Einstein (crater)
Einstein is a large lunar impact crater that lies along the western limb of the Moon, which makes it difficult to observe from the Earth. The visibility of this formation is subject to libration effects, but even under the best conditions not much detail can be observed except from lunar orbit. Nearby craters of note include Moseley just to the north, Dalton along the eastern rim, Vasco da Gama just to the southeast, and Bohr to the south-southeast. The formation Vallis Bohr Vallis Bohr is a valley on the Moon stretching due south of the crater Einstein. This wide cleft has a length of about 80 kilometers, and is radial to the Mare Orientale impact basin further to the south. The selenographic coordinates of this fe ... is visible to the south. The outer rim of this walled plain has been strongly obliterated by many smaller impacts. Occupying the center of the interior floor is Einstein A, an impact crater with wiktionary:terrace, terraced inner walls and a central peak. The ...

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 ...

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 ...

2001 Einstein
2001 Einstein ( ''prov. designation'': ) is a bright Hungaria asteroid from the innermost region of the asteroid belt. It was discovered by Swiss astronomer Paul Wild at Zimmerwald Observatory near Bern, Switzerland, on 5 March 1973. The X-type asteroid (Xe) has a rotation period of 5.5 hours and measures approximately in diameter. It is named after physicist Albert Einstein (1879–1955). Orbit and classification ''Einstein'' is a member of the Hungaria family, which form the innermost dense concentration of asteroids in the Solar System. It orbits the Sun in the inner main-belt at a distance of 1.7–2.1 AU once every 2 years and 8 months (982 days). Its orbit has an eccentricity of 0.10 and an inclination of 23 ° with respect to the ecliptic. As no precoveries were taken, the asteroid's observation arc begins with its discovery in 1973.

Simpelius (crater)
Simpelius is an impact crater that lies in the southern part 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 north-northwest of the somewhat larger crater Schomberger, and east-southeast of the prominent Moretus. The most distinctive aspect of this crater is the asymmetry of the inner wall, with the side being nearly twice as wide at the southern end as it is to the north. As a result, the level interior floor is offset to the north of the crater interior. The rim and inner wall are less sharply defined than those of Schomberger or Moretus, having been softened and smoothed by impacts. The rim is uneven, with peaks to the north, west, east, and south-southeast, and low sections in between. There are also a number of small crater pits along the inner ...

Ewen Whitaker
Ewen Adair Whitaker (22 June 1922 – 11 October 2016) was a British-born astronomer who specialized in lunar studies. During World War II he was engaged in quality control for the lead sheathing of hollow cables strung under the English Channel as part of the "Pipe Line Under The Ocean" Project (PLUTO) to supply gasoline to Allied military vehicles in France. After the war, he obtained a position at the Royal Greenwich Observatory working on the UV spectra of stars, but became interested in lunar studies. As a sideline, Whitaker drew and published the first accurate chart of the South Polar area of the Moon in 1954, and served as director of the Lunar Section of the British Astronomical Association. After meeting Dr. Gerard P. Kuiper, Director of Yerkes Observatory in Wisconsin, USA, at an International Astronomical Union meeting in Dublin in 1955, he was invited to join Kuiper's fledgling Lunar Project at Yerkes to work on producing a high-quality photographic atlas of the Moon ...
