Out of gas

[Jeb x Valentina]

Jeb wanted to take a break from all of his work and decided to invite bob, bill and val to a barbecue, they accepted. But when jeb arrived home, and tested the grill, he discovered it had no gas, and he didn't had time to go buy more,  so he ran to the VAB, grabbed all of the liquid fuel tanks (rocket, jet and xenon),  dismanteld them in his junkyard, compressed them into grill gas, and put the fuel on his grill;  he had a nice barbecue, but the KSA discovered there were no fuel tanks next day, only monopropellant and SRB's were left, and they promised to launch a rocket to the mun that day!  Your mission: Getting to the Mun using only Solid fuel boosters and monopropellant. 

Normal: Get to the Mün, plant a flag, and getting back using only SRB's and monopropellant

Hard: Same, but without monopropellant

Bonus mode: Hard mode, but Minmus

Legend mode: Surprise me!

 

Rules: 

1. No cheats! (Part clipping, Cheat/debug menu, Kraken drives, mods, etc)
2. No liquid fuel, jet fuselage, nor xenon is allowed for this challenge, only Solid fuel and monopropellant (On hard mode and Bonus mode use only Solid fuel)
3. No expansion DLC
4. You must plant the flag and get back to kerbin, if you don't plant it, you don't completed it
5. The ship must be manned and the kerbal must survive reentry
6. you must land, if you crash it doesn't count

 

You Must send a video of the mission, good luck kerbonauts!

Are mods allowed? Near Future Spacecraft add some pretty OP monoprop engines with thrust of liquid fuel engines, and efficiency of nuclear engines. I'm talking 2000m/s, maybe even 3k with a Mk3-1 command pod and smallest fuel tank

[imcute]

i can do it with xenon electricity and no monoprop or solid fuel(overclocking dawn engines are hard but would work under careful throttling)(to the mun and minmus and back)

[imcute]

wait just found out that there is an engine that uses monoprop

i can do this then

[imcute]

well i cant post images by pasting so my screenshots wont work

i swear not to cheat

[imcute]

(i think that its easier than mun due to easiness of soft landing) bonus mode with monoprop and additional mun visit

[imcute]

i give up

monoprop engines make the craft tumble even when its perfectly balanced

[Poppa Wheelie]

I've done this challenge with Monoprop only here:

But I've never tried SRB only, so I thought I would give that a shot.  So here we go, SRB only, no monoprop.

Liftoff to LKO

Spoiler

Liftoff

Drop the booster, and blow the fairings

Finish the orbit at the Ap

Transfer Burn

Spoiler

Almost one orbit later, begin transfer burn

Half way through transfer burn

Transfer burn complete

I got this very straight Mun approach (great for suicide burn attempts), and didn't have to use any of the Sepratrons I had planned for.  So I'll use those on the landing.

Mun Landing

Spoiler

Approaching the Mun

Begin here

Drop the last spent Hammer, and fire 3 pair of Sepratrons

Eject the Sepratron ring strut

Burn a Hammer

Burn 3 pair of Sepratrons

This sequence took several tries.  I either had too much speed and hit the ground before the last Sepratron pair finished, or I reached 0ms at too high an altitude.  I could have done it a few more times and got it just right, but on this particular sequence, although messy, I got it to work without breaking anything.

We're moving at 34.7m/s right before touchdown

The vehicle touched and bounced two or three times

Finally touched down, with no further bouncing, but started rolling down this hill

Rolling finally stopped

Flag

Spoiler

Val plants a flag

Val admires the view

Val reboards

Return Burn

Spoiler

Before liftoff, we deployed the solar panels to recharge batteries.  Solar panels stay deployed.

Liftoff

After a little bit of trial and error, I determined that a 28 degree pitch would do the trick

Hammer got us this far

Six pair of Sepratrons got us this Kerbin Pe of 24,976m

I turned retrograde and ejected the spent Hammer and Sepratrons

This raised the Kerbin Pe to 30,450m

Reentry

Spoiler

Mun and Minmus as we near Kerbin

Stow the solar panels

Reentry begins

Passing through 34,900m ASL

21,585m ASL

Chutes partially opened

Chutes fully opened

Splashdown

Ready for recovery
