homeward bound challenge

[flytandem]

It's been a while so I thought I'd toss out a challenge for those interested in a bit of fun. The deltaglider has plenty of fuel to make it home to a landing on Earth if done right. No refuelling, or creating other ships to drag it home. Slings and atmospheric usage ok. Must be back on Earth within 2 years.

BEGIN_DESC
You have 2 Earth years to make a safe landing anywhere on Earth.

Solution: Imagine a skier or boarder carving a nice turn around a pylon. Same thing is available using Mars. Fly (gliding) inverted around Mars and exit at the right time and velocity and you will be on your way to coast back to Earth. Two part youtube of it is below.

(setting up the aerosling)

(flying it)

Very nice challenge, flytandem. I was hoping to see what I could do with the challenge using IMFD so had a look at it last night. My first attempt required too much dV even with the sling so I'll have to spend some more time thinking about it rather than just winging it.

I'll see what I can do once I have some time and post my results. Or if someone else has done the challenge with IMFD I'd be interested in seeing the plan.

If anyone wants to try a similar challlenge but without having a solution posted then here is something.... as you probably will figure out you need to aerosling off Titan to head to Rhea to insert an orbit at Rhea.

BEGIN_DESC
Insert an orbit around Rhea without refueling.

Oh well. Even with your great video walkthrough of the plan you used I haven't had great luck in a couple more attempts with IMFD. I'm sure the problem is the operator and not the tools. It seems more difficult to setup a multi-part plan with IMFD than with TransX. Sorry, no good information from me on this one.

I would be interested in hearing what kind of plans others might have developed using IMFD for this challenge.

Thanks again for posting the challenges, flytandem.
