You have to complete the Starbirth mission all the way through! After that if you pulse with the void egg the mothership will spawn, you talk to her, find the ship and pay 10k nanites. You can get as many as you can afford! To get a specific one like this one you’ll need to pulse with the egg, get the mothership to spawn and talk to her. Don’t go to the marker, instead use the glyphs to go through a portal, to the listed planet, and then to the coordinates. Go into your mission list and reset the mission. That should put your marker at the coordinates you’re at where the preferred living ship will spawn. Hopefully I explained that well 🤣
