Artemis III
Artemis 3 (officially Artemis III) is planned as the first crewed Moon landing mission of the Artemis program and the first crewed flight of the Starship HLS lander. Scheduled for launch in 2025, Artemis 3 is planned to be the second crewed Artemis mission and the first crewed lunar landing since Apollo 17 in 1972. Artemis 3 is planned to place the first woman and non-white person on the Moon. Overview The Artemis III plan is to land a crew at the Moon's south polar region. It is planned to have two astronauts on the surface of the Moon for about one week. The mission is intended to be the first to place a woman and a non-white person on the Moon. While up to four astronauts would leave Earth on board Orion MPCV, the surface mission with the Human Landing System (HLS) will consist of two crew members, who will remain on the surface for 6.5 days. The remaining astronauts will stay on board Orion. The two astronauts will conduct up to four spacewalks on the Moon's surface, pe ...

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 ...

Apollo 17
Apollo 17 (December 7–19, 1972) was the final mission of NASA's Apollo program, the most recent time humans have set foot on the Moon or traveled beyond low Earth orbit. Commander Gene Cernan and Lunar Module Pilot Harrison Schmitt walked on the Moon, while Command Module Pilot Ronald Evans (astronaut), Ronald Evans orbited above. Schmitt was the only professional geologist to land on the Moon; he was selected in place of Joe Engle, as NASA had been under pressure to send a scientist to the Moon. The mission's heavy emphasis on science meant the inclusion of a number of new experiments, including a Fe, Fi, Fo, Fum, and Phooey, biological experiment containing five mice that was carried in the command module. Mission planners had two primary goals in deciding on the landing site: to sample Lunar highlands, lunar highland material older than that at Mare Imbrium and to investigate the possibility of relatively recent Volcano, volcanic activity. They therefore selected Taurus– ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Artemis III CONOPS
In ancient Greek mythology and religion, Artemis (; grc-gre, Ἄρτεμις) is the goddess of the hunt, the wilderness, wild animals, nature, vegetation, childbirth, care of children, and chastity. She was heavily identified with Selene, the Moon, and Hecate, another Moon goddess, and was thus regarded as one of the most prominent lunar deities in mythology, alongside the aforementioned two.Smiths.v. Artemis/ref> She would often roam the forests of Greece, attended by her large entourage, mostly made up of nymphs, some mortals, and hunters. The goddess Diana is her Roman equivalent. In Greek tradition, Artemis is the daughter of the sky god and king of gods Zeus and Leto, and the twin sister of Apollo. In most accounts, the twins are the products of an extramarital liaison. For this, Zeus' wife Hera forbade Leto from giving birth anywhere on land. Only the island of Delos gave refuge to Leto, allowing her to give birth to her children. Usually, Artemis is ...

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 ...

Deep Space Exploration
Deep space exploration (or deep-space exploration) is the branch of astronomy, astronautics and space technology that is involved with exploring the distant regions of outer space. However, there is little consensus on the meaning of "distant" regions. In some contexts, it is used to refer to interstellar space. The International Telecommunication Union defines "deep space" to start at a distance of 2 million km (approximately 0.01 AU) from the Earth's surface. NASA's Deep Space Network has variously used criteria of 16,000 to 32,000 km from Earth. Physical exploration of space is conducted both by human spaceflights (deep-space astronautics) and by robotic spacecraft. At present the farthest space probe humankind has constructed and launched from Earth is ''Voyager 1'', which was announced on December 5, 2011, to have reached the outer edge of the Solar System, and entered interstellar space on August 25, 2012. Deep space exploration further than this vessel's capacity is not yet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Exploration Upper Stage
The Exploration Upper Stage (EUS) is being developed as a large second stage for Block 1B and Block 2 of the Space Launch System (SLS), succeeding Block 1's Interim Cryogenic Propulsion Stage. It will be powered by four RL10C-3 engines burning liquid oxygen and liquid hydrogen to produce a total thrust of . , the SLS Block 1B will have a payload capacity to low Earth orbit of and Block 2 will have a payload capacity of . The EUS is expected to first fly on Artemis IV in March 2026. Development The Block 1 configuration of SLS has a core stage powered by four RS-25 engines, two Space Shuttle-derived five-segment solid rocket boosters, and an Interim Cryogenic Propulsion Stage (ICPS) upper stage. NASA will develop the EUS to increase SLS performance beyond Block 1 specifications. The improved upper stage was originally named the Dual Use Upper Stage (DUUS, pronounced "duce") but was later renamed the Exploration Upper Stage (EUS) due to DUUS sounding lik ...

SLS Block 1B
The Space Launch System (SLS) is an American super heavy-lift expendable launch vehicle developed by NASA. As of 2022, SLS has the highest payload capacity of any rocket in operational service, as well as the greatest liftoff thrust of any rocket in operation. As the primary launch vehicle of the Artemis moon landing program, SLS is designed to launch the crewed Orion spacecraft on a trans-lunar trajectory. The first uncrewed launch, Artemis 1, took place on 16 November 2022. Development of SLS began in 2011, as a replacement for the retired Space Shuttle as well as the cancelled Ares I and Ares V launch vehicles. As a Shuttle-derived vehicle, the Space Launch System reuses hardware from the Space Shuttle program, including the solid rocket boosters and RS-25 first stage engines. An original flight date of late 2016 was delayed by nearly 6 years. The SLS program has attracted criticism for such delays, high cost, and non-competitive use of Space Shuttle components ...

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. Three flights of the Orion Multi-Purpose Crew Vehicle are currently planned for launch in the Artemis program in the early 2020s, beginning with Artemis 1. Before Artemis was named, the flights were referred to as "Orion missions". Numerous supporting scientific and technology demonstration missions are planned for launch under the program's Commercial Lunar Payload Services (CLPS), in addition to planned and proposed uncrewed logistical missions to construct and resupply the Gateway and its expendable and reusable lunar landers in lunar orbit. Main missions Support missions Technology demonstrations Launched June 28 2022, the Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment ("CAPSTONE") mission is a small (25 kg) technology-demonstra ...

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] |
Lunar Rover
A lunar rover or Moon rover is a space exploration vehicle designed to move across the surface of the Moon. The Apollo Program's Lunar Roving Vehicle was driven on the Moon by members of three American crews, Apollo 15, 16, and 17. Other rovers have been partially or fully autonomous robots, such as the Soviet Union's Lunokhods and the Chinese '' Yutus''. Three countries have had operating rovers on the Moon: the Soviet Union, the United States and China. An Indian mission failed while Japan and Greece currently have planned missions. Past missions Lunokhod 1 Lunokhod 1 (Луноход) was the first of two polycrystalline-panel-powered robotic lunar rovers landed on the Moon by the Soviet Union as part of its Lunokhod program after a previous unsuccessful attempt of a launch probe with Lunokhod 0 (No.201) in 1969. The spacecraft which carried Lunokhod 1 was named Luna 17. The spacecraft soft-landed on the Moon in the Sea of Rains on November 1970. Lunokhod was the first ...
