Artemis 4
Artemis 4 (officially Artemis IV) is the fourth planned mission of NASA's Artemis program. The mission will launch four astronauts on a Space Launch System rocket and an Orion to the Lunar Gateway and the second lunar landing of the Artemis program. Overview The main objective of the mission will be assembly of the Lunar Gateway. The mission will deliver the I-Hab habitat module, developed by the European Space Agency and the Japanese space agency JAXA, to the Gateway. The module will be docked with the first Gateway elements, the Power and Propulsion Element and Habitation and Logistics Outpost. The astronauts will then board a Starship HLS docked to the station and descend to the lunar surface for a multi-day mission. Artemis IV will also be the first flight of the Block 1B version of the Space Launch System, which will replace the Interim Cryogenic Propulsion Stage used on the first three Artemis missions with the more powerful Exploration Upper Stage. This upgrade in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NASA
The National Aeronautics and Space Administration (NASA ) is an independent agency of the US federal government responsible for the civil space program, aeronautics research, and space research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station. The agency is also responsible for the Launch Services Program, which provides oversight of launch operations and countdown management f ...

Power And Propulsion Element
The Power and Propulsion Element (PPE), previously known as the Asteroid Redirect Vehicle propulsion system, is a planned solar electric ion propulsion module being developed by Maxar Technologies for NASA. It is one of the major components of the Gateway. The PPE will allow access to the entire lunar surface and a wide range of lunar orbits and double as a space tug for visiting craft. The PPE originally started development at the Jet Propulsion Laboratory as a part of the now cancelled Asteroid Redirect Mission, but is now led and managed by the NASA John H. Glenn Research Center, in Cleveland, Ohio. When ARM was cancelled, the solar electric propulsion was repurposed as the PPE for the Gateway. The PPE is designed to be able to transfer the reusable Gateway to lunar orbit. It will also serve as the communications center of the Gateway. The PPE is intended to have a mass of 8–9 tons and the capability to generate 50 kW of solar electric power using Roll Out Sola ...

Near-rectilinear Halo Orbit
A near-rectilinear halo orbit (NRHO) is a halo orbit with slightly curved – or nearly straight – sides between close passes with an orbiting body. The 2022 CAPSTONE mission is the first such orbit in cislunar space, and this Moon-centric orbit will serve as a staging area for future lunar missions. The orbit could be used with other bodies in the Solar System and beyond. A halo orbit is a periodic, three-dimensional orbit associated with one of the L1, L2 and L3 Lagrange points. Near-rectilinear means that some segments of the orbit have a greater curvature than those of an elliptical orbit of the same maximum diameter, and other segments have a curvature less than that of an elliptical orbit of the same maximum diameter (taking maximum diameter as that of the smallest circle that contains the whole of the orbit). In the extreme case all segments have zero curvature with four points with infinite curvature (''i.e.'' a polygon). Such a non-elliptical orbit would require at lea ...

Crewed Spacecraft
This is a list of all crewed spacecraft types that have flown into space, including sub-orbital flights above 80 km, Space Stations that have been visited by at least one crew, and spacecraft currently planned to operate with crew in the future. It does not contain spacecraft that have only flown un-crewed and have retired from service, even if they were designed for crewed flight, such as Buran, or crewed flights by spacecraft below 80 km. There is some debate concerning the height at which space is reached (the Karman Line), the Fédération Aéronautique Internationale (FAI) recognise 100 km, NASA, and the USAF recognise this as 50 miles (approx 80 km) - this article choses the latter, to include the widest possible definition. Since the first crewed spaceflight of Vostok 1 in 1961 there have been 13 types of spacecraft that have made crewed flights into space - nine American, three Russian, and one Chinese. There are currently five operational crewed s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Artemis Missions
The Artemis program is a human spaceflight program by the United States. Missions in the program are aimed at exploration of the Moon, including crewed and robotic exploration of the lunar surface.

Super Heavy-lift Launch Vehicle
A super heavy-lift launch vehicle can lift to low Earth orbit more than by United States (NASA) classification or by Russian classification. It is the most capable launch vehicle classification by mass to orbit, exceeding that of the heavy-lift launch vehicle classification. Crewed lunar and interplanetary missions are often developed around these launch vehicles' payload capacity. Many early super heavy-lift launch vehicle concepts were made in the 1960s, such as the Sea Dragon. During the Space Race, the Saturn V and N1 were built by the United States and Soviet Union. After the Saturn V's successful Apollo program and the N1's failures, the Soviets' Energia launched twice in the 1980s, once with the Buran spaceplane. The next two decades saw multiple concepts drawn out once again, most notably Shuttle-derived vehicles and Rus-M, but none would be built. In the 2010s, super heavy-lift launch vehicles received interest once again, leading to the launch of the Falcon Heav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
