Steno-Apollo 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. The astronauts referred to it simply as Steno during the mission. The north rim of Steno is Geology Station 1 of the mission.
To the south of Steno is Emory, to the northwest are Trident and Powell, and to the northeast is Sherlock.
The crater was named by the astronauts after the Danish geologist Nicolas Steno. [2]
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.
Littrow is a lunar impact crater that is located in the northeastern part of the Moon's near side, on the east edge of Mare Serenitatis. Its diameter is 29 km. The crater is named after Bohemian astronomer Joseph Johann von Littrow (1781–1840). Some distance to the northeast is the prominent crater Römer, while to the south is Vitruvius.
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.
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.
Van Serg 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 3. Van Serg was designated Geology Station 9.
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.
Shakespeare 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 did not visit it, but in fact drove around it during EVA 3.
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.
Mackin is a feature on Earth's Moon, a crater in Taurus–Littrow valley. Astronauts Eugene Cernan and Harrison Schmitt landed north of it in 1972, on the Apollo 17 mission, but did not visit it.
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.
Hess-Apollo is a feature on Earth's Moon, a crater in Taurus–Littrow valley. Astronauts Eugene Cernan and Harrison Schmitt landed north of it in 1972, on the Apollo 17 mission, but did not visit it. The astronauts referred to it simply as Hess during the mission.
Emory is a feature on Earth's Moon, a crater in Taurus–Littrow valley. Astronauts Eugene Cernan and Harrison Schmitt landed north of it in 1972, on the Apollo 17 mission, but did not visit it.
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.
Powell is a feature on Earth's Moon, a crater in Taurus–Littrow valley. Astronauts Eugene Cernan and Harrison Schmitt landed less than 1 km northeast of it in 1972, on the Apollo 17 mission, but they did not visit it.
Bowen-Apollo is a feature on Earth's Moon, a crater in Taurus-Littrow valley, located at the foot of the Sculptured Hills. Astronauts Eugene Cernan and Harrison Schmitt landed to the southwest of it in 1972, on the Apollo 17 mission. They referred to it simply as Bowen during the mission. It is located just east of Geology Station 8.
Henry is a feature on Earth's Moon, a crater in Taurus–Littrow valley, located at the foot of the Sculptured Hills. Astronauts Eugene Cernan and Harrison Schmitt landed to the southwest of it in 1972, on the Apollo 17 mission.
