I bolded out the part that's not the FSS, but the DSS, and the part which doesn't need to be done. There's no need to fly to every planet and shoot it with the DSS, unless you're a hardcore completionist.Am I really that slow? With 21 bodies to find and classify on the FSS and then 6 of those (5 heavy metal worlds & 1 gas giant with water based life) to fly to and scan in detail, is an hour very slow? Please keep in mind I have only been at this new found exploration method for a week or so & I am much faster at the FSS than I was.
Completing the DSS's "shoot the planet" minigame rewards you with:
1. the exact locations of all the surface sites on the planet, if there are any (just scanning with the FSS tells you the number and types of sites)
2. more credits
3. a "First Mapped by" tag in addition to the "First Discovered by"
In other words, if it's a planet that has no sites (the FSS tells you about them), and not valuable, and you don't want two tags on it, then it's a waste of time to fly to it. These will make up the vast majority of bodies you'll find.
