Space

The achievements in the Space section are related to the space missions obtained from the fleet alert console on each character's personal starship, these are not related to the Galactic Starfighter matches. All of the missions can be completed with a single Imperial and Republic character, and each mission takes 5-10 minutes to complete. Although all bonus objectives for each space mission can be completed in one run of the missions, it sometimes takes practice to  get all bonus missions, and it is easier to focus on one bonus at a time to ensure you complete each one.
