An essential part of ESA’s Space Safety programme is dedicated to getting and keeping Earth’s orbits clean from space debris. In the long run, the Agency aspires to stimulate a true circular economy in space, minimising the impact of spaceflight on Earth and its resources where possible. As part of ESA’s Zero Debris approach, new ESA missions will be designed for safe operations and disposal to stop the creation of new debris by 2030.
