AaronW writes "According to a story at space.com, Earth may once have had two moons. The smaller moon, estimated to be 750 miles (1200km) wide and only 4% of the mass of the larger moon, crashed into the far side of the larger moon which caused the features we see today on the moon. The surface of the far side of the moon is quite different than the side facing the earth, having a different composition and a much rougher terrain."

AaronW writes "According to this article at collectspace.com, a rock collected by Neil Armstrong during the Apollo 11 mission was quietly sent up to the ISS back in March. It was sent up in a special case to protect it with instructions given to the astronauts to not open it. Contamination isn't a huge issue since the rock sample had already been exposed to the air and was not that remarkable, resembling Hawaiian lava. It will be revealed tonight for a 40th anniversary celebration at the National Air and Space Museum in Washington DC."
