Biological Cargo Bay

Biological Cargo Bay is a space mission building used to bring back living biological material from specific destinations. It allows Duplicants to retrieve alien plants and wildlife from space, making it useful both for expanding a colony’s renewable resources and for recovering species that have become unavailable on the home asteroid.

Its listed destinations and returns include Smooth Hatch from the Metallic Asteroid; Stone Hatch from the Rocky Asteroid; Wort Seed and Sleet Wheat Grain from Interstellar Ice; Gassy Moo and Gas Grass Seed from the Organic Mass; Blossom Seed and Pacu Egg from the Terrestrial Planet; Pokeshell from the Arid Planet; Pip and Arbor Acorn from the Living Planet; and Dasha Saltvine Seed from the Salty Dwarf. The bay has a declared capacity of 100 kg, but in practice it usually comes back with less than that maximum.

A few practical details matter when using it:

• Ice planets and the Printing Pod are the only sources of Wort Seeds aside from the Wheezeworts initially generated on the starting asteroid, while Organic Mass is the only source of Gassy Moo and Gas Grass.
• Most of its other returns are mainly valuable for bringing critters back from extinction or reintroducing them to the colony.
• Destroying the building drops all contents to the ground.
• If a critter is inside, it is better to wait until Duplicants relocate it and then dismantle it, rather than losing time capturing it manually. Building a Gantry and Critter Drop-Off in a Stable can help with this process and reduce the risk of the critter dying in the extreme environment of the Space Biome.
