🚀 ESA Charts Bold Path for Europe’s Space Future

From in-orbit demonstrations to space-based solar power, new initiatives aim to strengthen Europe’s autonomy and innovation in space

In-Orbit Demonstration

To accelerate innovation, ESA’s Directorate is expanding in-orbit demonstration missions through the ‘Fly’ element of GSTP. These small satellites and CubeSats give European companies the chance to gain early flight heritage for new technologies—because the most reliable way to prove a system works in space is to fly it.

Upcoming missions include:

PRETTY – demonstrating satellite navigation reflectometry, using reflected signals to collect environmental data.

GomX-5 – testing high-speed communication links.

M-Argo – venturing into deep space to explore an asteroid.

Precision Formation Flying

ESA is also advancing the GSTP Precision Formation Flying Component, supporting the final production and use of the Proba-3 mission. This double-satellite mission will fly with millimetre-scale precision to create an artificial solar eclipse.

Proba-3 will showcase the potential of formation flying, paving the way for future multi-satellite missions operating as a single virtual structure to maximize scientific return.

EEE Space Component Sovereignty

Electrical, Electronic and Electromechanical (EEE) components are the backbone of spacecraft. Yet many high-value parts used in ESA missions are sourced outside Europe, leaving the industry vulnerable to supply shocks and export restrictions.

To address this, ESA proposes the EEE Space Component Sovereignty for Europe initiative, ensuring a stable and predictable supply chain over the next five years. This effort, in collaboration with Member States, industry, and European institutions, will strengthen Europe’s competitiveness and resilience in the global space market.

SOLARIS: Space-Based Solar Power

ESA is investigating the concept of Space-Based Solar Power (SBSP) through the SOLARIS programme. Since the Sun shines continuously in space, SBSP could provide a powerful tool for Europe’s energy transition by beaming clean energy down to Earth.

Key technologies under study include:

Advanced photovoltaic systems

Wireless power transmission

In-orbit manufacturing

Even if SBSP is not adopted operationally, these technologies will deliver valuable benefits across multiple sectors.

ENDURE: Radioisotope Energy for Exploration

ESA is launching ENDURE (EuropeaN Devices Using Radioisotope Energy), a GSTP component to establish a fully European capability for radioisotope heat and power systems by the end of the decade.

Based on reprocessed nuclear waste, ENDURE will cover fuel production, encapsulation, and system development. This will end Europe’s reliance on external suppliers for critical energy systems needed in extreme environments—from the long lunar nights to the harsh conditions of Mars and the outer Solar System.

Setting the Course at CM22

On 22–23 November 2022, ESA Director General Josef Aschbacher presented these proposals at the Council at Ministerial Level (CM22). Together, they set the strategic direction for Europe’s future in space—ensuring innovation, autonomy, and sustainability for decades to come.
