There is no printed booklet in the box. The Mars Rover build guide is published online as a web guide, with the components list and each assembly manual available as a downloadable PDF. It runs to well over a hundred photographs across a build of around 20 hours, which is why it works better on a screen you can zoom into than on paper.
How to print it
The guide is published as a set of downloadable PDFs rather than one file, so start from the guide page and download the parts you want:
Mars Rover build guide — components list plus the assembly manuals
Ultimate Mars Rover build guide — the same for the Ultimate kit, plus the Rover, Mission Control and Artemis Watch schematics
Open each PDF and print it as you would any other document. If you would rather print from the web page itself, use your browser's print function and choose "Save as PDF" first so you can check the page breaks before using paper.
A suggestion from experience: print the components list, and work from the screen for the assembly steps. The build takes around 20 hours and you will want to zoom in on the wiring photographs more than once.
If a PDF will not download or a page is missing, email [email protected] and tell us which one.
