M3: The Minimal Mass Mun Challenge

[bitzoid]

Build the lightest single-trip craft that can land on the Mun.

Rules:

• Build a stock ship (no mod parts, stock physics). Crewed or uncrewed.
• Land on the Mun.
• Nothing may explode on the surface of the Mun.
• No ion engines.

The goal is to minimise the (wet) mass.

Highscore:

• 1.32t by Kergarin

Are Kerbal's required? Is a return to Kerbin necessary?

No and no. I'll add this to the description.

(Generally speaking I hold the view that if a challenge does not specify something it can be interpreted however you like. This adds a margin for "clever" things.)

Then 2.205T, which I'm confident can be optimised further given that I landed with 700dV left in the tank...

EDIT: 1.98T via further optimisation. Landing is tricky since one of the "optimisations" was to remove the reaction wheel, but landing on gimbal alone is possible...

1.565t with ~200m/s left. There still goes more.

This challenge seems to lack pictures 

[Kergarin]

1.32t with 9m/s left

I intentionally didn't post one in order not to spoil the original challenge. I'll add a highscore for everybody who posts a picture of the design. Because pic or it didn't happen

Would a Video work too? 

seems I did save some more fuel this time. Still far from perfect...

Edit: I wonder where else I can go with that
