Starfield gives players galaxies to explore alongside an epic main story. Exploring planets is optional, but doing so rewards players with XP and resources. Both Constellation and LIST will pay the player to survey planets throughout the universe. There also are side missions that involve 100% scanning a planet for its survey data.
