The European Space Agency (ESA) is Europe’s gateway to space. Its mission is to shape the development of Europe’s space capability and ensure that investment in space continues to deliver benefits to the citizens of Europe and the world.

ESA safeguards Europe’s guaranteed access to space through its Future Launchers Preparatory Programme, FLPP.
FLPP weighs up the opportunities and risks of different launch vehicle concepts and associated technologies. Its demonstrators and studies hone emerging technologies to give Europe's rocket builders a valuable head-start as they begin the demanding work of turning the chosen design into reality.
Based on a standardised scale of “Technology Readiness Levels” or TRL, technologies that have been demonstrated in a laboratory environment at Level 3, are further developed within FLPP and tested via integrated demonstrators to raise them to TRL 6.
Once a technology has reached level 6, much of the risk linked to using a new technology in a space environment has been mitigated. It can be quickly transferred to a development up to flight (TRL 9) with optimised cost and schedule.
FLPP activities
FLPP defines the concepts and requirements for new space transportation systems and services. Technologies are selected on their potential to reduce cost, improve performance, improve reliability, or on their ability to fulfil the specific needs of an identified system, demonstrator or mission.
Within the programme, integrated demonstrators are built by combining multiple technologies into one system or subsystem so that industry can use the technology with confidence.
