Crater on the Moon From Wikipedia, the free encyclopedia
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.
Coordinates | 20.23°N 30.83°E |
---|---|
Diameter | 100 m[1] |
Eponym | Nicholas Vanserg (pen name of Hugh McKinstry) |
To the northwest is Shakespeare and to the northeast are Cochise and Geology Station 8 at the base of the Sculptured Hills. To the south is Sherlock, and to the southwest are the Apollo 17 landing site and the large crater Camelot.
The crater was named by the astronauts after Harvard University geology professor Hugh McKinstry, who, according to their explanation, sometimes wrote satire under the pseudonym "Nicholas Van Serg".[2] In fact, McKinstry's pseudonym was Nicholas Vanserg.[3][4]
Songwriter, humorist and academic Tom Lehrer, who attended and taught at Harvard, suggested that McKinstry's pseudonym was inspired by the name of the Vanserg Building at Harvard, which is an acronym of its original tenants: Veterans Administration, Naval Science, Electronic Research, and Graduate dining hall. Since it was a temporary building, it never got a "real" name. (This wooden building still exists.)[5] A slightly different list of tenants reported is "Veterans Administration, Naval Science, Electronic Research, and Graduate School".[6][7]
The following samples were collected from Van Serg crater (Station 9), as listed in Table 7-I of the Apollo 17 Preliminary Science Report.[8] The "Rock Type" is from the table, and the "Lithology" is from the Lunar Sample Compendium of the Lunar and Planetary Institute or NASA's Lunar Sample Catalog.
