As launch costs continue to fall, thousands of satellites will be built over the next decade to deliver the next generation of space-based applications. NewSpace companies are planning large constellations to provide global, low-latency internet coverage, 5G comms, Earth-Observation analytics and satellite-based IoT for asset management. Manufacturers of military spacecraft are developing small satellites to deliver more affordable defence-related services, while universities and research institutes now routinely offer students the ability to design and launch CubeSats. Furthermore, developing countries are seeking low-cost access to space for national capacity building, the desire to become self-sufficient for data collection and to address local societal needs such as environmental monitoring, climate change, disaster management, deforestation, geospatial imaging to locate natural resources such as oil and gas, and understanding agriculture yields for food sustainability.
