Satellite Environment

The satellite environment encompasses the physical and electromagnetic conditions encountered by satellites during launch and throughout their operational life in space. Most satellites operate within cislunar space, the region extending from the Earth’s surface to the orbit of the Moon. This environment imposes significant constraints on satellite design, manufacture, and operation.

Key characteristics of the satellite environment include high vacuum, extreme temperature variations, radiation from the Van Allen belts and solar activity, micrometeoroids and orbital debris, atomic oxygen at low Earth orbit altitudes, and the absence of convective heat transfer. These conditions can degrade materials, damage electronics, alter surface properties, and reduce system reliability, often increasing development cost and operational complexity.
