One of the consequences of Brexit was that the UK was forced out of several key European Union science programs, including the Galileo satnav project and Horizon, the EU's flagship science research scheme. Now, the UK is set to rejoin Horizon as an associate country under what UK Prime Minister Rishi Sunak and European Commission President Ursula von der Leyen called a "bespoke deal."
The UK will also become an associate member of Copernicus, the EU's £8 billion (€9 billion) Earth observation satellite program. It won't be rejoining the Euratom nuclear research group, however, instead choosing to focus on its own nuclear fusion research. Under the terms of the deal, the UK will contribute almost €2.6 billion (£2.2 billion or $2.75 billion) per year on average for its participation in both Horizon and Copernicus.
