Everyone knows about the craters on the moon, right? The ones that look like a celestial game of golf gone horribly wrong? Well, a couple of them have been causing quite the ruckus amongst the scientific community. It seems these two particular craters weren’t caused by rogue space rocks, but rather something much more intriguing.

A team from the University of Arizona has been playing detective, and they’ve come up with a theory. They believe that one of the craters was formed by a Chinese rocket booster, which was carrying an unknown payload. Yep, an unknown payload. Now, if that doesn’t get your conspiracy-theorist juices flowing, I don’t know what will.

But wait, there’s more! This rocket booster supposedly broke off from a Chinese rocket launched back in 2014. But here’s where things get really interesting. The American research team also found that a second object of roughly the same weight as the booster landed on the moon, creating the other crater.

China, however, flatly denies these claims, insisting that the booster burned up upon re-entry into Earth’s atmosphere. But let’s be honest, we’ve all heard that one before. Meanwhile, the U.S. Space Command is sticking to its guns, stating that the objects definitely landed on the moon.

So, what’s the deal with this second object? Well, no one really knows. The American researchers think it might be a piece of space debris. But until China spills the beans, we’re left to our own devices to figure out what’s going on.

What we do know is this: space debris is no joke. As we continue to explore the great unknown, we need to be mindful of the mess we’re leaving behind. After all, we don’t want our legacy to be a bunch of junk floating around in space, do we?

And as for the identity of that second object? Well, that remains a mystery. But here’s hoping that China will cooperate with the investigation and shed some light on the situation. Until then, we’ll just have to keep guessing.
