Hill 305 (lunar Mountain)
Hill 305 is a feature on Earth's Moon, a mountain in the Hadley–Apennine region. Astronauts David Scott and James Irwin landed the Lunar Module ''Falcon'' about 21 km southeast of it in 1971, on the Apollo 15 mission, but they did not visit it. They could see it on the northwestern horizon from nearly everywhere they went. The peak rises approximately 1300 meters above the surrounding plain, known as Palus Putredinis, and part of Hadley Rille curves along its southern margin. The astronauts named the feature, although it is somewhat unclear why. David Scott stated that it was probably "305 meters above something, because that's the normal way the Army designates a hill." But Eric Jones states "a more likely explanation is that the name refers to the azimuth of the summit as seen from the landing site which is, indeed, about 305 degrees (east of north)." The name is informal and not recognized by the IAU The International Astronomical Union (IAU; french: link=ye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

List Of Mountains On The Moon
Mountains on the Moon have heights defined relative to various vertical datums. In the 1960s, the U.S. Army Mapping Service used elevation relative to 1,737,988 meters from the center of the Moon. In the 1970s, the U.S. Defense Mapping Agency used 1,730,000 meters. The '' Clementine'' topographic data published in the 1990s uses 1,737,400 meters. This table is not comprehensive, and does not list the highest places on the Moon. ''Clementine'' data show a range of about 18,100 meters from lowest to highest point on the Moon. The highest point, located on the far side of the Moon, is approximately 6,500 meters higher than Mons Huygens (usually listed as the tallest mountain). Mountains These are isolated mountains or massifs.

Hadley–Apennine
Hadley–Apennine is a region on the near side of Earth's Moon that served as the landing site for the American Apollo 15 mission, the fourth manned landing on the Moon and the first of the " J-missions", in July 1971. The site is located on the eastern edge of Mare Imbrium on a lava plain known as Palus Putredinis. Hadley–Apennine is bordered by the Montes Apenninus (often referred to as "Apennine Front"), a mountain range, and Hadley Rille, a meandering channel, on the east and west, respectively. Data obtained from the composition of soil samples collected on Apollo 15 show that most (about 90%) of the samples from the Apennine Front are brown-glass breccias, and approximately 60–70% obtained from the mare surface are basalt. Although the basalts seem to vary in their texture, their ages appear to be approximately the same. Most of the samples obtained on the Apennine Front are KREEP (potassium, rare-earth elements, phosphorus) materials, anorthosites, recrystallized nori ...

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 Australia). The Moon is a planetary-mass object with a differentiated rocky body, making it a satellite planet under the geophysical definitions of the term and larger than all known dwarf planets of the Solar System. It lacks any significant atmosphere, hydrosphere, or magnetic field. Its surface gravity is about one-sixth of Earth's at , with Jupiter's moon Io being the only satellite in the Solar System known to have a higher surface gravity and density. The Moon orbits Earth at an average distance of , or about 30 times Earth's diameter. Its gravitational influence is the main driver of Earth's tides and very slowly lengthens Earth's day. The Moon's orbit around Earth has a sidereal period of 27.3 days. During each synodic period ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hill 305 AS15-82-11066
A hill is a landform that extends above the surrounding terrain. It often has a distinct summit. Terminology The distinction between a hill and a mountain is unclear and largely subjective, but a hill is universally considered to be not as tall, or as steep as a mountain. Geographers historically regarded mountains as hills greater than above sea level, which formed the basis of the plot of the 1995 film ''The Englishman who Went up a Hill but Came down a Mountain''. In contrast, hillwalkers have tended to regard mountains as peaks above sea level. The '' Oxford English Dictionary'' also suggests a limit of and Whittow states "Some authorities regard eminences above as mountains, those below being referred to as hills." Today, a mountain is usually defined in the UK and Ireland as any summit at least high, while the official UK government's definition of a mountain is a summit of or higher. Some definitions include a topographical prominence requirement, typically ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
David Scott
David Randolph Scott (born June 6, 1932) is an American retired test pilot and NASA astronaut who was the seventh person to walk on the Moon. Selected as part of the third group of astronauts in 1963, Scott flew to space three times and commanded Apollo 15, the fourth lunar landing; he is one of four surviving Moon walkers and the last surviving crew member of Apollo15. Before becoming an astronaut, Scott graduated from the United States Military Academy at West Point and joined the Air Force. After serving as a fighter pilot in Europe, he graduated from the Air Force Experimental Test Pilot School (Class 62C) and the Aerospace Research Pilot School (Class IV). Scott retired from the Air Force in 1975 with the rank of colonel, and more than 5,600 hours of logged flying time. As an astronaut, Scott made his first flight into space as a pilot of the Gemini 8 mission, along with Neil Armstrong, in March 1966, spending just under eleven hours in low Earth orbit. H ...

James Irwin
James Benson Irwin (March 17, 1930 – August 8, 1991) was an American astronaut, aeronautical engineer, test pilot, and a United States Air Force pilot. He served as Apollo Lunar Module pilot for Apollo 15, the fourth human lunar landing. He was the eighth person to walk on the Moon and the first, and youngest, of those astronauts to die. Early life and education Irwin was born March 17, 1930, in Pittsburgh, Pennsylvania, of Scottish and Irish descent, to parents James William Irwin (1896–1979), a U.S. Army World War I veteran, and Elsa Mathilda Irwin (; 1899–1993). Irwin's grandparents emigrated to the U.S. from Altmore Parish at Pomeroy in County Tyrone, Ireland (now Northern Ireland) around 1859. At about the age of 12, he informed his mother about his desire to go to the Moon, letting her know that he might be the first person to do so (he ended up being the eighth). He graduated from East High School in Salt Lake City, Utah in 1947. He received a Bachelor of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apollo Lunar Module
The Apollo Lunar Module (LM ), originally designated the Lunar Excursion Module (LEM), was the lunar lander spacecraft that was flown between lunar orbit and the Moon's surface during the United States' Apollo program. It was the first crewed spacecraft to operate exclusively in the airless vacuum of space, and remains the only crewed vehicle to land anywhere beyond Earth. Structurally and aerodynamically incapable of flight through Earth's atmosphere, the two-stage lunar module was ferried to lunar orbit attached to the Apollo command and service module (CSM), about twice its mass. Its crew of two flew the complete lunar module from lunar orbit to the Moon's surface. During takeoff, the spent descent stage was used as a launch pad for the ascent stage which then flew back to the command module, after which it was also discarded. Overseen by Grumman, the LM's development was plagued with problems that delayed its first uncrewed flight by about ten months and its first crewed ...

Palus Putredinis
Palus Putredinis (Latin ''palūs pūtrēdinis'' "Marsh of Decay") is a small lunar mare in the basin of Mare Imbrium. It stretches from the crater Archimedes southeast toward the rugged Montes Apenninus range located on the southeastern edge of Mare Imbrium. This region is a nearly level, lava-flooded plain bounded by the crater Autolycus and nearby highlands to the northeast and the foothills of the Montes Archimedes to the southwest. The selenographic coordinates are 27.4° N, 0.0° E, and it lies within a diameter of 180 km. In the southern part of this area is a rille system designated Rimae Archimedes. To the south is a prominent linear rille named Rima Bradley, and to the east is the Rima Hadley, which served as the landing site for Apollo 15, and the Rimae Fresnel. Just to the northwest of the Palus Putredinis midpoint is the nearly submerged crater Spurr. Luna 2 crashed in this area on September 13, 1959.. The basalts in this mare have been interpreted as rich i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Bennett Hill (lunar Mountain)
Bennett Hill is a feature on Earth's Moon, a mountain in the Hadley–Apennine region. Astronauts David Scott and James Irwin landed the Lunar Module ''Falcon'' about 27 km east of it in 1971, on the Apollo 15 mission, but they did not visit it. They could see it on the western horizon from nearly everywhere they went. The peak rises approximately 900 meters above the surrounding plain, known as Palus Putredinis. The astronauts named the feature after NASA trajectory designer Floyd Bennett. The name is informal and not recognized by the IAU, but the name is used in the scientific literature, such as the ''Apollo 15 Preliminary Science Report''. (NASA SP-289), 1972. See also * |
