex vehicles at that volume. For comparison, the Boeing 737 and Airbus A320 programs combined produce fewer than 1,500 aircraft per year.

SpaceX Lowers Starlink Satellites for Safer Orbital Operations
SpaceX plans to lower 4,400 Starlink satellites to 480 km orbit to reduce debris and improve space safety throughout 2026.
This article summarizes reporting by Ars Technica.
In a significant operational shift aimed at long-term orbital sustainability, SpaceX has announced plans to lower the altitude of approximately 4,400 Starlink satellites. According to reporting by Ars Technica, the company will transition these satellites from their current orbit of roughly 550 kilometers down to approximately 480 kilometers throughout 2026. The move is designed to enhance space safety and reduce the risk of long-term orbital debris.
The reconfiguration affects the entire first-generation shell of the constellation and potentially early second-generation units. SpaceX officials have stated that this maneuver is being “tightly coordinated” with the Federal Communications Commission (FCC) and U.S. Space Command to ensure traffic management remains stable during the transition.
The primary driver behind this decision is the interaction between solar cycles and atmospheric density. As explained by Michael Nicolls, VP of Starlink Engineering, the sun follows an 11-year cycle that directly impacts the Earth’s upper atmosphere. We are currently approaching a “solar minimum,” expected around 2030, during which the atmosphere cools and contracts.
In a statement cited by Ars Technica, Nicolls noted that during a solar minimum, the atmosphere at 550 km becomes significantly thinner, reducing the drag on satellites. Consequently, a defunct satellite at that altitude could remain in orbit for more than four years before naturally burning up. By lowering the fleet to 480 km, SpaceX ensures the satellites operate in a denser atmospheric layer.
“At 480 km, the atmosphere is denser… a failed satellite… would decay in just a few months.”
Summary of remarks by Michael Nicolls via Ars Technica
This “self-cleaning” characteristic is critical for preventing the accumulation of space junk. If a satellite fails at the new lower altitude, atmospheric drag will force it to deorbit and burn up much faster, regardless of the solar cycle.
Beyond the solar cycle, the move addresses immediate congestion issues in Low Earth Orbit (LEO). The 500–600 km orbital shell has become the most crowded region in LEO, hosting thousands of active satellites and debris fragments. By shifting operations to 480 km, SpaceX aims to place its fleet in a less populated region. The decision also follows a specific technical incident. According to the provided reports, a Starlink satellite experienced an anomaly in December 2025, venting propellant and creating a field of trackable debris. Operating at a lower altitude serves as a mitigation strategy for such events; should similar failures occur in the future, the resulting debris would clear from orbit rapidly rather than posing a threat for years.
Moving the constellation requires a careful balance of operational parameters. Flying at a lower altitude increases atmospheric drag, which demands more fuel for “station-keeping” to maintain orbit. However, reports indicate that SpaceX is confident its ion thrusters possess sufficient propellant to manage this increased load without significantly reducing the satellites’ lifespan.
There are also potential benefits to service quality and astronomy:
This reconfiguration represents a proactive step in “responsible stewardship” that may set a new standard for mega-constellation operators. By voluntarily accepting the “fuel penalty” of a lower, drag-heavy orbit, SpaceX is prioritizing safety over maximum operational lifespan. This move could pressure competitors, such as Amazon’s Project Kuiper or China’s Guowang, to adopt similar “self-cleaning” orbital architectures.
Furthermore, this adjustment appears distinct from SpaceX’s future plans for “Very Low Earth Orbit” (VLEO) satellites, which are intended to operate even lower at 300–350 km. The shift to 480 km effectively creates a bridge between traditional LEO operations and the ultra-low orbits targeted for future direct-to-cell connectivity.
