All 3 available shuttles are crafted in the Large Printer, which is unlocked from the start.
Each shuttle has a space for an Oxygenator, and allows for an oxygen network to be established on a new planet as long as the Shuttle remains connected. The 2 bigger Shuttles additionally offer a cargo area to store some items, the Medium Shutle has 2 Medium slots while the Large Shuttle has 2 Large slots, meaning that larger packages or more Medium Storage modules can be carried on each flight.
