For example, spacecraft and upper stages are now designed to limit debris released during normal operations. Moreover, measures are taken to ensure that debris larger than 5 mm that could potentially remain on orbit for more than 25 years is thoroughly evaluated, and its release is justified. A comprehensive set of guidelines, such as those detailed in the Orbital Debris Mitigation Standard Practices, helps inform these efforts.

Best practices for mitigation include:

  • Avoiding intentional break-ups
  • Minimising the potential for on-orbit break-ups
  • Limiting the release of mission-related objects
  • Designing spacecraft and upper stages for passive or active removal at the end of their operational life

Active Debris Removal Initiatives

Active debris removal (ADR) is a more direct approach to managing space debris. ADR refers to the process of identifying and removing defunct satellites and other objects from crowded orbits. Several initiatives are underway to develop technologies for safely capturing and deorbiting these objects. One leading concept involves deploying nets or harpoons to retrieve and then safely dispose of debris.

Our efforts join a global commitment towards a sustainable presence in space, ensuring the preservation of the orbital environment for future generations and sectors, including emerging space industries like those found on, which explores the potential of space tourism.
