The increase in space debris in Earth’s orbit is a problem that concerns the scientific community. Thousands of inactive satellites and rocket debris pose a threat to both Earth and future space missions.
A study by the University of British Columbia revealed that there is a 26% probability of this debris reentering the atmosphere, with inactive satellites being the main concern due to the risk of fragmentation and danger to the population.
International Collaboration for Space Sustainability
To address this issue, the European Space Agency (ESA) and the Spanish Space Agency (AEE) have signed a cooperation agreement in the Capture Payload Bay (CAT) mission.
This project will test a standardized docking interface, facilitating the removal of inactive satellites through safe and efficient captures.
Currently, the disposal of out-of-service satellites requires an operational spacecraft to capture them, a risky procedure due to the possibility of collisions and fragment generation.
With the implementation of standard interfaces, ESA aims to simplify the process, allowing for towing at the end of their operational life.
LUR-1: a Satellite with Pioneering Technology
In September 2024, the Spanish company AVS successfully launched the LUR-1 mission, which incorporates an innovative mechanical interface (MICE – Mechanical Interface for Capture at End-of-Life) for its safe capture at the end of its operability.
Additionally, LUR-1 integrates advanced navigation instruments designed to accurately measure:
- Distance and orientation during the proximity phase.
- Satellite rotation, facilitating its capture.
ESA points out that this MICE interface functions as a fastening point similar to towing hooks on vehicles, ensuring an efficient capture.
Spain and its Key Role in the Fight against Space Debris
The CAT interface, developed under the leadership of GMV in Spain, combines advanced robotics with relative navigation equipment, enabling high-precision docking operations.
This collaboration is a strategic springboard to achieve the ESA’s zero space debris goal, reinforcing safety and sustainability in orbit.
With this technology, the next step will be to demonstrate its effectiveness in real missions, contributing to a cleaner and more responsible future for space exploration.
