Precedents: 

Describe the prior work, ideas and projects that influenced your design. What work informed this idea. What other technologies, tools or investigations did you draw on.

  For our precedent studies, we researched aeroponic systems and analyzed their costs and benefits. An aeroponic system removes the need for a growing medium, and having a low pressure system instead of a high pressure system simplifies the project in terms of required systems. While the existing systems that are successful here on earth may not be completely fit for a Martian habitat, they still provide a good indication of what plants need, and how people have used different techniques use the surrounding habitat for their advantage. The precedents and projects that we looked at mainly inspired the whole idea of using a low-pressure aeroponic system; the specific systems we chose and their designs were based on intuition and self-analysis.
