  1. Sorry about the zillion images, I've been at this for a while, it seems. Back in version .90, I build a Kethane-mining ship that could fly from anywhere, to anywhere. NoNo, that's not it. My fully-equipped Munar base, with multiple relocatable base units, uncrashable rovers and personal escape pods? How about the Modular 1.2 *million* ton orbital station? (image shows one of 15 modules, undergoing ground testing) umm, Solar ion glider? flying soccer city? ( Steam-powered Kerbin Circumnavigation? Lawn chair holiday to Eeloo? nope, thats not it either. I KNOW!!! Its my *Grand Experiment* on the Migratory Habits of the Octo-2!
  2. Ok, Ive done it. Start science only, a multi-tier wedding cake of Fleas with thermal-structural decouplers, and a **lot** of retries. Things I learned: *Structural member is a good decoupler, but a bit heavy. *Angled fins on capsule are essential for spin stabilisation during reentry, but they are a slight problem for rotational stability during launch. Adding a counter-angled fin one stage lower is not a complete cure for this. *If you spin rapidly enough, and you have an expended flea pointing into the wind, you can survive reentry just fine. (rapidly enough is on the order of 2000 rpm.. no idea how Jeb syrvived that!) *When using structural member for launch, launch *gently*.. A 9-tier wedding cake of a rocket will not appreciate the aero or gravity forces of a rapid launch. Disclaimer: The images in the album are representative, and actually sampled from many, many, many attempts. Sequence may be off. Max altitude is the best i managed to survive from. I reached much higher, but died due to non-reentry, or too steep reentry. Many Many deaths. so sad! Achieved: 859101.3m alt Achieved *almost* orbit.. After using allowed jetpack fuel, I was in a 859.1kmx61km almost-orbit.
  3. I still have to see even one entry that fulfills this ridiculous entry rule, none of the above entries do. Note : Be completely safe with redundant landing and abort systems. This means you need *at least* two separate, independent launch abort systems, and at least two separate independent landing systems, that are capable of functioning safely even if the primary abort or landing system fails. . To see if your vehicle is "completely safe", try this simple experiment. At 30 seconds after launch, switch the engine off. Can you safely land your passengers without switching the engines back on? If the answer is no, you have violated rule#4. Landed them safely? Ok, great! Now launch again, and switch off the engines at 30 seconds again. You may NOT use the same method for saving the crew. (*redundant* abort systems, remember?) Now land them safely, again. *redundant* abort and landing systems are very, very, very, very hard to do.
  4. NoNo. a Bunny-hop to 250km is not how you retrain Flattards! Launch them to orbit. THEN ask them how much they are willing to pay you to get them down.
  5. Conceptually, reasonably easy. A 3.6 ton ion drive rescue ship (that's mass in high Kerbin orbit, about 1000km!) Burn prograde with kerbin orbit, head out to the deeeeeeep reaches of space: 3600 m/s Wait 9 years to get to apogee. U-turn, 1830 m/s 9 years later, intercept Res-Q vehicle. Intercept requires 4200 m/s To return, you basically reverse the procedures.. 4200 m/s prograde burn. 1830 u-turn at distant apogee this bring you to an atmospheric meeting with Kerbin at mission time ~ 36 years, and a velocity of some 5.5km/s As my vehicle is nothing more than a command chair on an octo, on an Ion Drive, I chose to use propulsive braking rather than aerodynamic breaking. a messy 6000m/s of burn later, my pilot is safe in a 100x100 orbit around Kerbin. The launcher is a very simplistic thing, just a can and some 'chutes on a Vector. Serves as launch-to-1000Km, and also many years later as recovery-and-landing vessel. Below is the Rescue ship. busy dropping droptank 2 of 5. It is just about out of kerbin on its way to deeep space. And this is the sort of orbit you need to play with, to make the u-turn cost effective. Know what was my biggest obstacle? Getting the power needed for that single ion drive, while at 4x Eeloo orbit distance. it. re.qui.red.a.lot.of.pat.ie.nce.and.st.op.and.st.art.of.the.ion.dr.ive. Next time, I'll sacrifice another 2000m/s of delta-v (i've got plenty to spare, total load is over 26k), and go much less far out. And yes, maybe next time invest in some RTG instead, to heck with the cost! This one weighs in at 123846 cost, and masses 63.4 tons (of which 60.5 tons is launcher/lander)
  6. 300 or 400 should do. Also, remember to run your trip from Earth to Mars, not from Kerbin to Duna. Realism overhaul, including Real Solar System is a must. Remember to include TAC life support or something similar. No nukes allowed. No Ion drive allowed, unless you nerf them down to realistic thrust (about 1/1000000 of current game levels)
  7. OOH, landing speed, **MULTIPLIED** by max passenger count? Flying Soccer City My flying soccer city lands at 12m/s, houses 1841 kerbalnaughts, and uses only 60 parachutes. That should be good for 12 * 1841 - 6000 + 100 + 500 points? (16692 total) If this flying abberation qualifies, i will record a fresh set of images showing the safe landing etc...
  8. Ok, maybe I'm stupid, but I fail to see the challenge? Its just a Twin Boar, command seat, and Val. I fuel-cheated to fly it to orbit, then uncheated and landed it. Could have got it to orbit the hard way, but that didn't seem needed...
  9. Ummm... ISRU allowed? It should be possible to build a SSTO, Load it 90% full of fuel. Fly to orbit. ISRU probe flies to Minmus, mines, flies back, refuels SSTO. Repeat as needed. Flies to Minmus, refuels itself, flies to MoHo. (possible detour via Gilly if you feel it worth it) Refuel itself on MoHo, back to MinMus Refuel to brim. Back to SSTO. Dock, return to Runway. Recover MORE than you launched with. Tedious, but should be doable... Will I do it? nah.... But allowing ISRU on a pure economy run opens your scoring to exploitation.
  10. Maybe you guys use a better ascent profile, maybe my KSP is a slightly differing version than yours. Basic lifter, with a bit of throttle control on the core, gives me payload on orbit of 27.1 ton Basic asparagus, same design just with fuel feed, give payload = 29.9 ton Asparagus with droptanks before dropping the outer engines, gives me 31.1 ton I wouldn't call an increase of (29.9-27.1)/27.1 = 10.3% in payload, simply by toggling crossfeed, to be a bad deal at all!? With almost no added cost, just some complexity, i'm able to increase the Payload by 14.7% You yourself achieve a 7.1% increase in payload.
  11. The correct way to replicate the Constellation spacecraft: * Draw up elaborate plans for a spacecraft. * Modify, re-modify, and re-re-modify your plans * Now spend 17.3 earthly Fortunes on the projects * Launch one token simulator of the least of your designs, then call it quits. * 10 years later, rename your system SLS, and get ready to spend another double-handful of Fortunes on it. * Tell everyone it will be ready in '16. erm, '17. make that '19. maybe '21
  12. Oh goody, a two-part challenge! Part one: Figure out just what the OP is saying in that wall of text Part two: do it.
  13. Tried for 5G, but it seems to be out of my reach. The is my *5G* design, doing a 3G ascent to orbit with the greatest of ease. Leftover delta-v in excess of 4 km/s http://imgur.com/a/IegfQ
  14. This challenge is bad for my health. The basic rocket design is easy enough, it just needs a lot of stages, and a lot of parts. So many, that my launch framerate drops to 1.2 MPF * Why is it bad for my health? The smoke coming off my graphics card is bad for the lungs, is it not? * MPF = Minutes per Frame.
  15. WEEP! WAIL! Beware all ye faithfull, for the devil is among us, and his name is ManEatingApe ! This miscreant doth defy the very laws of fizzics, yeah I tell unto you my brethren, he invokes the very Kraken Himself with his blasphemous ways!! There are thing that no mere Kerbal can do, indeed things no Kerbal dare *dream* of doing, yet this ManEatingApe not only dream, not only does, but then goes forth and **spreads the word** on how to violate the very fabric of Kerbality Repent and turn away from such Witchcraft!
