Daedalus (crater)
Daedalus is a prominent crater located near the center of the far side of the Moon. The inner wall is terraced, and there is a cluster of central peaks on the relatively flat floor. Because of its location (shielded from radio emissions from the Earth), it has been proposed as the site of a future giant radio telescope, which would be scooped out of the crater itself, much like the Arecibo radio telescope, but on a vastly larger scale. The crater is named after Daedalus of Greek myth. It is pictured in famous photographs taken by the Apollo 11 astronauts. In contemporary sources it was called ''Crater 308'' (this was a temporary IAU designation that preceded the establishment of far-side lunar nomenclature). Nearby craters of note include Icarus In Greek mythology, Icarus (; , ) was the son of the master craftsman Daedalus, the architect of the labyrinth of Crete. After Theseus, king of Athens and enemy of King Minos, escaped from the labyrinth, Minos suspected that I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apollo 11
Apollo 11 was a spaceflight conducted from July 16 to 24, 1969, by the United States and launched by NASA. It marked the first time that humans Moon landing, landed on the Moon. Commander Neil Armstrong and Lunar Module pilot Buzz Aldrin landed the Lunar Module Eagle, Lunar Module ''Eagle'' on July 20, 1969, at 20:17 Coordinated Universal Time, UTC, and Armstrong became the first person to step onto the Moon's surface six hours and 39 minutes later, on July 21 at 02:56 UTC. Aldrin joined him 19 minutes later, and they spent about two and a quarter hours together exploring the site they had named Tranquility Base upon landing. Armstrong and Aldrin collected of lunar material to bring back to Earth as pilot Michael Collins (astronaut), Michael Collins flew the Command Module Columbia, Command Module ''Columbia'' in lunar orbit, and were on the Moon's surface for 21 hours, 36 minutes, before lifting off to rejoin ''Columbia''. Apollo 11 was launched by a Saturn V rocket from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Icarus (crater)
Icarus is a Lunar craters, lunar impact crater that lies on the Moon's Far side (Moon), far side. It is located to the west of the huge walled plain Korolev (lunar crater), Korolev, and less than two crater diameters to the east of the crater Daedalus (crater), Daedalus. To the south of Icarus is the smaller Amici (crater), Amici. Icarus has a worn rim and a relatively wide inner wall. A small crater lies across the southern rim, and the side bulges outward slightly along the southwestern face. There is a disproportionately tall central peak located near the crater midpoint. This rise is unusual in that it is taller than the outer rim; most peaks are only about half the crater depth. The remainder of the floor is relatively flat in the eastern half and slightly more irregular to the west. Icarus was named by the Apollo 15 crew. Composer Ralph Towner made a tune called Icarus which was released in an album of the Paul Winter consort. One member of the consort was cellist David D ...

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 it was moved in late 2003 to a dedicated domain.

United States Geological Survey
The United States Geological Survey (USGS), founded as the Geological Survey, is an agency of the U.S. Department of the Interior whose work spans the disciplines of biology, geography, geology, and hydrology. The agency was founded on March 3, 1879, to study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The agency also makes maps of planets and moons, based on data from U.S. space probes. The sole scientific agency of the U.S. Department of the Interior, USGS is a fact-finding research organization with no regulatory responsibility. It is headquartered in Reston, Virginia, with major offices near Lakewood, Colorado; at the Denver Federal Center; and in NASA Research Park in California. In 2009, it employed about 8,670 people. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on its hundredth anniversary, was "Earth Science in the Pub ...

Lunar Crater Radio Telescope
__NOTOC__ The Lunar Crater Radio Telescope (LCRT) is a proposal by the NASA Institute for Advanced Concepts (NIAC) to create an ultra-long-wavelength (that is, wavelengths greater than 10 m, corresponding to frequencies below 30 MHz) radio telescope inside a lunar crater on the far side of the Moon. The reason for building the LCRT on the far side of the Moon would be to avoid interference faced by radio telescopes on the Earth's surface. The Moon would block many sources of radio interference originating on Earth, and would avoid the problems that come from Earth's ionosphere at long radio wavelengths. If completed, the telescope would have a structural diameter of 1.3 km, and the reflector would be 350m in diameter. Robotic lift wires and an anchoring system would enable origami deployment of the parabolic reflector. History A previous proposal put the reflector size at 1 km diameter. In 2021, the LCRT project went into phase II of development in the NIAC ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lipskiy (crater)
Lipskiy is a lunar impact crater on the far side of the Moon. It lies just to the south of the lunar equator, and is the closest named crater to the antipode of the Earth zenith point by 70 kilometers. That is, it lies in the region of the Moon that on average is the most distant from the Earth. Lipskiy is located less than one crater diameter to the north of the prominent crater Daedalus In Greek mythology, Daedalus (, ; Greek language, Greek: Δαίδαλος; Latin language, Latin: ''Daedalus''; Etruscan language, Etruscan: ''Taitale'') was a skillful architect and craftsman, seen as a symbol of wisdom, knowledge and power. H .... To the northeast is Krasovskiy. The crater has been heavily damaged and disrupted by subsequent impacts, leaving a formation that is scarcely recognizable as a crater. The rim and the interior are very irregular, and are overlain by several smaller impacts. The most notable of these are Lipskiy V along the northwestern edge and Lipskiy S is l ...

Racah (crater)
Racah is a lunar impact crater on the far side of the Moon. It lies almost due south of the larger crater Daedalus, and lies across lunar longitude 180°W, i.e. the longitude that is diametrically opposite to the Earth. To the west-southwest of Racah is the crater Aitken, and to the southeast lies De Vries De Vries is one of the most common Netherlands, Dutch surnames. It indicates a geographical origin: "Vriesland" is an old spelling of the Netherlands, Dutch province of Friesland (Frisia). Hence, "de Vries" means "the Frisian". The name has been m .... The rim of this crater is eroded and is not quite circular, having a prominent outward bulge along the west-northwest side. The edge is somewhat damaged along the southern rim, but no significant craters lie along the side. The interior floor is uneven in places with some small impacts. This feature is named after the Israeli physicist Giulio Racah. Satellite craters By convention these features are identified on lunar map ...
