What Is Driver Of The Space Power Systems Market?

An increasing number of satellite launches is expected to propel the growth of the space power systems market going forward. Satellite launches refer to the deployment of satellites into orbit using launch vehicles to support applications such as communication, Earth observation, navigation, and scientific research. The surge in satellite launches is primarily driven by the need to expand high-speed internet access worldwide through mega-constellations such as Starlink and OneWeb. Space power systems support satellite launches by providing reliable energy sources that enable satellite operations, propulsion, and communication once deployed in orbit. For instance, in April 2024, according to the Indian Space Research Organisation (ISRO), an India-based space agency, in 2023, a total of 3,143 space objects were added to the orbital environment from 212 launches and on-orbit break-up events, marking a significant increase from the 2,533 objects resulting from 179 launches in 2022. Therefore, the increasing number of satellite launches is driving the growth of the space power systems industry.
