The Fifteen To One

The Fifteen To One.

Fly to the Mun on 15 tanks, land, then return on only one? How do you rate your chances? (stock)

Sometimes you need to make every drop count, and still pull off feats that keep space exploration in the public eye.

On top of the Daisychain fuel system, already widely regarded for helping squeeze the last ergs of Delta-V from any

rocket, and for helping prop up Kerbins sewerage and garden hose industries, comes a brand new design innovation.

! Droppable engines !

Everyone knows a lighter rocket is a more efficient rocket, now you can add instant lightness by throwing those heavy old engines away.

Despite having even less fuel than the Stocket Pocket Rocket, the Fifteen is so light that in careful hands it\'ll have even more in reserve for on-orbit maneuvers.

Now available in both regular and RCS flavours from the factory.

Ship files after the pics, have fun flying

I have now updated the Fifteen to work in 0.14 without parts rearranging themselves in the VAB.

15 you say? Try 10.

.craft, please?

I must bow to the master it seems, may I have the craft file?

This is the 10 tank mun lander. Fuel is extremely tight, so there isn\'t much room for course corrections. This is how I did it:

1. Launch full throttle straight up

2. Bank east 20 degrees at 11000m

3. Drop outer tanks when empty.

4. Bank flat east from 20000m-40000m

5. Cut engines when apogee is ~72000m

6. Full throttle when near apogee for circular orbit dropping inner tanks when empty.

7. Initiate TLI as soon as the mun rises from the horizon reaching an apogee of ~12Mm

8. Retro burn for orbit of ~20000m around mun

9. Retro burn for landing

10. Use ASAS and engine to lock craft straight up while tapping lightly on controls to scrub all remaining horizontal velocity.

11. Burn east until ~800m/s parallel to orbit of mun

12. Correct apogee to inside atmosphere

13. deploy parachute and burn engine near ground for gentle landing.

When ASAS is on the lander responds very well to controls still, making it easy to precisely maneuver.

Wow, if I were lucky I would probably only manage to get into a pretty bad Munar orbit. Good job flying it to the Mun and back.
