The Problem

Limited lifetime of supplies and the lack of adequate manufacturing options on remote expeditions make space travel difficult. Sending one kg payload to space costs $20,000!1 One take-off pollutes earth with up to 300,000kg CO2 which is equal to the carbon emission of 73 cars per year!2

Our Solution

Our mission is to establish an independent and self-sustaining alternative manufacturing system. Our desired system contains a 3D-printable bioink produced by certain bacteria and is based on a combination of the biopolymers alginate and cellulose. Our captain who will accompany us on our flight is Azotobacter vinelandii, a heterotrophic soil bacterium which produces alginate naturally. We are introducing genes required for cellulose biosynthesis and alginate overexpression in order to create our hydrogel which has the required mechanical properties to be used as bioink.


Astronauts wil be more autonomous.
With the help of our bioink they would be able to print whatever they want, whenever they need it. Not just limited lifetime equipment, but also “luxury goods” which astronauts would not be able to take with them without having our bioink. In the long run, using our bioink instead of sending consumables to space would be more sustainable and space saving.
