You’re entitled to take two personal items with you which will be useful or fun to use even in zero gravity. Show us what these items will be in a drawing or collage. Thinking that the electronics/communications/food/clothing will be taken care of by NASA….I would take the following two items: a box of colored pencils and this journal, entitled never stop thinking. Surely I will want to capture what I see and the old school way is good. Surely I will hear, see, taste, touch, smell, or think of somethings that I will want to record pictorially or with words! I would not want to loose those precious stepping stones!
