The moon phase stickers are wrong and there is no way to rearrange them to the correct order. It would have been simple to either research the moon phases or make the stickers so they could be put in the correct order. It's infuriating. It was pretty simple to build and the instructions are clear. The ratios are pretty good and appreciate that the earth has an axial tilt. Would have been better if the sun was an actual build and not just two parts.

I wish they would have thought about the moon phases when printing the 4 stickers. 3 & 4 are identical so you don't have an accurate moon phase with this build. I am a nerd and printed my own sticker and it's close enough

technic legos are great for helping boy build

I'd been on the lookout for a set like this for a while (space, mechanical, Technic) and was so happy when this was announced - even happier putting it together! I put it together once myself and then had my students assemble it shortly after to coincide with a total solar eclipse that occurred in our area. I've put together many sets with my classes over the years (Haunted House, Crane Truck, ISS to name a few), but this was the first that really captured the engineering spirit I try to reinforce in many of my lessons. It was straight up too hard for quite a few students who couldn't follow directions or recognize one gear instead of another. In my opinion though, that was perfect as it afforded those who did understand the opportunity to tear it down and problem solve with their classmates. I'll never forget the look of accomplishment on the student who finished it when they turned the crank and it worked - truly magical. Anyways, thank you for making this set - would love to see something mechanical for other branches of science!

Slightly challenging to align the gears just right, but excellent build and super fun to play with. Definitely an impressive model.
