5. when there is no solution to the problem that meets the criteria and
constraints, engineers often revisit the problem. the engineering
problem can be redefined or the criteria and constraints can be
changed. list at least three changes that could be made to the criteria
and constraints of this problem that would be feasible and that might
allow you to find an engineering solution. (changing the length of time
that the crew is in space is not a feasible option, for health reasons.)
