South Ray crater is a small crater in the Descartes Highlands of the Moon photographed from the lunar surface by the astronauts of Apollo 16. The name of the crater was formally adopted by the IAU in 1973. [1]
The Apollo 16 Lunar Module (LM) Orion landed between North Ray and South Ray craters on April 21, 1972. The astronauts John Young and Charles Duke explored the area between the craters over the course of three EVAs using a Lunar Roving Vehicle, or rover. They came closest to South Ray on EVA 2, at station 4 (Cinco crater), about 3.9 km south of the landing site. Duke photographed South Ray from there with a 500-mm lens.
South Ray crater is approximately 700 m in diameter and approximately 120 m deep, [3] with a bright system of rays of ejecta. The astronauts observed that the ejecta of South Ray was very bouldery, and reported that it would have been difficult or impossible to drive there on their rover. [4]
South Ray cuts into the Cayley Formation of Imbrian age. [5] The crater itself is much younger (Copernican).
Apollo 16 was the tenth crewed mission in the United States Apollo space program, administered by NASA, and the fifth and penultimate to land on the Moon. It was the second of Apollo's "J missions", with an extended stay on the lunar surface, a focus on science, and the use of the Lunar Roving Vehicle (LRV). The landing and exploration were in the Descartes Highlands, a site chosen because some scientists expected it to be an area formed by volcanic action, though this proved not to be the case.
Apollo 17 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 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 biological experiment containing five mice that was carried in the command module.
Lunar Sample 61016, better known as "Big Muley", is a lunar sample discovered and collected on the Apollo 16 mission in 1972 in the Descartes Highlands, on the rim of Plum crater, near Flag crater. It is the largest sample returned from the Moon as part of the Apollo program. The rock, an 11.7 kg (26 lb) breccia consisting mainly of shocked anorthosite attached to a fragment of troctolitic "melt rock", is named after Bill Muehlberger, the Apollo 16 field geology team leader.
Shorty is a feature on Earth's Moon, an impact crater in the Taurus–Littrow valley. Astronauts Eugene Cernan and Harrison Schmitt visited it in 1972, on the Apollo 17 mission. It is the location of the famous "orange soil", which geologists believe to be small bits of rapidly-cooled molten rock ejected in a fire fountain. It is about 110 meters in diameter and up to 14 m (15 yd) deep.
Shorty Crater is about 14 m deep. Based on our investigations at the site and later examination of photographs, the impact that formed it penetrated, in order, regolith on the avalanche deposit, the avalanche deposit, regolith on a basalt flow, a basalt flow overlying and protecting the orange and black glass layers, the orange and black glass layers, regolith on a second basalt flow, and, finally, the upper portion of that second flow. Orange and black glass clods and basalt boulders are spread throughout the ejecta blanket surrounding Shorty.
North Ray crater is a small crater in the Descartes Highlands of the Moon visited by the astronauts of Apollo 16. The name of the crater was formally adopted by the IAU in 1973. It is the largest crater sampled by astronauts during the Apollo program.
Palmetto crater is a small crater in the Descartes Highlands of the Moon visited by the astronauts of Apollo 16. The name of the crater was formally adopted by the IAU in 1973.
Camelot is a feature on Earth's Moon, a crater in Taurus-Littrow valley. Astronauts Eugene Cernan and Harrison Schmitt visited it in 1972, on the Apollo 17 mission, during EVA 2. Geology Station 5 was along the south rim of Camelot.
Sherlock is a feature on Earth's Moon, a crater in Taurus–Littrow valley. Astronauts Eugene Cernan and Harrison Schmitt drove their rover to the north of it in 1972, on the Apollo 17 mission. They photographed the rim, as shown below.
Nansen-Apollo is a feature on Earth's Moon, a crater in Taurus-Littrow valley, at the base of the South Massif. Astronauts Eugene Cernan and Harrison Schmitt visited it in 1972, on the Apollo 17 mission. The astronauts referred to it simply as Nansen during the mission. Geology Station 2 of the mission was located at Nansen. Nansen is located in the 'light mantle' which is almost certainly an avalanche deposit from the South Massif.
Lara is a feature on Earth's Moon, a crater in Taurus-Littrow valley. Astronauts Eugene Cernan and Harrison Schmitt visited it in 1972, on the Apollo 17 mission, during EVA 2. Geology Station 3 of the mission is located on the northeast rim of Lara.
Cochise is a feature on Earth's Moon, a crater in Taurus-Littrow valley. Astronauts Eugene Cernan and Harrison Schmitt landed southwest of it in 1972, on the Apollo 17 mission. They drove along its rim in the rover during EVA 3, but did not stop.
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.
Spur is a feature on Earth's Moon, a crater in the Hadley–Apennine region. Astronauts David Scott and James Irwin visited it in 1971, on the Apollo 15 mission, during EVA 2. Spur was designated Geology Station 7.
Dune is a feature on Earth's Moon, a crater in the Hadley–Apennine region. Astronauts David Scott and James Irwin visited the south rim of it in 1971, on the Apollo 15 mission, during EVA 2. The south rim of Dune was designated Geology Station 4 of the mission.
Flag crater is a small crater in the Descartes Highlands of the Moon visited by the astronauts of Apollo 16. The name of the crater was formally adopted by the IAU in 1973. Geology Station 1 is adjacent to Flag, at the much smaller Plum crater.
Spook crater is a small crater in the Descartes Highlands of the Moon visited by the astronauts of Apollo 16. The name of the crater was formally adopted by the IAU in 1973. Geology Station 2 is adjacent to Spook, between it and the smaller, younger crater called Buster to the north of it.
Elbow is a feature on Earth's Moon, a crater in the Hadley–Apennine region. Astronauts David Scott and James Irwin visited the east rim of it in 1971, on the Apollo 15 mission, during EVA 1. The east rim of Elbow was designated Geology Station 1 of the mission. Geology Station 2 was to the southwest of the crater, up the slope of Mons Hadley Delta.
St. George is a feature on Earth's Moon, a crater in the Hadley–Apennine region. Astronauts David Scott and James Irwin drove their rover onto what was suspected to be its ejecta blanket in 1971, on the Apollo 15 mission, during EVA 1. They collected samples to the northeast of the crater, at Geology Station 2 of the mission.
Cinco is a small crater in the Descartes Highlands of the Moon visited by the astronauts of Apollo 16. The crater is one of a group of five (hence the name, Spanish for five) craters that were collectively called the Cinco craters during the Apollo 16 mission. The craters were designated a, b, c, d, and e, and the largest (a) was officially named Cinco after the mission in 1973 by the IAU.
Cone crater is a small crater in the Fra Mauro highlands, north of Fra Mauro crater, on the Moon. The name of the crater was formally adopted by the IAU in 1973.
