Helene Huby raises $450M to give Europe a ride home from orbit

Why it matters

Europe wants independent cargo access to orbit, and Huby now has $450M to pursue it. Nyx still must prove docking, recovery, and reuse against ESA's preferred 2028 demonstration timetable.

Helene Huby has announced a $450 million Series C for The Exploration Company, financing an accelerated attempt to build Europe's reusable route to orbit and back.

The September 8th round, first reported by TechCrunch, was co-led by Bessemer Venture Partners, Atomico, and the Scaleup Europe Fund, which is managed by EQT. Existing investors Balderton Capital, Plural, Cherry Ventures, and Red River West also participated. The valuation was not disclosed.

The Exploration Company says the round is the largest Series C announced by a European space business. That ranking has not been independently established. The confirmed figure is large enough on its own: the company's September 8th announcement puts its total funding at approximately $680 million, five years after Huby and a group of former Airbus and ArianeGroup engineers started building reusable spacecraft together.

Huby arrived in aerospace through a less conventional route than most rocket founders. She studied economics, applied mathematics, and public administration before joining Airbus in Germany in 2013. She went on to lead innovation work, serve as an ArianeGroup program director, and oversee space strategy and the European Service Module for NASA's Orion spacecraft.

Huby left Airbus in 2021 and founded The Exploration Company in July 2021 with a group of aerospace engineers, including Artur Koop, Jon Reijneveld, Pierre Vinet, and Sebastien Reichstadt.

That origin matters because the Series C is financing a plan considerably broader than one capsule. Huby is trying to assemble the spacecraft, propulsion, manufacturing, and launch infrastructure required for an independent European transportation chain. The near-term program is Nyx.

Nyx faces ESA's 2028 target

The near-term priority is Nyx, a reusable capsule designed to carry cargo to space stations and return it to Earth. Unlike a vehicle tied to one rocket, Nyx is designed to launch on multiple heavy launchers. The Exploration Company says it will eventually return up to 3,000 kilograms of cargo and be reused for as many as 10 missions, although both targets remain to be demonstrated in flight.

In 2024, the European Space Agency selected The Exploration Company and Thales Alenia Space to develop European cargo-return services. ESA awarded each company €25 million and called for an ISS demonstration ideally in 2028 and no later than 2030.

SpaceX's Dragon shows what Huby is trying to reproduce at European scale. Dragon completed NASA's 34th commercial resupply mission in June 2026, carrying research and hardware back from the ISS. Nyx remains a development program chasing an incumbent with years of operating data, established launch integration, and repeated cargo recovery.

The Exploration Company's own test history shows the distance still to cover. Mission Bikini reached orbit in July 2024, but an upper-stage anomaly prevented the rocket from releasing the demonstrator onto its planned reentry trajectory.

The larger Mission Possible capsule launched in 2025 and was lost after reentry. Aviation Week described the flight as a partial success. Recovery, refurbishment, autonomous docking, and repeated flight remain ahead.

The rocket comes after the capsule

The Series C also funds Storm, a reusable engine using liquid oxygen and biomethane in a full-flow staged-combustion cycle. The Exploration Company is developing Storm as the propulsion base for a future European heavy-lift rocket that it says could carry up to 40 tons to low-Earth orbit in a reusable configuration.

Storm expands Huby's bet from orbital logistics into launch. It also expands the capital requirement. According to the company's Series C announcement, the round will finance testing for Storm and development of Nyx.

The Exploration Company says it has booked 10 missions and secured over $2 billion in contracts and commitments from public and private customers, including ESA, Vast, and Starlab. The figure combines contracts with commitments, leaving the amount of firm, funded backlog unclear. Revenue, pricing, and profitability were not disclosed.

The Exploration Company now employs over 550 people across Europe, the United States, and the United Arab Emirates, according to its announcement. Its investors are financing a founder who left Europe's aerospace establishment to move faster, while relying on European agencies, public capital, and industrial policy to create a market for the result.

The $450 million buys Huby time, hardware, and hiring capacity. Nyx still has to dock, survive reentry, land, and fly again. Those tests will determine whether Europe's Dragon alternative becomes transportation infrastructure or remains a well-financed development program.
