Space industry refers to economic activities related to
manufacturing components that go into Earth's orbit or beyond, delivering them to those regions, and related services. Owing to the prominence of the satellite-related activities, some sources use the term
satellite industry interchangeably with the term
space industry. The term
space business has also been used. A narrow definition encompasses only hardware providers (primarily related to launch vehicles and
satellites). This definition does not exclude certain activities, such as
space tourism. Thus more broadly, space industry can be described as the companies involved in the
space economy, and providing goods and services related to space. Space economy has been defined as "all public and private actors involved in developing and providing space-enabled products and services. It comprises a long
value-added chaining, starting with
research and development actors and manufacturers of
space hardware and ending with the providers of space-enabled products and services to final users."
