EVA to Orbit Challenge


Recommended Posts

After crashing on the Mun, Bill went to see if he could EVA to orbit. And he did!!!

Rules:

  1. All planets are allowed except for gas giants and Gilly. Atmospheric Planets are fine and good for attempting to get nowhere IMO.
  2. You must reach orbit from the surface without cheating with only the Kerbal., and then attempt (but don't have to succeed ;)) rescue the kerbal with a brand new craft without cheating. (In my example the Kerbal crashed into the Mun with the rescue.)
  3. No mods that alter physics allowed. 

Scoring:

The points modifier is as follows:

g'sASL3 x (PE+AP) rounded to nearest digit. (give me something better if you want ;) )

This means that I got 72902 89 points.

(gs-ASL is the brackets in: 

Surface gravity 1.69 m/s2 (0.172 g)

in this case 0.172g for Eeloo

My attempt:

Leaderboard:

Mun:

  1. RA3236 - 89 points

Minmus:

  1. @zarakon - 5045 points, bonus because of a double escape.

Ike:

  1. .

Dres:

  1. .

Pol:

  1. .

Bop:

  1. .

Eeloo:

  1. Nefrums, 274p and also added this leaderboard to the OP!!!

Other planets (username, planet and approximate delta v to reach orbit. I'll check this:

  1.  

Special mentions:

@Chemp

for his amazing Kerbal-powered rocket that sadly broke the rules of only having one part (kerbalEVA).

And a badge for those guys who like badges:

Good luck!!!

5.00-remaining EVA propellent x g'sASL x PE x AP/1000 (give me something better if you want ;) )

g'sASL^3 x (PE + AP)/1000

Remove the remaining EVA propellant as a factor as remaining fuel can be used to increase PE/AP, sum AP and PE, and increase the weight of the G.

First off, your challenge - your rules. But out of curiosity (and with an evil plan in mind): is there a reason you ruled out atmospheric planets?

 

Usually atmospheric planets have gravity and need more than the delta v of a jet pack and a RT-10 'Hammer' SRB. I'll change them so that you can try if you want, but I think it'll be a pretty lousy attempt.

Why do moons when you can do planets?  :D   261p from Eeloo!

I also made a small test of how much dV you can get out of the EVA Propellant.  I got 634,3 m/s

 

Hmm. Not bad. 274 points though, unless I'm mistaken. Good job, added new leaderboard to OP.

0.005^3 * (19,210,500 + 13,147,500) = 4045  :D

 

If you're going to ban Gilly for the ability to escape orbit, then Minmus, Pol, Bop, and maybe even Ike should probably get the same treatment.  Of course then that only leaves Mun, Dres, and Eeloo as possible locations...

Well, I told you I had an evil plan. Here it is: To orbit from KSC, no engines, no rotors, nada. Just a Kerbal carrying a little construct with a ladder to space.

Body: Kerbin (1g); AP: 132700m; PE: 80500m 

1g3 * (132700+80500)=213200

I admit I made a very loose interpretation of your rules, but, but, but...

Feel free to disqualify my entry for making my Kerbals slave on a treadmill :D

A question. Can we use planets from mods, or do they have to be stock?

You'll have to give me the planets name, planet pack and gsASL, as well as the highest point on the planet for reference.

What the!!! Escape velocity from Kerbin, meaning 4045 plus 1000 for double escape. That's 5045.

You'll get a special mention on the leaderboards. I really need to know how people do that...

It works like this......

In KSP,the animations of Kerbals are irresistible forces.  if the active Kerbal and any non-terrain object (a ship/base/rover or other Kerbal) would occupy the same volume of space, the game gives priority to the active Kerbal, and he will push everything else out of his way to do the full range of motion of his animation.  This can lead to disaster if your Kerbal somehow falls down and slides under your base, and the base doesn't have enough ground clearance for the Kerbal to stand up.  If you stand the Kerbal up anyway, he will stand to his full height, catapulting the base into the air, no matter how heavy it is.

However, this effect can be used as a form of propulsion.  The most common method is to build something with a short ladder on it aligned with the desired direction of travel, and with some sort of walls blocking the ends of the ladder.  Thus, when the Kerbal climbs the ladder, his animation makes either his head or is feet collide with and push against one of the walls at an end of the ladder.  The animating Kerbal pushes the wall out of his way.  Because the wall is connected to the ladder, the ladder is dragged along with the wall.  Because the Kerbal is on the ladder, he's carried along as well.  And if you continue making the Kerbal climb the ladder, the Kerbal continues pushing against the wall, resulting in a continuous application of force and thus acceleration.

Various things limit the utility of exploiting this, however.  The force applied by the Kerbal is proportional to the speed he moves during the animation.  Fallen Kerbals leap to their feet so can toss heavy bases around no problem.  However, Kerbals move slowly on ladders, and once the ladder-powered craft is moving in the same direction, the net force applied per collision by the Kerbal becomes lower and lower.  As a result, ladder-powered vehicles have to be pretty small and light, especially if you want to fly vs. rove or boat.  So you can't build a viable space program around this exploit, but you can make handy little personal recreation vehicles, roughly analogous to kayaks, bicycles, and ultra-light aircraft.
