So it begins, 2017. During this spring we are going to build the prototype of our Mars Chamber. Currently we are gathering information about materials: quality, availability, prices, suppliers and so on. We hope to make orders in next two weeks and start building.
Yesterday we were testing PEUHMW plastic. Idea is that our chamber’s outer layer could be made out of this material and main purpose is to reduce total weight.
In our test it managed to hold vacuum and we also tried to weld two pieces together, which also worked pretty well. We still need to do some endurance and low temperature testing.
