  1. It has been done before
  2. Tere's a huge difference between Eves sea level and eves highest mountains. You have good chances on the mountains.
  3. Not for 400 tonnes. My plan is to hover from the launch pad. Figured that arresting your horizontal velocity is the hardest part, so I'm going to set down sliding sideways and using the breaks to stop. 2nd attempt: plane (spoiler: bad Idea)
  4. My piloting isn't good enough for this challenge!
  5. Had a similar accident with my gilly mission. also, I'm going for a Moho landing too. I don't want to do my Eve return without maneuver nodes.
  6. I know for a fact that at least the Hammer is not able to lift its own weight on Eves surface Level. they do barely if you set the minimum amount of Solid fuel (I actually use them as a separator for the parachutes). Using them higher up will work, of course, but is isn't worth it. a solid stage needs much more mass for the same amount of delta-v, so taking them all the way up as upper stages increases your overall mass significantly. the only reasonable situation to use SRBs is on the very first stage to get off Kerbin.
  7. 3 Engines for Eve Surface? -Vector -Mammoth -Aerospike The next best would be the Mainsail, but it's ISP is significantly lower than that of the above. I don't know about the twin boar, might be worth a try. I only use the Vector and Aerospikes for my designs (at least one Vector in the center to provide gimbal is very useful), as I can build nice and sleek asparagus Vehicles with only 1.25 m parts. Forget about every other Engine, especially SRBs. Edit: Check this out if you like. It's an especially easy to use Eve Ascent Vehicle
  8. Soo ... My playthrough is going to take a bit as I'm starting to do casual gameplay instead of focusing on the challenge. I have a Lab on its way to Minmus and finally managed to get a fuel-delivery to Jeb. Jeb being Jeb decides to do one or two suborbital hops with his filled up Lander. That's exactly what caused his emergency in the first place! I did more than this, I just wanted to show this rescue as a highlight.
  9. Big thanks to @cratercracker for making the artwork above. The challenge sounds very simple: Save Burbarry Kerman, who is stranded in an orbit around the sun. "What kind of Orbit?" you may ask ... Well, it's nothing fancy: An orbit between Kerbin and Eve, nearly circular, at 180 degrees inclination. Just sign this contract and off you go! See here, how he got there: Don't worry, you don't need the Goliath to get into a retrosolar orbit, you can do it the smart way with gravity assists (I highly recommend a boosted Jool-Assist), But ADDING MOAR BOOSTERS will still be required. To be precise, you should add a whole lot of moar boosters. I tried it myself and managed to rendezvous with him (see my attempt below), but I didn't manage to return him Edit: I did and I'm super proud of myself right now. All balanced mods are allowed. Balanced means that engine configs (TWR and ISP) are stockalike as well as the dry mass - wet mass ratios of fuel tanks. If you want to take on the cost-record, you have to do it with stock parts only. Who recovers Burbarry (without turning on "ignore heat" of course) will be showered with everlasting fame and glory and will get an awesome badge! Get the Savefile here: Or: launch a manned (and inoperable) vessel, open the debug menu, go to set orbit and insert this: Now Save and Recover Burbarry! As always, show what you did with pictures, videos, mission report (mission report alone doesn't count). My attempt with a basic tutorial on how to get into a retrosolar orbit the "kind of smart way" will be found in my next post. The scoring system: There are 2 types od awards to win here: Records and non-record prizes. Records can be beaten while the non-record prizes are given to those who come up first with some crazy/innovative/kerbal ideas, so once you have them, you keep them. Badge: Category I "I tried, but something's wrong" - You set up a close approach with Burbarry. Attempting a rendezvous, you discovered the relative velocity is about 20 km/s. @Aetharan, except he knew excactly what he was doing. Category II "Well, it didn't quite work out" - You managed to actually rendezvous with Burbarry, but have no clue on how to get him home. The Gamer Alchemist: He took this to the next level by doing the challenge in RSS. However, he didn't do the second orbit flip and reentered earths atmosphere at over 60 km/s (twice the orbital velocity of earth) and I don't let that count as a recovery. Still, very impressive. "It's starting to get real!" - Award Hall of Fame: Category III "I can't believe, I just did this!" - You managed to recover Burbarry safely on Kerbin @Cpt Kerbalkrunch made the 1st entry without using any nuclear- or ion engines. To make this possible, he used Jool-assists to lower his delta-v requirements. The reentry was close to maximum reentry velocities. He gets the Grumpy Cat prize. @ManEatingApe did it the brute-force way. using nuclear- and Ion stages, he was able to keep mission time, launch mass and cost surprisingly low. "Rearview mirrow" prize. @ManEatingApe made a second, completely different entry to take the cost-record. The mission took literally millennia, good thing Pilots don't get payed per working-hour. "Who's Jesus?" prize, Longest mission Time (2.3 millennia) @Aetharan This time-optimized mission took over 50km/s of delta v packed into a 27.5 Mt monstrosity. Time record (159d, 2h, 31min), Heaviest LV (27.5 kt), "Do it as the crow flies" prize(1) @MarvinKitFox built an ultra light ion spacecraft to get the job done. The mission took over 36 years and didn't involve any complicated gravity assists. @Clancy Did it with a very lightweight and cheap rocket wich still had enough delta v for a brute-force attempt. @jonny went for the lowest delta-v expenature and did quite a lot of gravity assists (around 30). The light and cheap rocket that didn't use any nuclear- or ion witchcraft had to use only a fraction of the delta-v all the other entries took so far. All these advantages came at a prize of a good century of mission time. Lowest delta-v expenditure (5219 m/s from LKO), Black belt in gravity assists @jonny wasn't satisfied with just one record on a single launch, so he decided to break 2 of them (and nearly a 3rd one, the one he set up himself). He did so by using his sick gravity assist skills as above and a combination of a capsule for reentry and a chair on a rocket to deliver Burbarry back to Kerbin. Cost record (15,780), lowest launch mass (39.846 t) @marcushouse completed the mission and made it into a video on his channel. Definitely check that out here! Not only did he only use low-tec parts, he also had a crew-capacity of 3 on his vessel. Lowest Tech Level @marcushouse did it a second time too! Because his second try was a completely new approach and not just am improvement of his first one, he also appears twice on the leaderboard. This time around he chose to do a brute-force-attempt with a lot of nuclear stages and even an ion stage. Have Fun and don't be shy to also share your failed attempts. (1) I'm sure crows would fly like that, If they could fly in space with tens of thousands of m/s of Delta v
  10. That's exactly what I wanted to say (maybe not if I missunderstood the English language here (happens less and less frequently)) what I wanted to say is that in the beginning of every playthrough, I care a lot about debris but I keep making mistakes. At some point, I stop caring. I think that's called being inconsistent.
  11. Not at all, you can go for orbital assembly if you like. Looking forward to your entry.
  12. I'm sure having seen Scott Manley doing such a thing in a live stream. I'm searching for the video but can't find it. Sounds like a great challenge! Go ahead and start one before I do so! What reentry vessel are you using? It's not only atmospheric shock heating that kills you, parts can also be destroyed by heat transmission from the heatshield. Make sure the part directly attached to the heatshield has a high heat tolerance itself. Edit: Also, don't use the inflatable heat shield. It hasn't got ablator on it wich makes it explode at more than 5 km/s.
  13. I only allow myself to terminate debris with a periapsis inside of the atmosphere and debris that is left behind from rescue missions (not my fault). All the other debris is my personal eyesore, I have to live with it or clean it up properly. I usually live with it. After a while, so much debris has built up that I stop caring and then things get really messy. Btw, there's an option in the game settings for how much debris is being tracked before the game auto terminates it. I'm not sure, but I think it's set to 500 by default.
  14. Ambishious, but It means you're missing one upgrade opportunity. Maybe you can work a solution out with @5thHorseman. Meanwhile, I have had a coulpe of failures in my playthrough. As a result, Jeb is stranded on the surface of the mun and can't go on EVA. I either have to upgrade the astronaut complex or develop the Claw to get him home.
  15. Sir, he's not a torus, He's a Klein Bottle. I can't reach into the 4th dimension. Does anyone have a 4-dimensional cloth?

  22. Yes, that's right. What's your question?
