Where is the space sector headed? How can public and private actors work together to solve mutual challenges and sustain growth? What is the role of government programmes and funding? This paper addresses these and other questions by reviewing the evolving relationship between public and private actors in the space sector over the last two decades, based on case studies from North America, Europe and Asia. It provides new evidence for navigating the post-Covid-19 era, notably by exploring the range of government roles in supporting space sector innovation and expansion, from funder and developer of space programmes to partner and enabler of private sector growth.
