Lab 1.5: Solar Power on Satellite
NASA has hired you to design the solar power system for the newest satellite it is planning to launch. In this system, there are many design
constraints that affect the overall satellite's performance. A few of those constraints will be explored in this question.

Task 1
% The overall satellite's weight is limited to 10 metric tons. 9 tons is reserved for instruments and
%the satellite's chassis.
% This gives a weight budget of 1 ton for solar panels. How many panels can be used for each type of
solar panel listed in the
% table above, while meeting the 1 ton weight limit?
Task 2
% Using results from Taskl, how much total poer is available for each solar panel type?
Task 3
% Using results from Task 1, how much does it cost to use each solar panel type?
Task 4
% Using results from Task 1, how much does it cost to use each solar panel type?
Task 5
% A last minute decision limits the area of the solar panel array.
% The area for the solar panel array on the satellite is
% now limited to 200 square meters. There is no restriction on widht and lengths.
% Re-calculate the watts-per-dollar metric.
