Is mining/ISRU allowed?

Here's my first SSTE: Sotka I More pictures in the imgur album: The vessel has one Vector and two NERVs, and no air-breathing engines . It can reach LKO in single stage and land on Minmus comfortably for refuel. It can reach and land on all bodies (expect Eve). The cargo bay holds liquid fuel tanks, reaction wheels, batteries, ISRU, radiators and and an RTG (see imgur album). It can land on most bodies with just NERVs and has plenty of dV when fueled only with liquid fuel (see tables below). The two airbrakes on top of the Vector also double as heat shield when performing aerocapture/brake. When out of fuel, it will tip on its tail and won't be aerodynamically stable. Having the front C7 adapter full (locked by default) will prevent tipping and keep the CoM in front of CoL (see imgur album). Basic info Mass: 79,907 Liquid fuel: 5,900 Oxidizer: 5,060 Cost: 106,265 dv in LKO: ~1,700 m/s dV profiles Lf Ox Mass Thrust dV Full 5,900 5,060 79,907 1,120 4,888 Lf+Ox (Vector) 4,140 5,060 71,107 1,000 3,137 Lf only (post Vector burn NERV) 1,760 0 33,907 120 2,357 Lf only (NERV) 5,900 0 54,607 120 6,096 Selected TWR stats Lf only profile Full Min TWR Max TWR Min TWR Max TWR Moho 0.81 1.77 5.19 11.55 Kerbin* 0.05 0.11 1.23 2.74 Mun 1.35 2.93 8.60 19.14 Duna* 0.71 1.54 4.72 10.49 Laythe* 0.14 0.30 1.63 3.63 Vall 0.95 2.07 6.08 13.52 Tylo 0.28 0.61 1.79 3.97 Eeloo 1.30 2.83 8.30 18.47 * Atmospheric Scoring Mass: 79,907 Kerbin SSTO: 0.95 Bodies: 0.8 (all bodies except Eve) Moho-in-one: - (I haven't tested this yet. Might be possible) no worries ISRU: - (Drill-o-Matic Junior needs at least 2,5 % ore concentration) it's good for something - (good for nothing) short transfers: 0.8 (transfer burn to Jool in less than two minutes, but needs Laythe's gravity and atmosphere to capture and land) quick start: - (a good pilot might be able to get to Gilly or Ike, but I didn't try) part count: 0.9 (67 parts) VTOL: - Multiplier: 0.5472 TOTAL SCORE: 43.73 Getting to Tylo Refuel on Bop or Pol and fill the C7's only with liquid fuel, giving you 1407 m/s for the NERVs. Lock all tanks with Lf+Ox. Use NERVs to transfer and capture to Tylo. In Tylo SOI unlock Lf+Ox tanks, giving you 2793 m/s for the Vector to circularize and land. Suggested Jool-5 sequence Laythe-Vall-Bop-Tylo-Pol

Is it allowed to assemble the craft in orbit before landing on Eve?

Here's my submission with a 136-seat SSTO to Eeloo (and Minmus). The video was published already in last August, but that's still okay, I guess? Craft info: mass: 915.06t cost: 924,876 crew: 136 Craft file available on KerbalX. Mission info: DeltaV on LKO 4,874 m/s Eeloo reached with Eve-Kerbin-Kerbin-Jool assist Returned to Kerbin with Jool+Tylo-Kerbin-Kerbin assist Minmus visit not originally planned Unpowered landing to KSC Here's a link to an earlier post:

@sdj64 Thank you for accepting my submission and also for the feedback! I'll keep this in mind the next time. The "bridge" actually does produce drag, and it's not the most efficient place to put the crew in. A mk3 cockpit in place of the current nose cone would have been a better solution. But hey, it's "Kerbal Space Program" not "Sensible Space Program".

Here's my 3rd level Jool-5 mission in the form a video. I hope it's enough, but I can make a more detailed image album if necessary. Flown in KSP 1.3 Mission info: Single launch stock SSTO with full part recovery. No refueling or ISRU needed. All moons have separate landers, and the Tylo lander uses an Ion Tug for transfers. Landers are packed in one long + one short Mk3 Cargo Bay. Mothership separates from lifter in LKO and continues to the Joolian system. Straight transfer to Jool without gravity assists. All landers (except Laythe Jet) separate from mothership in Jool SOI. Laythe's gravity used to capture to Jool and transfer to the moons. Landers return to mothership in Laythe orbit. Straight transfer from Jool to Kerbin, where orbit is achieved by burning retrograde (~1.1 km/s) and aerocapture. Once in circular LKO, mothership unites with lifter. Mothership has no RCS, so final docking is done with the lifter. A crew of six Kerbals with one for each moon and one for Ion Tug. Four are in Mk2 Crew Cabin, one in the Jet and one in the Tug. Ship cost: 411,089 Mothership delta-V in LKO after separating from the lifter: 4,353 m/s Link to craft file in KerbalX: Vellamo I Visual mods: Environmental Visual Enhancements Distant Object Enhancer KSPRC Terrain textures Rareden's Real 8k Skybox Scatterer Spectra Visual Compilation Spaceplane Corrections Texture Replacer Replaced WindowShine Gameplay mods: BetterBurnTime BetterTimeWarp EasyVesselSwitch Kerbal Alarm Clock KerbalEngineer PreciseManeuver TransferWindowPlanner HyperEdit (not used in the mission) MechJeb (not used in the mission)

Here's my submission with Sirkka I ("Mini SSTO" in the video): 16 parts single rapier engine 2 ramp intakes mk1 inline cockpit mass: 5.04t cost: 14,116 crew: 1 Landed at KSC from orbit without using engines, although had a tiny bit of liquid fuel left Score: I don't which landing modifier I should use. If its 10 (land it back at KSP under power), the score would be 5557.1307 = 1 * 14116 / (5.04^2) * 10 I hope video submissions are ok. There is a small discontinuity when landing (at ~11 km), because I couldn't nail the landing on the first try , so I had to quick save + load.

Here's my SSTO to Eeloo with some passengers. I hope you guys enjoy. For mission planning and getting that K-E-K-K-J transfer, I used Flyby Finder and followed @PLAD's posts about Eeloo and Jool (without Mun assist or Jool aerobrake). For Kerbin ejection burns I used Precomputed Low-TWR Interplanetary Transfer Burns by @Red Iron Crown. Thank you both!
