While we accept that the scope of the UK space industry is quickly changing and that the Government must take an adaptable approach to measuring its success, dropping headline targets when producing strategies and plans indicates a lack of ambition. If the implementation of the new National Space Strategy is to be assessed effectively, we must be able to observe if positive changes have been achieved in the space sector against some indication of what success looks like. The Government and UK Space Agency should publish the metrics by which the progress of the UK’s space sector will be measured (including a justification for why these metrics have been chosen) and set a clear target against which the success of the sector can be judged. These should be published alongside the implementation plan.
