Cysatus (crater)
Cysatus is a lunar impact crater that is located in the southern part of the Moon's near side. It is joined to the northeastern rim of the larger crater Gruemberger, and intrudes slightly into the interior of that formation. Due south is the larger Moretus, and to the east is Curtius. These craters appear foreshortened when observed from Earth because of their far south location. This circular crater is slightly unusual for its lack of interesting features. No notable craters lie along its rim or the flat, level interior. The inner walls are devoid of 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 and just slope down to the flat floor, although the width of the inner wall is narrower to the northeast than elsewhere.

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 ...

Earth
Earth is the third planet from the Sun and the only astronomical object known to harbor life. While large volumes of water can be found throughout the Solar System, only Earth sustains liquid surface water. About 71% of Earth's surface is made up of the ocean, dwarfing Earth's polar ice, lakes, and rivers. The remaining 29% of Earth's surface is land, consisting of continents and islands. Earth's surface layer is formed of several slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Earth's liquid outer core generates the magnetic field that shapes the magnetosphere of the Earth, deflecting destructive solar winds. The atmosphere of the Earth consists mostly of nitrogen and oxygen. Greenhouse gases in the atmosphere like carbon dioxide (CO2) trap a part of the energy from the Sun close to the surface. Water vapor is widely present in the atmosphere and forms clouds that cover most of the planet. More solar e ... [...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 ...

Curtius (crater)
Curtius is a lunar impact crater that is located in the southern part of the Moon. From the Earth the crater appears foreshortened, making it more difficult to observe detail. Nevertheless, this is a large crater that can be readily found in even small telescopes. Curtius is located within one crater diameter of the still-larger Moretus to the southwest. To the northeast is the smaller Pentland. Curtius is 95 kilometers in diameter and 6.8 kilometers deep. It is from the Nectarian period, 3.92 to 3.85 billion years ago. It is named after Albert Curtz Albert Curtz (''Curtius'' in Latin; 1600, Munich – December 19, 1671, Munich), was a German astronomer and member of the Society of Jesus. He expanded on the works of Tycho Brahe and used the pseudonym of ''Lucius Barrettus''. Background The L .... Background The outer rim of Curtius has been softened due to impact erosion, but it retains much of its original structure. Along the north and northwest parts of the rim are a pa ...

Jean-Baptiste Cysat
Johann Baptist Cysat (Latinized as Cysatus; in French, Jean-Baptiste Cysat) (c. 1587 – March 17, 1657) was a Swiss Jesuit mathematician and astronomer, after whom the lunar crater Cysatus is named. He was born in Lucerne, as the eighth of 14 children, to cartographer, historian and folklorist Renward Cysat (1545–1614). In 1604, Cysat joined the Jesuits and became a theology student in March 1611 in Ingolstadt. There he met Christoph Scheiner, whom he assisted in the latter’s observation of sunspots, whose discovery would later become a matter of dispute between Galileo and Scheiner. In 1618, Cysat was named professor of mathematics at the University of Ingolstadt, succeeding Scheiner in this position, thereby allowing him to concern himself further with astronomical problems. Cysat became one of the first to make use of the newly developed telescope. Cysat and comets Cysat's most important work was on comets, and he observed the comet of 1618. He published a monogr ...

Moretus (crater)
Moretus is a lunar impact crater located in the heavily cratered highland region near the south pole of the Moon. South of Moretus, the crater Short is located, while to the north is Cysatus. To the northwest lies Gruemberger, and Curtius is located to the northeast. Due to the location near the lunar limb, the crater appears oblong because of foreshortening. The crater is named after the 17th-century Flemish mathematician and geometer Theodorus Moretus. The rim of the crater has a wide, terraced inner wall, and a complex outer rampart Rampart may refer to: * Rampart (fortification), a defensive wall or bank around a castle, fort or settlement Rampart may also refer to: * "O'er the Ramparts We Watched" is a key line from "The Star-Spangled Banner", the national anthem of the ....

Gruemberger (crater)
Gruemberger is an old impact crater in the southern part of the Moon. When viewed from the Earth this crater appears oval in shape due to foreshortening, but it is actually relatively circular. The crater lies about 25 kilometers to the north-northwest of the larger and more prominent crater Moretus. The smaller crater Cysatus intrudes into the eastern rim of Gruemberger. About one and a half crater diameters to the north is the large crater Clavius Christopher Clavius, SJ (25 March 1538 – 6 February 1612) was a Jesuit German mathematician, head of mathematicians at the Collegio Romano, and astronomer who was a member of the Vatican commission that accepted the proposed calendar inve .... This crater has undergone steady erosion from minor impacts, so that the features along the rim and inner wall have become softened and rounded. Significant impacts nearby have covered the floor and sides with ejecta, and there are a multitude of tiny craterlets along the inner wall. ...
