In addition, the newly collected data derived from the GRAIL mission helps astronomers redefine the late heavy bombardment--a proposed episode that occurred about 4 billion years ago, during which a heavy shower of projectiles pelted the bodies of the inner Solar System, including Earth and its beloved Moon, creating heavy lunar cratering in the process. The concept of the late heavy bombardment is primarily based on the ages of massive near-side craters that are either within, or adjacent to, dark, lava-flooded basins (lunar maria), that are named Oceanus Procellarum and Mare Imbrium. However, the composition of the material existing on and below the surface of the lunar near-side indicates that the temperatures beneath this area are not representative of Earth's Moon as a whole at the time of the late heavy bombardment. The difference in the temperature profiles may have caused scientists to overestimate the amount of crater-excavating projectiles that characterized the late heavy bombardment. New studies by GRAIL scientists indicate that the size distribution of impact craters on the lunar far-side is a more accurate reflection of the crater-forming history of the inner Solar System than those pock-marking the near-side. For those craters smaller than 30 kilometers in diameter, he discovered impacts both increased and decreased porosity in the upper layer of the lunar crust. To Find Nourishment. It is a really good and interesting exercise to find out what it is that nourishes you. When you feel that you're in your element, then you are in your Moon, your ' emotion' body. The Moon represents the past and stores all our memories thus creating a foundation. The Sun symbolises the mind and it's from our own mind that we can view the past. In so doing we can let go of any shaky or insecure structures in order to establish a firmer sense of self. It is only from this that our Sun can begin to shine until we acknowledge this it will be a dim light looking for recognition. Remember however that it is the Moon that holds our experience and a lot of creativity. Coming from our emotions, feeling and need for contact with others (Moon) will always keep us vulnerable and dependent on others' opinions of us.From the light of the Sun and the establishment of our own foundation (as opposed to that of our childhood) then we can bring out the qualities, playfulness and creativity that our Moon has kept in store for us. As the physical Sun and Moon need each other, likewise we to need to work consciously with our own Moon and Sun and you can only do this by knowing your Astrological Birth Chart!
