No Man's Sky: 13 Little-Known Facts You Need To See
7. You Get Paid For Logging Information
One of the game's big draws is that you can log information about a given planet (such as naming the animals residing there) on the various stations you'll find, and if another player visits this planet, they'll be able to see any info you've left behind.
Furthermore, as logging information is a "service" in the game, you will be rewarded in Units (the game's currency) every time you upload some details to one of the stations.
Though this likely won't be as lucrative as some of the game's other means of acquiring money, it's still a good way to encourage exploration and sharing your space-faring with others.
