Description

Mare Cognitum; “the sea that has become known”, with a diameter of 376 km (10.0 S 23.1 W), is located in a basin that sits within the proposed second ring of the Procellarum basin. The mountain range Montes Riphaeus to the northwest of the region may represent part of the rim-crest of a large buried crater, containing the mare. It's very strange, to see no continuing rim of the large Riphaeus crater on chart SLC E5 (System of Lunar Craters, 1966). Don Davis made interesting paintings of the violent Riphaeus event (the creation of the large impact crater) for Carl Sagan's book COSMOS.

Description: Wikipedia

Mare Cognitum

The space age

A number of spaceflight missions visited this region: Apollo 12 landed close to Surveyor 3, and Apollo 14 landed on the hills at the edge of the Fra Mauro crater. Mare Cognitum is also the location where Ranger 7 and the SIVB stage of Apollo 14 crash-landed.

Ranger 7 in the eastern part of Mare Cognitum

- The impact-craterlet of Ranger 7 is described and depicted in APOLLO OVER THE MOON (Craters, Part 2), Figure 122.
- The two hillocks Bonpland Gamma and Bonpland Omega (north of Ranger 7's impact site) are described and depicted in Chapter 4: The Maria (Part 2), Figure 69.

Apollo 14's impacted SIVB stage in the western part of Mare Cognitum

- The artificial craterlet and surrounding ejectablanket of Apollo 14's impacted SIVB stage is described and depicted in NASA SP-362, APOLLO OVER THE MOON; A VIEW FROM ORBIT, Chapter 5: Craters (Part 2), Figures 120 and 121.
- On the LRO's ACT-REACT Quick Map, the impact craterlet of Apollo 14's SIVB stage is detectable at LON: -26.032, LAT: -8.18 (0.5 M/PIX).- DannyCaes Jul 3, 2011
- The dark ejectablanket of Apollo 14's impacted SIVB stage is also seen on Lunar Topographic Ortophotomap 76-D1 (8°10' South/ 333°57')(26°03' West).
- On orbital image AS16-M-2518, which is included in the book FULL MOON by Michael Light and Andrew Chaikin (Plate 25), is the dark ejectablanket of Apollo 14's impacted SIVB stage also detectable! You need a good magnifying glass and the exact location of the ejectablanket, via LTO map 76-D1. Believe it or not, Danny Caes detected the ejectablanket on the printed version of that photograph in FULL MOON!

Nomenclature

  • Mare Cognitum: "Sea that has become known", thanks to the Ranger VII impact site.
  • Name proposed by Gerard P. Kuiper who was a Ranger PI (see also E.A.Whitaker's Mapping and Naming the Moon, page 174: "Kuiper suggested a choice between Mare Exploratum or Mare Cognitum. After considerable discussion, the second of these (the Known Sea, or The Sea That Has Become Known) received the vote").
  • In the western part of Mare Cognitum is a wrinkle ridge which was once called the Jekaterinburg Damm by Johann Nepomuk Krieger and Rudolf Konig.
  • Another interesting fact is the close proximity of Apollo 14's SIVB impact area near Krieger's Jekaterinburg Damm and the bowl-shaped crater Euclides D.
