The Moon!

The final published copy of The Ultimate Coach was not ready in time for preparations for sending to the Moon aboard the Peregrine Lander.

However, a copy of Steve's document (included in the book) was prepared and included in the manifest for the Peregrine Lunar Lander, to be launched from Florida in 2022, via a United Launch Alliance Vulcan Centaur rocket in the VC2S configuration.
