SpaceX Rocket Impact on Moon

Well, in the early hours of Wednesday, August 5th,

a upper stage from a SpaceX Falcon 9 rocket

made an unplanned impact on the lunar surface.

This Falcon 9 upper stage was from a January 2025

launch that successfully deployed Firefly Aerospace's Blue Ghost 1 lander

through NASA's CLPS initiative, or the Commercial Lunar Payload Services.

A combination of solar activity and gravitational forces

actually prompted the unplanned impact.

NASA did not purposely plan to have this

upper stage impact the moon.

However, this is not something we're really concerned about.

This is actually a technically accepted and safe method

of disposing of hardware in low lunar orbit.

And in some cases, mission operators

actually choose to end their mission by impacting their hardware

on the lunar surface because it's a predictable and trackable strategy

for end of life hardware disposal.

This poses absolutely no danger to anyone on Earth or

any hardware on the moon. And in fact,

scientists are eager to study this impact event

as it can help us constrain how to track things like this in the future.

We love the moon for so many reasons.

And one of those reasons is that it's a natural laboratory

for processes happening all over the solar system.

There's no atmosphere or environment.

And the regolith, or the surface of the moon,

is stable over really long periods of time.

Impact cratering especially is a process that occurs across the entire solar system.

And by impacting an object of known size

at a known velocity into the lunar surface,

it can help scientists constrain the impact cratering process

and what kind of impact crater results from an impact of that size.

The moon is always being hit by things.

Meteors,

asteroids,

comets, and things hit the moon all the time

across its four billion year old history.

In fact, Artemis II astronauts actually observed several active impact flashes

or craters forming on the lunar surface during just their several hour flyby.
