Abstract

Currently valued at around $600 billion, the space economy is expected to reach $1.8 trillion by 2035, with vital terrestrial systems increasingly dependent on space infrastructure. Growth is largely driven by the rising deployment of small and medium satellites in low Earth orbit (LEO), yet most are single-use and quickly decommissioned after failure, contributing to orbital debris and challenging sustainability. This article examines opportunities and challenges in developing orbital servicing infrastructure for small satellites, highlighting how such technologies can extend operational lifetimes, reduce replacement costs and enhance the reliability of future constellations, supporting the long-term development of the LEO space economy.
