Space exploration is the use of astronomy and space technology to explore outer space. While the exploration of space is currently carried out mainly by astronomers with telescopes, its physical exploration is conducted both by uncrewed robotic space probes and human spaceflight. Space exploration, like its classical form astronomy, is one of the main sources for space science.
Space colonization is the process of establishing human settlements beyond Earth for prestige, commercial and strategic benefits. This is in contrast to space exploration for scientific benefits. Colonialism can involve exploitation of both resources and people by a distant entity.
Spaceflight is an application of astronautics to fly objects, usually spacecraft, into or through outer space, either with or without humans on board. Most spaceflight is uncrewed and conducted mainly with spacecraft such as satellites in orbit around Earth, but also includes space probes for flights beyond Earth orbit. Such spaceflights operate either by telerobotic or autonomous control. The first spaceflights began in the 1950s with the launches of the Soviet Sputnik satellites and American Explorer and Vanguard missions. Human spaceflight programs include the Soyuz, Shenzhou, the past Apollo Moon landing and the Space Shuttle programs. Other current spaceflight are conducted to the International Space Station and to China's Tiangong Space Station.
The National Space Society (NSS) is an American international nonprofit 501(c)(3) educational and scientific organization specializing in space advocacy. It is a member of the Independent Charities of America and an annual participant in the Combined Federal Campaign. The society's vision is: "People living and working in thriving communities beyond the Earth, and the use of the vast resources of space for the dramatic betterment of humanity."
The Space Age is a period encompassing the activities related to the space race, space exploration, space technology, and the cultural developments influenced by these events, beginning with the launch of Sputnik 1 on October 4, 1957, and continuing to the present.
The Vision for Space Exploration (VSE) was a plan for space exploration announced on January 14, 2004 by President George W. Bush. It was conceived as a response to the Space Shuttle Columbia disaster, the state of human spaceflight at NASA, and as a way to regain public enthusiasm for space exploration.
Private spaceflight refers to spaceflight activities undertaken by non-governmental entities, such as corporations, individuals, or non-profit organizations. This contrasts with public spaceflight, which is traditionally conducted by government agencies like NASA, ESA, or JAXA.
The Space Exploration Alliance (SEA) is an umbrella organization formed by 13 United States space advocacy groups, industry associations, and space policy organizations. It was established on June 3, 2004. The SEA's primary objective is to support the refocus of NASA's human space activities toward exploration beyond low Earth orbit (LEO).
This is a timeline of space exploration which includes notable achievements, first accomplishments and milestones in humanity's exploration of outer space.
Space advertising is the practice of advertising in space. This is usually done with product placements during crewed space missions.
The following outline is provided as an overview of and topical guide to space exploration.
The idea of sending humans to Mars has been the subject of aerospace engineering and scientific studies since the late 1940s as part of the broader exploration of Mars. Long-term proposals have included sending settlers and terraforming the planet. Currently, only robotic landers and rovers have been on Mars. The farthest humans have been beyond Earth is the Moon, under the U.S. National Aeronautics and Space Administration (NASA) Apollo program which ended in 1972.
The politics of outer space includes space treaties, law in space, international cooperation and conflict in space exploration, international economics, and the hypothetical political impact of any contact with extraterrestrial intelligence.
Space architecture is the theory and practice of designing and building inhabited environments in outer space. This mission statement for space architecture was developed in 2002 by participants in the 1st Space Architecture Symposium, organized at the World Space Congress in Houston, by the Aerospace Architecture Subcommittee, Design Engineering Technical Committee (DETC), American Institute of Aeronautics and Astronautics (AIAA).
Mars to Stay missions propose that astronauts sent to Mars for the first time should intend to remain there. Unused emergency return vehicles would be recycled into settlement construction as soon as the habitability of Mars becomes evident to the initial pioneers. Mars to Stay missions are advocated both to reduce cost and to ensure permanent settlement of Mars. Among many notable Mars to Stay advocates, former Apollo astronaut Buzz Aldrin has been particularly outspoken, suggesting in numerous forums "Forget the Moon, Let’s Head to Mars!" and, in June 2013, Aldrin promoted a crewed mission "to homestead Mars and become a two-planet species". In August 2015, Aldrin, in association with the Florida Institute of Technology, presented a "master plan", for NASA consideration, for astronauts, with a "tour of duty of ten years", to colonize Mars before the year 2040. The Mars Underground, Mars Homestead Project / Mars Foundation, Mars One, and Mars Artists Community advocacy groups and business organizations have also adopted Mars to Stay policy initiatives.
Human presence in space is the direct and mediated presence or telepresence of humans in outer space and in a broader sense also on any extraterrestrial astronomical body. Human presence in space, particularly through mediation, can take many physical forms from space debris, uncrewed spacecraft, artificial satellites, space observatories, crewed spacecraft, art in space, to human outposts in outer space such as space stations.
The space policy of the United States includes both the making of space policy through the legislative process, and the implementation of that policy in the United States' civilian and military space programs through regulatory agencies. The early history of United States space policy is linked to the US–Soviet Space Race of the 1960s, which gave way to the Space Shuttle program. At the moment, the US space policy is aimed at the exploration of the Moon and the subsequent colonization of Mars.
The Alliance for Space Development is a space advocacy organization dedicated to influencing space policy towards the goal of permanent human settlements in space. The founding executive members of the Alliance are the National Space Society and the Space Frontier Foundation. Member organizations of the Alliance are the Lifeboat Foundation, Mars Foundation, Mars Society, The Moon Society, Space Development Foundation, Space Development Steering Committee, Space For Humanity, Space Renaissance USA, Space Tourism Society, Students for the Exploration and Development of Space, Students on Capitol Hill, Tea Party in Space, and Waypaver Foundation. The primary goals of the Alliance are to elevate the growth of the space industry, reduce the cost of accessing space, and to clearly define space settlement as the reason for sending humans to space.
Lucianne Walkowicz is an American astronomer, artist, and activist. They were based at the Adler Planetarium until 2022 and are noted for their research contributions in stellar magnetic activity and its impact on planetary suitability for extraterrestrial life.
