How does a space mission move from an idea into the real world?

The NASA Space Program Tube follows the complete public-facing journey: a need becomes an objective, the objective becomes a mission, mathematics makes the problem calculable, engineering makes the solution buildable, Mission Control coordinates execution, people and machines act in the world, telemetry returns, and each mission leaves knowledge for the next.

Read the 25-stage journey

1. Need and opportunity — Why go?
2. Mandate and authority — Who decides?
3. Funding and resources — What can be sustained?
4. Mission objective — What must be achieved?
5. Mission architecture — What capabilities must exist?
6. Mission analysis — What does the journey require?
7. Mathematics — Make the mission calculable
8. Technology development — Build what does not yet exist
9. Systems trades — Choose between good options
10. Detailed design — Turn architecture into buildable parts
11. Suppliers and partners — A mission has an industrial network
12. Manufacturing — Turn design into reliable hardware
13. Software and avionics — The information system inside the vehicle
14. Human and crew design — Put the person inside the system
15. Assembly and integration — Make many systems behave as one
16. Verification and validation — Prove it works for the mission
17. Ground systems — The spacecraft extends back to Earth
18. Training and simulation — Rehearse before reality
19. Launch readiness — GO, HOLD or NO-GO
20. Launch and ascent — Enter the mission
21. Mission Control — Gene Kranz and the mission lead
22. Crew, spacecraft and robot execution — Act in the world
23. Communications, navigation and telemetry — Let the world answer back
24. Landing, recovery and science return — Bring the mission home
25. Lessons and inheritance — Build the next mission from this one

Nine rails run through every stage

Authority, money, material, energy, information, safety, logistics, time and inheritance move through the mission at the same time. A space programme therefore behaves less like a single assembly line and more like several coordinated systems crossing the same sequence of gates.

The people lenses

• Judith Fan: make the relevant structure visible.
• Archimedes, Leonard Euler and Terence Tao: turn physical questions into mathematical structure.
• Karl Pearson: connect measurement to uncertainty and evidence.
• Alan Turing: ask whether the proposed procedure is actually executable.
• Fazlur Rahman Khan: ask what carries the load and whether the structure can scale.
• Gene Kranz: integrate specialists into a mission decision.
• Alan Shepard: keep the human operator and human receipt inside the system.

Mission intent → calculable world → buildable system → executable mission → world return → next mission.
