Build the Constellation program's crew launch vehicle, Ares I and its concept demonstrator, Ares I-X!

This is a recreation of NASA's Ares I and Ares I-X rockets built at 1:110 scale, the same scale as the LEGO® Saturn V set! The models have sturdy constructions and are designed to be scale-accurate in everything from the exterior dimensions to details. The product includes two different rocket models, as well as a small display stand.

The Ares I stands 86 cm (34 in) tall and consists of 799 pieces that cost around $50 (excl. shipping).

The largest model, Ares I-X, stands 89 cm (35 in) tall and consists of 741 pieces that cost around $45 (excl. shipping).

The bricks are bought separately following the "How to buy the bricks" section below.

The models feature:

  • Accurate staging with strong connections between the stages and detailed engine sections.
  • A highly detailed small stand based on the Mobile Launcher that is recommended for vertical display of the narrow rockets.
  • Raceways, fueling ports, and many more details for you to explore!

The digital building instructions you'll receive with your purchase are high-quality and easy to follow, even for less experienced builders.

Learn more about the Ares I and Ares I-X:

The Ares I was the crew launch vehicle that was being developed by NASA as part of the Constellation program. Originally known as the "Crew Launch Vehicle". It was intended to launch the Orion spacecraft after the Space Shuttle was retired in 2011 to launch crewed missions to the ISS or beyond Earth. Ares I was to complement the larger cargo launch vehicle Ares V. Due to the cancellation of Constellation program in 2010 the only flown vehicle was the Ares I-X prototype and design concept demonstrator in October 2009. However, some of the developments - like Orion spacecraft, 5 segment SRB's or engine manufacturing techniques, Mobile Launcher - were later reused in Artemis program during the development of Space Launch System.

This model was designed by saxus and if you are considering buying the instructions we are especially grateful to you for supporting our work and directly enabling us to continue producing more designs in the future!

34 in x 2.5 in x 2.5 in

Ares I-X is taller, at 89 cm (35 in) tall.

Internal colors:

The model includes internal colors which aren't visible when the model is completed. Replacing these reduces the piece price, but can make the building process more complicated, especially if you aren't an experienced MOC builder. Consult the included color guide in the instructions for further details.

The following colors can all be replaced by "Any color" when exporting the pieces to BrickLink: bright light blue, green and magenta.


This product includes three models, which you'll all have access to with the single purchase. Use these explanations to determine which instructions to use and parts you need to buy to build your desired variant:

1. Ares I [799 pcs] - builds the Ares I Crew Launch Vehicle (medium nougat second stage).

2. Ares I-X [741 pcs] - builds the Ares I-X design concept demonstrator (all white second stage).

A. Ares Mini MLP Stand [655 pcs] - only builds the small display stand. Recommended for safe vertical display of the rocket model.

How to buy the bricks

I recommend buying the bricks required for the model from, which is the largest online marketplace for LEGO® parts sellers.

There are other alternatives, like the official LEGO® Pick a Brick site, but they rarely have all the required pieces and it's often more expensive there.

The process to buy from Bricklink is easier than it seems, and is explained thoroughly in this step-by-step guide to help you:

  1. After buying the product, you need to download the folder named "Part lists" and unzip it.
  2. Choose the part list(s) you want to buy using the guide in the "Variants" tab below.
  3. Next go to and log in or create an account (it's very easy to set up).
  4. Click on the "Want" tab in the top right corner and "Create New List".
  5. Once you've done that, click on the upload button and drag and drop the part list you want to include in the order. Then click the blue "Proceed to verify items" button.
    Repeat step 5 for each part list you want to order.
  6. [Optional step if you want to slightly reduce the part cost] In the wanted list, you can sort by colors and select all the internal pieces (described in "Product specifications" above) and click on "Color" and apply "Non applicable" since all those colors can be substituted without affecting the exterior look.
  7. [Optional step if you only want new pieces] Select all the pieces and change their "Condition" to "New" (needs to be repeated for each page). Note that this will lead to a higher price and the risk of some parts being unavailable. The default option gives you a price around the estimate and will include both new and used bricks.
  8. Next click the green "Buy All" button and then adjust the settings to your preference. For lower shipping costs, I recommend beginning by choosing your region/country first and only change it if the pieces aren't available there.
  9. Once that's done, click the blue "Auto-select" button, uncheck the box in the pop-up and click "Start".
  10. This will give you a list of stores whose orders together will include all of the pieces in your wanted list. Confirm that all the pieces are included by clicking the "Wanted Items" tab to the left and control that there aren't any pieces left there.
  11. If you are happy with the selection and price, click "Create carts", followed by "Checkout" for each individual store and buy the pieces!
    (If you are not happy with the price or if you're missing any pieces, you can click "Remove All" and redo the auto-selection with different settings)

If you're having any issues with ordering your bricks, don't hesitate to send us a message through the "Contact us" tab in the menu and we'll do out best to help!
