Draper (crater)
Draper is a small lunar impact crater in the southern part of the Mare Imbrium. It is a circular, cup-shaped formation, with a tiny craterlet intruding into the northeastern rim. To the north-northeast is the crater Pytheas Pytheas of Massalia (; Ancient Greek: Πυθέας ὁ Μασσαλιώτης ''Pythéas ho Massaliōtēs''; Latin: ''Pytheas Massiliensis''; born 350 BC, 320–306 BC) was a Greeks, Greek List of Graeco-Roman geographers, geographer, explor ..., and to the south lies the Montes Carpatus range. Just to the southeast is the slightly smaller crater identified as Draper C. The crater is named after American astronomer Henry Draper. 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 Draper.

Lunar Orbiter 4
Lunar Orbiter 4 was a robotic U.S. spacecraft, part of the Lunar Orbiter program, Lunar Orbiter Program, designed to orbit the Moon, after the three previous orbiters had completed the required needs for Project Apollo, Apollo mapping and site selection. It was given a more general objective, to "perform a broad systematic photographic survey of lunar surface features in order to increase the scientific knowledge of their nature, origin, and processes, and to serve as a basis for selecting sites for more detailed scientific study by subsequent orbital and landing missions". It was also equipped to collect selenodetic, radiation intensity, and micrometeoroid impact data. Mission Summary The spacecraft was placed in a Free-return trajectory, cislunar trajectory and injected into an elliptical near polar high lunar orbit for data acquisition. The orbit was with an inclination of 85.5 degrees and a period of 12 hours. After initial photography on May 11, 1967 problems started occu ...

Henry Draper
Henry Draper (March 7, 1837 – November 20, 1882) was an American doctor and amateur astronomer. He is best known today as a pioneer of astrophotography. Life and work Henry Draper's father, John William Draper, was an accomplished doctor, chemist, botanist, and professor at New York University; he was also the first to photograph the moon through a telescope (1840). Draper's mother was Antonia Coetana de Paiva Pereira Gardner, daughter of the personal physician to the Emperor of Brazil. His niece, Antonia Maury was also an astronomer. He graduated from New York University School of Medicine, at the age of 20, in 1857. He worked first as a physician at Bellevue Hospital, and later as both a professor and dean of medicine at New York University (NYU). On May 31, 1862, he joined S Company, 12th New York Infantry Regiment as a surgeon along with his brother John Christopher, who joined as an assistant surgeon.Hughes, Stefan''Catchers of the Light, Volume 1 - Catching Space'' Ar ...

Montes Carpatus-A
Mons (; German and nl, Bergen, ; Walloon and pcd, Mont) is a city and municipality of Wallonia, and the capital of the province of Hainaut, Belgium. Mons was made into a fortified city by Count Baldwin IV of Hainaut in the 12th century. The population grew quickly, trade flourished, and several commercial buildings were erected near the ''Grand’Place''. In 1814, King William I of the Netherlands increased the fortifications, following the fall of the First French Empire. The Industrial Revolution and coal mining made Mons a centre of heavy industry. In 1830, Belgium gained its independence and the decision was made to dismantle the fortifications, allowing the creation of large boulevards and other urban projects. On 2324 August 1914, Mons was the location of the Battle of Mons. The British were forced to retreat and the town remained occupied by the Germans until its liberation by the Canadian Corps during the final days of the war. There are several memorial placards ...

Lunar Craters
Lunar craters are impact craters on Earth's Moon. The Moon's surface has many craters, all of which were formed by impacts. The International Astronomical Union currently recognizes 9,137 craters, of which 1,675 have been dated. History The word ''crater'' was adopted from the Greek word for "vessel" (, a Greek vessel used to mix wine and water). Galileo built his first telescope in late 1609, and turned it to the Moon for the first time on November 30, 1609. He discovered that, contrary to general opinion at that time, the Moon was not a perfect sphere, but had both mountains and cup-like depressions. These were named craters by Johann Hieronymus Schröter (1791), extending its previous use with volcanoes. Robert Hooke in ''Micrographia'' (1665) proposed two hypotheses for lunar crater formation: one, that the craters were caused by projectile bombardment from space, the other, that they were the products of subterranean lunar volcanism. Scientific opinion as to the origin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Impact Crater
An impact crater is a circular depression in the surface of a solid astronomical object formed by the hypervelocity impact of a smaller object. In contrast to volcanic craters, which result from explosion or internal collapse, impact craters typically have raised rims and floors that are lower in elevation than the surrounding terrain. Lunar impact craters range from microscopic craters on lunar rocks returned by the Apollo Program and small, simple, bowl-shaped depressions in the lunar regolith to large, complex, multi-ringed impact basins. Meteor Crater is a well-known example of a small impact crater on Earth. Impact craters are the dominant geographic features on many solid Solar System objects including the Moon, Mercury, Callisto, Ganymede and most small moons and asteroids. On other planets and moons that experience more active surface geological processes, such as Earth, Venus, Europa, Io and Titan, visible impact craters are less common because they become eroded ...

Mare Imbrium
Mare Imbrium (Latin ''imbrium'', the "Sea of Showers" or "Sea of Rains", "Sea of Tears") is a vast lava plain within the Imbrium Basin on the Moon and is one of the larger craters in the Solar System. The Imbrium Basin formed from the collision of a proto-planet during the Late Heavy Bombardment. Basaltic lava later flooded the giant crater to form the flat volcanic plain seen today. The basin's age has been estimated using uranium–lead dating methods to approximately 3.9 billion years ago, and the diameter of the impactor has been estimated to be 250 ± 25 km. The Moon's maria (plural of mare) have fewer features than other areas of the Moon because molten lava pooled in the craters and formed a relatively smooth surface. Mare Imbrium is not as flat as it was originally thought, because later events have altered its surface. Origin Mare Imbrium formed when a proto-planet from the asteroid belt collided with the moon during the Late Heavy Bombardment. The impact i ...

Pytheas (crater)
Pytheas is a small Lunar craters, lunar impact crater located on the southern part of the Mare Imbrium, to the south of the crater Lambert (lunar crater), Lambert. It was named after ancient Greek navigator and geographer Pytheas of Massalia. It has a sharply defined rim, a hummocky outer wikt:rampart, rampart, and an irregular interior due to slumping or fall-back. There is a small crater along the northern outer wikt:rampart, rampart, and a similar crater about 20 km to the west. The crater possesses a small ray system that extends for a radius of about 50 kilometers. It is surrounded by lunar mare that is dusted with ray material from Copernicus (lunar crater), Copernicus to the south. 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 Pytheas.

Montes Carpatus
Montes Carpatus is a mountain range that forms the southern edge of the Mare Imbrium on the Moon. The selenographic coordinates of this range are 14.5° N, 24.4° W, and the formation has an overall diameter of . They were named by astronomer Johann Heinrich von Mädler after the Carpathian Mountains in Central Europe. Description This rugged range generally stretches from west to east. The western end begins in the vicinity of the crater T. Mayer (crater), T. Mayer, although a few low ridges curve northwards towards Euler (crater), Euler crater. At the eastern extreme is a wide gap where Mare Imbrium in the north joins Mare Insularum to the south. Starting at the east side of this gap are the Montes Apenninus, another mountainous range that curves up towards the northeast. Most of this range consists of a series of peaks and rises, separated by valleys that have been penetrated by lava flows. None of the peaks have received individual names, unless one includes Mons Vinogradov ... [...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 ...

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 ...
