CNSA Long March 5 - Tianwen-1 Mission

Wow, thanks to every single one of our supporters so far!

5,000 here we come!!!

Check out this cool comparison pic, showing the detail and accuracy when compared to its real life counterpart.

Hi fellow Lego Space enthusiasts, 

Our sincere appreciation goes out to all 3,000 of you.

We want to thank the amazing people and sites letting supporters know about this project, particularly those promoting it in Chinese.

Again, thank you for being one of our first 3,000 supporters…10,000 here we come!

Valerie & Matthew

Thanks everyone for embracing this project and racing us to 2,000 supporters in just over a week! It's fantastic. We really weren't sure what the reaction would be from tackling a non-US space agency rocket and we're so pleased that space fans world wide are just like us and lovers of all space rockets.

3,000 here we come!

As a thank you to all the supporters who have taken us to this first huge milestone, and left so many kind comments about the accuracy of this project, we want to share with you how this was achieved.

We been building Lego rockets and spacecraft since 2014, yet nothing could prepare us for the challenge of designing the Long March 5. Not only was there comparatively modest information about the rocket, its functionality and Launch Platform, there were very few specifics about the height and diameter released outside the core and boosters.

After much searching and studying of countless pictures, reports and videos, Valerie's husband Gilles utilised his high school maths to analyse each one and calculate the exact measurements needed using the parallax. Simply put, the Parallax is the difference in the apparent position of an object viewed along two different lines of sight, and is measured by the angle or semi-angle of inclination between those two lines. This yielded each measurement needed for the rocket and the Launch Platform.

Below is the actual measurements diagrams developed (measurements removed), along with the comparison pictures we used to make sure our 1:110 scale model matched it's real life counterpart.

We look forward to further updates and want to thank again all the supporters for this project, it's very exciting!
