Henry (Apollo lunar crater) part of the reason is that the IAU recognizes the larger lunar crater Henry. The crater was named by the astronauts after the Portuguese Prince Henry the Navigator. Henry (Apollo lunar crater) 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. Henry is northwest of Shakespeare and Van Serg, and west of Cochise. It is south of Geology Station 6 of the Apollo 17 mission. The crater's name is currently
Tsiolkovskiy (crater) in Mendeleev crater far to the northeast are called Catena Mendeleev, and the row points directly at Tsiolkovsky. For this reason the craters are believed to be secondaries from the Tsiolkovsky impact. This feature was discovered on photographs sent back by the Russian spacecraft Luna 3, and was subsequently imaged by several of the American Lunar Orbiters and then by Apollo astronauts. Apollo 17 Astronaut Harrison "Jack" Schmitt and other scientists (Schmitt was the only trained scientist, a geologist, to walk on the moon) strongly advocated Tsiolkovskiy as the landing site of Apollo 17, using small communications satellites deployed from
