===Commercialization of space===
{{Main|Commercialization of space}}
The commercialization of space first started out with the launching of private satellites by NASA or other space agencies. Current examples of the commercial satellite use of space include [[satellite navigation system]]s, satellite television, satellite communications (such as internet services) and [[satellite radio]]. The next step of commercialization of space was seen as human spaceflight. Flying humans safely to and from space had become routine to NASA and Russia.<ref>Gregory, Frederick; Garber, S. J. ''Looking Backward, Looking Forward: Forty Years of U.S. Human Spaceflight, 2002,'' pp. 73–80. Making Human Spaceflight as Safe as Possible.</ref> Reusable spacecraft were an entirely new engineering challenge, something only seen in novels and films like Star Trek and War of the Worlds. Astronaut [[Buzz Aldrin]] supported the use of making a reusable vehicle like the space shuttle. Aldrin held that reusable spacecraft were the key in making space travel affordable, stating that the use of "passenger space travel is a huge potential market big enough to justify the creation of reusable launch vehicles".<ref>Aldrin, Buzz; Garber, S.

Apollo and Beyond.</ref> [[Space tourism]] is a next step in the use of reusable vehicles in the commercialization of space. The purpose of this form of [[Human spaceflight|space travel]] is personal pleasure.

[[Private spaceflight|Private spaceflight companies]] such as [[SpaceX]] and [[Blue Origin]], and [[Orbital Technologies Commercial Space Station|commercial space stations]] such as the Axiom Space and the [[Bigelow Commercial Space Station]] have changed the cost and overall landscape of space exploration, and are expected to continue to do so in the near future.
