The National Aeronautics and Space Administration (NASA) has selected Space Exploration Technologies Corp. (SpaceX) to provide launch services for the StarBurst mission, a small satellite designed to detect high-energy emissions from merging neutron stars. The Launch is targeted for no earlier than 2028 aboard a Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida.

In a press release issued on September 17, 2026, the agency confirmed the award was made as a firm-fixed-price task order under the Venture-Class Acquisition of Dedicated and Rideshare (VADR) contract. The StarBurst satellite will fly as part of a SpaceX Bandwagon rideshare mission, utilizing commercial launch capabilities to advance multimessenger astronomy.

Advancing multimessenger astronomy

The StarBurst mission represents a specialized effort to understand the origins of short gamma-ray bursts. The small satellite is engineered to detect the initial high-energy emissions generated when neutron stars merge. By capturing these early signals, researchers plan to combine StarBurst observations with gravitational-wave measurements and data collected by other ground and space-based telescopes.

This coordinated approach allows scientists to study cosmic events across multiple signal types. StarBurst is funded through the NASA Astrophysics Pioneers Program. The initiative is designed to support lower-cost space investigations by utilizing small spacecraft and alternative platforms to maximize scientific return on investment.

The VADR contract and commercial rideshare

The launch task order falls under the NASA VADR Contracts vehicle, which is managed by the Launch Services Program Office at the Kennedy Space Center. The VADR program provides flexible launch opportunities for science and technology payloads. The overarching VADR contract features a 10-year ordering period and a maximum total value of $1 billion across all awarded contracts.

Rather than requiring a dedicated launch vehicle, StarBurst will be integrated into a SpaceX Bandwagon rideshare mission. This approach allows NASA to leverage the established flight cadence of the Falcon 9 program to deploy smaller payloads cost-effectively.

We view the selection of a SpaceX Bandwagon mission for the StarBurst payload as a continued validation of the NASA Strategy to utilize commercial rideshare programs for specialized scientific research. By tapping into the VADR contract, the agency avoids the prohibitive costs of dedicated launch vehicles for small satellites. The Bandwagon program specifically caters to mid-inclination orbits, which are increasingly sought after for both commercial and scientific payloads. This award underscores the growing symbiosis between commercial launch cadence and government research objectives, allowing smaller astrophysics missions to reach orbit on timelines that would have been difficult to achieve a decade ago.

European launch provider Isar Aerospace and US-based rideshare integrator SEOPS have signed a Multiple Launch Service Agreement for five dedicated missions scheduled between 2028 and 2030. The contract expands SEOPS’ Waymaker rideshare program with European launch capabilities and brings Isar Aerospace’s 2028 manifest near full capacity.

Announced in a press release on September 15, 2026, the agreement builds on a previous single-launch contract secured in 2025, bringing the total number of joint missions between the two companies to six. The launches will utilize Isar Aerospace’s Spectrum launch vehicle, lifting off from the company’s dedicated pads at Andøya Space in Norway and Spaceport Nova Scotia in Canada.

Expanding the Waymaker rideshare program

SEOPS launched its Waymaker dedicated rideshare program in May 2026 to provide commercial and US government customers with access to Low Earth Orbit (LEO). The program aims to address a market analysis environment where demand for dedicated rideshare capacity is outpacing available supply. The agreement follows a rapid expansion phase for SEOPS, which announced in August 2026 that it had repurposed a previously acquired SpaceX Falcon 9 rocket for a 2028 LEO rideshare flight to provide additional opportunities for satellite operators.

SEOPS President Evan Hoyt noted the significance of adding a European provider to their portfolio to ensure resilient access to space.

“Isar has accomplished what very few companies ever do: build a new launch system and successfully reach orbit in what was only its second flight. Partnering for six missions with Isar Aerospace’s launch vehicle Spectrum reflects our confidence in their team and adds a powerful European capability to Waymaker.”

Hoyt added that future access to space requires real choice across vehicles, providers, and geographies, which the company is building through the Waymaker program alongside Isar Aerospace.

Momentum for the Spectrum launch vehicle

The new contracts follows Isar Aerospace’s successful second flight of the Spectrum rocket, designated “Mission Onward and Upward.” During that flight, the vehicle successfully deployed all payloads into orbit, making Isar Aerospace the first European Launcher Challenge startups to achieve orbital insertion.

Isar Aerospace Chief Commercial Officer Stella Guillen stated that the successful second flight directly strengthened market demand for the Spectrum vehicle.

“Signing a second contract with SEOPS is a strong vote of confidence in what we are building. We are proud to partner with SEOPS again and look forward to launching more missions together in the years ahead.”

We view this five-launch agreement as a clear indicator of the tightening capacity in the global commercial launch market, particularly for dedicated LEO rideshare missions. With major US providers heavily booked, integrators like SEOPS are actively diversifying their launch portfolios to ensure reliable access to space for their clients. By securing capacity on Isar Aerospace’s Spectrum vehicle, SEOPS mitigates the risk of domestic launch bottlenecks. For Isar Aerospace, filling its 2028 manifest this early validates its commercial strategy and demonstrates that successful orbital demonstration flights translate rapidly into firm multi-launch contracts.

Eutelsat Group has authorized Airbus Defence and Space to manufacture 229 additional OneWeb Low Earth Orbit (LEO) satellites, a €1 billion ($1.16 billion) investment designed to bridge the operational gap before the European Union’s IRIS² secure communications network comes online.

Announced on September 10, 2026, at the International Space Summit in Paris, the Authorisation to Proceed (ATP) brings Eutelsat’s total order of next-generation OneWeb satellites from Airbus to 669. The agreement ensures service continuity for the constellation by progressively replacing first-generation units reaching the end of their design life.

Manufacturing and Payload Upgrades

The new batch of satellites will be manufactured at the Airbus facility in Toulouse, France. According to Eutelsat, the spacecraft will feature advanced digital channelisers to enhance onboard processing capabilities and will include the capacity to embark hosted payloads. These technical upgrades are intended to maintain network performance until the full commercial availability of the IRIS² network.

The OneWeb architecture currently consists of over 600 first-generation satellites operating at an altitude of 1,200 kilometers across 12 synchronized orbital planes.

“This new contract from Eutelsat highlights the maturity of our product, the excellence of our supply chain and their trust in our industrial know-how for high rate satellite manufacturing for large-scale LEO constellations,” said Alain Fauré, Head of Space Systems at Airbus Defence and Space. “This is also a further step for European sovereignty, for which Airbus and Eutelsat have been key partners for decades!”

Launch Timeline and Fleet Replenishment

The September 10 agreement follows a series of procurement expansions. Eutelsat initially awarded Airbus a contract for 100 next-generation satellites in December 2024, expanding the order by 340 units in January 2026. The latest addition of 229 satellites will enable Eutelsat to progressively replenish and expand the OneWeb constellation through 2034.

Deliveries from the initial 440-satellite order are expected to begin in the fourth quarter of 2026. To support the constellation’s renewal, Eutelsat also announced on September 10, 2026, that it selected Arianespace to conduct two dedicated launches in 2027 and 2028 using the Ariane 64 rocket.

Eutelsat Chief Executive Officer Jean-François Fallacher described the order as a critical step for the company’s LEO strategy.

“With the first satellites from the 440 due for delivery and launch soon, our replenishment programme is moving forward,” Fallacher said. “The planned addition of 229 more satellites will further strengthen OneWeb, while IRIS² will bring significant new capacity and capabilities. Together, they give us a powerful roadmap to serve our customers, grow our LEO business and reinforce our role at the heart of Europe’s sovereign connectivity future.”

Bridging the Gap to IRIS²

The OneWeb replenishment strategy is closely tied to broader European space initiatives. On the same day as the satellite order, Airbus Defence and Space confirmed it signed an initial contract to design and build the first layer of satellites for Europe’s sovereign IRIS² constellation on behalf of Eutelsat. The 229 new OneWeb units will serve as a transitional capacity bridge until the European Union fully deploys the IRIS² system.

We view the concurrent announcements of the OneWeb expansion, the Arianespace launch contracts, and the IRIS² development as a consolidated push to secure European autonomy in low Earth orbit. By anchoring both the commercial OneWeb replenishment and the state-backed IRIS² program with Airbus, Eutelsat is streamlining its supply-chain while reinforcing the European aerospace industrial base. The selection of the Ariane 64 for upcoming launches further demonstrates a strategic pivot away from foreign launch providers, aligning commercial satellite operations with the European Union’s broader geopolitical objectives for sovereign connectivity.
