Summary
ESA has signed its first European Launcher Challenge contracts with Rocket Factory Augsburg, PLD Space and Isar Aerospace. The companies will receive support as milestones are met, while each launcher’s stated payload capacity remains a development target.
The European Space Agency (ESA) has signed the first contracts under its European Launcher Challenge, awarding development support to Rocket Factory Augsburg, PLD Space and Isar Aerospace. The contracts are intended to expand the supply of European launch services and strengthen Europe’s access to space. Funds can be secured as milestones are met, ESA says.
The awards follow an evaluation of the companies’ financial and technical proposals. ESA’s tender board considered factors including business case, engineering quality, resources, schedule and compliance. A contract with MaiaSpace is still being finalised; ESA says the award process is nearing completion and is expected to resume in the coming weeks.
Three launchers, three development paths
Germany’s Rocket Factory Augsburg is developing the three-stage RFA One, a rocket about 30 metres tall and 2.15 metres in diameter. It is planned to launch from SaxaVord in the UK and is designed to carry up to 500 kg to a 500 km sun-synchronous orbit. The contract is worth €186.9 million, funded mainly by Germany with a contribution from the UK.
A sun-synchronous orbit is arranged so that a satellite passes over a given area at roughly consistent local solar times, a useful property for repeat Earth observations. RFA’s stated capacity is a planned capability, not a report of an operational service.
Spain’s PLD Space is using its Miura 1 technology demonstrator, which flew from Spain in 2023, as a foundation for Miura 5 and related infrastructure. Miura 5 is planned to launch from Europe’s Spaceport in French Guiana and is designed to deliver payloads of up to 540 kg to a sun-synchronous orbit. PLD Space also plans upgraded capabilities for missions requiring greater payload capacity and orbital reach. Its €158.9 million contract is funded mainly by Spain, with a contribution from Germany.
Isar Aerospace, also based in Germany, is developing Spectrum, a two-stage launcher 28 metres tall and 2 metres in diameter. Its first flight lasted 30 seconds in 2025 from its dedicated pad at Andøya Spaceport in Norway. In its current configuration, Spectrum has ten engines and is targeting payloads of up to 1,000 kg to low Earth orbit. ESA says the company’s second vehicle is being prepared for a qualification flight carrying payloads intended for orbit. The €197.8 million contract is funded mainly by Germany, with contributions from Austria and Norway.
The challenge’s launch requirement
The challenge requires participating launch service providers to achieve an orbital launch before 2028. That milestone makes the programme about demonstrating a route to launch service, not just designing vehicles. ESA says the broader aim is to increase the range of services available to institutional and commercial customers and make European access to space more robust.
The contracts provide support while the launchers are being developed, but the companies still have to meet the challenge’s orbital-launch requirement. As ESA’s programme announcement notes, reaching orbit is not guaranteed; the stated payload figures describe the launchers’ intended capabilities.
