Mars-Bound Hokie Posted April 7, 2020 Share Posted April 7, 2020 @JacobJHC, here's my entry for the Jool-5 challenge. I did it in a Sandbox save because I hated waiting for my other missions to get done. I'm bad at Imgur albums, so here are the pictures in individual sections. To describe my entry: Three-person SSTO Fun fact: comes with emergency abort system ISRU and docking-capable Won't need the docking for this case. Science-capable. Specifically Goo Temperature Crew report Pressure Atmospheric GCMS Gravioli scans Seismic scans Mods used for this challenge: MechJeb Kerbal Alarm Clock Getting to Jool from Kerbin Spoiler Anubis II, ready for takeoff Not official for my career save. I just loaded this into a Sandbox because I don't want to wait. Flying with the Skipper engines and eight rapiers Refueling on Minmus. I only filled the oxidizer tanks with enough to get off Minmus. Other than that, I had WAY over 5 km/s of delta-V on NERVs alone after achieving Minmus orbit. Next stop: Jool Parked in high-Kerbin orbit, awaiting my interplanetary transfer burn. Straight shot to Jool. STOP 1: Laythe Spoiler After getting ~16 Mm periapsis orbit around Jool, I fine-tuned my approach to Laythe so that I could aerobrake and still have an orbital apoapsis of over 50 km. That way, I can have enough time and fuel to land where it's sunny. Flying through Laythe on rapiers alone. If this was a career save, I'd have gotten diminished science returns since I've been to Laythe before. Planting a flag on Laythe before refueling. STOP 2: Bop Spoiler After taking off from Laythe, I barely had enough fuel for Bop. The good news is that I made it. Collecting a surface sample from Bop while planting a flag. (Sandbox version of) collecting science on the surface. STOP 3: Tylo (a real doozy) Spoiler After getting off Bop's surface, I used the NERVs to make my burn to Tylo. I then switched to the Lf+Ox engines after my Lf tank fell below the necessary quantity to maintain a balanced mixture with the Ox. I had to pick an equatorial landing site near the craft's orbital path. This one's a real nail-biter. Perfect landing - by the skin of my teeth. Surface sample and Flag 3. All fueled up and ready for takeoff STOP 4: Pol Spoiler Taking off from Tylo Spoiler The secret is: Use up ALL engines, no matter what type or thrust In fact, the NERVs can get rid of the excess Lf that the Ox wouldn't use up. Get over 45-degree pitch as soon as you're airborne Watch your vertical speed meter. If it stays negative for too long, you're in trouble. GRADUALLY pitch downward while your vertical speed remains positive. Ready to make my circularization burn over Tylo with an apoapsis of 172 km Waiting for my interplanetary transfer to Pol from Tylo Planting flag and collecting a surface sample in Pol's lowlands I took a risky move and straight-up hit "landed somewhere" on the MJ landing autopilot while approaching Pol in a hyperbolic orbit. That explains why I landed where it's dark. I didn't bother to show the science collection on Pol, since this is a sandbox save and you should know by now that science points don't count for jack-s***. If this was a career save, you would definitely see it. STOP 5: Vall Spoiler In orbit of Pol, about to make my burn to Vall I left the ore tanks full, but then converted it to Lf+Ox after takeoff. Due to the nature of the slopes, I had to take off in a slightly-inclined retrograde orbit. I think I can make it on rapiers AND skippers alone. About to circularize my orbit over Vall Looks like I won't need the NERVs after all Landing on Vall with A LOT of delta-V to spare on rapiers and skippers alone (Left to right) Tancan Kerman, Fermal Kerman, and Kenby Kerman standing behind the last flag Taken right before the Anubis II refueled for the flight home Started with the Lf tanks all the way, then the Oxidizer with enough just for the orbital ascent on rapiers and skippers. A bit of sliding and mid-air (rather, airborne spaceborne) spinning later, I got the plane to manage a 79-km apoapsis with whatever Lf+Ox I had. Circularized with the NERVs I just need to execute these next two maneuvers before plotting my node back home to Kerbin The resulting Jool orbit is designed that way so that I won't get caught in any of the moon's sphere of influences and get my wait messed up. So long, Vall - and Kerbin, here we come. Going back home Spoiler It's going to be a long-ass flight back home. Fine-tuning my approach so that I'll have a 210-km periapsis. I still will have delta-V to spare when I'm done circularizing my orbit (on NERVs alone), but I'm kind of cutting it close here. Not very circular, huh. In fact, had I continued, I would have needed to use up ~700 m/s of delta-V. To make matters worse, the chances of me hitting the KSC at my current inclination are slim. Time to change that, by first changing my orbital inclination. I'm about to do what's called a pro-gamer move. You guessed it, it was an aerobrake And look how well that paid off so far I need to go around again to lower my apoapsis some more. Second aerobrake down, and I now have a 1.08 Mm apoapsis Still want to lower that while saving some fuel. However, at the same time, I don't want to enter a suborbital trajectory too early. ANSWER: raise periapsis to 60 km After the FIFTH AEROBRAKE, I decided I had enough delta-V to make my own very low Kerbin orbit and get ready to land at the KSC. Getting ready for my final burn to the KSC. I plan to burn a little bit longer than usual so I don't overshoot it and have to turn around. Of course, I could just hit "abort" and parachute the capsule down while I dump the rest of the plane. However, I'm going for the landing. Nothing says "coming in hot" like a plane on fire during re-entry. Approaching the KSC runway. As soon as I touched down, I re-deployed the airbrakes and applied the wheel brakes. I also deployed the rear chute and stopped quickly. OUR THREE JOOLIAN HEROES BACK HOME What do you think? Quote Link to comment Share on other sites More sharing options...

Since I have already proven I can do the Jool-5, I decided to post my craft file on KerbalX. Yes, I know the model is called the T-6 Cannonball. I called it the Anubis II for this run. The KerbalX page comes with detailed instructions on how to use it, including the capsule ejection sequence. Quote Link to comment Share on other sites More sharing options...
RoninFrog Posted April 25, 2020 Share Posted April 25, 2020 Here is my entry for a single stage 3rd level Jool 5. Here is a screenshot of the craft: 7 kilotons, 8 ISRUs, 17 Saturn-V tanks, 17 kerbals, and 1 stage. There is technically room for 19 kerbals, but stuffing kerbals into airlocks is 'uncool'.

JacobJHC Posted May 5, 2020 Author Share Posted May 5, 2020 Congratulations @RoninFrog on completing the Jool 5 Challenge on level 3! The Sauron is quite the mammoth, and your commentary in the thread was most amusing. This was my favorite image from the mission. I'll add you to the leaderboard now, and thank you for being so patient while my semester ended. Quote Link to comment Share on other sites More sharing options...

Maybe independent RCS maneuvering ability can go as well... I guess maybe trying to make things recoverable is hard. Tylo landers shouldn't need to be 10 tonnes.

It all depends on what engine you use. If you have the Making History DLC I might suggest the cub engine (I think that's what its called) or the spark or some twitches.

GRS Posted May 31, 2020 Share Posted May 31, 2020 (edited) Oh...i forgot some early concept...lets go with it... Small Mothership. Mothesheep (Pun intended). Bullet Tylo Lander. RTG Megawatt with Twin Ion engine, it can act as the center of an attachment. Prototype of the Godspeed Badurra lander, made because why not do it when i can ? Sheep v4 Grand Tour set. Status update : 62nd Landing, the only one that has to be done in the Midnight. The only serious part clipping is the Cage shape, which's main purpose is to look cool...

SiriusRocketry Posted June 17, 2020 Share Posted June 17, 2020 Following my embarrassing previous failure, I have decided that I am sufficiently bored enough to consider giving this another crack. Quote Link to comment Share on other sites More sharing options...
SiriusRocketry Posted June 19, 2020 Share Posted June 19, 2020 As the title implies, this is the mission architecture for Daedalus - my next Jool V attempt. Right now, the mission is still being planned- the current mission layout is for Amalthea to aerobrake, either at Jool or Laythe, into orbit using a heat shield structure. If aerobraking at Jool, corrections will be made in Jool orbit to encounter Laythe and enter orbit., and if aerobraking at Laythe, Amalthea will retroburn into a Laythe parking orbit. Amalthea will remain in Laythe orbit for the duration of the landings in the Jool system. Earhart will be piloted to the surface of Laythe and land before returning to orbit and rendezvousing with Amalthea. Earhart will be drained of fuel and left to orbit Laythe until further infrastructure arrives and deorbits the spacecraft. A nuclear tug will dock with Tennyson and transfer it into orbit around Tylo, where it will land, return to orbit and dock with the tug. The tug will return to Laythe orbit and rendezvous with Amalthea, refuelling both itself and Tennyson before venturing outward to Vall. Tennyson's upper stage will land on Vall, Bop and Pol with possible refuelling trips and land on all three bodies before returning to Amalthea. With the mission objective completed, crew will transfer to the habitation modules for the trip home - the tug will switch to autonomous mode and return any remaining fuel to the mothership before deorbiting itself and Tennyson's upper stage. Amalthea will return to the Kerbin system, where it will enter orbit around one of the Kerbin system moons - most likely Minmus - and wait for a standard spacecraft to retrieve the crew and return to Kerbin. Amalthea will remain in orbit and be refuelled either with fuel launched from Kerbin or mined by a possibly established ISRU economy on Minmus, ready for its next journey. Of course the program is working on a much reduced budget after after the failed original Jool 5 mission, where Valentina Kerman was tragically killed on Vall after a lander malfunction. An estimated 200 million kredits worth of space program budget was lost in the cancellation of the Tylo, Bop and Pol landings due to the only pilot's death, loss of mission infrastructure and immediate retirement of survivors Bilman and Alfry Kerman, who both suffered PTSD and passed the kerbonaut recommended radiation limit over their seven year journey. The Daedalus mission may be a long shot, but it is our last shot. We're functioning on one-tenth the budget and one-sixth the manpower: if this fails, the program will be disbanded. Kerbals will forever look up at the night sky in ignorance and confusion, heedless of the knowledge lost. We owe it to our species to succeed in this endeavour, and write the name of Kerbals into the stars.- END OF PRESS RELEASE, KERBAL SPACE CENTER- Quote Link to comment Share on other sites More sharing options...
Grogs Posted June 20, 2020 Share Posted June 20, 2020 Hey @JacobJHC I'm putting together another Jool-5 run as the finale of my Kerpollo challenge. I'm putting the photos on this thread: Here's a description of my entry: - Making History 1.9.1 - Normal difficulty science mode - 10-kerbal crew; 2 for each moon - Aiming for a Jeb's level since Kerpollo is all about gathering science. - Ship: Joolollo Victory; It will separate into three distinct parts at Jool to tackle Tylo, Laythe, and Val+Pol+Bop. - Kerpollo rules: single launch; all landers must redock with a kerbed orbiter after landing Quote Link to comment Share on other sites More sharing options...

As for fuel, in my experience, asteroids don't usually provide enough ore to be worthwhile. Quote Link to comment Share on other sites More sharing options...
sturmhauke Posted July 22, 2020 Share Posted July 22, 2020 I'm not sure what the thermal tolerance of a space potato is, but it's probably not worth the effort trying to use one as a Laythe heat shield. Usually I enter the Jool system with a Tylo gravity brake and then go from there. Once you've slowed down, Laythe's atmosphere is about as survivable as Kerbin's, although it has somewhat different properties. Quote Link to comment Share on other sites More sharing options...
