Moon Rock from Apollo 11 Sent Back Into Space

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."
