Space tourism

Space tourism is space travel for recreational, leisure or business purposes. A number of startup companies have sprung up in recent years, such as Virgin Galactic and XCOR Aerospace, hoping to create a sub-orbital space tourism industry. Orbital space tourism opportunities have been limited and expensive, with only the Russian Space Agency providing transport to date.

The publicized price for flights brokered by Space Adventures to the International Space Station aboard a Russian Soyuz spacecraft have been US $20–40 million, during the period 2001–2009 when 7 space tourists made 8 space flights. Some space tourists have signed contracts with third parties to conduct certain research activities while in orbit.

Commercialization of space

Commercialization of space is the use of equipment sent into or through outer space to provide goods or services of commercial value, either by a corporation or state. Examples of the commercial use of space include satellite navigation systems, satellite television and satellite radio. The first commercial use of outer space was in 1962, when the Telstar 1 satellite was launched to transmit television signals over the Atlantic ocean. By the 1980s individuals belonging to private firms were being launched into space to oversee commercial equipment deployment and operations. This eventually lead to opportunities for individuals to pay to be put into space in the early 2000s, which was the birth of space tourism. By 2004, global investment in all space sectors was estimated to be $50.8 billion.

In the decades following the advent of space tourism, many different concepts of the commercialization of space have evolved, from the founding of space tourism companies, such as Virgin Galactic, to ambitious projects such as Mars Colonization and Asteroid Mining.

Industri Antariksa Kita

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."

Space-related interdisciplinary fields

• Astrobiology
• Astrochemistry or cosmochemistry
• Planetary science – overlaps with Earth science
• Micro-g environment research
• Forensic astronomy
• Space archaeology – the study of human artifacts in outer space
• Archaeoastronomy – the history of human understanding of the universe

Space Science

Space science – study of everything in outer space. This has sometimes been called astronomy, but recently astronomy has come to be regarded as a division of broader space science, which has grown to include other related fields, such as studying issues related to space travel and space exploration (including space medicine), space archaeology and science performed in outer space (see space research).
