ИСТИНА

New data on the gravitational field of the Moon were obtained from two Grail spacecrafts. The spacecrafts were launched on September 10, 2011 and received the names of Ebb and Flow. The probes flew on the same orbit, one after the other at a height of 55 km above the lunar surface. The distance between the spacecrafts was recorded with micron accuracy and varied depending on the magnitude of the gravitational field when spacecrafts were passing over the visible morphological objects, which included mountains, craters, and also massive objects hidden under the surface of the Moon. According to the GRAIL mission data, there has been made a unique map of the Moon's gravitational field.
