Maskelyne (crater)
Maskelyne is a solitary lunar impact crater that lies in the southeast part of the Mare Tranquillitatis. Its diameter is 22 km. It was named after British astronomer Nevil Maskelyne. The outer rim has a somewhat polygonal shape, although it is generally circular. The inner walls are terraced and there is a low central rise at the midpoint of the floor. The landing site of the Apollo 11 expedition is located about 250 kilometers to the west-southwest. To the northeast are Wallach and Aryabhata. To the southeast is the bright Censorinus. To the south are the lunar mountains informally known as Duke Island and Boot Hill. There are sinuous rilles southwest and west of Maskelyne - these were informally named ''Sidewinder'' and ''Diamondback'' by the Apollo 10 crew ''We is down among them ...

Apollo 10
Apollo 10 (May 18–26, 1969) was a human spaceflight, the fourth crewed mission in the United States Apollo program, and the second (after Apollo8) to orbit the Moon. NASA described it as a "dress rehearsal" for the first Moon landing, and designated it an "F"mission, intended to test all spacecraft components and procedures short of actual descent and landing. While astronaut John Young remained in the Command and Service Module (CSM) orbiting the Moon, astronauts Thomas Stafford and Gene Cernan flew the Apollo Lunar Module (LM) to within of the lunar surface, the point at which powered descent for landing would begin on a landing mission, before rejoining Young in the CSM. After orbiting the Moon 31 times, Apollo 10 returned safely to Earth; its success enabled the first crewed landing during Apollo 11 two months later. While NASA had considered attempting the first crewed lunar landing on Apollo 10, mission planners ultimately decided that it would be prudent to have ...

Boot Hill (lunar Mountain)
Boot Hill is a small lunar mountain that is located in Mare Tranquillitatis, about 45 km south of the crater Maskelyne, and about 210 km east of the Apollo 11 landing site. The peak at its north end rises approximately 230 m above the surrounding mare. Unlike many other lunar features named by the Apollo astronauts, the name of the mountain is not formally recognized by the International Astronomical Union. However, Boot Hill and other informal features such as the nearby Duke Island or Mount Marilyn (within Montes Secchi) were significant landmarks used by the astronauts for navigation to the first landing site.

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 ...

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 ...

Rille
Rille (German for 'groove') is typically used to describe any of the long, narrow depressions in the surface of the Moon that resemble channels. The Latin term is ''rima'', plural ''rimae''. Typically, a rille can be several kilometers wide and hundreds of kilometers in length. However, the term has also been used loosely to describe similar structures on a number of planets in the Solar System, including Mars, Venus, and on a number of moons. All bear a structural resemblance to each other. Structures Three types of rille are found on the lunar surface: * Sinuous rilles meander in a curved path like a mature river, and are commonly thought to be the remains of collapsed lava tubes or extinct lava flows. They usually begin at an extinct volcano, then meander and sometimes split as they are followed across the surface. , 195 sinuous rilles have been identified on the Moon. Vallis Schröteri in Oceanus Procellarum is the largest sinuous rille, and Rima Hadley is the only one ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Duke Island (lunar Mountain)
Duke Island is a small lunar mountain that is located in Mare Tranquillitatis, about 64 km southwest of the crater Maskelyne, and about 188 km east of the Apollo 11 landing site.
