Remember back at the height of the pandemic, when the Chinese Yutu-2 rover discovered green blobs on the dark side of the moon? Well, if you somehow don’t remember that, here is my blog post from last year (spoiler, the blobs were lunar rocks). I mention this because the Yutu-2 lunar rover (which I am going to start fully translating as “Jade Rabbit 2” so it sounds less like a ballet dress) is now making international waves with a new discovery–a strange gray cube evocatively designated as 神秘小屋 “magic secret little hut.”

Courtesy of the Chinese space agency, here is a picture of this mysterious lunar object.

Wow! It, um, does look comparatively more like a magic secret little hut (or any sort of outbuilding, really) than the rest of the lunar regolith. As I write this, Jade Rabbit 2 is heading towards the mystery feature, so we should have a better answer about the lunar cube shortly. Based past Jade Rabbit discoveries, I am going to go on record and opine that this is a rock.

However a large square boulder is hardly a disappointment. There are no glaciers (currently) on the surface of the moon eroding erratics and carrying them around, so how did it form and get where it is? If, as seems likely, it was the result of a lunar impact event, then perhaps it can teach us something new about lunar basalt?

Finally, what can the Chinese teach us about drumming up space-exploration support with crazy names and press releases? Their square boulder has made international headlines (in an age of omicron and Olympics controversy!) just because it has a jazzy designation. Maybe we should start giving more space objects Chinese names (a development which is undoubtedly on its way, anyhow). We will keep our eyes on this lunar cube, in the off chance that little gray elves come out and try to sell strange lunar goods to Jade Rabbit. Off-world exploration doesn’t just teach us things: it is fun!
