The Retro Solar Rescue
Big thanks to @cratercracker for making the artwork above.
The challenge sounds very simple:
Save Burberry Kerman, who is stranded in an orbit around the sun.
"What kind of Orbit?" you may ask ... Well, it's nothing fancy: An orbit between Kerbin and Eve, nearly circular, at 180 degrees inclination. Just sign this contract and off you go!
See here, how he got there:
Don't worry, you don't need the Goliath to get into a retrosolar orbit, you
Burberry Kerman splashed down in the ocean tonight!!
After mastering the art of gravity assists, KSC was able to pull off a 103 years and 294 day long mission to rescue him. They even could have left a entire stage with a Kerbodyne S3-7200 tank (2944 m/s) at home.
The short story:
dV: 5219 m/s
Mission time: 103y 294d 05:36
Route: LKO - Eve - 2x Kerbin - Jool - 2x Eve - Jool - Retrosolar - 2x Eve - 9x Kerbin - Rendezvous - 4x Kerbin - 7x Eve - Jool - Prograde - Kerbin
