I will definitely start to read this out loud to my 5 year old. He will love it. Thanks for sharing your finding.

Just FYI. Almost every launcher that offers commercial services has such a user manual. I was involved in preparing one such manual. A collection of these manuals can be quite entertaining for 5 year olds. You should be able to easily find them from the websites of the respective companies or agencies.

Thanks for the tip. I only knew about old manuals of the space shuttle.

I think the Spacecraft Interfaces section (starting page 84) is the bit that might interest HN readers. It describes (to potential customers) the dimensions of the payload bay, electrical and comms interfaces available, conditions the payload must be able to tolerate (vibration, temperature etc).
