Grow Your Crew / More Crew Members

There's a few ways you can acquire more crew members:

1. Exploring derelict ships and stations, and finding hypersleep chambers with someone inside. You can free them from hypersleep by using your drafted crew member and interacting with the hypersleep chamber.
2. By taking other faction crew members as prisoners, and recruiting them over time. You can do this by boarding another faction spaceship, and then winning the crew combat that ensues. You know you have won the battle when speech bubbles appear over the heads of the other faction crew members, indicating they are willing to talk and give up. Use your drafted crew member to talk to one of them, and choose to take all crew members still alive as prisoners.
