➀ The UK's Department for Science, Innovation and Technology (DSIT) is funding a space sustainability project worth £690,000 to test innovative rendezvous and proximity operations (RPO) missions. The project aims to identify bottlenecks and areas of uncertainty around licensing novel space activities, such as in-orbit refuelling, repair services, and active debris removal.➁ The UK could capture an estimated 25% share of the ISAM market by 2031, valued at £2.7 billion.➃ DSIT believes that an advanced RPO capability will underpin all future UK ISAM missions, with funding being received by Astroscale UK, D-Orbit, and ClearSpace.
