Tracy's Rock
Tracy's Rock, known as Split Rock or the Station 6 Boulder in the scientific literature, is a large boulder on the Moon which was visited by the Apollo 17 crew on December 13, 1972 at their Taurus-Littrow landing site. "Tracy's Rock" is its popular name. Examination Geologist-astronaut Harrison H. Schmitt and mission commander Eugene A. Cernan spent considerable time studying the rock and its vicinity at station 6 during their third Extravehicular Activity (EVA-3). :"Gene stepped to the northeast corner of fragment 1, put his left hand on the dust-covered shelf to support himself, and reached out as far as possible toward the center of the dusted area and swept the bag twice from his right to his left, leaving furrows and, at the lefthand end of each furrow, a small mound of dust where he stopped... A labeled detail from frame AS17-140-21496 shows the sample location, the area on the shelf probably disturbed by his left hand, and the area on the ground between fragment 1 ...

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] |
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] |
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 ...

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] |
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] |
Alan Bean
Alan LaVern Bean (March 15, 1932 – May 26, 2018) was an American naval officer and aviator, aeronautical engineer, test pilot, NASA astronaut and painter; he was the fourth person to walk on the Moon. He was selected to become an astronaut by NASA in 1963 as part of Astronaut Group 3. Before becoming an astronaut, Bean graduated with a Bachelor of Science degree in Aeronautical Engineering from University of Texas at Austin in 1955 and re-joined the U.S. Navy—he served as an enlisted member for a year after his high school graduation. He received his naval aviator wings in 1956 and served as a fighter pilot. In 1960, he graduated from the U.S. Naval Test Pilot School, flew as a test pilot and was The New Nine selection finalist in 1962. He made his first flight into space aboard Apollo 12, the second crewed mission to land on the Moon, at age 37 in November 1969. He made his second and final flight into space on the Skylab 3 mission in 1973, the second crewed missi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geological Features On The Moon
Geology () is a branch of natural science concerned with Earth and other astronomical objects, the features or rocks of which it is composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology, and so is treated as one major aspect of integrated Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface, and the processes that have shaped that structure. It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks. By combining these tools, geologists are able to chronicle the geological history of the Earth as a whole, and also to demonstrate the age of the Earth. Geology provides the primary evidence for plate tectonics, the evolutionary history of life, and the Earth's past climates. Geologists broadly study the properties and processes of Eart ...
