Extremely impressive! No ISRU, fully recovered, no planetary gravity assists and highly enjoyable to watch. I've been working on a fully recoverable, non-ISRU Jool-5 lately, you have given me much to think about. Quote Link to comment Share on other sites More sharing options...
JacobJHC Posted July 11, 2021 Author Share Posted July 11, 2021 On 7/6/2021 at 5:54 PM, Lt_Duckweed said: I just finished my first ever Jool 5. With the added twist that: 1. The craft travels from Kerbin to Tylo orbit as a single stage, then to laythe and back home as a single stage. 2. All parts are recovered on the runway at the end of the mission. 3. No isru, aero exploits, or abusive part clipping are used. 4. The transfer to and from Jool is direct, no assists. 5. And finally, it only uses 2 engines, one Rapier, and one Nerv. This would qualify for Level 1, and I dont think it qualifies for any special accolades, as it is too heavy for low mass, too costly for low cost, and too partly for low part count. Congratulations @Lt_Duckweed on completing the Jool 5 challenge on the 1st level! The design of this craft is very unique, I felt like I was watching an alien spacecraft. Additionally, your mission is only one of a handful of Jool 5 submissions I have seen which utilized nuclear engines for Tylo landings. I must say I think this is one of the first Jool 5 missions I've seen in which Laythe was the final moon visited. The video is well edited as well, and I will be adding you to the leaderboard now.

Dr. Kerbal Posted July 14, 2021 Share Posted July 14, 2021 I said I would do this before. But I am going to try again. Because I shortly ran out of fuel when I just orbited around Pol. Quote Link to comment Share on other sites More sharing options...

camacju Posted July 15, 2021 Share Posted July 15, 2021 I'm curious as to why you'd want to do it in 0.19 Quote Link to comment Share on other sites More sharing options...
KSP_linux0191 Posted July 15, 2021 Share Posted July 15, 2021 (edited) Because the planet terrain maps were different in pre-0.21 versions of the game. Also, the unstable physics of the old game would be its own challenge. Edited July 15, 2021 by KSP_linux0191 Quote Link to comment Share on other sites More sharing options...

Anyone can count that many on their fingers! Another thing worth mentioning is that the external command seat was not available until version 0.20. One thing that I have found out from transitioning old parts to the new simulator is that the old parts are visibly smaller than the new parts when stacked on top of each other. (This can be fixed by tweaking the "rescaleFactor" variable.) Edited July 25, 2021 by KSP_linux0191 Quote Link to comment Share on other sites More sharing options...

Don't we all. High TWR reduces delta-v usually, but adding more fuel then lowers the TWR, and so on and so forth... Quote Link to comment Share on other sites More sharing options...
camacju Posted August 2, 2021 Share Posted August 2, 2021 I forgot that I had been trying to do another low cost Jool 5 - this is my newest attempt: I use a much smaller Terrier stage and a larger Spark powered fuel tanker, as well as stripping down the landers significantly. I have three different landers now. I haven't flown the full mission yet but I should be able to do everything with a good amount of fuel left over.

No - you have to pack the lander in cargo containers and then unpack it in orbit. Won't give any advantage that way. I basically use EVA construction because 0.1 EVA propellant is a lot lighter and cheaper than a decoupler, so detaching used fuel tanks is easy Quote Link to comment Share on other sites More sharing options...

camacju Posted August 24, 2021 Share Posted August 24, 2021 Here's another potential Jool 5. Not low cost, low mass, or low parts - I'm going for low engines. I'm going to try to land on all five of Jool's moons using only one Rapier engine for the entire flight. Here's a preliminary image of what the craft might look like - I need to test some things still (The Laythe and Tylo landings specifically) but this will likely be pretty close to the final design.
