Additional Information

  • 1970, Sept.: Luna 16 - first automated sample return, from Mare Fecunditatis
  • Mare area of 220,000 km^2 according to measurements by Jim Whitford-Stark.


  • Called Mare Langrenianum by the father of selenography Michel Florent Van Langren (aka Langrenus).
  • Called Mare Caspium by Johann Hewelcke (aka Hevelius).
  • Called Mare Fecunditatis (or Mare Foecunditatis) by Giovanni Baptista Riccioli.
  • The IAU feature name (Mare Fecunditatis) means "Sea of Fecundity" (or Fertility / Fruitfulness).
  • The impact basin is named after the mare.
  • The craters Taruntius G (Anville), Taruntius H, Taruntius K, and Taruntius P (all of them in the north-northwestern part of Mare Fecunditatis) were frequently photographed during several missions of the Apollo program. All four craters together look like some sort of "Constellation", or rather a "Constellation of Four" (thus nicknamed by Danny Caes, who's investigating all orbital Apollo photographs of these four craters, see page Anville).
