A SpaceX rocket part is going to crash into the Moon on Wednesday at 7:35 am. It's traveling at a speed of about 8,700 kilometers per hour, which is seven times faster than the speed of sound. This rocket part was once a part of a SpaceX Falcon 9 rocket that was launched in 2015 to put a satellite into orbit. After the rocket finished its job, the second stage stayed in space and has been floating around ever since. Scientists say this crash won't hurt the Moon. The Moon gets hit by small asteroids and comets all the time, but they don't do much damage. This event is a great chance for kids to learn more about space and science. Who knows, maybe one day you'll get to explore space and see what's out there!
