Ideas implemented through the Open Space Innovation Platform

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.
