SpaceX Launches Vast’s Haven Demo Paving Way for Private Space Stations
SpaceX launched 18 satellites including Vast’s Haven Demo, advancing private space stations as ISS nears retirement and LEO commercial use grows.
In the early hours of November 2, 2025, a SpaceX Falcon 9 rocket lit up the Florida sky, embarking on a mission that signifies another steady step in the commercialization of space. The launch, designated Bandwagon-4, carried 18 satellites into orbit, but one payload in particular captured the industry’s attention: the “Haven Demo.” This pathfinder satellite, operated by California-based aerospace company Vast, represents a critical milestone in the journey toward a new generation of private space stations, a future that is rapidly approaching as the venerable International Space Station (ISS) nears its scheduled retirement.
We are witnessing a fundamental shift in how humanity accesses and utilizes low Earth orbit (LEO). For decades, space was the exclusive domain of government agencies. Today, private enterprises are not just participating; they are leading the charge. With the ISS set to deorbit around 2030, a void is opening for commercial platforms to take its place, offering services for in-orbit research, manufacturing, and tourism. This launch is a tangible piece of that unfolding narrative, showcasing the synergy between launch providers like SpaceX and ambitious visionaries like Vast.
Enabling this new ecosystem are programs like SpaceX’s “Bandwagon” rideshare missions. These missions function like a cosmic carpool, offering cost-effective and regular launch opportunities for a diverse array of customers. By packing multiple satellites onto a single rocket, SpaceX dramatically lowers the barrier to entry, allowing Startups, research institutions, and international agencies to deploy their technology in space without the prohibitive cost of a dedicated launch. The Bandwagon-4 mission is a perfect illustration of this model in action, carrying payloads for clients from around the globe.
The mission itself was a textbook execution for SpaceX, a company that has made orbital launches a routine affair. The Falcon 9 rocket lifted off from Cape Canaveral Space Force Station in Florida at 1:09 a.m. EDT, marking the company’s 140th Falcon 9 launch of 2025. This relentless launch cadence underscores the maturity of SpaceX’s operations and its central role in the modern space industry.
A key element of SpaceX’s success is its focus on reusability. Approximately eight minutes after liftoff, the Falcon 9’s first stage booster descended back to Earth, executing a flawless landing at Landing Zone 2 at Cape Canaveral. This was the third successful flight and landing for this particular booster, a testament to the reliability and cost-effectiveness of the reusable rocket system that has revolutionized the launch industry. Each landing is not just a spectacle; it’s a critical component of a business model that makes missions like Bandwagon-4 economically viable.
Beyond the headlining Haven Demo, the rocket carried 17 other satellites, painting a vivid picture of the current global space economy. The manifest was a mosaic of international and commercial interests. The payload cluster included the Korea 425 satellite for South Korea’s Agency for Defense Development (ADD) and a host of spacecraft managed by the Berlin-based company Exolaunch. Exolaunch orchestrated the deployment of 13 satellites for eight different international clients from nations including Argentina, Czechia, Finland, the Netherlands, Türkiye, and the United States.
These satellites serve a wide range of functions, from Earth observation and Internet of Things (IoT) connectivity to advanced technology demonstrations. Among them were two weather radar satellites, Tomorrow-R3 and Tomorrow-R4, part of a planned constellation for real-time global precipitation monitoring. Another, Starcloud-1, carried an Nvidia H100 GPU to test the feasibility of in-space data centers, which could offer significant cost and environmental benefits. This diverse payload highlights how access to space is enabling innovation across countless sectors.
While every satellite on the Bandwagon-4 mission has its own objective, the Haven Demo stands out for its role in a much larger, more audacious plan. Operated by Vast, a company founded in 2021 by Jeb McCaleb, this small satellite is the vanguard for what could become the first standalone private space station in history. The primary purpose of the Haven Demo is to serve as a technology pathfinder. It is designed to test the essential systems that will be required for its much larger successor, Haven-1. This mission allows Vast to validate its designs in the harsh environment of space, reducing the risk associated with the full-scale station. It’s a prudent, iterative approach to one of the most complex engineering challenges imaginable.
By testing these components in orbit, Vast can gather invaluable data and refine its technology before committing to the multi-million dollar launch of the station itself. This strategy of “testing as you fly” has become a hallmark of the new space era, enabling companies to move faster and more efficiently than the government-led programs of the past.
The first step in our iterative approach towards building next-generation space stations, Haven Demo will test critical systems for Haven-1, including propulsion, flight computers and navigation software.
The data gathered from Haven Demo will feed directly into the final development of Haven-1, which Vast aims to launch as early as the second quarter of 2026, also aboard a SpaceX Falcon 9. If successful, it will mark a historic moment, establishing the first private commercial outpost in LEO. The station is designed to support a crew of four for up to 30 days and will feature a microgravity research facility, a viewing dome, and continuous internet via Starlink. This project has also garnered the support of NASA, which is providing technical expertise as part of its strategy to foster a commercial LEO ecosystem.
Vast’s ambitions, however, extend far beyond Haven-1. The company’s ultimate goal is to build large-scale space stations that can generate their own artificial gravity. This is considered a crucial technology for enabling long-term human presence in space, as it would mitigate the negative health effects of prolonged exposure to microgravity. Haven-1 is merely the first step. It is envisioned as a precursor to a larger, modular station called Haven-2, and eventually, a massive 100-meter-long artificial gravity station in the 2030s.
If we stick to our plan, we will be the first standalone commercial LEO platform ever in space with Haven-1, and that’s an amazing inflection point for human spaceflight.
The successful launch of the Bandwagon-4 mission is far more than a single event. It is a clear and powerful signal of the direction in which the space industry is heading. We are seeing the maturation of a new ecosystem where launch providers enable a host of specialized companies to pursue innovative and ambitious goals in orbit. The mission perfectly encapsulates the symbiotic relationship between SpaceX’s reliable, cost-effective launch services and the pioneering spirit of companies like Vast.
As the data from Haven Demo is analyzed and progress on Haven-1 continues, we are moving closer to a future where LEO is a bustling hub of commercial activity. The coming decade promises a transformation in how we conduct research, manufacture goods, and even travel, with private space stations at the heart of this new orbital economy. This launch was another small, but essential, step in expanding humanity’s presence in the cosmos.

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.
