Europe continues to build its in-space technology legacy, with Hera’s software experiments extending a line of demonstrations from OPS-SAT, Proba missions, and Henon CubeSats to test new technologies in space.

Supporters say the program aims to mature autonomous spacecraft capabilities, reduce dependence on ground control, and boost mission resilience for future exploration.

Jorge Lopez Trescastro explains the onboard computer runs a LEON3 processor inside a protected sandbox, allowing guest software to run for a few hours per session with automatic shutdown if problems arise.

The OSIP ideas call invites initial outlines by mid-October 2026, with selected teams moving on to full implementation submissions by May 31, 2027, for testing in August 2027 over a one-month period.

Experiments will test advanced onboard intelligence, image processing, and AI-based autonomy directly on the spacecraft while safeguarding flight-critical systems.

After completing its primary planetary defence objectives around Didymos and Dimorphos, Hera will host onboard software experiments in a safeguarded sandbox environment.

ESA invites European researchers and companies to run software in deep space aboard Hera, effectively turning the mission into a flying software laboratory starting mid-2027, millions of kilometers from Earth.

The program seeks to accelerate European innovation, reinforce leadership in advanced space systems, and explore how onboard decision-making can enhance autonomy and resilience.
