Quick build, fun to play with, educational
If you’re new to the Technic line, this is an incredibly rewarding build to start with. It offers a clever, straightforward demonstration of how gears and levers interact. A great design touch is the functioning gearbox lid, which lets you easily peek at the internal mechanisms once the build is complete. My only critique is that the back of the main booster lacks full structural coverage, as enclosing it would make a more realistic active play. Still, it's an absolute must-have build for kids and adults alike.

Review: LEGO Technic NASA Artemis Space Launch System Rocket 42221
My 6-year-old grandson is a big fan of space shuttles. He absolutely loves this one and finished it in 6 days. The instructions are incredibly clear; my son only showed him how to read them on the first couple of pages, and after that, he put all the pieces together almost entirely by himself. The multiple movable gears and space arms are well designed and work perfectly. The final product is durable and looks fantastic.

Poor delivery
It is a great Lego set, but when I ordered it, it was supposed to arrive in about five days, which was going to beperfect as my grandson was going to be visiting and it was for him. The day it was scheduled, I got a notice saying it wasgoing to be three more days, arriving on a Thursday. It did not arrive on Thursday. It did not arrive on Friday. It did not arrive on Saturday. It did not arrive the followingMonday. I just picked it up. When I looked at the tracking during all of that time, which was FedEx, it sat in Connecticut for aboutthree days, and then it sat in Springfield, Massachusetts for about three days before it was delivered about 40 minutes west of Springfield. I'm very disappointed in the shipping and the fact that the gift did not arrive in time for me to do with my grandson.

amount of purchase
I like the item. I really hate how Target gives an amount when you order and later the amount is always increased due to sale tax. isn't Target smart enough to know the sales tax when the purchase is made? I'm really getting hesitant about ordering on line because Target can't show me what I will be charged.

The Lego was delivered but you did not put the Lego set in a bag so now it’s sitting out in the open so the whole apartment complex can see it’s a lego set!! Why would you not put the lego set in a bag! I just hope it’s still there when I get home this afternoon.

I was very excited to get this set and build it. I've loved LEGO for years, but I had received a duplicate of a bag instead of the last bag I needed. I was so upset :(( It's only half way done since I don't have the bag of pieces I needed, but it still looks amazing and I love the mechanics

First Space Craft
A fun start to building further space crafts. I did find it difficult at times to distinguish between certain colors, but was able to logically work it out. I would like to see a better way of placing the decals in the box, with the movement of the bags oG bricks, several came apart from their sheet and stuck to the inside of the box. Maybe package them separately so that won’t occur.

Interactive fun
This build is so Interactive. It moves, has interactive connected pieces that my son absolutely loves. I think it's one of the most entertaining sets he's built since he can play with it instead of it just sitting there once it's done

Fun in a box
[This review was collected as part of a promotion.] Fab set. My daughter loves space and building so putting the two together is perfect. Instructions are easy to follow and gives a whole lot of fun to the builder

Launch into fun!
What a fun build! Normally I'm not much of a technic builder, but I may have to change that. This was a super satisfying build where the functionality truly brought it to the next level. How incredibly satisfying to get to 'launch' the Artemis II after putting it together! This is a win for Technic and non Technic fans alike and a must have for any fans of space!
