Safely tucked away in every manned spacecraft that leaves Earth for other places should be a very important book. A book that will tell people how to go from pounding stones to building their own spacecraft. Every step and option in between will be covered. A how-to of all that humanity has done since it first started using its individual brains. No known technique, procedure, or method can be left out. Anything considered propriety on Earth might be perilous not to know for a person out of reach of Earth. All things known to humanity down to the finest detail will need to be in this book. When we send people to the stars, let them have the most power we can possibly give them: knowledge. The freely-accessed collected sum of all knowledge will be the Ultimate Open Source.
