There's few other generic-ish space sets you can find just by putting "space" into the search bar on the Lego site:

https://www.lego.com/en-be/product/lunar-roving-vehicle-6034... (cheaper, similar play value)

https://www.lego.com/en-be/product/lunar-space-station-60349 (slightly more expensive, bigger)

https://www.lego.com/en-be/product/lunar-research-base-60350 (more expensive, but much bigger)

The space sets are definitely there in general, they're just a sub-theme of "City" now for some reason.

There's also a few space fantasy sets under the Monkie Kid line, like https://www.lego.com/en-be/product/chang-e-moon-cake-factory... and its rabbit-piloted moon mecha.

In my head, Euros are worth basically the same, maybe a little bit more, than USD. But the US version of that set is only $40 (although it's sold out, so maybe the EU version is higher in price due to scarcity). https://www.lego.com/en-us/product/space-shuttle-adventure-3...

EU has about 20% VAT, but even taking that into account it's still more expensive
