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. [1]
On April 21, 1972, the Apollo 16 Lunar Module (LM) Orion landed about 1.5 km south of Palmetto, which is between the prominent North Ray and South Ray craters. The astronauts John Young and Charles Duke explored the area over the course of three EVAs using a Lunar Roving Vehicle, or rover. They drove along the rim of Palmetto on EVA 3, on their way to North Ray, but did not stop. As they drove by, Duke said "There's a good ejecta blanket of half-meter-size boulders around the rim of Palmetto into some of these secondary craters here." [2] On the way back to the lunar module from North Ray, Duke took a sequence of photos of Palmetto while riding on the rover.
The crater was also used as a landmark by Apollo astronauts on previous missions. It was designated landmark DE-1/12, [3] and astronaut Dick Gordon tracked it photographically on revolutions 42 and 44 of the Apollo 12 mission.
Palmetto crater is approximately 760 m in diameter and approximately 130 m deep. [4] The similar-sized crater Gator lies 1 km to the southeast.
Palmetto cuts into the Cayley Formation of Imbrian age. [5]
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.
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.
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.
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.
Victory 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. The astronauts stopped at the south rim of Victory on their way back to the Lunar Module from Shorty crater.
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.
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.
Horatio is a feature on Earth's Moon, a crater in Taurus-Littrow valley. Astronauts Eugene Cernan and Harrison Schmitt drove the Lunar Roving Vehicle along its south rim in 1972, on the Apollo 17 mission, but did not stop.
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.
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.
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.
