Now, we'll do the most basic modifications (For Windows). Changing the names of programs and spacecraft.

Spacecraft Description Editing
First of all, go to your BASPM files. Hunt down the folder "SPM-Windows_Data".
Then go to "Scripts", then "Text Scripts", then "General Container", then "EN".
The text containing the program descriptions are located at "Program StringsEN". Open it in Notepad. Hunt down the text you wish to edit/rename (However, you can always go to Edit, go to Find, then type in the name of the pacecraft you wish to change) . In this instance, I will be editing the text of the Micrometeorite to "AEIOU".

Here it is!

Go ahead and get creative!

By the way, fun fact of the day....the lunar spacecraft are, in fact, IN THE FILES, but are not actively in the game. I've found plenty of references to direct ascent Gemini lunar missions, LEMs, and something about a "short-term" lunar habitation module.
(TESTED. NO ILL EFFECTS OBSERVED!)
How to Make A Program Give You More Prestige
Admit it. Sometimes, you just need some Prestige to move to the next level of funding so you can buy that nice new shiny probe and send it to another planet on a nice new shiny big powerful rocket. This is how you could do it.
First of all, before doing anything, head to your BASPM folder/files.
Go to SPM-Windows_Data, then go to scripts, then Data Scripts, and finally, go to General Container. Once you are at General Container, go to MsnCnfg00-01...that's the Sputnik Mission. Once you open it, you'll see the text similar to this.
Take the script, and edit it the bold areas to the numbers you want.<MsnCnfgsList>

Congratulations! You can now earn 99999999999999999x10 Prestige froma simple satellite mission and buy that nice new shiny probe! But a warning note.
