As we told before, during this semester we are building Mars Chamber, which is able to simulate some of the Mars’ conditions. It has to be at least 1 m3 volume cell with possibility to change temperature in a wide range from +50°C to – 100 °C (323K-173K) and keep the set up temperature as stable as possible. One more important requirement for the chamber is to create low pressure inside of it. Air pressure on Mars is just 0,6% from the one we have on Earth. Quite a lot of brainstorming will be needed to make this whole system as cheap as possible, since we want the chamber be not only reliable and safe, but also affordable. Low price would mean that more people can test their products for suitability on Mars.
