Hoffmeister (crater)
Hoffmeister is a lunar impact crater that is located on the Moon's far side, to the northwest of the huge walled plain Mendeleev. Some distance to the north of Hoffmeister lies the crater Siedentopf, and to the west-northwest is Gavrilov. This is a somewhat eroded crater with Hoffmeister N attached to the southern rim. A small crater with a high albedo Albedo (; ) is the measure of the diffuse reflection of sunlight, 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 ... lies along the common rim between Hoffmeister and this satellite. A small crater also lies along the northwestern rim of Hoffmeister. The interior floor of Hoffmeister is relatively featureless. 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 Hoffmeister. See also * 172 ...

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 ...

Gavrilov (crater)
Gavrilov is a lunar impact crater on the far side of the Moon The Moon is Earth's only natural satellite. It is the fifth largest satellite in the Solar System and the largest and most massive relative to its parent planet, with a diameter about one-quarter that of Earth (comparable to the width of .... It lies to the south of the heavily eroded crater Vernadskiy, and north of Vetchinkin. This is a circular and relatively symmetric crater formation with some erosion of the outer rim. There are some small craterlets in the eastern half of the interior, and a small central rise near the midpoint. 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 Gavrilov.

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 ...

1726 Hoffmeister
1726 Hoffmeister, provisional designation , is a carbonaceous asteroid and namesake of the Hoffmeister family from the central region of the asteroid belt, approximately 23 kilometers in diameter. It was discovered on 24 July 1933, by German astronomer Karl Reinmuth at Heidelberg Observatory in southwest Germany, and named after astronomer Cuno Hoffmeister. Orbit and classification ''Hoffmeister'' is the namesake and lowest-numbered member of the very compact Hoffmeister family (), which, based upon its low albedo, was most likely formed from the breakup of a 50–100 kilometer-sized, carbon-rich parent body within the past several hundred million years. It orbits the Sun in the central main-belt at a distance of 2.7–2.9 AU once every 4 years and 8 months (1,700 days; semi-major axis of 2.79 AU). Its orbit has an eccentricity of 0.04 and an inclination of 3 ° with respect to the ecliptic. It was first identified as at the Yerkes Observatory in 1924, extend ...

Albedo
Albedo (; ) is the measure of the diffuse reflection of sunlight, 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 reflects all incident radiation. Surface albedo is defined as the ratio of Radiosity (radiometry), radiosity ''J''e to the irradiance ''E''e (flux per unit area) received by a surface. The proportion reflected is not only determined by properties of the surface itself, but also by the spectral and angular distribution of solar radiation reaching the Earth's surface. These factors vary with atmospheric composition, geographic location, and time (see position of the Sun). While bi-hemispherical reflectance is calculated for a single angle of incidence (i.e., for a given position of the Sun), albedo is the directional integration of reflectance over all solar angles in a given period. The temporal resolution may range from seconds (as ob ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Siedentopf (crater)
Siedentopf is a worn impact crater on the far side of the Moon. It lies to the east-southeast of the larger crater Vernadskiy. Farther to the south is Hoffmeister. The northwestern section of the crater rim has been damaged, but the remainder of the rim is only moderately worn. The satellite crater Siedentopf Q intrudes into the rim along the southwestern side, and the 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 ... of this impact covers a portion of the interior floor of Siedentopf.

Kilometre
The kilometre ( SI symbol: km; or ), spelt kilometer in American English, is a unit of length in the International System of Units (SI), equal to one thousand metres (kilo- being the SI prefix for ). It is now the measurement unit used for expressing distances between geographical places on land in most of the world; notable exceptions are the United States and the United Kingdom where the statute mile is the unit used. The abbreviations k or K (pronounced ) are commonly used to represent kilometre, but are not recommended by the BIPM. A slang term for the kilometre in the US, UK, and Canadian militaries is ''klick''. Pronunciation There are two common pronunciations for the word. # # The first pronunciation follows a pattern in English whereby metric units are pronounced with the stress on the first syllable (as in kilogram, kilojoule and kilohertz) and the pronunciation of the actual base unit does not change irrespective of the prefix (as in centimetre, millimetre ...

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 the ...
