Back (crater)
Back is a small lunar impact crater that is located near the eastern limb of the Moon. It lies on the northwest edge of the Mare Smythii, and the northeast rim is adjacent to the crater Schubert. To the west is Jenkins, and to the southwest is the Weierstrass– Van Vleck crater pair. Back is nearly circular, with narrow, sharp-edged outer walls that are not significantly worn. Despite its relatively small size, Back has a central peak typical of larger craters. Back was formally named by the IAU The International Astronomical Union (IAU; french: link=yes, Union astronomique internationale, UAI) is a nongovernmental organisation with the objective of advancing astronomy in all aspects, including promoting astronomical research, outreach ... in 1976.

Apollo 16
Apollo 16 (April 1627, 1972) was the tenth crewed mission in the United States Apollo space program, administered by NASA, and the fifth and penultimate to land on the Moon. It was the second of Apollo's " J missions", with an extended stay on the lunar surface, a focus on science, and the use of the Lunar Roving Vehicle (LRV). The landing and exploration were in the Descartes Highlands, a site chosen because some scientists expected it to be an area formed by volcanic action, though this proved to not be the case. The mission was crewed by Commander John Young, Lunar Module Pilot Charles Duke and Command Module Pilot Ken Mattingly. Launched from the Kennedy Space Center in Florida on April 16, 1972, Apollo 16 experienced a number of minor glitches en route to the Moon. These culminated with a problem with the spaceship's main engine that resulted in a six-hour delay in the Moon landing as NASA managers contemplated having the astronauts abort the mission and retu ...

Van Vleck (crater)
Van Vleck is a lunar impact crater that is located near the northeastern rim of the walled plain Gilbert Gilbert may refer to: People and fictional characters * Gilbert (given name), including a list of people and fictional characters *Gilbert (surname), including a list of people Places Australia * Gilbert River (Queensland) * Gilbert River (South ..., to the west of the Mare Smythii. The similar crater Weierstrass is nearly joined to the northwestern rim of Van Vleck. To the east is the small Carrillo. The rim of this crater is nearly circular with no overlying craters of note, although a small crater abuts against the northeastern side and another along the southern inner wall. The inner sides slope down to a slumped ring of unconsolidated material that encircles the interior floor. There is a small peak just to the north of the crater center. This crater was previously identified as Gilbert M before being assigned a name by the IAU in 1976. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jonathan's Space Report
''Jonathan's Space Report'' (JSR) is a newsletter about the Space Age, hosted at Jonathan's Space Page. It is written by Jonathan McDowell, a Center for Astrophysics Harvard & Smithsonian astrophysicist. It is updated as McDowell's schedule permits, but he tries to publish two issues each month. Originally the website was hosted on a Harvard University account, but was moved in late 2003 to a dedicated domain. Started in 1989, the newsletter reports on recent space launches, International Space Station activities and space craft developments. McDowell's report occasionally corrects NASA's official web sites, or provides additional data on classified launches that aren't available elsewhere. Associated projects on the JSR web site are: * A catalog of all known geosynchronous satellites and their current positions * A listing of satellite launch attempts * A cross-reference between catalog number and international designation of artificial satellites McDowell has long campaig ...

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.

Weierstrass (crater)
Weierstrass is a small lunar impact crater that is attached to the northern rim of the walled plain Gilbert Gilbert may refer to: People and fictional characters * Gilbert (given name), including a list of people and fictional characters *Gilbert (surname), including a list of people Places Australia * Gilbert River (Queensland) * Gilbert River (South ..., in the eastern part of the Moon. It also lies very near the crater Van Vleck, a similar formation just to the southeast that is almost attached to the outer rim. Due to its location, the crater appears foreshortened as seen from the Earth. The crater has an oval-shaped outer rim that is longer along an east–west axis. There are some slumped shelves along the inner walls to the north and south. The interior floor is nearly featureless, with only a few tiny impacts. Neither the rim nor the interior are marked by impact craters of significance. This crater was designated Gilbert N prior to being named by the IAU in 197 ...

Schubert (lunar Crater)
Schubert is a lunar impact crater that lies near the eastern limb of the Moon's near side. It is located northwest of the Mare Smythii, and southwest of the prominent crater Neper. Nearly attached to the southern rim is the crater Back. Schubert is a nearly circular crater formation that has not suffered significant erosion from subsequent impacts, and retains a well-defined rim. The interior surface is generally flat, with a few low hills near the center. Satellite craters By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Schubert. The following craters have been renamed by the IAU. * Schubert B — ''See'' Back (crater). * Schubert Y — ''See'' Nobili (crater). * Schubert Z — ''See'' Jenkins (crater).

Jenkins (crater)
Jenkins is a lunar impact crater that lies along the equator of the Moon, near the eastern limb. It is attached to the eastern rim of the slightly larger crater Schubert X, intruding somewhat into the interior. The crater Nobili is likewise attached to the western rim of Schubert X and intrudes slightly into the interior on that side. The three craters form a linear chain along the equator. This formation was previously designated Schubert Z before being given its current name by the IAU. Schubert itself is located to the northeast of Jenkins. To the east-northeast of Jenkins lies the crater Back, and to the south is the crater pair of Van Vleck and Weierstrass Karl Theodor Wilhelm Weierstrass (german: link=no, Weierstraß ; 31 October 1815 – 19 February 1897) was a German mathematician often cited as the "father of modern analysis".

Mare Smythii
Mare Smythii (Latin for "Smyth's Sea") is a lunar mare located along the equator on the easternmost edge of the Moon's near side. It is named for the 19th-century British astronomer William Henry Smyth. The Smythii basin where the mare is located is of the Pre-Nectarian epoch, while the surrounding features are of the Nectarian system. It is contained within a minimal diameter of , and has been excavated to a depth of . The mare material, which makes up the floor of the mare, is a low alumina basalt, and consists of Upper Imbrian basalt covered by Eratosthenian basalt. Features observed within the basin include wrinkle ridges, submerged "ghost" craters, domes, crater chains, and rilles. The overall shape of the mare is circular, likely the result of a large impact. Further bombardment followed, creating the irregular shape. Subsequent volcanism laid down the mare material. As a result of this sequence, only the northeastern portion and a smaller area in the western central ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
