Excerpt from The Official Residents’ Guide to Moon Base Alpha, © 2040 by National Aeronautics and Space Administration:
WELCOME TO MOON BASE ALPHA!
Congratulations on your selection as a resident of the first permanent extraterrestrial human habitat! To ease your transition from earth, Moon Base Alpha (referred to from here on as “MBA”) has been designed to feel as comfortable and familiar as any residence on our home planet. Our engineers and designers have spared no expense to provide all MBA residents—or “lunarnauts”—with everything they need for a relaxing, pleasurable existence.
However, life on the moon will not be without challenges. There are obviously many differences between this residence and one on earth—many of which you may be pleasantly surprised by! To that end, please take the necessary time to read this helpful, informative manual in its entirety, as it will likely answer any questions you have about your new home (and perhaps a few questions you hadn’t even thought to ask yet)!
Once again, congratulations on your selection. Welcome to the moon. Enjoy your new home!
