Key Message
Early coordination between technology developers, end-users, and ESA is helping mature sustainable space transportation solutions with strong commercial potential. Two new ESA Invitation to Tenders have opened, offering funding for system studies or funding and technical support for selected teams to develop their technologies over 12 months.
The theme of environmental sustainability took centre stage at the European Space Agency’s FIRST! Sustainability pitch day, where the European space technology community converged on a shared goal: demonstrating that environmental sustainability, business opportunities and performance improvements in space transportation can go hand in hand.
ESA is now inviting proposals for system studies and technology maturation through a new Invitation to Tender (ITT) under the FIRST! Sustainability initiative. Teams with promising technology concepts will receive a 12-month contract to develop their technologies with ESA support, targeting Technology Readiness Level (TRL) 4.
“This initiative ties technical development directly to Europe’s long-term ambitions in space,” said Valère Girardin, FLPP Project Manager at ESA. “We are targeting the kind of capabilities that will make sustainable space transportation both viable and competitive.”
The initiative supports ESA’s long-term strategic vision by aligning technological development with environmental responsibility: a core priority under ESA Strategy 2040 and the ESA Green Agenda.
The structured, cross-sector engagement seen at the pitch day is uncommon in the industry, but it is an everyday feature of FLPP, ESA’s programme for future space transportation. While innovation in the sector has often been fragmented or isolated, FLPP provides a coordinated, pan-European model that focuses on the entire space transportation development chain. It brings together industry, research institutions, investors, national institutions, and end-users from the early phases of technology development. FIRST! sits within this framework, focusing specifically on the maturation of disruptive technologies currently at early development stages.
The pitch day reviewed 78 ideas from 13 countries. It created a shared forum for space transportation providers, developers, ESA experts, and stakeholders to test proposals against practical needs.
The value of early coordination was evident throughout the day, with developers gaining insight into market logic and end-users seeing emerging solutions. Gaps were clarified and ideas sharpened. The process illustrated how FLPP uses structured dialogue to ensure that new technologies are not only relevant, but scalable. ESA also facilitated one-to-one B2B sessions for 14 participating entities, enabling direct conversations on feasibility and potential collaboration.
Many of the conversations also challenged assumptions about sustainability. “If you can integrate [sustainability] into your model and business case, then it becomes a competitive advantage,” said Stefan Zeller from The Exploration Company. “Reusability reduces cost, so we can use it as a business model while supporting the environment.”
Environmental Performance Engineer Antoinette Ott of MaiaSpace agreed and noted that shared values can influence client decisions. “Sustainability is one of the core values of a European citizen, so making space transportation more sustainable attracts more European clients,” she said. “That duality should be in sync instead of viewed as a trade-off.”
The FIRST! Sustainability ITT is now open to organisations in participating member states. Each selected project team will receive, in addition to study funding:
- access to ESA expertise
- technical guidance
- testing support
For developers working on early-stage, high-potential concepts, this represents a direct opportunity to advance their technologies within a coordinated, European framework.
The FIRST! Sustainability ITTs are now open.
