Rocket to crash into Moon at speed of 8,700 kmph: Will it be visible from Earth?

A piece of SpaceX's Falcon-9 rocket will slam into the Moon at 8,700 kmph on August 5. Astronomers said the impact itself is unlikely to be visible from Earth. However, they hope a dust plume might show up through telescopes. This event helps researchers study how craters form on the Moon.
