One final important point to make about working with the Moon, is that it helps to realise that all things have the need for both generating and clearing. This means that both aspects of the lunar cycle can be used to your advantage for any particular issue or project. For example, if you are looking at having a huge clean-up at home, you could plan and design everything, including any furniture/room arrangement changes, during the waxing time. This is your time for creating new looks and new ways to live. You could then go on to do the cleaning up work during the Waning period. The perfect time to let go of the old, so that the new designs can take their place. GRAIL has also generated new maps showing lunar crustal thickness. These maps have managed to uncover still more large impact basins on the near-side hemisphere of Earth's Moon--revealing that there are fewer such basins on the far-side, which is the side that is always turned away from Earth. This observation begs the question: How could this be if both hemispheres were on the receiving end of the same number of crashing, impacting, crater-excavating projectiles? According to GRAIL data, the answer to this riddle is that most of the volcanic eruptions on Earth's Moon occurred on its near-side hemisphere. During Cassini's close flyby of Enceladus on October 28, 2015, it detected molecular hydrogen as the spacecraft zipped through the plume of ice grains and gas spraying out from cracks slashing though the icy crust of the moon-world. Earlier flybys provided hints that a global subsurface ocean did, indeed, exist, sloshing around above a rocky core. Molecular hydrogen in the plumes could indicate hydrothermal processes, which could play the important role of providing the chemical energy so necessary to support life as we know it. In order to hunt for hydrogen specifically originating on Enceladus, the spacecraft dived particularly close to the strange slashed surface.
