Citizen Sleeper 2: Starward Vector

This achievement is for succesfully completing a contract to survey an ice asteroid and extract a drill sample from its core to confirm its suitability to be harvested for drinking water.

You get this from the captain of the damaged water freighter that is docked to the port section of the Spindle if you put in volunteer work to contain the damage and safe most of its water freight. This is on a relatively short cycle clock once you uncovered it by exploring the port section, so be ready to put your good dice into that once the emergency call happens. It's helpful to explore the middle section of the spindle before the port section, so you have unlocked a place to buy food before you trigger that event.

I don't know whether there is an alternative way to get the ice asteroid contract if you fail to help the water freighter, will update after I find out.

The contract itself isn't on a time schedule and is relatively easy, you just mustn't rack up too many faillures on critical actions to avoid breaking the asteroid apart. The final part of the mission (drilling to the core after finding a good spot) must be done with endure and is dangerous, so if you aren't proficient in endure, make sure to take a crew member who is. Serafin will be reduced to pilote duty only after the intro, but you can recruit Yu-Jin as a replacement after buying drinks four times in the kelp bar on the same station).

Exploring the mysterious man-made shaft on the asteroid is optional and can be done after completing the main objective, it will give you some scrap loot and some mysterious old Solheim data (nothing unique, the same type of data can be scavanged infinitely in the Helion Gate ruins, so feel free to just skip the shaft if the asteroid stability and/or your provisions run low).

(If you do it soon after arriving at the Spindle, Serafin will still be hurt and can't work as crew, but you can recruit Yu-Jin as a replacement after buying drinks four times in the kelp bar on the same station).
