Index (crater)
Index is a feature on Earth's Moon, a crater in the Hadley–Apennine region. Astronauts David Scott and James Irwin landed the Lunar Module ''Falcon'' northwest of it in 1971, on the Apollo 15 mission, but they did not visit it. They intended to land closer to Index, but actually landed next to Last crater. Index is the southernmost of a line of four craters which were used by the astronauts as landmarks during descent to the surface. The other three are called ''Luke'', ''Mark'', and ''Matthew'', after three of the four major Gospels of the Bible. They were not allowed to call the crater ''John'' due to the fact that atheist Madalyn Murray O'Hair had sued NASA for astronauts reading from Genesis during Apollo 8.

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] |
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 ...

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 ...

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 ...

Last (crater)
Last is a feature on Earth's Moon, a crater in the Hadley–Apennine region. Astronauts David Scott and James Irwin landed the Lunar Module ''Falcon'' on the northern edge of it in 1971, on the Apollo 15 mission. Last crater is located approximately 2 km east of Hadley Rille and approximately 1 km northwest of Index, the intended landing point. The name of the crater was formally adopted by the IAU 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 ... in 1973.

Gospel
Gospel originally meant the Christian message ("the gospel"), but in the 2nd century it came to be used also for the books in which the message was set out. In this sense a gospel can be defined as a loose-knit, episodic narrative of the words and deeds of Jesus, culminating in his trial and death and concluding with various reports of his post-resurrection appearances. Modern scholars are cautious of relying on the gospels uncritically, but nevertheless, they provide a good idea of the public career of Jesus, and critical study can attempt to distinguish the original ideas of Jesus from those of the later authors. The four canonical gospels were probably written between AD 66 and 110. All four were anonymous (with the modern names added in the 2nd century), almost certainly none were by eyewitnesses, and all are the end-products of long oral and written transmission. Mark was the first to be written, using a variety of sources. The authors of Matthew and Luke both independently ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atheist
Atheism, in the broadest sense, is an absence of belief in the existence of deities. Less broadly, atheism is a rejection of the belief that any deities exist. In an even narrower sense, atheism is specifically the position that there no deities. Atheism is contrasted with theism, which in its most general form is the belief that at least one deity exists. The first individuals to identify themselves as atheists lived in the 18th century during the Age of Enlightenment. The French Revolution, noted for its "unprecedented atheism", witnessed the first significant political movement in history to advocate for the supremacy of human reason.Extract of page 22 In 1967, Albania declared itself the first official atheist cou ...

Madalyn Murray O'Hair
Madalyn Murray O'Hair (née Mays; April 13, 1919 – September 29, 1995) was an American activist supporting atheism and separation of church and state. In 1963 she founded American Atheists and served as its president until 1986, after which her son Jon Garth Murray succeeded her. She created the first issues of ''American Atheist Magazine'' and identified as a " militant feminist". O'Hair is best known for the '' Murray v. Curlett'' lawsuit, which challenged the policy of mandatory prayers and Bible reading in Baltimore public schools, in which she named her first son William J. Murray as plaintiff. Consolidated with ''Abington School District v. Schempp'' (1963), it was heard by the United States Supreme Court, which ruled that officially sanctioned mandatory Bible-reading in American public schools was unconstitutional. The Supreme Court had prohibited officially sponsored prayer in schools in '' Engel v. Vitale'' (1962) on similar grounds. After she founded the American Athe ...

Apollo 8 Genesis Reading
On Christmas Eve, December 24, 1968, the crew of Apollo 8 read from the Book of Genesis as they orbited the Moon. Astronauts Bill Anders, Jim Lovell, and Frank Borman, the first humans to travel to the Moon, recited verses 1 through 10 of the Genesis creation narrative from the King James Bible. Anders read verses 1–4, Lovell verses 5–8, and Borman read verses 9 and 10. Drafting Borman felt that his initial attempts to draft something appropriate sounded too much like an apology for the United States involvement in the Vietnam War, and Joseph Laitin of the Bureau of the Budget (now the Office of Management and Budget) was brought in to assist. Laitin himself had the same problem; his initial drafts centered on the concept of peace on Earth, which felt inappropriate in light of the ongoing war effort, and he began looking through the New Testament to find a good connection between the Christmas season and the biblical accounts of the birth of Jesus. The suggestion to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apollo 8
Apollo 8 (December 21–27, 1968) was the first crewed spacecraft to leave low Earth orbit and the first human spaceflight to reach the Moon. The crew orbited the Moon ten times without landing, and then departed safely back to Earth. These three astronauts—Frank Borman, James Lovell, and William Anders—were the first humans to personally witness and photograph the far side of the Moon and an Earthrise. Apollo 8 launched on December 21, 1968, and was the second crewed spaceflight mission flown in the United States Apollo space program after Apollo7, which stayed in Earth orbit. Apollo8 was the third flight and the first crewed launch of the Saturn V rocket, and was the first human spaceflight from the Kennedy Space Center, located adjacent to Cape Kennedy Air Force Station in Florida. Originally planned as the second crewed Apollo Lunar Module and command module test, to be flown in an elliptical medium Earth orbit in early 1969, the mission profile was changed in ...
