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.
Space tourism is human space travel for recreational purposes. There are several different types of space tourism, including orbital, suborbital and lunar space tourism. Tourists are motivated by the possibility of viewing Earth from space, feeling weightlessness, experiencing extremely high speed and something unusual, and contributing to science.
Human spaceflight programs have been conducted, started, or planned by multiple countries and companies. 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.
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.
A spaceplane is a vehicle that can fly and glide like an aircraft in Earth's atmosphere and maneuver like a spacecraft in outer space. To do so, spaceplanes must incorporate features of both aircraft and spacecraft. Orbital spaceplanes tend to be more similar to conventional spacecraft, while sub-orbital spaceplanes tend to be more similar to fixed-wing aircraft. All spaceplanes to date have been rocket-powered for takeoff and climb, but have then landed as unpowered gliders.
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.
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 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.
Virgin Galactic Holdings, Inc. is a British-American spaceflight company founded by Richard Branson and the Virgin Group conglomerate which retains an 11.9% stake through Virgin Investments Limited. It is headquartered in California, and operates from New Mexico. The company develops commercial spacecraft and provides suborbital spaceflights to space tourists. Virgin Galactic's suborbital spacecraft are air launched from beneath a carrier airplane known as White Knight Two. Virgin Galactic's maiden spaceflight occurred in 2018 with its VSS Unity spaceship. Branson had originally hoped to see a maiden spaceflight by 2010, but the date was delayed, primarily due to the October 2014 crash of VSS Enterprise.
Rocketplane Limited, Inc. was a spacecraft design and development company headquartered in De Pere, Wisconsin. After filing for bankruptcy, the company reincorporated as Rocketplane Global Inc.
The Rocketplane XP was a suborbital spaceplane design that was under development c. 2005 by Rocketplane Kistler. The vehicle was to be powered by two jet engines and a rocket engine, intended to enable it to reach suborbital space. The XP would have operated from existing spaceports in a manner consistent with established commercial aviation practices. Commercial flights were projected to begin in 2009. Rocketplane Global declared bankruptcy in mid-June 2010. Their assets were auctioned off in 2011.
SpaceShip III was an upcoming class of spaceplanes by Virgin Galactic to follow SpaceShipTwo. It was first teased on the Virgin Galactic Twitter account on 25 February 2021 announcing the rollout of the first SpaceShip III plane on 30 March 2021.
XCOR Aerospace was an American private spaceflight and rocket engine development company based at the Mojave Air and Space Port in Mojave, California, Midland International Air and Spaceport in Midland, Texas and the Amsterdam area, the Netherlands. XCOR was formed in 1999 by former members of the Rotary Rocket rocket engine development team, and ceased operations in 2017.
The Airbus Defence and Space Spaceplane, also called EADS Astrium TBN according to some sources, is a suborbital spaceplane concept for carrying space tourists, proposed by EADS Astrium, the space subsidiary of the European consortium EADS. A full-size mockup was officially unveiled in Paris, France, on June 13, 2007, and is now on display in the Concorde hall of the Musée de l'Air et de l'Espace. The project is the first space tourism entry by a major aerospace contractor.
The XCOR Lynx was a proposed suborbital horizontal-takeoff, horizontal-landing (HTHL), rocket-powered spaceplane that was under development by the California-based company XCOR Aerospace to compete in the emerging suborbital spaceflight market. The Lynx was intended to carry one pilot, a ticketed passenger, and/or a payload above 100 kilometres (62 mi) altitude. The concept was under development since 2003, when a two-person suborbital spaceplane was announced under the name Xerus.
Air-launch-to-orbit (ALTO) is the method of launching smaller rockets at altitude from a heavier conventional horizontal-takeoff aircraft, to carry satellites to low Earth orbit. It is a follow-on development of air launches of experimental aircraft that began in the late 1940s. This method, when employed for orbital payload insertion, presents significant advantages over conventional vertical rocket launches, particularly because of the reduced mass, thrust, cost of the rocket, geographical factors, and natural disasters.
Aircraft have different ways to take off and land. Conventional airplanes accelerate along the ground until reaching a speed that is sufficient for the airplane to takeoff and climb at a safe speed. Some airplanes can take off at low speed, this being a short takeoff. Some aircraft such as helicopters and Harrier jump jets can take off and land vertically. Rockets also usually take off vertically, but some designs can land horizontally.
Exos Aerospace Systems & Technologies is an aerospace manufacturer and developer of reusable launch systems intended to support uncrewed orbital spaceflight launches, and is based in Caddo Mills, Texas.
VR-190 was the USSR's first rocket project designed to launch a human into suborbital space flight on a ballistic trajectory. The project ran in the 1940s and 1950s and, according to official sources, did not achieve its set goals. However, conspiracy theories surrounding the project claim that although crewed flights officially failed, cosmonauts were successfully sent into space in the 1950s.
