Human spaceflight is spaceflight with a crew or passengers aboard a spacecraft, often with the spacecraft being operated directly by the onboard human crew. Spacecraft can also be remotely operated from ground stations on Earth, or autonomously, without any direct human involvement. People trained for spaceflight are called astronauts, cosmonauts (Russian), or taikonauts (Chinese); and non-professionals are referred to as spaceflight participants or spacefarers.
A spacecraft is a vehicle that is designed to fly in outer space. A type of artificial satellite, spacecraft are used for a variety of purposes, including communications, Earth observation, meteorology, navigation, space colonization, planetary exploration, and transportation of humans and cargo. All spacecraft except single-stage-to-orbit vehicles cannot get into space on their own, and require a launch vehicle.
Space tourism is human space travel for recreational purposes. There are several different types of space tourism, including orbital, suborbital and lunar space tourism.
Spaceflight is an application of astronautics to fly 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 spaceflight operate either by telerobotic or autonomous control. The more complex human spaceflight has been pursued soon after the first orbital satellites and has reached the Moon and permanent human presence in space around Earth, particularly with the use of space stations. 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.
Human spaceflight programs have been conducted, started, or planned by multiple countries and companies. The age of manned rocket flight was initiated by Fritz von Opel who piloted the world's first rocket-propelled flight on 30 September 1929. All space flights depend on rocket technology; von Opel was the co-designer and financier of the visionary project. Until the 21st century, human spaceflight programs were sponsored exclusively by governments, through either the military or civilian space agencies. With the launch of the privately funded SpaceShipOne in 2004, a new category of human spaceflight programs – commercial human spaceflight – arrived. By the end of 2022, three countries and one private company (SpaceX) had successfully launched humans to Earth orbit, and two private companies had launched humans on a suborbital trajectory. The criteria for what constitutes human spaceflight vary. The Fédération Aéronautique Internationale defines spaceflight as any flight over 100 kilometers (62 mi). In the United States professional, military, and commercial astronauts who travel above an altitude of 80 kilometers (50 mi) are awarded the United States Astronaut Badge. This article follows the FAI definition of spaceflight.
Scaled Composites is an American aerospace company founded by Burt Rutan and currently owned by Northrop Grumman. It is located at the Mojave Air and Space Port in Mojave, California, United States. Founded to develop experimental aircraft, the company now focuses on designing and developing concept craft and prototype fabrication processes for aircraft and other vehicles. It is known for unconventional designs, for its use of non-metal, composite materials, and for winning the Ansari X Prize with its experimental spacecraft SpaceShipOne.
The Ansari X Prize was a space competition in which the X Prize Foundation offered a US$10,000,000 prize for the first non-government organization to launch a reusable crewed spacecraft into space twice within two weeks. It was modeled after early 20th-century aviation prizes, and aimed to spur development of low-cost spaceflight.
Space Adventures, Inc. is an American space tourism company founded in 1998 by Eric C. Anderson. Its offerings include zero-gravity atmospheric flights, orbital spaceflights, and other spaceflight-related experiences including cosmonaut training, spacewalk training, and launch tours. Plans announced thus far include sub-orbital and lunar spaceflights, though these are not being actively pursued at present. Nine of its clients have participated in the orbital spaceflight program with Space Adventures, including one who took two separate trips to space.
SpaceShipOne is an experimental air-launched rocket-powered aircraft with sub-orbital spaceflight capability at speeds of up to 3,000 ft/s (2,000 mph) / 910 m/s (3,300 km/h) using a hybrid rocket motor. The design features a unique "feathering" atmospheric reentry system where the rear half of the wing and the twin tail booms folds 70 degrees upward along a hinge running the length of the wing; this increases drag while retaining stability. SpaceShipOne completed the first crewed private spaceflight in 2004. That same year, it won the US$10 million Ansari X Prize and was immediately retired from active service. Its mother ship was named "White Knight". Both craft were developed and flown by Mojave Aerospace Ventures, which was a joint venture between Paul Allen and Scaled Composites, Burt Rutan's aviation company. Allen provided the funding of approximately US$25 million.
The Canadian Arrow was a privately funded, early-2000s rocket and space tourism project concept founded by London, Ontario, Canada entrepreneurs Geoff Sheerin, Dan McKibbon and Chris Corke. The project's objective was to take the first civilians into space, on a vertical sub-orbital spaceflight reaching an altitude of 112 km.
A sub-orbital spaceflight is a spaceflight in which the spacecraft reaches outer space, but its trajectory intersects the surface of the gravitating body from which it was launched. Hence, it will not complete one orbital revolution, will not become an artificial satellite nor will it reach escape velocity.
Flight 15P of SpaceShipOne (X0) was the first privately funded human spaceflight. It took place on June 21, 2004. It was the fourth powered test flight of the Tier One program, with the previous three test flights reaching much lower altitudes. The flight carried only its pilot, Mike Melvill, who thus became the first non-governmental astronaut.
Tier One was a Scaled Composites' 1990s–2004 program of suborbital human spaceflight using the reusable spacecraft SpaceShipOne and its launcher White Knight. The craft was designed by Burt Rutan, and the project was funded 20 million US Dollars by Paul Allen. In 2004 it made the first privately funded human spaceflight and won the 10 million US Dollars Ansari X Prize for the first non-governmental reusable crewed spacecraft.
Private spaceflight is spaceflight or the development of spaceflight technology that is conducted and paid for by an entity other than a government agency.
Flight 16P of SpaceShipOne was a spaceflight in the Tier One program that took place on September 29, 2004. It was the first competitive flight in the Ansari X PRIZE competition to demonstrate a non-governmental reusable crewed spacecraft, and is hence also referred to as the X1 flight. A serious roll excursion occurred during boost, so the flight did not achieve the expected altitude. However, it exceeded 100 km altitude, making it a successful X PRIZE flight.
Flight 17P of SpaceShipOne was a spaceflight in the Tier One program that took place on October 4, 2004. It was the second competitive flight in the Ansari X Prize competition to demonstrate a non-governmental reusable crewed spacecraft, and is hence also referred to as the X2 flight. It was a successful flight, winning the X PRIZE.
The X Prize Cup is a two-day air and space exposition which was the result of a partnership between the X Prize Foundation and the State of New Mexico that began in 2004 when the Ansari X-Prize was held. This led to plans to build the world's first true rocket festival. Three X-Prize Cups have been held: in 2005, 2006 and 2007. Each X Prize Cup hosts different events and demonstrations, such as rocket-powered bicycles, rocket jet packs; but particularly notable are the Lunar Lander Challenge and the Space Elevator Games. 85,000 visitors attended the 2007 X Prize Cup. Although there was no X Prize Cup in 2009, there was a Lunar Lander Challenge.
A space competition is an inducement prize contest offering a prize to be given to the first competitor who demonstrates a space vehicle, or a space exploration apparatus, which meets a set of pre-established criteria. It spurs pioneering development in private spaceflight.
The following is a timeline of important events in the history of private spaceflight, including important technical as well as legislative and political advances. Though the industry has its origins in the early 1960s, soon after the beginning of the Space Age, private companies did not begin conducting launches into space until the 1980s, and it was not until the 21st century that multiple companies began privately developing and operating launch vehicles and spacecraft in earnest.
