  1. The Lindor V mission was the finale to completing my JNSQ career save. Huygen is probably the prettiest moon to visit, though was on the same challenge level as Eve. A big thanks to the mod team for making this planet pack.
  2. got it from my external. here you go, my whole VAB folder from the career: https://www.dropbox.com/scl/fo/neinkjj9q4nx70x5cuz91/h?dl=0&rlkey=zqof556ypiixiknrricdeowgt
  3. Hi. I did finish the final tours and the last video for Lindor is getting Edited currently. I've nuked my install so I could install RO/RP-1 but I'll get my craft files from my backup drive and share to kerbalx.
  4. Eeloo Reusing the crew transfer vehicle from the Hamek mission as the distance was very similar, the Eeloo mission would end up being the cheapest one in the career. For this, it only had to refuel LH2 and supplies, and docking a new adapter to dock 2 crafts in a "Y" configuration. The standard command capsule used for sending the crew to orbit would be modified with landing legs to act as a lander for the 2 moons orbiting Eeloo. this was also done to fulfill an exploration contract requiring to return a craft that has orbited Eeloo. Total mission cost: 349k Eeloo Mission Video
  5. Jool V Lessons Learned From the completion of the Jool V mission came a few findings that will help sculpt future JNSQ missions. Although there was ample space for the crew, stress was still a problem that began causing problems towards the end of the mission. There were 3 stress-induced failures that occurred on the return leg of the mission, one of which impacted a VASIMR engine. Cutting down the transit times would become a priority, and would lead the career into Far Future Technologies. The Next mission would be to visit Hamek, on the power of a Afterburning Fission Fragment Rocket Engine. Total mission cost: 1.8 Million Hamek Mission Video
  6. Jool V This was a very involved mission to plan for, and several close calls throughout the trip. For this, I'll just post the videos. Jool Mission Videos
  7. Mission Planning and Design: Gilly and Eve Landers This mission is the first time I have ever landed on Eve, which I didn't even do in the stock system. The first lander design began as a LF/Ox approach using Eve optimized engines, but was scrapped once it was realized that it was 284 tons, and would require orbital fueling and a massive departure/capture stage. The next iteration used the Kerbal Atomics nuclear aerospike, which brought the lander down to 167 tons. A considerable improvement, but with the narrow base and tall stance, it was prone to tipping of not landed on a flat terrain as tested in KRASH. The other problem was the method of entering the atmosphere, which required inflatable heatshields on both ends. The dense atmosphere also create complications with decoupling the lower shield, which even with sepratrons to push away and to the side could still fall back into the craft. This brought me to the final design. The use of asparagus staging meant that the craft could be much shorter. The bottom of the tanks can have heatshields, and with the heat tolerance of the aerospike, it could aerobrake. For stability, control fins were needed at the head of the craft, and were installed on decouplers to ditch once the craft slowed enough. It was also a more manageable 62T, which became 147 tons with the transfer/capture stage and de-orbit stages added. The transfer stage included a small fission reactor to provide sufficient power for cryo cooling the liquid hydrogen. The Gilly portion was simple to design as it only required 70 m/s for a landing. A habitation extension package was designed to include a hydroponic module to test the concept of food production during interplanetary missions. This was docked with the Moho-CTV with the addition of a mapping probe that would map the biomes of Gilly and complete a SCANsat contract. Total mission cost: 2.14 Million Kerbin Departure Crew Roster: Jeb (Pilot) Bill (Engineer) Bob (Scientist) Gilly Segment Year 24, Day 351. Mission time of 157 days, the crew arrive at Gilly. The probe is deployed, and performs an RCS burn to transfer into a polar orbit. After a few days of scanning, the crew land on Gilly. Eve Segment The Gilly lander is left in Gilly orbit as it has served its purpose, and the crew departs to Eve. The Eve lander is a bit spartan, and requires the crew to go on an EVA to board the craft. Landing is nominal as the parachutes were sufficient for a soft landing. Walking on the surface required some finesse, as there seemed to be some glitch where you would begin to sink into the ground, and can Poof the kerbals if you go deep enough. Moving on the surface required takeing jumps every few steps to reset the sinking. Ascent back to orbit was executed without any issues, however I forgot to change the quality of the aerospike to "high" and it only had a single ignition. This meant an engineer had to make a quick sub-orbital EVA to fix/reset the ignitions prior to circularization. From here the crew segment decoupled, and waited a few orbits before making a small RCS burn for a rendezvous intercept with the transfer vehicle. Return to Kerbin Year 26, Day 55. Mission time of 1 year, 226 days, the transfer window to Kerbin opens and the CTV burns for a return trajectory. Year 26, Day 219. Mission time of 2 years, 25 days the crew return safely to Kerbin.

  8. Mission Planning and Design: Moho With an expected Delta-v requirement of 17,000m/s for the round trip, it was determined that NTR would no longer cut it, and the use of pulsed inductive propulsion would be used. For improved performance, the command module would not travel with the transfer vehicle, and be left in high Kerbin orbit. Additionally, an "all-up" approach would be used to simplify the mission, and to provide the crew with a tad more living space for the first half of the trip. Electrical power for the engines provided via a fission reactor, which is placed into hibernation to save reactor fuel once burns are complete. Solar cells to provide power during remaining phases of the mission, with sufficient battery capacity for times in the shadow of Kerbin and Moho. Total mission cost: 1.17 Million Moho Departure Crew Roster: Leemund (Pilot) Hayzer (Engineer) Jedfry (Scientist) Year 22, Day 62. The crew take off on a Pegasus V and perform a rendezvous with the Moho-CTV in a 2Mm orbit just outside the radiation belt. A 2,867m/s burn is performed for the ejection to Moho, expending the 2 drop tanks mid burn. Within 134 days, the crew enters Moho SOI, and capture with 5,4010/s of Delta-v. Moho Mission As radiation is moderate at Moho, the exploration rover is first deployed to perform some scans and science collection. After the crew departs it will remain active and explore an additional biome. Year 22, Day 202. Mission time of 140 days, and the first steps are taken on Moho. The higher gravity and radiation makes it difficult to explore more than one biome, so after EVA reports and surface sample collection, the crew departs the surface. Return to Kerbin After 74 days in Moho SOI, the transfer window to Kerbin opens. A 5,872m/s Ejection Burn is performed. In order to increase efficiency and prevent a possible lack of delta-v to capture at Kerbin, 2 thrusters are deactivated to allow a higher electrical input to be diverted to the 2 active thrusters for a higher ISP, expending less argon fuel. Year 22, Day 357. Mission time of 295 days marks the return to Kerbin's SOI. Roughly 3,000m/s of delta-v is used for the capture and rendezvous with the command module still in orbit. 3 days later, the crew safely returns to the Surface. Moho Mission Video
