The Space Shuttle program was the fourth human spaceflight program carried out by the U.S. National Aeronautics and Space Administration (NASA), which accomplished routine transportation for Earth-to-orbit crew and cargo from 1981 to 2011. Its official name, Space Transportation System (STS), was taken from a 1969 plan for a system of reusable spacecraft of which it was the only item funded for development. It flew 135 missions and carried 355 astronauts from 16 countries, many on multiple trips.
The Altair spacecraft, previously known as the Lunar Surface Access Module or LSAM, was the planned lander spacecraft component of NASA's cancelled Constellation program. Astronauts would have used the spacecraft for landings on the Moon, which was intended to begin around 2019. The Altair spacecraft was planned to be used both for lunar sortie and lunar outpost missions.
The Crew Exploration Vehicle (CEV) was a component of the U.S. NASA Vision for Space Exploration plan. A competition was held to design a spacecraft that could carry humans to the destinations envisioned by the plan. The winning design was the Orion spacecraft.
A moonbase is a human outpost on or below the surface of the Moon. More than a mere site of activity or temporary camp, moonbases are extraterrestrial bases, supporting robotic or human activity, by providing surface infrastructure. As of 2024 missions to the Moon have realized single-mission bases,, as well as some small permanent installations.
The National Aeronautics and Space Administration is an independent agency of the U.S. federal government responsible for the civil space program, aeronautics research, and space research. Established in 1958, it succeeded the National Advisory Committee for Aeronautics (NACA) to give the U.S. space development effort a distinct civilian orientation, emphasizing peaceful applications in space science. It has since led most of America's space exploration programs, including Project Mercury, Project Gemini, the 1968–1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. Currently, NASA supports the International Space Station (ISS) along with the Commercial Crew Program, and oversees the development of the Orion spacecraft and the Space Launch System for the lunar Artemis program.
Orion is a partially reusable crewed spacecraft used in NASA's Artemis program. The spacecraft consists of a Crew Module (CM) space capsule designed by Lockheed Martin and the European Service Module (ESM) manufactured by Airbus Defence and Space. Capable of supporting a crew of four beyond low Earth orbit, Orion can last up to 21 days undocked and up to six months docked. It is equipped with solar panels, an automated docking system, and glass cockpit interfaces modeled after those used in the Boeing 787 Dreamliner. A single AJ10 engine provides the spacecraft's primary propulsion, while eight R-4D-11 engines, and six pods of custom reaction control system engines developed by Airbus, provide the spacecraft's secondary propulsion. Orion is intended to be launched atop a Space Launch System (SLS) rocket, with a tower launch escape system.
The European System Providing Refueling Infrastructure and Telecommunications (ESPRIT) is an under construction module of the Lunar Gateway. It will provide refueling through additional xenon and hydrazine capacity for use in the Power and Propulsion Element's ion engines and hydrazine thrusters. It will also provide additional communications equipment, a habitation area, and storage. It will have a launch mass of approximately 10,000 kg (22,000 lb), a length of 6.4 m (21 ft), and a diameter of 4.6 m (15 ft). ESA awarded two parallel design studies for ESPRIT, one mostly led by Airbus in partnership with Comex and OHB and one led by Thales Alenia Space. The construction of the module was approved in November 2019. On 14 October 2020, Thales Alenia Space announced that they had been selected by ESA to build the ESPRIT module.
The Mohammed bin Rashid Space Centre is a Dubai government organisation working on the UAE space programme, which includes various space satellite projects, such as the Emirates Mars Mission, the Emirates Lunar Mission, and the UAE astronaut programme. The centre actively works to promote space science and research in the region and encompasses the Emirates Institution for Advanced Science and Technology (EIAST).
The Deep Space Habitat (DSH) is a series of concepts explored between 2012 and 2018 by NASA for methods to support crewed exploration missions to the Moon, asteroids, and eventually Mars. Some of these concepts were eventually used in the Lunar Gateway program.
The European Service Module (ESM) is the service module component of the Orion spacecraft, serving as its primary power and propulsion component until it is discarded at the end of each mission. In January 2013, NASA announced that the European Space Agency (ESA) will contribute the service module for Artemis 1, based on the ESA's Automated Transfer Vehicle (ATV). It was delivered by Airbus Defence and Space in Bremen, in northern Germany to NASA at the end of 2018. After approval of the first module, the ESA will provide the ESMs from Artemis 2 to Artemis 6.
Artemis 2 is a scheduled mission of the NASA-led Artemis program. It will use the second launch of the Space Launch System (SLS) and include the first crewed mission of the Orion spacecraft. The mission is scheduled for no earlier than September 2025. Four astronauts will perform a flyby of the Moon and return to Earth, becoming the first crew to travel beyond low Earth orbit since Apollo 17 in 1972. Artemis 2 will be the first crewed launch from Launch Complex 39B of the Kennedy Space Center since STS-116 in 2006.
Artemis 3 is planned to be the first crewed Moon landing mission of the Artemis program and the first crewed flight of the Starship HLS lander. Artemis 3 is planned to be the second crewed Artemis mission and the first American crewed lunar landing since Apollo 17 in December 1972. In December 2023, the Government Accountability Office reported that the mission is not likely to occur before 2027; as of January 2024, NASA officially expects Artemis 3 to launch no earlier than September 2026 due to issues with the valves in Orion's life support system.
The Lunar Gateway, or simply Gateway, is a space station which Artemis program participants plan to assemble in an orbit near the Moon. The Gateway is intended to serve as a communication hub, science laboratory, and habitation module for astronauts. It is a multinational collaborative project: participants include NASA, the European Space Agency (ESA), the Japan Aerospace Exploration Agency (JAXA), the Canadian Space Agency (CSA) and the Mohammed Bin Rashid Space Centre (MBRSC). The Gateway is planned to be the first space station beyond low Earth orbit.
The Artemis program is a Moon exploration program that is led by the United States' National Aeronautics and Space Administration (NASA) and was formally established in 2017 via Space Policy Directive 1. The Artemis program is intended to reestablish a human presence on the Moon for the first time since the Apollo 17 moon mission in 1972. The program's stated long-term goal is to establish a permanent base on the Moon to facilitate human missions to Mars.
Artemis 4 is a planned mission of the NASA-led Artemis program. The mission will include the fourth use of a Space Launch System (SLS) launch vehicle, will send an Orion spacecraft with four astronauts to the Lunar Gateway space station, install a new module on the Gateway, and conduct the second lunar landing of the Artemis program.
Artemis 5 is the fifth planned mission of NASA's Artemis program and the first crewed flight of the Blue Moon lander. The mission will launch four astronauts on a Space Launch System rocket and an Orion to the Lunar Gateway and will be the third lunar landing of the Artemis program. In addition, Artemis V will also deliver two new elements to the Gateway Space Station.
