Artemis II Model Beware

A Warning to Prospective Buyers of LEGO 10341 NASA Artemis Space Launch System

 

I want to share my experience with the LEGO 10341 NASA Artemis Space Launch System because I think prospective buyers should know what they may encounter.

 

I purchased this set approximately two months before the planned Artemis II launch. My goal was simple: build the model and have it completed in time for the launch. I was particularly excited about this set because Artemis is not just an interesting subject to me—it has been a significant part of my professional life.

 

I spent 40 years working for NASA and as an engineer, and I personally designed a number of systems associated with the Artemis spacecraft’s GN&C effort. So when I saw LEGO’s 3,601-piece Artemis model, I couldn’t resist. LEGO describes it as an accurate replica of the Artemis Space Launch System, and at $259.99, it is certainly positioned as a premium adult model.

 

Unfortunately, my experience has been extremely disappointing.

 

I have now encountered nearly 100 missing pieces in my set.

 

To be clear, LEGO has been willing to replace the missing pieces at no charge. I appreciate that. The problem is the turnaround time. I have been told that replacement pieces can take approximately three weeks to arrive.

 

And there is an even bigger problem: I don’t yet know how many additional pieces are missing.

 

I have not inventoried all 3,601 pieces against the approximately 300 pages of building instructions. Doing that would essentially require me to go through the entire instruction book in advance, identify every part required at every stage, and create my own inventory spreadsheet.

 

That isn’t a reasonable expectation for someone who purchased a LEGO set expecting to build it.

 

Instead, I discover missing pieces as I progress through the build. When I reach a step and the required piece isn’t there, the build stops. I request a replacement, wait several weeks, and then continue—until I encounter the next missing piece.

 

At this rate, a project I bought specifically to complete before the Artemis II launch could potentially take close to a year.

 

That is profoundly disappointing.

 

I’m not posting this because I expect LEGO to give me special treatment because of my NASA background. I’m posting it because people considering purchasing this $259.99 set deserve to know about my experience before they spend the money.

 

This is a 3,601-piece premium adult model representing a subject of enormous historical and engineering significance. For me, it was supposed to be a fun and meaningful way to celebrate a program I have spent much of my career working on.

 

Instead, I’m spending a significant amount of my time troubleshooting LEGO’s parts inventory.

 

I hope LEGO will take this experience seriously. Providing replacement pieces eventually is appreciated, but it doesn’t completely solve the problem when the customer has to repeatedly stop a 3,601-piece build and wait weeks for individual replacement shipments.

 

If you are considering buying LEGO 10341, I would strongly recommend that you understand this potential issue before purchasing it.

 

I would also be very interested in hearing from other owners of the 10341: Have you experienced significant numbers of missing pieces? If so, how many, and how far into the build did you discover them?

 

I’m interested in documenting the experience objectively rather than simply complaining.

Hi, thanks for posting. Can you please edit your post to use a smaller font? I understand that you may need the larger font at the end of your 40-year career, but it makes your post a little harder to read for me.

Sounds like you've had a very bad experience with this set. Speaking for myself, I did not have any missing pieces in my copy of set 10341.

You should probably inventory all the pieces before you continue, so that you can request all the missing pieces from Lego at once. You should probably have already done that. It's a bother, I know, but it's less of a bother to order the missing pieces once and receive them once than to stop-and-start the build many times as you continue from bag to bag discovering missing pieces.

Edit - You say you personally worked on a number of GN&C systems for Artemis. Can you tell us a little more about your work for the Artemis program? I'm graduating with my PhD pretty soon (knock on wood) and looking for jobs in space GN&C (knock on wood again), and during my master's program several years ago we regularly had guest speakers talk about their work planning trajectories or working on navigation problems for Orion, before the Artemis 1 mission plan had been finalized. I'd be fascinated to hear any stories you can tell about your work on Artemis and/or SLS.

Sounds like you had some really bad luck. A missing piece or two is always possible on any set, but this many is quite exceptional.
Considering the situation, I'm afraid getting the missing pieces from LEGO is really all you can do. If it's common parts you're missing, you can always take them from a later bag so your building isn't interrupted for every single missing piece. I can imagine it being a frustrating experience on a set of this size.

Despite all that, I hope you get all the missing pieces within a reasonable amount of time and can still enjoy the building experience.

Also like icm said, please use a regular size font (default preferably) to keep it comfortable to read for everyone.
