France’s VORTEX Spaceplane Advances Reusable Orbital Systems
Dassault Aviation’s VORTEX program combines military and civilian space capabilities with advanced thermal tech, targeting cost-efficient reusable launches by 2028.
At the 2025 Paris Air Show, Dassault Aviation and the French Ministry of Armed Forces unveiled a pivotal step in France’s aerospace ambitions: the VORTEX spaceplane demonstrator. This initiative marks a significant milestone in Europe’s pursuit of sovereign access to space, blending military and civilian capabilities within a reusable orbital platform. The VORTEX program, short for Véhicule Orbital Réutilisable de Transport et d’Exploration, embodies a dual-use philosophy that aims to redefine the strategic and commercial utility of spaceplanes.
Backed by France’s €6 billion military space investment through 2030, VORTEX is not just a technological demonstrator, it’s a strategic statement. It positions France, and by extension Europe, to compete with global players like the United States and China in the emerging field of reusable space systems. With a global space economy projected to reach $511 billion by 2029, the stakes are high, and the opportunities vast.
Dassault Aviation’s journey toward the VORTEX program is rooted in decades of experience in spaceplane development. The company was a key contributor to the Hermès program, initiated in 1987 by the European Space Agency (ESA), which aimed to create a crewed spaceplane capable of servicing orbital stations. Although the program was canceled in 1992, it laid the groundwork for future advancements in re-entry vehicle design and thermal modeling.
In the 1990s, Dassault collaborated with NASA on the X-38 Crew Return Vehicle, providing flight control systems and parafoil landing technologies. These systems were successfully tested in atmospheric conditions and showcased Europe’s capabilities in autonomous guidance during high-speed re-entries. This collaboration further honed Dassault’s expertise in high-velocity flight dynamics and reentry control.
The most direct precursor to VORTEX was the 2015 Intermediate eXperimental Vehicle (IXV), a lifting-body reentry demonstrator developed by ESA. Dassault led the aerodynamic design and in-flight experimentation, validating ceramic thermal protection systems and hypersonic stability. These experiences provided vital data and technological know-how that now inform the VORTEX development strategy.

The VORTEX initiative follows a four-phase incremental development strategy designed to mitigate risks and validate critical technologies. The first phase, the VORTEX-D demonstrator, is a 1:3 scale model measuring approximately 4 meters in length. It will focus on hypersonic flight control, advanced thermal protection, and autonomous guidance. Its maiden flight is scheduled for 2028 and will simulate full orbital re-entry conditions.
Subsequent phases include the VORTEX-S (2:3 scale) for in-orbit servicing, the VORTEX-C cargo variant, and the VORTEX-M, a crewed vehicle for human spaceflight. Each phase builds on the previous, progressively validating systems and expanding operational capabilities.
Technologically, VORTEX introduces modular thermal protection systems made from silicon-carbide composites reinforced with carbon fibers. These materials offer superior thermal stability above 1,600°C, maintain aerodynamic integrity over multiple flights, and reduce mass by 30% compared to traditional systems. Additionally, active cooling channels integrated into the wing leading edges, adapted from Rafale fighter jet technology, enhance thermal management during reentry. VORTEX exemplifies France’s dual-use space strategy. On the military side, the spaceplane can deploy reconnaissance satellites, retrieve classified payloads, and conduct orbital threat inspections. These capabilities align with the French Military Programming Law (2024–2030), which earmarks €6 billion for space-related defense initiatives.
Civilian applications are equally significant. VORTEX is designed for satellite servicing, microgravity research, and cargo transport to low-Earth orbit (LEO) stations. The satellite servicing market alone is projected to reach $2.4 billion by 2030, offering substantial commercial opportunities. By adopting a flexible design, VORTEX can cater to diverse missions, from pharmaceutical research in microgravity to servicing aging satellites.
This dual-use model not only optimizes development costs but also creates export potential, particularly for emerging space nations seeking turnkey orbital solutions. It mirrors the broader European objective of achieving strategic autonomy while tapping into lucrative commercial markets.
One of the most formidable challenges in reusable spaceplane development is mastering hypersonic flight, particularly during atmospheric re-entry. At speeds between Mach 5 and Mach 25, vehicles face extreme aerodynamic forces and thermal loads. VORTEX-D’s blended-wing-body design is engineered to distribute shockwaves away from control surfaces, enhancing stability and reducing structural stress.
The vehicle uses a hybrid control system: reaction control system (RCS) thrusters for maneuvering in space, and elevon surfaces for atmospheric flight. This approach reduces mass and complexity compared to traditional systems. Computational fluid dynamics (CFD) models, validated by IXV flight data, support the design’s efficacy in managing boundary layer transitions and shockwave interactions.
These innovations are critical to ensuring safe and reliable reentries, a non-negotiable requirement for any reusable orbital system. Success in this domain would place France among the few nations capable of hypersonic vehicle recovery and reuse.
Thermal management is another cornerstone of VORTEX’s design. The thermal protection system (TPS) integrates ceramic matrix composites with embedded sensors for real-time monitoring. Transpiration cooling is employed at stagnation points to reduce localized heating, and self-healing coatings help mitigate damage during reentry.
These features aim to overcome the limitations seen in current systems like NASA’s X-37B, which requires extensive post-flight inspections. VORTEX’s TPS is designed for up to 10 flights between major refurbishments, supported by AI-driven damage assessment tools originally developed for the Rafale fighter jet. Such advancements could dramatically lower operational costs and turnaround times, enhancing the economic viability of reusable spaceplanes for both military and commercial missions.
VORTEX is more than a technological endeavor, it’s a geopolitical tool. It reinforces Europe’s strategic autonomy by reducing reliance on foreign launch providers like SpaceX or Roscosmos. ESA’s 2025 budget allocates 13.3% to space transportation, a category that includes VORTEX development, underscoring its strategic importance.
In the global landscape, VORTEX competes with Sierra Space’s Dream Chaser, Boeing’s X-37B, and China’s reusable spacecraft. Its unique value proposition lies in its modularity and dual-use certification, making it adaptable to a wide range of missions. Market projections suggest demand for over 30 such vehicles by 2040, particularly from European and allied defense agencies.
Financially, VORTEX aims for recurring launch costs of $25 million, significantly lower than current European expendable systems. This is achieved through horizontal integration, modular avionics, and robotic inspection systems. These efficiencies are essential for capturing a share of the growing LEO economy, expected to generate $11.7 billion by 2033.
The VORTEX spaceplane initiative is a bold and calculated step toward European leadership in reusable space technologies. By building on decades of aerospace experience and leveraging substantial government support, France is positioning itself at the forefront of the new space race. The program’s phased development approach, focus on dual-use capabilities, and integration of advanced materials and AI-driven systems provide a solid foundation for success.
Looking ahead, the 2028 flight of the VORTEX-D demonstrator will be a critical milestone. It will validate key technologies and set the stage for full-scale operational deployments by 2031. As international partnerships and commercial opportunities evolve, VORTEX could become a cornerstone of Europe’s strategic and economic presence in space. The program not only reflects France’s aerospace ambitions but also its commitment to shaping the future of orbital mobility and sovereignty.

Lockheed Martin Awarded $1.1B Contract for SDA Tranche 3 Satellites
Lockheed Martin secured a $1.1B contract to build 18 Tranche 3 satellites for the Space Development Agency’s missile tracking and defense network.
This article is based on an official press release from Lockheed Martin.
Lockheed Martin (NYSE: LMT) has been awarded a major contract with a potential value of approximately $1.1 billion by the Space-Agencies (SDA). Announced on December 19, 2025, the agreement tasks the aerospace giant with producing 18 space vehicles for the Tranche 3 Tracking Layer (TRKT3) constellation. These satellites are a critical component of the Proliferated Warfighter Space Architecture (PWSA), a network designed to detect, track, and target advanced missile threats, including hypersonic systems.
This award represents a significant portion of a broader $3.5 billion investment by the SDA, which simultaneously issued Contracts to Rocket Lab, Northrop Grumman, and L3Harris. Together, these companies will construct a combined total of 72 satellites. According to the announcement, Lockheed Martin’s specific allotment of satellites is scheduled for launch in Fiscal Year 2029.
Under the terms of the agreement, Lockheed Martin will deliver 18 missile warning, tracking, and defense space vehicles. Unlike traditional legacy programs that often take a decade to field, the SDA operates on a rapid “spiral development” model, fielding new generations, or “tranches”, every two years. Tranche 3 is particularly significant as it represents the “Sustained Capability” generation, designed to replenish and replace earlier satellites while introducing advanced fire-control capabilities.
The satellites will be manufactured at Lockheed Martin’s SmallSat Processing & Delivery Center in Colorado. The company confirmed that Terran Orbital will continue to serve as a key supplier, providing the satellite buses. This continuation of the supply chain partnership aims to maintain production stability across the various tranches.
A defining feature of the Tranche 3 Tracking Layer is the inclusion of “fire-control quality” tracking. While previous iterations focused primarily on warning and tracking, half of the payloads in this new constellation are designated for missile defense. This means the satellites can generate data precise enough to guide an interceptor to destroy a threat, rather than simply monitoring its trajectory.
“The Tracking Layer of Tranche 3… will significantly increase the coverage and accuracy needed to close kill chains against advanced adversary threats. The constellation will include a mix of missile warning and missile tracking, with half the constellation’s payloads supporting advanced missile defense missions.”
Gurpartap “GP” Sandhoo, Acting Director, Space Development Agency
With this latest award, Lockheed Martin’s total backlog with the SDA has grown to 124 space vehicles across multiple tranches. This reinforces the company’s position as a dominant player in the rapid-acquisition space sector. The SDA’s strategy involves splitting awards among multiple vendors to foster competition and reduce industrial base risk. The $3.5 billion total funding for Tranche 3 was distributed as follows:
Lockheed Martin and Rocket Lab received higher contract values, which industry analysts attribute to the complexity of the defense-specific payloads included in their respective lots.
“Lockheed Martin’s ongoing investments and evolving practices demonstrate our commitment to supporting the SDA’s Proliferated Warfighter Space Architecture. These innovative approaches position Lockheed Martin to meet the warfighter’s urgent need for a proliferated missile defense constellation.”
Joe Rickers, Vice President of Transport, Tracking and Warning, Lockheed Martin
The awarding of the Tranche 3 contracts highlights a pivotal shift in U.S. defense strategy toward “proliferated” architectures. By deploying hundreds of smaller, cheaper satellites rather than a handful of large, expensive targets (“Big Juicy Targets”), the U.S. Space Force aims to increase resilience against anti-satellite weapons. If an adversary destroys one node in a mesh network of hundreds, the system remains operational.
Furthermore, the explicit mention of “fire-control quality tracks” signals that the PWSA is moving from a passive observation role to an active engagement support role. This is a direct response to the development of hypersonic glide vehicles by peer adversaries, which fly too low for traditional ground-based Radar-Systems to track effectively. The reliance on Terran Orbital for satellite buses also underscores the critical nature of supply chain continuity; as production rates increase to meet the two-year launch cycles, prime contractors are prioritizing established supplier relationships to minimize delay risks.

Venturi Space Completes Driving Tests for MONA-LUNA Lunar Rover
Venturi Space successfully tests MONA-LUNA lunar rover at ESA’s LUNA facility, validating key mobility and wheel tech for a 2030 Moon mission.
This article is based on an official press release from Venturi Space.
Venturi Space has announced the successful completion of the first driving tests for its MONA-LUNA lunar rover. Conducted at the European Space Agency’s (ESA) newly inaugurated LUNA analog facility in Cologne, Germany, these tests mark a pivotal step in Europe’s roadmap toward autonomous lunar exploration. The rover, designed to be “100% European,” demonstrated its capability to navigate loose regolith and steep inclines, validating key technologies intended for a targeted 2030 mission to the Moon’s South Pole.
According to the company’s announcement, the tests focused on mobility, obstacle traversal, and the durability of onboard electronic systems under simulated lunar conditions. The successful campaign confirms the viability of Venturi’s proprietary wheel technology and sets the stage for further development leading up to integration with the European Argonaut lander.
The testing campaign took place at the LUNA facility, a joint operation by ESA and the German Aerospace Center (DLR) that opened in September 2024. The facility features a 700-square-meter hall filled with 900 tonnes of regolith simulant, volcanic powder derived from the Eifel region, designed to mimic the surface of the Moon. The environment also replicates the unique lighting conditions of the lunar South Pole, providing a high-fidelity testing ground for robotic systems.
Venturi Space reports that the MONA-LUNA rover exceeded initial performance targets during these Test-Flights. Specifically, the vehicle successfully climbed slopes of up to 33 degrees and navigated large rocky obstacles without losing traction. A primary objective was to verify that the rover would not sink into the loose soil, a common hazard in lunar exploration.
A critical component validated during these tests was the rover’s “hyper-deformable” wheel technology. Invented by Venturi, these wheels are designed to absorb shocks and maximize the contact patch with the ground, providing necessary grip on soft, unstable surfaces. Dr. Antonio Delfino, Director of Space Affairs at Venturi Space, emphasized the importance of this validation.
“The main objective… was to validate the rover’s mobility in conditions representative of a lunar surface, with a particular focus on the interaction between its hyper-deformable wheels and a highly realistic regolith simulant.”
Dr. Antonio Delfino, Venturi Space
The MONA-LUNA is engineered to serve as a logistics and exploration vehicle capable of surviving the harsh lunar environment. According to technical details released by Venturi Space, the rover weighs approximately 750 kg, with the capacity to extend to 1,000 kg depending on specific mission payloads. It is capable of speeds up to 20 km/h (approximately 12.4 mph). The vehicle is electrically powered, utilizing solar panels and three high-performance batteries. Crucially, the rover is built to endure the extreme thermal variations of the lunar cycle, with a stated operating range of -240°C to +110°C. It is equipped with a robotic arm for scientific tasks and is designed to carry cargo or, in emergency scenarios, an astronaut.
The development of MONA-LUNA represents a strategic shift toward European independence in space logistics. Currently, much of the global lunar infrastructure relies on non-European Partnerships. By developing a sovereign rover capable of launching on an Ariane 6 rocket and landing via the European Argonaut lander (developed by Thales Alenia Space), Europe is securing its own access to the lunar surface.
This autonomy is further supported by Venturi’s industrial expansion. The company plans to open a new 10,000-square-meter facility in Toulouse, France, by 2028. This factory will employ approximately 150 engineers dedicated to the Manufacturing of the MONA-LUNA, signaling a long-term industrial commitment beyond the initial prototype phase.
While the MONA-LUNA is targeted for a 2030 launch, Venturi Space has outlined an incremental approach to technology validation. Before the full-sized rover reaches the Moon, a smaller “sister” rover named FLIP (FLEX Lunar Innovation Platform) is scheduled to launch in 2026.
Developed in partnership with the U.S. company Venturi Astrolab, FLIP will fly on a commercial mission with Astrobotic. This earlier mission will serve as a “pathfinder,” testing the same batteries and wheel technologies in the actual lunar environment four years before the MONA-LUNA mission. Gildo Pastor, President of Venturi Space, expressed confidence in the current progress following the Cologne tests.
“Seeing MONA LUNA operate on the legendary LUNA site is a profound source of pride… We know we have only completed 1% of the journey that, I hope, will take us to the Moon.”
Gildo Pastor, President of Venturi Space
The successful completion of these driving tests at the LUNA facility confirms that the foundational mobility technologies required for Europe’s 2030 lunar ambitions are now operational in a relevant environment.

Skyroot Aerospace Sets Launch Window for Vikram-1 Orbital Rocket
Skyroot Aerospace prepares for Vikram-1’s maiden orbital launch in early 2026 from Sriharikota, focusing on tech validation with reduced payload.
This article summarizes reporting by India Today and Sibu Tripathi.
Skyroot Aerospace, India’s pioneering private space technology firm, has commenced final preparations for the maiden orbital launch of its Vikram-1 rocket. According to reporting by India Today, the launch vehicle has been transported to the Satish Dhawan Space Centre (SDSC) in Sriharikota, with the company targeting a Launch window within the next two months.
This mission marks a critical transition for the Hyderabad-based company, moving from suborbital demonstration to full orbital capability. While the primary goal is reaching Low Earth Orbit (LEO), company leadership has emphasized that the inaugural flight is primarily a validation exercise for their proprietary technology.
As of mid-December 2025, the first stage of the Vikram-1 rocket has arrived at the spaceport in Sriharikota. India Today reports that integration and assembly operations are currently underway at the launch site. Skyroot co-founder Bharath Daka indicated that all subsystems are expected to be ready within approximately one month, followed by a final round of validation checks.
Based on this timeline, the launch is projected to occur in early 2026 (January or February). This schedule aligns with the company’s rapid development pace following the inauguration of their new Manufacturing facility, the Infinity Campus, in November 2025.
Maiden flights of new orbital class rockets carry significant risk, a reality Skyroot leadership is openly acknowledging. To mitigate potential losses, the rocket will carry a reduced payload. India Today notes that the vehicle will fly with approximately 25% of its maximum payload capacity to de-risk the mission.
While orbital insertion is the ultimate objective, the company has set incremental benchmarks for success. Speaking to India Today, Bharath Daka emphasized that surviving the initial phases of flight would be a major technical victory.
“We will consider the mission a meaningful achievement even if the rocket simply clears the launch tower,” Daka told India Today.
In addition to clearing the tower, the engineering team is focused on the vehicle surviving “Max-Q”, the point of maximum aerodynamic pressure, and successfully executing stage separation. These milestones provide critical data for future iterations, regardless of whether the final orbit is achieved on the first attempt. The Vikram-1 represents a significant leap in complexity compared to its predecessor, the Vikram-S, which completed a suborbital test flight in November 2022. Unlike the single-stage suborbital demonstrator, Vikram-1 is a multi-stage launch vehicle designed for the commercial small satellite market.
The upcoming launch of Vikram-1 is a bellwether event for the Indian private space sector. Following the government’s liberalization of the space industry, Skyroot’s progress serves as a test case for India’s ability to foster a commercial ecosystem parallel to the state-run ISRO. If successful, Vikram-1 will position India as a competitive player in the global small satellite launch market, challenging established entities like Rocket Lab. The decision to lower public expectations by focusing on “clearing the tower” is a prudent communication Strategy, common among launch providers facing the high statistical failure rates of debut flights.
