A spent SpaceX Falcon 9 rocket is expected to slam into the moon, creating an unusual skywatching event for astronomers and telescope owners. Reports indicate the impact is scheduled for Wednesday at around 6:34 am UTC, when the inactive booster reaches the lunar surface.
Scientists are interested because the collision should throw up a cloud of debris above the moon. That plume may rise high enough to be detected from Earth, and under the right viewing conditions it could be visible through sufficiently powerful telescopes.
For observers, the event is notable because impacts on the moon are rarely watched in real time from Earth with this level of anticipation. Even if the crash itself is difficult to see directly, astronomers will be monitoring for the aftermath, especially the dust and debris kicked up from the surface.
The expected Falcon 9 moon crash also highlights what can happen to spacecraft hardware long after a mission ends. In this case, a dead rocket stage is set to become part of a closely watched lunar impact, turning space debris into a brief but scientifically interesting event.
