Description
This IAU name commemorates the February 3, 1966 landing site of Luna 9, the first spacecraft from Earth to successfully soft-land on the Moon and return images from it. In the Lunar Orbiter image shown here, the official IAU coordinates are marked by a white cross on the peak to the right of center, but the actual landing was in a mare area. Many charts place the Luna 9 landing site in the plain immediately to the left of the cross. However NASA SP-241, which may be more definitive, places it to the right, almost touching the left side of the bright crescent. The position shown in SP-241 is approximately 7.19°N, 64.18°W
Although Planitia means "plain" the name is thought to refer, like Statio Tranquillitatis, to the landing site only, a feature of zero size, and not to the surrounding region.

Additional Information
- Luna 9 was the first mission to establish that the lunar surface (at least at that point) could bear the weight of a spacecraft.
- Robert Christy gives the landing site coordinates as 7.13 degrees north, 60.36 degrees west (the latter, giving a location near Reiner Gamma, is almost certainly a typo).
- John Walker gives the landing site coordinates as 7.08 degrees north, 64.37 degrees west (a position on the peak, very close to the cross).
Nomenclature
- Luna 9 landing site ("plain of descent").
- Called Sinus Adlunationis on the Complete Moon Map of 1969 by the Sternberg Astronomy Institute. Research: Danny Caes
