Hello everyone, Sometime around version 0.20 I developed an unhealthy obsession with big, reusable interplanetary transports. These are massive ships with enough delta-v to go pretty much anywhere and back. Once in space they can never return to the surface but rather ferry packages from Kerbin to wherever and back. I've named all of them after the Clipper ships that used to sail the tea routes in the 1800s. Here's an example, currently I have the Clipper Houqua II speeding on it's way toward Jool. Leaving Kerbal it had a mass over 450 tons and carried seven separate mission payloads on her seven docking ports: 1) A (24 ton) habitat and extra fuel module with the Tsartier Space telescope attached. This module can also serve as a lifeboat... This is currently in that position to balance the Vall Lander on Station 7. It will return on the center position. 2) Clamp-o Jr port with a remotely flown glider packed with instrumentation. (1.8 ton) This will be used for atmospheric flights in Jool's atmosphere. 3) This is the nose of the ship, it has an (8 ton) orbital telescope which will be dropped along he way to Jool and establish a permanent orbit between Jool and Duna. 4 and 5) Identical landers for Bop and Pol (19 tons each). 6) a remote pod which will descend by parachute into Jool full of instrumentation. (1.3 ton, this counterbalances the glider with some adjustments to the crew module) 7) the (26 ton) Vall lander. Obviously this didn't all go up at once. The Clipper was launched (let's not count how many times) and used most of it's fuel getting up there. All the packages were launched and docked, these doubled as refueling and crew transfer missions. This package is speeding along with two others, disposable Laythe and Tylo Landers. All landers will land, take all science data possible and have enough delta-v to rendezvous with Houqua II in a parking orbit around Jool. The Clipper has an on-board lab for processing data. Each lander also has a detachable Materials Bay with Goo that will dock back to Houqua and can be returned to Kerbin via parachute. The remains of all the landers will be deorbited into Jool and all Kerbals returned home on the Clipper. I'll let you know if any of it works... I have pulled off a similar (but much smaller) mission to Duna with these Clippers. If anyone wants I can post a pic, I've actually been meaning to start an entire thread to see if anyone else is building similar ships. I still need a post or two before I'm allowed to post pics or my ribbons. My build style: 1. Very few mods, Engineer, Mech Jeb, the occasional telescope or science gear but stock engines, stock fuel and I have to get it up there the hard way. 2. I go for as much realism as possible and this means lots of nose cones getting jettisoned before circularizing. On the pad its got to be aerodynamic, once in orbit, form entirely follows function. 3. No intentional one way missions. 4. No Kerbal left behind (although I must admit, we didn't find much of Bill. We did put a flag on the spot on Ike where his extreme eva ended... abruptly). 5. No zombie kerbals. When I upgraded to v.23 I had to kill Bill. Sorry buddy. 6. Reverting to launch or VAB is fair in my book prior to launch but after I hit the spacebar, whatever happens counts. Most of my designs have fairly elaborate Abort sequences. If I'm not 100% confident it gets a remote launch with a Kerbal to follow in a transfer vehicle. 7. No space junk. I like my solar system tidy so everything that goes up must come down. Somewhere. Apart from permanent stations and telescopes. 8. There is no such thing as too much RCS fuel. 9. There is no such thing as too many batteries. 10. On anything remote, add at least 3 of the fixed solar panels for luck. It's a real bummer to get a probe all the way to Eeloo just to watch it sail by because Jeb forgot to extend the panels.
