Dollond (crater)
Dollond is a small Lunar craters, lunar impact crater that is located in the central region of the Moon, to the north of the crater Abulfeda (crater), Abulfeda. It was named after British optician John Dollond. Due west of Dollond is Anděl (crater), Anděl. Dollond is circular and cone shaped, with a tiny floor at the midpoint of the sloping interior walls. About 50 kilometers to the northeast of this crater was the landing site of the Apollo 16 mission, the next-to-last of the Apollo expeditions to the Moon. 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 Dollond. The following craters have been renamed by the International Astronomical Union, IAU. * Dolland C — ''See'' Lindsay (crater), Lindsay. Dollond T is the closest named feature to the Apollo 16 landing site, other than the features that were named by the astronauts (such as North Ray (crater), North Ray and S ...

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 return to E ...

Lindsay (crater)
Lindsay is a small lunar impact crater in the central highlands of the Moon. It was named after the Irish astronomer Eric Mervyn Lindsay. It lies in the irregular terrain to the northwest of the landing site of the Apollo 16 mission. To the south is the crater Anděl, and Taylor is to the east-northeast. Dr E. J. Öpik stated that this crater was likely formed by the impact of an asteroid about 1 mile (1.6 km) in diameter. The outer rim of this crater is worn and irregular, with incisions along the northern and southern inner walls. There is a cleft in the southeastern rim that links with the slightly larger Dollond B. The interior floor is level and is crossed by a crater chain and a slender cleft at the west end. This crater was designated Dollond C before being given its current name by the IAU The International Astronomical Union (IAU; french: link=yes, Union astronomique internationale, UAI) is a nongovernmental organisation with the objective of advancing as ...

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 ...

South Ray (crater)
South Ray crater is a small crater in the Descartes Highlands of the Moon photographed from the lunar surface by the astronauts of Apollo 16. The name of the crater was formally adopted by the IAU in 1973. The Apollo 16 Lunar Module (LM) ''Orion'' landed between North Ray and South Ray craters on April 21, 1972. The astronauts John Young and Charles Duke explored the area between the craters over the course of three EVAs using a Lunar Roving Vehicle, or rover. They came closest to South Ray on EVA 2, at station 4 ( Cinco crater), about 3.9 km south of the landing site. Duke photographed South Ray from there with a 500-mm lens. South Ray crater is approximately 700 m in diameter and approximately 120 m deep, with a bright system of rays of ejecta. The astronauts observed that the ejecta of South Ray was very bouldery, and reported that it would have been difficult or impossible to drive there on their rover.

North Ray (crater)
North Ray crater is a small crater in the Descartes Highlands of the Moon visited by the astronauts of Apollo 16. The name of the crater was formally adopted by the IAU in 1973. It is the largest crater sampled by astronauts during the Apollo program. The Apollo 16 Apollo Lunar Module, Lunar Module (LM) ''Orion'' landed between North Ray and South Ray (crater), South Ray craters on April 21, 1972. The astronauts John Young (astronaut), John Young and Charles Duke explored the area between the craters over the course of three Extra-vehicular activity, EVAs using a Lunar Roving Vehicle, or rover. They visited North Ray on EVA 3, at station 11, about 4.4 km north of the landing site. On the way, they drove along the rim of the similar sized but older crater Palmetto (crater), Palmetto, which is approximately 3 km south of North Ray. North Ray crater is approximately 1 km in diameter and approximately 240 m deep. The astronauts observed that the upper 50 m of the s ...

John Dollond
John Dollond FRS (10 June O.S. (21 June N.S.) 170630 November 1761) was an English optician, known for his successful optics business and his patenting and commercialization of achromatic doublets. Biography Dollond was the son of a Huguenot refugee, a silk-weaver at Spitalfields, London, where he was born. He followed his father's trade, but found time to acquire a knowledge of Latin, Greek, mathematics, physics, anatomy and other subjects. In 1752 he abandoned silk-weaving and joined his eldest son, Peter Dollond (1730–1820), who in 1750 had started in business as a maker of optical instruments; this business went on to become Dollond & Aitchison. His reputation grew rapidly, and in 1761 he was appointed optician to the king. In 1758 he published an "Account of some experiments concerning the different refrangibility of light" ('' Phil. Trans.'', 1758), describing the experiments that led him to the achievement with which his name is specially associated, the discovery ...

Anděl (crater)
Anděl is a lunar impact crater that lies in the rugged central highlands of the Moon. It was named after the Czech astronomer Karel Anděl. Nearby craters of note include Abulfeda to the south-southeast and Descartes to the east-southeast. About 85 kilometres to the east-northeast of the outer rim is the landing site of the Apollo 16 mission. The eroded outer rim of Anděl has been worn and distorted into a polygon In geometry, a polygon () is a plane figure that is described by a finite number of straight line segments connected to form a closed ''polygonal chain'' (or ''polygonal circuit''). The bounded plane region, the bounding circuit, or the two to ...al shape, and is nearly non-existent to the south where Anděl G intersects the perimeter. The interior floor is nearly flat, with some irregularities to the southeast. There is a tiny craterlet located just to the southeast of the midpoint, but no central peak of any significance.
