After a slight paperwork mixup, KSC high command accidentally approved one of the ships Jeb designed himself.

He was pretty ecstatic.

Here he is on Duna.

And here's the return, the last stage of the rocket having accidentally exploded upon impact.

I documented and wrote up the whole journey here, check it out!

Edit: Per request, here is the craft file.

Computer Surgeon General's Warning: This is a 1284 part craft, with about 400 large parts to it. Side effects of excessive SRBs include lag, lag, and OH GOD THE LAG. Professional computer on a closed course, do not attempt.

Edit 2: I've been told the above link to the craft file is broken. Try this Mediafire link instead.

Per request, here is the craft file. I put a bunch of mission photos up in the imgur linked in my first post, I had some more that I'll put up tomorrow which mostly show more detail on the burns I performed.

That is incredible. You need a lot of faith in your design to let go of a burning SRB, I can't seem to drop spent parallel liquid stages without re-colliding unless I pack on a bunch of Separatrons. With a reentry decceleration literally off the charts >15g, though, Jeb is chunky salsa verde!

Oh my. 88 Launch clamps ? Do you have anything on how much it weighs?

As mentioned in the imgur, there are 248 large solids, 46 small ones, and six tons of parachutes. Neglecting clamps and struts, it comes out to 2140 tons. I'm afraid that Flight Engineer would die a horrible death if I tried to make it read the ship, so that's as close as I'll get.

I have literally never had the collision problem. Dropping burning SRBs is actually very safe, as it's only in vacuum, and the ship is no longer under thrust when it drops. So long as you don't do anything silly like start spinning around before you drop them, I can't imagine it going badly.

Greater than 15? Judging by the re-entry screenshots, I'm losing about five hundred m/s per second. Kerbals are made of some strong stuff.
