Space is at the intersection of almost every investment buzz word for the 2020s; deep tech, AI/ML, IoT, robotics, miniaturisation, solar, data processing and management, in space (microgravity) manufacturing, 3D printing, blockchain, quantum computing...and those looking for disruption need to be familiar with developments in space tech. We compare it to the early days of renewables, when falling costs opened up the sector. The collapsing costs of launching rockets is doing the same now. NSF introduces and contextualises these extraordinary opportunities to promote informed decision making.
