With ALL of the recent solar, Venusian and asteroid news, I can finally get around to updating you on the progress of lunar spacecraft Gravity Recovery And Interior Laboratory (GRAIL) A and B. The lunar twins - renamed Ebb and Flow - are in fine shape and have started their 84-day science mission of mapping the gravity of the Moon.
The data collected will be analyzed and transformed into a ground breaking understanding of the Moon's interior. Many questions that have lingered about whether the Moon has a molten core, differences between the near and far sides, and general structure are expected to be answered. This information will help us understand how the Moon formed, whether it could still be geologically active today and provide insight on the interiors of other planets in the solar system.
