GRAIL (Ebb and Flow)
node
Two spacecraft flying in formation mapped the Moon’s gravity field to a precision no other body has. Orbiter, operated by NASA of United States. Robotic. This mission holds no surface position: it did not reach the surface at a published coordinate, and Atlas draws no mark for it.
A node is not a place. Drawing it on a map would assert something about the world that no stored fact supports.
