Essay section planning & title changes

In a recent taught session I set out a plan of my essay and improved it by adding more specific parts to each individual section.

 In addition after taking into account feed back that I have received from my supervisor and centre coordinator I have changed the working title of my EPQ topic from
'How will cosmic rays affect the crew of a potential mars mission and how can they be protected from them?' to 
'To what extent will cosmic rays be a danger to a potential mars mission?'.
My previous title was too descriptive and limited the potential to evaluate, whereas my new title is more evaluative than descriptive and gives me the chance to broaden and improve my essay's eventual conclusion.
