Space warfare is combat that takes place in outer space, i.e.
outside the atmosphere. Technically, as a distinct classification,
it refers to battles where the targets themselves are in space. Space
warfare therefore includes ground-to-space warfare, such as attacking
satellites from the Earth, as well as space-to-space warfare, such as
satellites attacking satellites. In 2020 military satellites and, to a
lesser degree, commercial satellites that perform functions critical
to civilians, governments and militaries are now increasingly
capable of performing active and passive defence, offensive
interdiction and rendezvous operations, and covert and overt
attacks, while simultaneously carrying out their primary missions.
Space systems consist of three elements: a space element, a
terrestrial element, and a link element. The space element consists
of the platform in which astrodynamics is the primary principle
governing its movement through its environment. This book
provides deep insight into various dimensions of issues relating
to the subject.
