Lift a satellite to Keosynchronous orbit.

[Entroper]

This is similar to my low orbit supply delivery challenge. The goal this time is to place your cargo stage into Keosynchronous orbit.

Your score is determined by the mass of the satellite that you can deliver to Keosynchronous orbit, and the cost of putting it there and returning your Kerbals safely to Kerbin. The satellite can be anything -- a cluster of fuel tanks if you wish, or a custom part that you made -- but if you use non-stock parts to lift the satellite, or to return your Kerbals home, you must note this with your score, along with the custom parts that you used.

In order to score any points:

• 
  [li]You must return all three Kerbals safely to the surface of Kerbin. They can be in the ocean, they can be on land halfway around the planet from the space center, whatever, as long as they touchdown safely.[/li]
  [li]You must jettison a separate cargo stage to an orbit approximating Keosynchronous orbit (the more accurate you are, the higher your score), which is

2 868.4 km. No rocket engines may be attached to this stage. You can attach RCS engines and fins to this stage, but their mass will not contribute to your score, and any partially-used RCS fuel tanks will count as zero.[/li]
[li]The cargo must be delivered as one unit; it can\'t be separate pieces drifting apart. If you have multiple pieces, count only the largest single piece.[/li]

Scoring:

[list type=decimal]

[li]Your score is the mass of the satellite delivered, divided by the cost to place it into orbit, minus your eccentricity factor.[/li]

[li]The mass of your satellite is the sum of the masses of all the parts that make up its stage, minus any decouplers that attached it to your rocket. Any fuel tanks that are not 100% full count as zero. One mass unit = one million points.[/li]

[li]Your cost is the total cost of all ship parts, minus the cost of the satellite stage (your clients paid for that). Include any parts used in the satellite stage that have any active role in the rocket, such as fins, RCS blocks, SAS units, etc.[/li]

[li]Your eccentricity factor is the difference between your apoapsis and Keosynchronous altitude, plus the difference between your periapsis and Keosynchronous altitude, just prior to jettisoning the cargo. Rounder orbits are better, and orbits closer to the target altitude of 2 868.4 km are better.[/li]

[li]Final score = cargo mass / cost - eccentricity factor[/li]

[Entroper]

My 'satellite' was 7 LFTs and 7 SRBs, for a mass of 30.1.

My cost was 93 097 (same as my low orbit supply ship, with a smaller payload).

Apoapsis 2868.4, Periapsis 2865.5. Eccentricity factor = 2.9

Score: 320.4 points

I\'d be all over these types of challenges, but I\'ve done so many balancing .cfg edits to the parts I\'ve loaded that I probably can\'t list them all off the top of my head...
