Amongst the many vital strategic and security priorities on the agenda at the NATO summit in Vilnius, it was refreshing to see important discussions about space security taking place. Space has long been an important domain for military operations and has been used actively by NATO for its own satellite communications (SATCOM) programme for almost two decades. However, it was not until 2019 that NATO Allies formally recognised space as an operational domain, opening the door to a greater focus on how space can play a pivotal role in our defence.
