Tacchini (crater)
Tacchini is a lunar impact crater on the northwestern edge of the Mare Smythii, near the eastern limb of the Moon. It was named after Italian astronomer Pietro Tacchini. It lies just to the south of the prominent crater Neper, and was designated Neper K before being given its current name by the IAU. To the west-southwest of Tacchini is the crater pair of Schubert and Back. This crater is roughly circular in form, with a rim that is better defined along the eastern side. The northwestern half of the floor is elevated, along the side where ejecta from the younger Neper intrudes into the interior. There is a pair of small craters along the northwestern inner wall.

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 ...

Kalmbach Books
Kalmbach Media (formerly Kalmbach Publishing Co.) is an American publisher of books and magazines, many of them railroad-related, located in Waukesha, Wisconsin. History The company's first publication was ''The Model Railroader'', which began publication in the summer of 1933 with a cover date of January 1934. A press release announcing the magazine appeared in August 1933, but did not receive much interest. In 1940, business was good enough for Kalmbach to launch another magazine about railroads in general with the simple title of ''Trains Magazine''. From its first issue dated November 1940, it grew quickly from an initial circulation of just over 5,000. Kalmbach became exclusively a publisher when it discontinued its printing operations in 1973, opting to contract production from other printers. In 1985, Kalmbach purchased AstroMedia Corporation, adding its four magazines: ''Astronomy'', ''Deep Sky'', the children's science magazine ''Odyssey'' and ''Telescope Making'' ...

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 ...

Schubert (lunar Crater)
Schubert is a lunar impact crater that lies near the eastern limb of the Moon's near side. It is located northwest of the Mare Smythii, and southwest of the prominent crater Neper. Nearly attached to the southern rim is the crater Back. Schubert is a nearly circular crater formation that has not suffered significant erosion from subsequent impacts, and retains a well-defined rim. The interior surface is generally flat, with a few low hills near the center. 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 Schubert. The following craters have been renamed by the IAU. * Schubert B — ''See'' Back (crater). * Schubert Y — ''See'' Nobili (crater). * Schubert Z — ''See'' Jenkins (crater).

Pietro Tacchini
Pietro Tacchini (March 21, 1838 – March 24, 1905) was an Italian astronomer. He was born and raised in Modena, Italy. He studied engineering at the University of Padova. At the age of 21, he was appointed the director of a small observatory in Modena. By 1863 he became the ''Primo Astronomo Aggiunto'', or director of the observatory, at Palermo, Italy. He remained there until 1879, and focused most of his attention on observations of the Sun. In 1865 he founded the specialist physical astronomy journal, ''Memorie della Società degli Spettroscopisti'', and remained the editor until 1905. (This publication later became the ''Memorie della Società Astronomica Italiana'' in 1920.) Tacchini established an observation network with other Italian astronomers to spectroscopically examine the sun at about the same time daily. He likewise organized an observatory in Calcutta to watch the sun when conditions were unfavorable in Italy. In 1874 he led an expedition to Muddapur, India ...

Neper (crater)
Neper is an old lunar impact crater located near the eastern limb of the Moon. Due to its location the crater must be viewed during a suitable libration, and is very foreshortened. The crater lies on the south edge of Mare Marginis, to the east of the crater Jansky. To the northwest across the Mare Marginis is the crater Goddard. The crater inner walls have worn terraces, with low rim edges at the northern and southern extremes. The crater floor is dark and flat, with a central peak and several crater impacts near the west rim. The most notable of these is a small crater near the north-northwestern edge. It is named after the Scottish mathematician, physicist, astronomer and astrologer John Napier. 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 Neper. The following craters have been renamed by the IAU. * Neper G - ''See'' Virchow (crater). * Neper K - ''See'' Tacchini ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
