About us
The Discovery & Preparation elements of ESA's Discovery, Preparation and Technology Development (DPTD) activities carry out preparatory analysis and lay the groundwork for the Agency’s short- to medium-term future activities.
ESA's Discovery & Preparation (D&P) activities lay the groundwork for ESA's future space missions and strategic decisions. Through early-stage feasibility studies, blue sky research and open innovation campaigns run via the Open Space Innovation Platform, D&P explores pioneering concepts to provide ESA and its Member States with the vital insights needed to approve, shape and fund the next generation of space programmes.

OSIP Highlights July-December 2025
From self-healing spacecraft materials to thrusters that harvest the atmosphere as propellant, the ideas emerging from the Discovery Channel on ESA's Open Space Innovation Platform (OSIP) represent some of the most ambitious and unconventional thinking in European space research. Among the 72 activities funded by ESA's Discovery & Preparation programme through OSIP between July and December 2025, here are six that showcase the Programme's commitment to blue-sky research and transformative innovation.
