Low Earth Orbit

Low Earth orbit (LEO) will be covered to a greater extent in this book than other types of space systems for a multitude of reasons. The most important to me is that as space becomes more reachable and feasible for varying organizations to operate within, that accessibility will begin at LEO first. Since LEO will be the most readily available portion of the space domain to the widest potential operators, it will initially present the lion’s share of computing devices in space in need of appropriate cybersecurity implementations.
