A spacecraft is set to crash on the moon and it is unknown who launched it and where it came from. NASA believes it was launched from Earth eight years ago from another country. But that country denies it. Initially it was thought to be a SPACEX craft launched years ago. But now NASA believes it is the rocket booster from China's Chang'e 5 test vehicle which launched in October of 2014. The rocket was briefly in Earth orbit before it was sent it into a lunar transfer orbit. The test was for a future mission to land on the moon, collect samples and return them to Earth. China denies the craft is theirs however. Here is the rest of the story that is quite interesting, along with a video. (Courtesy 10WBNS)
