What Types of Satellites Constitute the “Pre-Starship Market” for Satellite Life Extension Services?

As the utilization of satellite technology continues to permeate various sectors, the need to efficiently manage this orbital infrastructure has never been more pressing. Satellite Lifecycle Extension Services (SLES) offer a pathway to extending the operational lives of satellites, thereby deferring the significant costs and resource investments associated with manufacturing and launching replacements. This article reviews SLES, detailing what these services entail, assessing which satellites stand to benefit considering factors such as purpose, mass, and orbit.

Orbital Shells: The Invisible Highways of the Space Economy

The advent of the space age has not only revolutionized our understanding of the cosmos but has also opened up new avenues for economic development. One of the key structures that have emerged in this new frontier is the concept of “orbital shells”—specific altitudinal bands around Earth where satellites and other man-made objects are placed in orbit. These shells serve as the backbone of the emerging space economy, supporting a wide range of services from telecommunications and Earth observation to scientific research and national security. This article reviews the types, applications, economic implications, and challenges associated with orbital shells.
