TOKYO (Earth-Life Science Institute PR) — Earth’s Moon has a ‘near side’ that is perpetually Earth-facing and a ‘far side’, which always faces away from Earth. The composition of the Moon’s near side is oddly different from its far side, and scientists think they finally understand why.
The Earth-Moon system’s history remains mysterious. Scientists believe the two formed when a Mars-sized body collided with the proto-Earth. Earth ended up being the larger daughter of this collision and retained enough heat to become tectonically active. The Moon, being smaller, likely cooled down faster and geologically ‘froze’. The apparent early dynamism of the Moon challenges this idea.
Officials from New Mexico, the federal government and Virgin Galactic met last week behind closed doors for the state’s first Space Valley Summit to form a “collaboratory” to promote Spaceport America and the state’s aerospace economy.
The one group not invited: taxpayers who have forked over about $250 million to build the spaceport where Virgin Galactic is the anchor tenant. As the Las Cruces Sun News dryly noted
Minutes after [Gov. Michelle Lujan Grisham] exhorted the summit to “make sure every New Mexican … knows exactly what is happening here,” all reporters were asked to leave.
