Trident (crater)
Trident is a feature on Earth's Moon, a crater in Taurus-Littrow valley. Astronauts Eugene Cernan and Harrison Schmitt landed about 300 m north of its rim in 1972, on the Apollo 17 mission. They drove along the east rim of Trident during EVA 1 of the mission, in their rover. To the south of Trident is Powell, to the west are Camelot and Horatio, and to the east is Sherlock. The crater was named by the astronauts after a trident A trident is a three- pronged spear. It is used for spear fishing and historically as a polearm.

Trident Crater AS17-P-2750 ASU
A trident is a three-tine (structural), pronged spear. It is used for spear fishing and historically as a polearm. The trident is the weapon of Poseidon, or Neptune (mythology), Neptune, the God of the Sea in classical mythology. The trident may occasionally be held by other marine divinities such as Triton (mythology), Tritons in classical art. Tridents are also depicted in medieval heraldry, sometimes held by a merman-Triton. In Hindu mythology, Hinduism, it is the weapon of Shiva, known as ''trishula'' (Sanskrit for "triple-spear"). Etymology The word "trident" comes from the French language, French word ''trident'', which in turn comes from the Latin language, Latin word ' or ': ''tri'' meaning "three" and ''dentes'' meaning "teeth", referring specifically to the three prongs, or "teeth", of the weapo The Greek language, Greek equivalent is (''tríaina''), from Proto-Greek ''trianja'', meaning "threefold". The Greek term does not imply three of anything specific, and is v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Eugene Cernan
Eugene Andrew Cernan (; March 14, 1934 – January 16, 2017) was an American astronaut, naval aviator, electrical engineer, aeronautical engineer, and fighter pilot. During the Apollo 17 mission, Cernan became the eleventh human being to walk on the Moon. As he re-entered the Apollo Lunar Module after Harrison Schmitt on their third and final lunar excursion, he remains as of 2022, famously: "The last man on the Moon". Before becoming an astronaut, Cernan graduated with a Bachelor of Science degree in electrical engineering from Purdue University and joined the U.S. Navy through the Naval Reserve Officers Training Corps (NROTC). After flight training, he received his naval aviator wings and served as a fighter pilot. In 1963, he received a Master of Science degree in aeronautical engineering from the U.S. Naval Postgraduate School. Achieving the rank of captain, he retired from the Navy in 1976. Cernan traveled into space three times and to the Moon twice: as pilot of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harrison Schmitt
Harrison Hagan Schmitt (born July 3, 1935) is an American geologist, retired NASA astronaut, university professor, former U.S. senator from New Mexico, and the most recent living person—and only person without a background in military aviation—to have walked on the Moon. In December 1972, as one of the crew onboard Apollo 17, Schmitt became the first member of NASA's first scientist-astronaut group to fly in space. As Apollo 17 was the last of the Apollo missions, he also became the twelfth and second-youngest person to set foot on the Moon and the second-to-last person to step off of the Moon (he boarded the Lunar Module shortly before commander Eugene Cernan). Schmitt also remains the only professional scientist to have flown beyond low Earth orbit and to have visited the Moon. He was influential within the community of geologists supporting the Apollo program and, before starting his own preparations for an Apollo mission, had been one of the scientists training those A ...

Apollo 17
Apollo 17 (December 7–19, 1972) was the final mission of NASA's Apollo program, the most recent time humans have set foot on the Moon or traveled beyond low Earth orbit. Commander Gene Cernan and Lunar Module Pilot Harrison Schmitt walked on the Moon, while Command Module Pilot Ronald Evans (astronaut), Ronald Evans orbited above. Schmitt was the only professional geologist to land on the Moon; he was selected in place of Joe Engle, as NASA had been under pressure to send a scientist to the Moon. The mission's heavy emphasis on science meant the inclusion of a number of new experiments, including a Fe, Fi, Fo, Fum, and Phooey, biological experiment containing five mice that was carried in the command module. Mission planners had two primary goals in deciding on the landing site: to sample Lunar highlands, lunar highland material older than that at Mare Imbrium and to investigate the possibility of relatively recent Volcano, volcanic activity. They therefore selected Taurus– ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extra-vehicular Activity
Extravehicular activity (EVA) is any activity done by an astronaut in outer space outside a spacecraft. In the absence of a breathable Earthlike atmosphere, the astronaut is completely reliant on a space suit for environmental support. EVA includes ''spacewalks'' and lunar or planetary surface exploration (commonly known from 1969 to 1972 as ''moonwalks''). In a stand-up EVA (SEVA), an astronaut stands through an open hatch but does not fully leave the spacecraft. EVA has been conducted by the Soviet Union/Russia, the United States, Canada, the European Space Agency and China. On March 18, 1965, Alexei Leonov became the first human to perform a spacewalk, exiting the Voskhod 2 capsule for 12 minutes and 9 seconds. On July 20, 1969, Neil Armstrong became the first human to perform a moonwalk, outside his lunar lander on Apollo 11 for 2 hours and 31 minutes. On the last three Moon missions, astronauts also performed deep-space EVAs on the return to Earth, to retrieve film canis ...

Lunar Roving Vehicle
The Lunar Roving Vehicle (LRV) is a battery-powered four-wheeled rover used on the Moon in the last three missions of the American Apollo program ( 15, 16, and 17) during 1971 and 1972. It is popularly called the Moon buggy, a play on the term '' dune buggy''. Built by Boeing, each LRV has a mass of without payload. It could carry a maximum payload of , including two astronauts, equipment, and lunar samples, and was designed for a top speed of , although it achieved a top speed of on its last mission, Apollo 17. Each LRV was carried to the Moon folded up in the Lunar Module's Quadrant 1 Bay. After being unpacked, each was driven an average of 30 km, without major incident. These three LRVs remain on the Moon. History The concept of a lunar rover predated Apollo, with a 1952–1954 series in ''Collier's Weekly'' magazine by Wernher von Braun and others, "Man Will Conquer Space Soon!" In this, von Braun described a six-week stay on the Moon, featuring 10-ton tractor trai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Powell (crater)
Powell is a feature on Earth's Moon, a crater in Taurus–Littrow valley.
