Part 1: the problem
Say what the problem is and who needs what, compare the ways to solve it, and look at the missions that already exist.
The problem and the needs
Write the problem statement. Then list the stakeholders and their needs, each with a code such as N1, and the constraints and assumptions. Later requirements are traced back to these needs.

Compare the ways to solve it
Under Ways to solve it, add options such as ground sensors, aircraft or drones, existing data, or a space mission. Add the criteria that matter, give each a weight, and score every option from 0 to 5. The total out of 100 shows which option leads.
Record the decision, but nothing is locked
Write the decision and why. If space is not the best way, the study says so and the report records it, but you can still explore a space mission. The score is advice, not a gate.
Look at what already exists
Under Existing missions, search by the measurements the problem needs, add the missions worth noting, then decide: reuse, complement, or go for a new mission.
- Change the weights and the scores to see how the decision moves. The report keeps the final table.
