Imagine you are part of the team planning and designing the first manned mission to Mars. 

Your job is to investigate just one problem of the mission, and come up with an idea that might solve it. 

You’re asked to create a poster to explain the problem and how your idea might solve it. 

The idea can be anything you like, but it must be based on 

Your poster must be no bigger than an A1-sized sheet of paper (841 mm x 594 mm).

It must be well-presented, with pictures and diagrams and not too much writing (and not too small).
