Destiny 2's Shadowkeeper has a cute little NASA Easter Egg located on the moon. The orbital mapper emblem looks very inspired by the NASA flag and you can find it in the Lost Sector of K1 Logistics.
Destiny 2 - How to get the Orbital Catographer Emblem - NASA Easter Egg
To get to the K1 Logistics Lost Sector, launch out at Eris Morn, then head to the Archer Line going left on your sparrow. Just go in a straight line. When you reach the large building at the end, enter and go immediately left, right, and follow the broken corridor to the Lost Sector. The video above will help you get there.
You have to fight your way through the lost sectors on the Moon, killing all the enemies to open the barriers that block your way. When you reach the end, you will come to a large open space with a servant. You don't need to worry about this guy, just look across the arena. You will see a low level gray building and you want to walk up to the roof.
When you get to the roof, you'll find a small, crashed satellite that you can interact with. You will thus obtain the emblem of the orbital cartographer! Now you can either kill the Servant and complete the Lost Sector, or just go away using the map to spawn in Eris Morn.
If you want to kill the Servant, take out the Nightmares to knock down the shield, then use ham in it with whatever weapons you have in hand. It's a pretty tough fight if you're on low power, but it won't be a problem for anyone who has played the game for a little while.
So there you go, Guardian! The Orbital Mapper Emblem is now yours.
