Behaim (crater)
Behaim is a lunar impact crater that is located near the eastern limb of the Moon, just to the south of the crater Ansgarius. To the south of Behaim is the crater Hecataeus, and to the east-southeast is Gibbs. The inner walls along the rim of Behaim still displays traces of old, worn terrace Terrace may refer to: Landforms and construction * Fluvial terrace, a natural, flat surface that borders and lies above the floodplain of a stream or river * Terrace, a street suffix * Terrace, the portion of a lot between the public sidewalk a ...s. The rim has received a negligible amount of wear from subsequent bombardment, but does not form a circular shape due to an inward bulge along the northern wall. The crater has a notable central peak at the midpoint of the interior floor. A cleft-like feature crosses the southern rim and continues to the south. Behaim is similar in appearance to Alpetragius crater near the center of the near side, although Behaim is larger. Satellite cr ...

Apollo 15
Apollo 15 (July 26August 7, 1971) was the ninth crewed mission in the United States' Apollo program and the fourth to Moon landing, land on the Moon. It was the first List of Apollo missions#Alphabetical mission types, J mission, with a longer stay on the Moon and a greater focus on science than earlier landings. Apollo 15 saw the first use of the Lunar Roving Vehicle. The mission began on July 26 and ended on August 7, with the lunar surface exploration taking place between July 30 and August 2. Apollo Commander, Commander David Scott and Lunar Module Pilot James Irwin landed near Hadley–Apennine#Rima Hadley, Hadley Rille and explored the local area using the rover, allowing them to travel further from the Apollo Lunar Module, lunar module than had been possible on previous missions. They spent 18 hours on the Moon's surface on four extravehicular activities (EVA), and collected of surface material. At the same time, Command Module Pilot Alfred Worden orbited the Moo ...

Gibbs (crater)
Gibbs is a lunar impact crater that lies near the eastern limb of the Moon. It is situated less than a crater diameter to the northeast of the larger crater Hecataeus. The crater chain Catena Humboldt passes to the south of Gibbs, following a line to the northeast. Due to its proximity to the limb, this crater appears foreshortened when viewed from the Earth, and visibility is subject to libration. The outer rim of Gibbs is not quite circular, and an outward bulge to the north gives it an onion-like profile. The southeastern wall is slightly straightened and there is a low break in the rim at the southern and northern ends. In other respects, however, the rim is only slightly eroded. The interior floor is nearly level in the southwestern half, with irregular ridges to the northeast. There is a small craterlet to the northwest of the midpoint. A recent small impact along the northeastern rim has produced a small ray system that forms a skirt of higher albedo Albedo (; ) is t ...

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 campaigne ...

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 ...

Alpetragius (crater)
Alpetragius is a lunar impact crater located on the eastern edge of Mare Nubium, to the southwest of the much larger crater Alphonsus. In the southeast is the prominent crater Arzachel, and to the west lies the flooded Lassell. Alpetragius is a Latinization of the name of Nur ad-Din al-Bitruji, a Spanish-Arab astronomer. The most notable feature of this crater is the disproportionately large central peak, which forms a rounded rise that occupies almost the entire crater floor—one-third the crater diameter—and rises to a height of 2.0 km. There is evidence that this peak has been enlarged through volcanic eruptions, and there appears to be an eroded vent at its summit. The rim has fine terraces that slope down to near the edge of the central rise along the south and east sides. This outer wall is nearly round, with slight protrusions on the north and west sides. The outer rim is joined to the southwest rim of Alphonsus by a rise in the surface. An arc of cra ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Hecataeus (crater)
Hecataeus is a large Lunar craters, lunar impact crater that lies near the eastern limb of the Moon. It is attached to the northern rim of the walled plain Humboldt (crater), Humboldt. To the northeast is the smaller crater Gibbs (crater), Gibbs. East of Hecataeus is a chain of small craters forming a line radial to Humboldt; these are designated the Catena Humboldt, named after the walled plain. Hecataeus is a worn and eroded walled plain with wide inner walls. Its northern part overlies half of Hecataeus K, a fairly substantial crater. Along the southern rim, the outer wikt:rampart, rampart of ejecta from Humboldt forms a rugged interior surface across the southern floor. Several small, bowl-shaped craters lay across the eastern rim and inner wall. The western rim is much less damaged by impacts, although it is still eroded. The northern part of the interior floor is relatively featureless. The crater was named after Hecataeus of Miletus by the IAU in 1935. Satellite craters By ...

Martin Behaim
Martin Behaim (6 October 1459 – 29 July 1507), also known as and by various forms of , was a German textile merchant and cartographer. He served John II of Portugal as an adviser in matters of navigation and participated in a voyage to West Africa. He is now best known for his Erdapfel, the world's oldest surviving globe, which he produced for the Imperial City of Nuremberg in 1492. Biography Behaim was born in Nuremberg on 6 October 1459, the oldest son of Martin Behaim and Agnes Schopper. The elder Martin was a merchant involved in long-distance trade within Europe, including Venice; in 1461 he was elected a senator of Nuremberg. Their son, as a member of a prominent and prosperous family, likely received a good education at one of the best grammar schools in the city. Contrary to later assertions, it is unlikely that he was ever a student of the famous Renaissance mathematician and astronomer, Regiomontanus.Görz, 2007Ravenstein, 1908 When his father died in 1474, Mar ...

Ansgarius (crater)
Ansgarius is a lunar impact crater that is located near the eastern limb of the Moon. When viewed from the Earth, the crater has a highly oval shape due to foreshortening, but the rim is actually nearly circular. To the northwest of Ansgarius is the crater La Pérouse, and south is Behaim. The rim of Ansgarius is not significantly worn, and has a terraced interior surface. The southwest rim appears somewhat flattened rather than round, and intrudes into an older formation of which little remains except the western rim. There is an outward notch in the north-northeastern wall. The interior floor of Ansgarius is relatively flat, with only tiny craterlets to mark the surface. Ansgarius was named after Saint Ansgar, a 9th-century Benedictine missionary monk who brought Catholicism to northern Germany and Scandinavia, known as the "Apostle of the North". The crater's name was approved by the IAU The International Astronomical Union (IAU; french: link=yes, Union astronomique int ...
