Bragg (crater)
Bragg is an ancient lunar impact crater that is located on the far side of the Moon, just beyond the northwest limb. This formation has been heavily eroded and reshaped by subsequent impacts, leaving an irregular depression in the surface. The most intact portion of the rim is along the western face, while the northern and eastern rim has been nearly worn away and is overlaid by several smaller craters. The most notable of these is Bragg H, which lies across the east-southeastern rim. This crater is located to the north-northwest of the walled plain Lorentz. Nearby craters of note include Rynin to the north, Stefan to the northwest, Lacchini to the west, and Avicenna Ibn Sina ( fa, ابن سینا; 980 – June 1037 CE), commonly known in the West as Avicenna (), was a Persian polymath who is regarded as one of the most significant physicians, astronomers, philosophers, and writers of the Islamic G ... to the southeast. The region about this crater is very rugged a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clementine (spacecraft)
''Clementine'' (officially called the Deep Space Program Science Experiment (DSPSE)) was a joint space project between the Ballistic Missile Defense Organization (previously the Strategic Defense Initiative Organization) and NASA, launched on January 25, 1994. Its objective was to test sensors and spacecraft components in long-term exposure to space and to make scientific observations of both the Moon and the near-Earth asteroid 1620 Geographos. Results Observation of the asteroid was not made due to a malfunction in the spacecraft. The lunar observations included imaging at various wavelengths in the visible as well as in ultraviolet and infrared, laser ranging altimetry, gravimetry, and charged particle measurements. These observations were for the purposes of obtaining multi-spectral imaging of the entire lunar surface, assessing the surface mineralogy of the Moon, obtaining altimetry from 60N to 60S latitude, and obtaining gravity data for the near side. There were als ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lacchini (crater)
Lacchini is an impact crater on the far side of the Moon. It is located in the northern hemisphere, just behind the northwestern limb of the visible Moon. This part of the lunar surface can sometimes be viewed under favorable conditions of libration and illumination, but at such times the crater is only seen from the edge. Less than one crater diameter to the east is the larger crater Bragg. To the north is Stefan, and farther to the southeast is the walled plain Lorentz. Due west of Laccini is Landau Landau ( pfl, Landach), officially Landau in der Pfalz, is an autonomous (''kreisfrei'') town surrounded by the Südliche Weinstraße ("Southern Wine Route") district of southern Rhineland-Palatinate, Germany. It is a university town (since 1990 ..., another walled plain. The outer rim of Lacchini is roughly circular, with outward bulges to the south and east. The edge is sharp and not significantly eroded. The inner walls have slumped around much of the circumference, formi ... [...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 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 ...

Avicenna (crater)
Avicenna is a Lunar craters, lunar impact crater that lies on the Far side (Moon), far side of the Moon, just beyond the western limb on the northern rim of the Lorentz (crater), Lorentz basin. It is named after the Persian people, Persian polymath Avicenna. It lies to the north-northwest of the larger crater Nernst (crater), Nernst, and to the southeast of Bragg (crater), Bragg. The northern half of Avicenna has been obliterated by subsequent, overlapping impacts. The southern and southeastern rim is worn and eroded, but the outline can still be discerned. There is a small crater lying across the southern rim, although this formation is equally worn. Several small craters lie across the southern extent of Avicenna's floor. 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 Avicenna.

Stefan (crater)
Stefan is a lunar impact crater on the far side of the Moon, just beyond the northwestern limb. Attached to the western rim is the slightly smaller crater Wegener, and close to the eastern rim is Rynin. As with many craters of this size on the Moon, the outer rim has been worn by impact erosion and the edge and inner wall are generally pitted with small craterlets. The southern edge of the rim in particular has been damaged by impacts, and is overlain by the satellite crater Stefan L. This bowl-shaped crater lies at the center of a small ray system, which is indicative of a relatively young impact. The interior floor of Stefan is a generally level surface that is marked by several impacts. The most notable is a ring-shaped crater rim projecting up through the southern half of the floor. Near the midpoint is a low hill, possibly the buried remnant of a central peak. Stefan lies at the approximate margin of the Coulomb-Sarton Basin, a 530 km wide impact crater of Pre-Necta ...

William Henry Bragg
Sir William Henry Bragg (2 July 1862 – 12 March 1942) was an English physicist, chemist, mathematician, and active sportsman who uniquelyThis is still a unique accomplishment, because no other parent-child combination has yet shared a Nobel Prize (in any field). In several cases, a parent has won a Nobel Prize, and then years later, the child has won the Nobel Prize for separate research. An example of this is with Marie Curie and her daughter Irène Joliot-Curie, who are the only mother-daughter pair. Several father-son pairs have won two separate Nobel Prizes. shared a Nobel Prize with his son Lawrence Bragg – the 1915 Nobel Prize in Physics: ''"for their services in the analysis of crystal structure by means of X-rays"''. The mineral Braggite is named after him and his son. He was knighted in 1920. Biography Early years Bragg was born at Westward, near Wigton, Cumberland, England, the son of Robert John Bragg, a merchant marine officer and farmer, and his wife Mary nà ...

Rynin (crater)
Rynin is a lunar impact crater that is located just behind the northwestern limb, on the far side of the Moon The Moon is Earth's only natural satellite. It is the fifth largest satellite in the Solar System and the largest and most massive relative to its parent planet, with a diameter about one-quarter that of Earth (comparable to the width of .... It is located just to the east of the larger crater Stefan, and to the southwest of Chapman. This is an older lunar crater with an outer rim that has been worn and rounded due to impact erosion. The edge remains relatively well-defined around most of the perimeter, but it is overlain by several smaller craters. Along the eastern side is a long, dagger-shaped gash that cuts through the rim and inner wall to reach the interior floor. This gash is connected to a crater formation just outside the eastern edge of Rynin. A shelf of slumped material runs along the inner wall northward. The western section of the interior floor ...

Lorentz (crater)
Lorentz is a huge lunar impact crater that lies just beyond the northwest limb of the Moon, in a region that is brought into sight of the Earth during favorable librations. This formation is nearly as large as the Mare Nectaris on the near side of the Moon, although it has not been submerged by lava as have the lunar mare. Sections of the crater floor are, however, relatively level, particularly an arc along the western rim. But this last region is still marked by a number of tiny craterlets. The remainder of the interior is rough and irregular, and marked with a multitude of impacts. Lorentz contains a prominent crater pairing, with Nernst located just to the north of Lorentz's midpoint, and Röntgen attached to the southeastern rim of Nernst. Lying across the southern rim of Lorentz is Laue, and Avicenna lies across the northwestern rim. Near the more indeterminate eastern rim of Lorentz is Aston Aston is an area of inner Birmingham, England. Located immediately to the no ...
