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.
Mercury-Redstone 3, or Freedom 7, was the first United States human spaceflight, on May 5, 1961, piloted by astronaut Alan Shepard. It was the first crewed flight of Project Mercury. The project had the ultimate objective of putting an astronaut into orbit around the Earth and returning him safely. Shepard's mission was a 15-minute suborbital flight with the primary objective of demonstrating his ability to withstand the high g-forces of launch and atmospheric re-entry.
Blue Origin Enterprises, L.P. is an American space technology company headquartered in Kent, Washington. The company operates the suborbital New Shepard rocket and the heavy-lift New Glenn rocket. In addition to producing engines for its own rockets, Blue Origin supplies engines for other vehicles, including United Launch Alliance's Vulcan Centaur. It is also working on the Blue Moon human lunar lander for NASA's Artemis program, the Blue Ring spacecraft platform, and the Orbital Reef space station in partnership with other organizations.
A launch escape system (LES) or launch abort system (LAS) is a crew-safety system connected to a space capsule. It is used in the event of a critical emergency to quickly separate the capsule from its launch vehicle in case of an emergency requiring the abort of the launch, such as an impending explosion. The LES is typically controlled by a combination of automatic rocket failure detection, and a manual activation for the crew commander's use. The LES may be used while the launch vehicle is on the launch pad, or during its ascent. Such systems are usually of three types:
New Shepard is a fully reusable sub-orbital launch vehicle developed for space tourism by Blue Origin. The vehicle is named after Alan Shepard, who became the first American to travel into space and the fifth person to walk on the Moon. The vehicle is capable of vertical takeoff and landings. Additionally, it is also capable of carrying humans and customer payloads into a sub-orbital trajectory.
The Crew Dragon In-Flight Abort Test was a successful test of the SpaceX Dragon 2 abort system, conducted on 19 January 2020. It was the final assessment for the Crew Dragon capsule and Falcon 9 launch system before they would be certified to carry humans into space. Booster B1046.4 and an uncrewed capsule C205 were launched from Launch Complex 39A (LC-39A) on a suborbital trajectory, followed by an in-flight abort of the capsule at max Q and supersonic speed. The test was carried out successfully: the capsule pulled itself away from the booster after launch control commanded the abort, and landed safely.
Blue Origin NS-16 was a sub-orbital spaceflight mission operated by Blue Origin which flew on 20 July 2021. The mission was the sixteenth flight of the company's New Shepard integrated launch vehicle and spacecraft, and its first crewed flight. It carried into space American billionaire and Blue Origin founder Jeff Bezos, his brother Mark, pilot and Mercury 13 member Wally Funk, and Dutch student Oliver Daemen. The flight commenced from Blue Origin's Corn Ranch sub-orbital launch site in West Texas aboard the third flight of New Shepard booster NS4 and the spacecraft RSS First Step, both having previously flown on NS-14 and NS-15 earlier in the year.
Oliver Daemen is a Dutch space tourist who flew as part of the 20 July 2021, sub-orbital Blue Origin NS-16 spaceflight. At the time of his flight he was 18 years old, and became the youngest person, first teenager, and first person born in the 21st century to travel to space. He is a licensed pilot.
RSS First Step is a New Shepard space capsule, built and operated by American spaceflight company Blue Origin. It is the third New Shepard capsule to fly to space, and the first to fly passengers. Its first flight was the NS-14 mission, which reached an altitude of 107 km (66 mi) on 14 January 2021.
Blue Origin NS-19 was a crewed New Shepard sub-orbital spaceflight mission operated by Blue Origin that launched on 11 December 2021. The flight was scheduled to launch on 9 December 2021, later delayed to 11 December 2021.
Blue Origin NS-21 was a sub-orbital spaceflight mission, operated by Blue Origin, which launched on 4 June 2022 using the New Shepard rocket. It was Blue Origin's fifth crewed flight, and twenty-first overall to reach space.
Blue Origin NS-23 was an uncrewed sub-orbital spaceflight mission of Blue Origin's New Shepard rocket, which launched on September 12, 2022. The booster failed during max q about a minute after launch, triggering the launch escape system which removed the capsule from the booster. The capsule landed successfully, while the booster was destroyed upon impact with the ground.
Gary Lai is an American aerospace engineer. He was the chief architect for New Shepard, a vehicle developed by aerospace manufacturer Blue Origin for space tourism. On March 31, 2022, he flew on New Shepard's 20th mission to space, NS-20. He is a Co-Founder and the Chief Technology Officer of a company called Interlune.
Blue Origin NS-24 was an uncrewed sub-orbital spaceflight mission of Blue Origin's New Shepard rocket, which launched on December 19, 2023. It was New Shepard's first flight in over a year since the failure of Blue Origin NS-23, and was Blue Origin's 24th overall flight to go into space.
Blue Origin NS-17 was an uncrewed sub-orbital spaceflight mission of Blue Origin's New Shepard rocket, which launched on 26 August 2021. It was New Shepards 4th flight in 2021. It was also Blue Origin's 17th overall flight to go into space.
Blue Origin NS-15 was an uncrewed sub-orbital spaceflight mission of Blue Origin's New Shepard rocket, which launched on April 14, 2021. It was New Shepards 2nd flight in 2021 and Blue Origin's 15th overall flight to go into space.
Blue Origin NS-26 was a sub-orbital spaceflight mission, operated by Blue Origin, launched on August 29, 2024, using the New Shepard rocket.
Blue Origin NS-27 was an uncrewed sub-orbital spaceflight mission, operated by Blue Origin, launched on October 23, 2024 using the New Shepard rocket. Previously, an October 7 launch attempt was called off after rocket issues and a subsequent attempt on October 13 foiled by a GPS issue.
RSS Kármán Line is a New Shepard space capsule, built and operated by American spaceflight company Blue Origin. It is the fourth New Shepard capsule to fly to space, and is slated to be the second to fly passengers, after RSS First Step. The capsule's first uncrewed flight was the NS-27 mission on 23 October 2024, which was also the maiden flight of New Shepard booster NS5.
Blue Origin NS-28 was a sub-orbital spaceflight mission, operated by Blue Origin, which launched on November 22, 2024 using the New Shepard rocket.
