Hey, all! Bungie has added this information to their API so you can now track specifically which you’re missing. Be careful which guide you’re using to find these locations however, as many are incomplete or poorly describe the locations. https://lowlidev.com.au/destiny/maps/mars You can also track which Sleeper Nodes you’ve already opened if you’re like me and don’t want to keep opening duplicates. Happy hunting, Guardians.
