5:18. I made a mod with a custom engine based off of the SSME used as an engine. Specs were..... boosted.... (ISP of 9000, thrust of 5000 kN..... oh and mass reduced to 3.5 tons. you know simple stuff....)

Spoiler

I'll excuse myself now. This was purely for fun and I have no expectation for it to be actually entered/considered. If it does count though.... yay? I'll take that?

If you want a more reasonable unmodded entry...... I did make an actual non-modded launcher able to do it in 18 mins and 43 seconds. https://imgur.com/a/9bP4F0E

Imagine if the real RS-25 had those specs.........

16mins 44secs

A terrier...

...on a skiff...

...on 73 mainsails

20min 40 sec is as good as its getting as i want to throw my pc out the window

Wow... that was hard, but a lot of fun: not only getting something that would go fast enough, but also that didn't burn up on ascent, fall apart on staging (or just under acceleration) or go wobbling out of control and miss the Mun entirely.

Here's my time on unmodded 1.4.4:

At the top, minimal mass was the goal, using clusters of sepratrons on as little structure as possible.

Under that, a sort of vertical asparagus arrangement I thought should be called "fir tree" staging - but I guess it must have a name already.

Spoiler

And then... well, just MOAR engines and MOAR fuel tanks.  Extreme over-engineering at its worst.

Looks sorta like twisted candle staging. But not quite. Really not sure since on twisted candle, the number of engines per stage doesn't increase.....

I achieved it in the last minute.

18mins 48secs

 

Translation and summary :
I achieved KSP Challenge "Impact the Mun"!
I am pleased with it.
Thanks to those who taught flight techniques of KSP!

Impact at 20m 37s on my first try, with a 5-stager...
Not too bad on the part count and now I know what I did wrong.
See you again after breakfast!  


4 hours later:
Too much breakfast... too heavy to beat previous time.

hi @ryoji and welcome to the forums! 

that's a great time, congratulations!

18: 29. It is a satisfactory result.
Everyone's challenge and rocket are cool. Cheers.

This is the best method by far.

The only thing that could possibly be better is more engines.

[f_hiryu]

I also tried. 

15 min 48 sec

Very well done, indeed!

[mystifeid]

Could get trickier after this - 14min 59 sec. No mods. No clipping.

One Terrier on one Skiff on fifty-five Mammoths.

Taking screenshots interferes with staging

This is gonna hurt

woot finally right at 20min

Well done and I don't wanna rain on your parade but a second faster might have been good.

Impact the Mun!　　
Achievement of challenge I did it. 19min53sec (just barely)

[3SYUUME]

17m50s. It was a worthwhile event.

[purpleivan]

I had a crack at this challenge this evening and managed to hit the Mun in 17 minutes 2 seconds from launch... but just noticed the challenge ended 3 days ago.

Oh well.

Some pics of the journey.

 

Here's the video of the trip.

Don't tell me the challenge already finished. I just completed it in 14:29. I used only stock parts and KER. Aimed for about 5x TWR from start to finish.

Separation of sixth stage (last asparagus):

Eigth stage:

And final stage:

almost there

and final impact at 14:29

I assumed it had, as it was a weekly challenge, started 9 days ago.

14:29... for a while I thought I had the quickest trip

A lot of times, if a challenge is popular, and it look like this one is, they'll extend it to two weeks, so more people have a chance to participate.

@Darth Badie Is this challenge going until next week?

Hmm. You'd need to average 10000 m/s in game to impact the mun (if I calculated correctly) on 20 minutes in game time. That's not impossible...... Difficult yes impossible not really. 

I used to not know how to orbit, so to get into escape trajectory , I went 3.75 suborbital 'till I got to 30 whatever m/s. So it's just a hopskipjump to 10,000, right?

Um, nevermind. Just did some math, I'd need an insanely tiny lander/impactor and old KSP aerodynamics.
