Our first project is to design, prototype, and manufacture a functional and collapsible airlock by September 2018. We do not plan on stopping there, however, our sights are set on much loftier goals. We hope that this project will inspire other universities to join us, so that we may create Mars Colony competitions, reflected through projects beyond just this one.
Current unfinished model of our collapsible airlock
Conceptualization, design, and initial testing
We will be researching the effects of the Martian planet: atmosphere, current airlock designs, and space programs during the Fall, 2016. This will provide us time to organize ourselves before we tackle the design stage, and figure out the necessary components to able to begin testing. Next, we are going to come up with a design for how the airlock is going to function, putting all the pieces together. To validate our design, we are going to prototype the different systems using physical and analytical models and constantly improve on them.
Tests to perform:
- Pressure testing different materials, such as a frame cover, to see if it can withstand the 102.7 kPa difference in pressure on its own, or with a cage
- Pressure testing main structure’s seals
- Puncturing fabric to understand the failure modes so that we can look into solutions in the event of a catastrophic failure
- Controlling pumps and motors both autonomously and with user input.
- Validating door mechanisms
Prototyping, manufacturing, and iteration
With a detailed design created from what we learned in the first year, we will start testing and putting together the larger mechanisms that will be a part of the airlock. Electrically, we will be creating the circuits to control the system. Structurally, the design is going to be verified through physical and analytical prototypes. During this time, we will find suppliers and manufacture the components and order whatever is necessary. Meanwhile, the team will implement cost/mass saving methods to create a better solution. Once this is completed, we will iterate through the design and improve it until it is time to build. Finally, our team will assemble the airlock in a mock capsule, reassemble it like we would on Mars, troubleshoot any problems that arise, and show the world our design.
To measure our success, we will test in conditions similar to the Martian environment. The plan is to pressurize the inside of our airlock to represent the pressure difference between Mars and habitable air pressure. Our expectation is to build a working model of at least 75% full scale by the end of September 2018.
Ambitions for the Future: Hosting Competitions
Starting with UBC as the only university involved, we hope that other institutions will jump on board after they see what we can do. This can be achieved by spreading word of our team and defining a unique and challenging competition for others to compete in. First, however, we need to have something to show for ourselves, and our airlock project will do this.
With many different potential projects, competitions will be enabled to change throughout time.
Potential Projects to work on, and compete towards:
Airlock design and emergency depressurization measures(already started)
- Air Recycling Systems
- Water Reclamation Systems
- Communications Systems
- Oxygen production
- Proof of concept ISRU (In Situ Resource Utilization) systems for obtaining resources
- Agricultural tests on simulated soils
- Rovers for human transport or control
These are a lot of different areas to explore, some being more feasible than others. In the future, we can begin combining these projects as the team grows and matures. As a result, the projects will reflect a more complete Martian colony-the ultimate end goal of the UBC Mars Colony team.
Our team isn’t limited to Engineering students! The UBC Mars Colony team would benefit by including people of related specialties, broadening the realms of what is possible and creating a more rounded, realistic basis for our Martian colony. Soon, we will be in the process of putting together a research division to look into related colony projects. Some fields that could have related projects include:
- Architecture – Designing models and mock-ups of possible designs of the colony
- Psychology – Understanding the impact on a person’s mental state by living in an enclosed space
- Sociology – Understanding interactions between people in this limited environment
- Land and Food Systems – Agriculture of crops on Mars
- Biology – Researching the optimal organisms to convert CO2 emissions to oxygen for human survival.
- Chemistry – Researching reactions like the Sabatier reaction to produce methane and oxygen for the colony, and helping with oxygen conversion
- Geology – Understanding and modelling the compositions on Mars
