Mendeleev (crater)
Mendeleev is a large lunar impact crater that is located on the far side of the Moon, as seen from the Earth. The southern rim of this walled plain just crosses the lunar equator. Intruding into the eastern rim of Mendeleev is the crater Schuster. Nearly on the opposite side, the smaller Hartmann intrudes into west-southwestern rim. The crater is named after the Russian chemist Dmitri Mendeleev. Even after formal naming in 1961 by the IAU, the crater was known as ''Basin IX'' until the early 1970s. Description The nearly level interior of Mendeleev contains a number of smaller crater formations which have been given names. These form a rough pentagon formation that covers much of the interior floor. Along the western inner floor, the craters Bergman to the west-northwest and Moissan to the west just make contact with the western inner wall of Mendeleev. Together with Bergman, Fischer to the north-northeast and Richards in the north of Mendeleev form the northern side of th ...

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 retu ...

Richards (lunar Crater)
Richards is a small lunar impact crater that is located in the northern interior of the walled plain Mendeleev, on the far side of the Moon. It lies about half-way between the craters Bergman to the west-southwest and Fischer to the east, both also within Mendeleev's interior. This is a circular, cup-shaped crater with a small interior floor at the midpoint of the sloping inner walls. The interior sides have a higher albedo Albedo (; ) is the measure of the diffuse reflection of solar radiation out of the total solar radiation and measured on a scale from 0, corresponding to a black body that absorbs all incident radiation, to 1, corresponding to a body that refl ... than the surroundings. There is a small crater situated along the north-northeastern edge of the rim. The crater chain named Catena Mendeleev passes just to the west of Richards, continuing in a line of small craters from the southwestern edge of Mendeleev. References * * * * * * * * * * * * {{ ...

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 campaig ...

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 m ...

Tales Of Pirx The Pilot
''Tales of Pirx the Pilot'' is a science fiction stories collection by Polish author Stanisław Lem, about a spaceship pilot named Pirx. The first collection of stories about Pirx was published in 1965 in the Soviet Union in Russian under the title ''Охота на Сэтавра'' ("The Hunt for Setaur"). It was translated in Latvian as ''Petaura medības'' in 1966. In 2009 a Lithuanian publisher ''Eridanas'' published the story as ''Setauro Medžioklė.'' In Poland a more complete collection (as ''Opowieści o pilocie Pirxie'') was published in 1968, and translated to English in two parts (''Tales of Pirx the Pilot'' and ''More Tales of Pirx the Pilot'') in 1979 and 1982. Pirx stories include both philosophical and comic elements. A fragment of "The Hunt for Setaur" was added to the required curriculum for Polish junior-high school students in the 1990s.

Secondary Crater
Secondary craters are impact craters formed by the ejecta that was thrown out of a larger crater. They sometimes form radial crater chains. In addition, secondary craters are often seen as clusters or rays surrounding primary craters. The study of secondary craters exploded around the mid-twentieth century when researchers studying surface craters to predict the age of planetary bodies realized that secondary craters contaminated the crater statistics of a body's crater count. Formation When a velocity-driven extraterrestrial object impacts a relatively stationary body, an impact crater forms. Initial crater(s) to form from the collision are known as primary craters or impact craters. Material expelled from primary craters may form secondary craters (secondaries) under a few conditions: # Primary craters must already be present. # The gravitational acceleration of the extraterrestrial body must be great enough to drive the ejected material back toward the surface. # The velocity ...

Tsiolkovskiy (crater)
Tsiolkovskiy is a large lunar impact crater that is located on the far side of the Moon. Named for Russian scientist Konstantin Tsiolkovsky, it lies in the southern hemisphere, to the west of the large crater Gagarin, and northwest of Milne. Just to the south is Waterman, with Neujmin to the south-southwest. The crater protrudes into the neighbouring Fermi, an older crater of comparable size that does not have a lava-flooded floor. Characteristics Tsiolkovskiy is one of the most prominent features on the far side of the Moon. It possesses high, terraced inner walls and a well-formed central peak, which rises over 3200 m above the floor of the crater. The floor is unusual for a crater on the far side, as it is covered by the dark-hued mare that is characteristic of the maria found on the near side. The distribution of the mare material is not symmetrical across the floor, but is instead more heavily concentrated to the east and south. There is also a protruding bay of darker ...
