1. The Martians outfit an expedition to journey to the Asteroid Belt.

2. The Asteroid Belt is located just outside the orbit of Mars.

3. The mission path takes it to a candidate asteroid.

4. Nuclear detonations are used to 'nudge' the candidate asteroid into a new orbital path.

5. The asteroid's new 'orbit' will take it close to Mars.

6. Another series of nuclear pulses decelerates the asteroid relative to Mars.

7. The asteroid has assumed the orbit of the Moon of Deimos.

8. The asteroid is split into two main parts. The smaller fragment is Deimos, the larger is Phobos.

9. An electromagnetic mass driver propels the 'Phobos Fragment.'

10. The mass driver has a power station (nuclear fission?). Scoop vehicles strip the surface of loose material and then gouge out additional material as reaction mass for the mass driver.

13. Under mass driver propulsion, Phobos spirals in toward Mars. Actually, the journey would take numerous spirals; only one spiral is shown here for simplification.

14. Phobos is in place, completing the Martian Moon System as it is today.

15. The large crater 'Stickney' could be the site of the nuclear detonations.

16. The lack of dust and the presence of grooves on Phobos could be the work of the mass driver reaction mass scoop vehicles.
