Hello everyone, 

Check out the amazing and creative entries of  the last challenge!

 

This week we have another theme for you: “Target Practice! " 

 

The holidays are over, and it's time to get back to work. Jebediah was gifted a wonderful little cabin during the holidays, he liked it so much he made two copies and put one on Minmus and one on The Mun.

But, Jebediah is a restless kerbal and an adrenaline junkie , and gets tired of too much leisure (ie: more than 5 minutes without any danger), so he decided that in order to get everyone's attention, he would build a rocket and launch it to try to hit as close to his cabin as possible.

 
Challenge Goal

  • In an unmanned vessel (ok, if you really want to kill somebody, you can), launch a rocket to either the Mun or Minmus, targeted at the cabin which is on each at Longitude 0, Latitude 0.
  • The goal is to impact the surface as close to the cabin as you can


Rules

  • The vessel can have two boost phases, the first to get to orbit, the second to inject it into an intersection course with the target. 
  • Once the boost phases are done, decouple anything you want, this will be the last time decoupling is allowed
  • Extra points if you do it all in a single launch. 
  • Even more points if it is a single stage
  • Download the save file from this URL or, use HyperEdit to move a target to coordinates 0,0 on your desired target planet.  If you do, the target cannot be bigger than 6m in any direction (6 of the M-1x1 panels).  As a reference, Jeb's cabin is 5x6m
  • All mods are allowed, except HyperEdit and VesselMover
  • Make sure that the target you are aiming for is selected as the target before impact
  • You are allowed to use SAS to point to the target, to make it easier to show on screen for the pics.  Just no thrusting of ANY kind (including stage separators) is allowed.
  • Post pics of the launch, interplanetary injection and either the moment of impact or just before impact.  Make sure that the target is shown, that way you will see the distance.  Note that the distance to the target will be shown even after the impact, if the target is close enough

Scoring

 

  • 1 point if you launch a rocket
  • 1 point if it leaves Kerbin orbit
  • 5 points if you enter the SOI of the target planet, not counted if you impact the planet
  • One of the following (whichever is higher):

- 10 points if you impact ANYWHERE on the target planet.
- 15 points if you impact within 100Km of the target
- 100-distance (in Km) from the target
- 125 points if within 1 Km of the target
- 150 points if you actually hit the target

Achievements

 

  • 1 point - I tried
  • 2 points - Lost
  • 7 points - Lost In Space
  • 12 points - Broad side of the Barn
  • 17 points - Outer Limits
  • 18-125 points - Marksman
  • 127 points - Expert Marksman
  • 152 points - Bullseye

 

We will have special badges for the first challenge of the year! Thanks to @linuxgurugamer for making this challenge possible! 


Share your screenshots, videos or images. We want you to have fun and share it with the whole community!

This post will be to summarize answers to questions, and to post a scoreboard once we have some entries

Rules Updates

  • Mods are allowed, but you must list all significant mods, including autopilots like Mechjeb.
  • Please provide a craft file for download

Answers to Questions

  • No trajectory corrections are allowed after the vessel is on an escape course from kerbin.  This include any kind of  force inputs of any kind, including things like RCS, decouplers, etc.

We can use the cloaking mechanism made by either @wasml or @Acea to make a true stealth missile :D.

you should also outlaw the use of mechjeb, since using that someone could hit the target dead center each try

Hmmm... don't think I'll be doing this one, I'm almost incapable of landing on the Mun even when I use the Alt+F12 debug menu...

On another note, how does one suggest what these challenges will be?

Nope.  Once the final burn is complete, no more burns

Actually, no force inputs of any kind, this includes decouplers, etc.

Even with Mechjeb, it's gonna be difficult.

But, I did forget to ask to list mods, I'll update the rules now, using mechjeb may be a different category

Send a message to @Darth Badie with the idea, be prepared to write up rules, etc

If it's a real stealth missile, then how are you going to know where it is impacting?

It occurs to me that this will likely be a game of luck due to floating point precision, but I'll try my hand at it.

Now that I think about it, even if the aim is dead on, the chance of destroying the cabin would be rather low, as the high speed could result in phasing through

Regarding the micro-precision needed to do a direct hit, yes, but otherwise, more of a timing/aiming issue

Alrigh, I did it :)

Still haven't figured out how to properly link imgur now. It used to be possible to see the pics right here in the post. Cant do that anymore...

Was a little easier than I expected.

These types of weapons are awesome to shoot. You haven't lived until you've been to the range with one of these big boys, though I haven't shot a 50. caliber yet, mostly 30. or 35. calibers. :)

Uhhhhhh.

I never fail to be amazed at what people will come up with.

I assume this is fired from space? So, girsy you have to get it to space, that is the boost phase.  Then firing it is the second phase.

No extra points but good luck with it

First attempt. I can do better.

Used MJ to start ascent because beauty mods and frame rates (nuff said).

ActnT5m.jpg

Disengaged MJ as Ap hit 80k - no circularization. Kept burning for intercept. First burn complete

biQtspv.jpg

Warped to change in SOI. That's when I discovered battery was dead. D'oh next time need solar panels.

No electric means no second burn. So close as it going to get one single burn:

There are mods which can predict the impact longitude and latitude...

I made about 50 attempts with a 5400 dV single stage missile without the assistance of any mods. It seems the precision required for a bullseye shot from the launch pad is not possible with the stock controls except for dumb luck. Well, I know it is technically possible especially considering exactly where the target is but, I cannot do it. I may use mechjeb and try again or I may just bow out of this one.

Sorry to say, that first burn is all you are allowed in this case because you are now escaping Kerbin’s SOI.  Ill allow a second burn if it is still fairly close to Kerbin, but no burns past that.

Imgur albums aren't working at this time, so your link was correct.  You can link individual images, but you need the direct link for that

I can't tell from the images, did you do any burns once you left Kerbin orbit?

That makes sense after reading it. In that case I suspect my dumb luck first attempt is about as close as I'm going to get,

Nice challenge this. I've done this the old school way, without mods (so all manual flying and no usage of mods to intercept the target).

Comin' to get ya boi.

First stage seperation.

In orbit around Kerbin.

Intercept with Mun achieved. I activated Commnet beforehand and deactivated the batteries, so I cannot control my probe anymore...

Which sucks, because I forgot to remove the manoeuver node......

Umm6Ay2.jpg

Carp. I don't think I'm going to be knockin' on Jebs door.

zm4w1V7.jpg

Well. That's it. 52km from Jebs shack. Gun get ya one day boi, but not today.

Points:

1 point for launching
1 point for leaving Kerbin orbit.
100 - 52 = 48 points for Comin' to get Jebby boi.

50 points for effort.

 

Thanks for giving me an excuse for procrastinating! :)

Can I use an indestructable probe core that's just a round ball (not a Stayputnik)? I want to leave a mark and you can't make craters in KSP

Here's my entry, "Impactor 3". No mods (at least none that make it easier)

Flight of the Impactor

9.6 km from the cabin - 91pts??

I'll link a craft file once I figure out how  here's the craft file Impactor 3

Here's my entry. I really thought I should have been able to get closer, all things considered. (Craft file)

Spoiler

 

(I had corrected some typo's, but they must have been undone at some point, Silly me was approaching edit burnout and didn't do a final proof-watch before publishing. I'll fix it tomorrow if I get time. Closest impact was actually 4.1 km )

Won't it bounce when it hits?

If you can assure me that it isn't bouncing, I'll consider it

So... Managed to barely get inside 1 km circle on Mun.

kOS for guidance and targeting. Maneuver nodes are overrated. UPFG rocks.

EDIT: Craft download (nothing to see there, really, everything interesting is in the scripting part): https://drive.google.com/open?id=16p_LpVSs9PQt1DHh_flXnZkxfl6_KqVs

It turns out that the giant space rifle is rather imprecise, firing at significantly different velocities on each attempt. If I do this it unfortunately will not be with the space rifle.
