Virgin Galactic Spaceship Apeiron Arrives at Spaceport America
Virgin Galactic’s Delta-class Spaceship Apeiron completed its delivery flight to Spaceport America on October 28, 2026.
Virgin Galactic Holdings, Inc. (NYSE: SPCE) has transitioned its lead next-generation Delta-class spacecraft from assembly to flight testing, flying the newly named Spaceship Apeiron to its operational base in New Mexico on October 28, 2026.
The delivery flight, detailed in a company press release, marks a critical milestone for the aerospace manufacturer as it prepares to resume commercial suborbital space tourism in early 2027 following the retirement of its previous generation of vehicles.
Delivery and naming of Spaceship Apeiron
The spacecraft, mated to the VMS Eve launch vehicle, departed Phoenix-Mesa Gateway Airport in Arizona at 10:29 a.m. MST. It arrived at Spaceport America in Truth or Consequences, New Mexico, at 12:59 p.m. MDT. The flight crew for the delivery included Pilot in Command Michael Masucci, Pilot Dan Alix, and Flight Test Engineer Tori Crichton.
Prior to the flight, Virgin Galactic revealed the spacecraft’s name. “Apeiron,” an ancient Greek word translating to “boundless,” was selected through a public vote that drew participants from more than 80 countries.
“This morning, we gave Apeiron a name. This afternoon, Apeiron came home,” Virgin Galactic Chief Executive Officer Michael Colglazier said in the release. “Seeing the ship fly beneath Eve to Spaceport America was a moment years in the making.”
Transitioning to the Delta-class fleet
The arrival of Spaceship Apeiron at Spaceport America shifts the company’s focus entirely to the Delta-class program. Virgin Galactic retired its previous SpaceShipTwo-class vehicle, VSS Unity, on June 8, 2024. According to reporting by Flying Magazine, VSS Unity completed 12 spaceflights, seven of which were commercial missions, before the company halted operations to redirect resources toward developing the larger Delta-class fleet.
The new spacecraft design addresses the capacity and turnaround limitations of its predecessor. Flying Magazine notes that the Delta-class vehicles will carry six passengers, an increase from the four-passenger capacity of VSS Unity. The new fleet is also engineered to support a flight cadence of up to twice a week.
Demand for suborbital flights remains steady despite rising costs. Digital Trends reports that Virgin Galactic currently charges $750,000 per seat, with approximately 700 ticket holders in the queue for future flights. In the broader space tourism market, Virgin Galactic operates with limited direct suborbital competition heading into 2027. Space.com notes that competitor Blue Origin has paused flights of its New Shepard rocket to focus on its lunar lander program, while operators like SpaceX focus on multi-day orbital missions at significantly higher price points.
Flight test program and commercial timeline
Spaceship Apeiron will now undergo a comprehensive flight test program at Spaceport America. The testing phase will follow the completion of avionics software integration and system validation.
The timeline for a return to commercial operations has shifted in recent months. In August 2026, Virgin Galactic delayed the expected start of commercial spaceflights from late 2026 to early 2027 to allow additional time for avionics and systems installations across the fleet, according to Space.com. The company now targets early Q2 2027 for the commencement of commercial flights aboard Spaceship Apeiron. A second Delta-class spaceship is expected to enter commercial service in late Q2 or early Q3 2027.
Virgin Galactic plans to provide further program updates during its third-quarter earnings call in November 2026.
AirPro News analysis
The successful delivery of Spaceship Apeiron is a necessary technical milestone, but the financial viability of Virgin Galactic rests entirely on the Delta-class achieving its promised turnaround times. With VSS Unity retired and a backlog of roughly 700 customers waiting for flights, the company faces a critical gap in revenue generation. If the Delta-class can reliably fly twice a week with six passengers at the current $750,000 ticket price, the unit economics of suborbital tourism may finally stabilize. However, the recent schedule slip into 2027 highlights the persistent developmental risks inherent in bringing a new crewed spacecraft into commercial service.

Starfighters Space Plans STARLAUNCH 1 Captive-Carry Flight Test
Starfighters Space schedules a December 2026 captive-carry flight of STARLAUNCH 1 aboard an F-104 Starfighter from Kennedy Space Center.
Starfighters Space, Inc. (NYSE American: FJET) will conduct the first captive-carry flight test of its STARLAUNCH 1 suborbital development vehicle using a Lockheed F-104 Starfighter in December 2026. The mission marks the program’s transition from ground-based design to active flight testing, establishing operational procedures for future drop tests and powered launches.
In a press release issued on October 13, 2026, the company confirmed that the airframe design for STARLAUNCH 1 has been finalized and inert flight hardware has been ordered. The December 2026 flight will originate from the company’s base at the National Aeronautics and Space Administration (NASA) Kennedy Space Center and proceed to the Federal Aviation Administration (FAA) licensed Cecil Spaceport in Jacksonville, Florida.
Transitioning to active flight testing
The upcoming captive-carry flight represents a critical milestone for the STARLAUNCH program. Inert flight hardware is expected to arrive at the Kennedy Space Center hangar in November 2026. Engineering teams will then begin assembly and testing of the rocket-aircraft interface to ensure the Lockheed F-104 Starfighter can safely carry the suborbital vehicle.
Tim Franta, CEO of Starfighters Space, stated that the planned captive-carry flight will move STARLAUNCH 1 from design and ground-based development directly into flight testing.
“Our approach is deliberately incremental: build the hardware, integrate it with the aircraft, fly it, collect data, and use those results to advance toward separation and powered flight. This work on STARLAUNCH 1 is also expected to generate engineering and operational experience to inform the future development of STARLAUNCH 2.”
The December 2026 mission is designed to test aircraft integration, evaluate aerodynamic behavior, and establish operational procedures. Piercarlo Ciacchi, Director of Flight Operations and Chief Pilot of Starfighters Space, noted that the flight will capture essential data for the FAA and the United States Space Force (USSF).
“December’s captive-carry mission would essentially be step one of a multi-flight campaign, building processes for our launch team while capturing data for the FAA and the Space Force as we move toward propulsive air launch.”
Following the December 2026 captive-carry mission, the company plans to conduct a drop test over the Atlantic Ocean. This will be followed by a demonstration of the integrated propulsion system.
Hardware integration and propulsion development
The December 2026 flight may also serve a dual purpose by incorporating hardware from the company’s Wind Tunnel in the Sky program. On October 8, 2026, Starfighters Space announced the completion of its first flight hardware for this initiative, manufactured by Italian engineering firm Robby Moto Engineering S.R.L. (RME). The assembled flight articles measure 3.65 meters in length and 178 millimeters in diameter.
During the STARLAUNCH 1 flight, the company may fly this newly completed Wind Tunnel in the Sky hardware under the opposite wing of the Lockheed F-104 Starfighter on a customer-funded rideshare mission. In this configuration, the hardware will simultaneously serve as an aerodynamic counterweight for the STARLAUNCH 1 vehicle.
Propulsion development is also advancing in parallel. On September 9, 2026, Starfighters Space signed a Memorandum of Understanding with Florida-based Vaya Defense & Space to evaluate the Vortex-Hybrid rocket engine for the STARLAUNCH system. Data collected during the December 2026 flight will support Vaya Defense & Space in developing a hybrid rocket motor aligned with the specific requirements of STARLAUNCH 1.
The STARLAUNCH development pathway
Starfighters Space operates the world’s only commercial fleet of flight-ready Mach 2+ supersonic aircraft. Based at the Kennedy Space Center, the company utilizes its fleet to provide pilot training, in-flight testing, and microgravity research, while actively developing air-launch capabilities for space payloads.
The STARLAUNCH program is the company’s primary air-launch initiative. STARLAUNCH 1 serves as the initial suborbital development vehicle, designed to pave the way for STARLAUNCH 2, a larger vehicle intended for orbital launches.
The program has met several technical milestones throughout the year. On January 21, 2026, the company announced the successful completion of subsonic and supersonic wind tunnel testing for STARLAUNCH 1. These tests demonstrated clean separation behavior at Mach 0.85 and Mach 1.3. Subsequently, on February 20, 2026, the program advanced to a Critical Design Review (CDR) with support from GE Aerospace to confirm design maturity.
Addressing the hypersonic testing bottleneck
The aerospace and defense industries are currently facing a significant bottleneck in hypersonic testing. Traditional ground-based wind tunnels are heavily oversubscribed and typically offer only seconds of test time per run. Airborne platforms like the Lockheed F-104 Starfighter fleet offer sustained testing at speeds exceeding Mach 2 in real atmospheric conditions.
This capability provides a complementary method to compress development timelines for defense primes and commercial space companies, allowing them to gather sustained aerodynamic data outside of traditional laboratory environments.
AirPro News analysis
We view the activation of the STARLAUNCH flight test campaign as a notable indicator of the shifting economics in high-speed aerospace testing. By utilizing legacy supersonic platforms to bypass the constraints of ground-based infrastructure, commercial operators are positioning themselves to capture overflow demand from defense primes and space launch developers. If the December 2026 captive-carry flight successfully validates the aerodynamic integration, it will likely accelerate the timeline for propulsive air-launch systems, offering a viable alternative to traditional vertical launch architectures for smaller payloads.
The dual-use nature of the December 2026 flight, which tests the launch vehicle while simultaneously flying a commercial payload as a counterweight, demonstrates a highly efficient approach to flight test monetization. This strategy allows the operator to offset development costs while proving out multiple distinct business lines on a single sortie.

Space Cargo Unlimited Books SpaceX Starfall for 2028 Mission
Space Cargo Unlimited signs with SpaceX to launch a 1-tonne in-space factory on Starfall in 2028, its first European customer.
Luxembourg-based startups Space Cargo Unlimited has secured a contract with SpaceX to launch a one-tonne modular space factory aboard the new Starfall reentry capsule. The mission, targeted for 2028, marks a significant capacity increase for commercial in-space manufacturing and establishes the company as the first known European customer for the Starfall vehicle.
Announced on September 15, 2026, the agreement will utilize Space Cargo Unlimited’s BentoBox payload platform to produce materials in Low Earth Orbit (LEO) before returning them to Earth. According to Reuters, the startup is currently in discussions with more than 100 potential customers, with approximately 40 percent originating from the life sciences and biotechnology sectors.
Scaling up microgravity production
The upcoming 2028 mission represents a tenfold increase in payload capacity for Space Cargo Unlimited. The company previously operated missions with a 100-kilogram limit. The Starfall contract expands that capacity to 1,000 kilograms, or one metric ton.
In a press release detailing the agreement, Space Cargo Unlimited Co-founder and CEO Nicolas Gaume highlighted the historical barriers to orbital production.
“For more than thirty years, we’ve known that manufacturing in microgravity can create materials and products that simply cannot be produced on Earth. The challenge has never been the science. The challenge has been making access commercially practical, repeatable and scalable.”
Demand for the expanded capacity appears robust. Reporting by Payload indicates that Space Cargo Unlimited has already sold one-third of its 1,000-kilogram allocation for the 2028 flight.
Starfall and the commercialization of Starship
The Space Cargo Unlimited contract is part of a broader commercial rollout for SpaceX’s Starfall reentry vehicle, which is designed to fly on the heavy-lift Starship launch system. SpaceX conducted the first demonstration mission of the Starfall capsule on a Falcon 9 rocket on June 23, 2026.
Other aerospace integrators are also securing space on future Starfall flights. In August 2026, Redwire subsidiary SpaceMD announced plans to fly 32 variants of its PIL-BOX payloads on a 2028 Starfall mission to research microgravity drug development. On September 21, 2026, German launch integrator Exolaunch confirmed an agreement for a Starfall mission scheduled for no earlier than 2029.
SpaceX is actively transitioning the Starship program from developmental testing to revenue-generating operations. Speaking to the vehicle’s long-term capabilities, SpaceX CEO Elon Musk noted the company’s aspirations are to deliver well over one million tons to orbit annually.
While Space Cargo Unlimited has publicized the 2028 target for its BentoBox mission, SpaceX has not officially confirmed the specific timetable for this flight.
AirPro News analysis
We view the transition from 100-kilogram research payloads to one-tonne commercial batches as a critical threshold for the in-space manufacturing sector. The high concentration of prospective biotechnology customers suggests that pharmaceuticals and advanced materials will likely drive the initial economic viability of orbital factories. If SpaceX can maintain the projected 2028 timeline for Starfall operations, the bottleneck for microgravity manufacturing will shift from launch availability to payload integration and terrestrial market demand.
