Al-Khwarizmi (crater)
Al-Khwarizmi is a lunar impact crater located on the far side of the Moon. It lies to the southeast of the crater Moiseev, and northeast of Saenger. The western inner wall of Al-Khwarizmi is much wider than along the eastern side. The eastern rim overlays a pair of craters, including Al-Khwarizmi J. The outer wall is somewhat distorted from a circular shape, including a double-rim in the south. There is a small central peak at the midpoint, which forms part of a low ridge that bends to the northeast. Several tiny craterlets lie in the northern part of the interior floor. The floor to the southeast is somewhat smoother and free of significant impacts. The crater was named for the Persian mathematician and astronomer Muhammad ibn Musa al-Khwarizmi. 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 Al-Khwarizmi.

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 ...

Persian People
The Persians are an Iranian ethnic group who comprise over half of the population of Iran. They share a common cultural system and are native speakers of the Persian language as well as of the languages that are closely related to Persian. The ancient Persians were originally an ancient Iranian people who had migrated to the region of Persis (corresponding to the modern-day Iranian province of Fars) by the 9th century BCE. Together with their compatriot allies, they established and ruled some of the world's most powerful empires that are well-recognized for their massive cultural, political, and social influence, which covered much of the territory and population of the ancient world.. Throughout history, the Persian people have contributed greatly to art and science. Persian literature is one of the world's most prominent literary traditions. In contemporary terminology, people from Afghanistan, Tajikistan, and Uzbekistan who natively speak the Persian language are know ...

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 ...

Farouk El-Baz
Farouk El-Baz ( arz, فاروق الباز, ''Pronunciation'': ) (born January 2, 1938) is an Egyptian American space scientist and geologist, who worked with NASA in the scientific exploration of the Moon and the planning of the Apollo program. He was a leading geologist on the program, responsible for studying the geology of the Moon, the selection of landing sites for the Apollo missions, and the training of astronauts in lunar observations and photography. He played a key role in the Apollo 11 Moon landing mission, and later Apollo missions. He also came up with the idea of touchable Moon rocks at a museum, inspired by his childhood pilgrimage to Mecca where he touched the Black Stone (which in Islam is believed to be sent down from the heavens). He is married, has four daughters, and has six grandchildren. He was a Senior Advisor to Egypt's former president Hosni Mubarak.

Apollo 11
Apollo 11 (July 16–24, 1969) was the American spaceflight that first landed humans on the Moon. Commander Neil Armstrong and lunar module pilot Buzz Aldrin landed the Apollo Lunar Module ''Eagle'' on July 20, 1969, at 20:17 UTC, and Armstrong became the first person to step onto the Moon's surface six hours and 39 minutes later, on July 21 at 02:56 UTC. Aldrin joined him 19 minutes later, and they spent about two and a quarter hours together exploring the site they had named Tranquility Base upon landing. Armstrong and Aldrin collected of lunar material to bring back to Earth as pilot Michael Collins flew the Command Module ''Columbia'' in lunar orbit, and were on the Moon's surface for 21 hours, 36 minutes before lifting off to rejoin ''Columbia''. Apollo 11 was launched by a Saturn V rocket from Kennedy Space Center on Merritt Island, Florida, on July 16 at 13:32 UTC, and it was the fifth crewed mission of NASA's Apollo program.

Saenger (crater)
Saenger is an ancient Lunar craters, lunar impact crater that lies on the Far side (Moon), far side of the Moon, just beyond the eastern limb. It was named after Austrian rocketry scientist Eugen Sänger. To the west-northwest is the crater Erro (crater), Erro, and due north lies Moiseev (crater), Moiseev. To the northeast is Al-Khwarizmi (crater), Al-Khwarizmi. The outer rim of Saenger has been eroded and reshaped by subsequent impacts, leaving the outer wall nearly destroyed to the north and south. The satellite crater Saenger D is adjacent to the interior of the northeastern rim. To the west, Saenger V lies across the northwestern rim, while the crater pair Saenger P and Q lie across and intrude into the southwestern rim. In contrast, the interior floor is relatively flat and featureless, with only tiny craterlets to mark the surface. Satellite craters By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is clos ...

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 ...

Moiseev (crater)
Moiseev is a lunar impact crater that is located just on the far side of the Moon. It lies to the south-southwest of the slightly larger crater Hertz, and north of Saenger. To the southeast lies the irregular crater Al-Khwarizmi. Moiseev overlies the southern rim of the larger satellite formation Moiseev Z. The crater is not significantly worn, and is marked only by a few tiny craterlets in the interior. The rim is generally circular, but has an outward bulge and a wider interior wall to the west-southwest. There are some terrace structures around the inner eastern wall, while the western inner wall has more of a slumped appearance. At the midpoint of the flattened interior is a formation of low hills forming the crater's central peak complex. Naming The crater is named after Soviet astronomer Nikolay Moiseyev. Prior to naming in 1970 by the IAU The International Astronomical Union (IAU; french: link=yes, Union astronomique internationale, UAI) is a nongovernmental organisa ...
