McDonald (crater)
McDonald is a small lunar impact crater located in the central Mare Imbrium. It was named after American benefactor William Johnson McDonald and Scottish selenographer Thomas Logie MacDonald. This crater is a cup-shaped feature with a circular rim, and has not been significantly eroded. It lies to the southeast of the slightly larger crater Carlini, in an isolated part of the mare. This feature was identified as 'Carlini B' prior to being renamed by the IAU.

Apollo 15
Apollo 15 (July 26August 7, 1971) was the ninth crewed mission in the United States' Apollo program and the fourth to Moon landing, land on the Moon. It was the first List of Apollo missions#Alphabetical mission types, J mission, with a longer stay on the Moon and a greater focus on science than earlier landings. Apollo 15 saw the first use of the Lunar Roving Vehicle. The mission began on July 26 and ended on August 7, with the lunar surface exploration taking place between July 30 and August 2. Apollo Commander, Commander David Scott and Lunar Module Pilot James Irwin landed near Hadley–Apennine#Rima Hadley, Hadley Rille and explored the local area using the rover, allowing them to travel further from the Apollo Lunar Module, lunar module than had been possible on previous missions. They spent 18 hours on the Moon's surface on four extravehicular activities (EVA), and collected of surface material. At the same time, Command Module Pilot Alfred Worden orbited the Moo ...

William Johnson McDonald
William Johnson McDonald (December 21, 1844 – February 8, 1926, though some sources give his date of death as February 6 ) was a Paris, Texas banker who left $850,000 (the bulk of his fortune) to the University of Texas System to endow an astronomical observatory. The bequest was unexpected, and his will was contested, but after prolonged legal disputes the university received the money. At the time, the university had no faculty of astronomy, so in 1932 it formed a collaboration with Otto Struve at the University of Chicago, who supplied astronomers. The McDonald Observatory is named after him, with Otto Struve becoming the first director. McDonald was the eldest of the three sons of Sarah Johnson and Henry Graham McDonald of Paris, Texas. As a young man, he was a private in the Confederate Confederacy or confederate may refer to: States or communities * Confederate state or confederation, a union of sovereign groups or communities * Confederate States of America, a c ...

Mare Imbrium
Mare Imbrium (Latin ''imbrium'', the "Sea of Showers" or "Sea of Rains", "Sea of Tears") is a vast lava plain within the Imbrium Basin on the Moon and is one of the larger craters in the Solar System. The Imbrium Basin formed from the collision of a proto-planet during the Late Heavy Bombardment. Basaltic lava later flooded the giant crater to form the flat volcanic plain seen today. The basin's age has been estimated using uranium–lead dating methods to approximately 3.9 billion years ago, and the diameter of the impactor has been estimated to be 250 ± 25 km. The Moon's maria (plural of mare) have fewer features than other areas of the Moon because molten lava pooled in the craters and formed a relatively smooth surface. Mare Imbrium is not as flat as it was originally thought, because later events have altered its surface. Origin Mare Imbrium formed when a proto-planet from the asteroid belt collided with the moon during the Late Heavy Bombardment. The impact i ...

Carlini (crater)
Carlini is a small lunar impact crater located in the Mare Imbrium. It was named after Italian astronomer Francesco Carlini. The crater is bowl-shaped with a small central floor. It has a higher albedo than the surrounding mare, making it prominent due to its isolated location. To the south is a wrinkle ridge named Dorsum Zirkel, and farther south lies the peak Mons La Hire. 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 Carlini. The following craters have been renamed by the IAU. * Carlini B — ''See'' McDonald (crater) McDonald is a small lunar impact crater located in the central Mare Imbrium.

Lunar Mare
The lunar maria (; singular: mare ) are large, dark, basaltic plains on Earth's Moon, formed by ancient asteroid impacts on the far side on the Moon that triggered volcanic activity on the opposite (near) side. They were dubbed , Latin for 'seas', by early astronomers who mistook them for actual seas. They are less reflective than the "highlands" as a result of their iron-rich composition, and hence appear dark to the naked eye. The maria cover about 16% of the lunar surface, mostly on the side visible from Earth. The few maria on the far side are much smaller, residing mostly in very large craters. The traditional nomenclature for the Moon also includes one (ocean), as well as features with the names ('lake'), ('marsh'), and ('bay'). The last three are smaller than maria, but have the same nature and characteristics. The names of maria refer to sea features (Mare Humorum, Mare Imbrium, Mare Insularum, Mare Nubium, Mare Spumans, Mare Undarum, Mare Vaporum, Oceanus Procellarum ...

International Astronomical Union
The International Astronomical Union (IAU; french: link=yes, Union astronomique internationale, UAI) is a nongovernmental organisation with the objective of advancing astronomy in all aspects, including promoting astronomical research, outreach, education, and development through global cooperation. It was founded in 1919 and is based in Paris, France. The IAU is composed of individual members, who include both professional astronomers and junior scientists, and national members, such as professional associations, national societies, or academic institutions. Individual members are organised into divisions, committees, and working groups centered on particular subdisciplines, subjects, or initiatives. As of 2018, the Union had over 13,700 individual members, spanning 90 countries, and 82 national members. Among the key activities of the IAU is serving as a forum for scientific conferences. It sponsors nine annual symposia and holds a triannual General Assembly that sets policy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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 ...
