    Tricky Contract

    It's been a while and I'm having trouble getting my head around getting a satellite in a retrograde (Duna) orbit close to the orbit of Ike. Any ideas?

    Tricky Contract

    Yeah, I thought that a complete orbit had to overlay the required track but apparently not. Contract complete. Thanks for the reply.

    Explore Duna contract not completing

    Had one not too long ago - unfortunately I can't remember when this one was ticked.

    Is MechJeb hate still a thing?

    I have multiple KSP installs - some with MJ, some without. I really enjoy playing all of them.

    Limited crew control why?

    Try Tutorial:Setting up a CommNet system Use a Resonant Orbit Calculator to space the relays in orbit.
  6. I really like the idea behind the scheduling options for the bi-impulsive transfers. Thank you.
  7. Try Kerbal Joint Reinforcement.
  8. Strangely enough, Mechjeb seems to manage staging tanks ok, but put engines under those tanks and it refuses to stage them unless fuel ducts are used. Though maybe I'm missing something.
  9. If you hold the shift key down when using the "w" key, your kerbals will run instead of walk. Like the look of your rover.
  10. Coming from you, that's a heck of a compliment.
  11. Looked like it might be a reasonable time @Klapaucius, so I tried again - here is 4:58. (This is my first ever video upload - apologies if it doesn't work out too well)

    Hydrofoil Building Help (2nd Post Attempt)

    Wow, that's fast. What sort of range I wonder? And yeah, my boats suck but I never try to build the Mona Lisa. Twenty hours around Kerbin includes design/test/mission time. I think it would be easy to spend that long just learning to build something that went 400m/s.
  13. Yeah - torque from the reaction wheel and the cockpit flips it really, really easily. Yet once it gets going, SAS keeps it pretty stable at 60 - 70m/s as long the authority limiters of the canards are set correctly. Range is about 300km. Notice this one is still carrying an ISRU.
  14. Unfortunately, when Jeb climbs out to plant the flag, he starts his own timer from zero. Anyway, just to get the ball rolling, here's a time of 8:19 - timed after planting the flag and jumping back into the rover. Shouldn't be hard to take a couple of minutes off that time.

    Hydrofoil Building Help (2nd Post Attempt)

    I'm sure there are a shedload of great boat designs out there but you're right - the range of the craft is nearly as important to me as speed. I think it took me about twenty hours all up to go around Kerbin and I stopped to mine ore seven times although my tanks were usually far from empty. Without an ISRU, if you had to fly a seaplane in each time, well, that might add to that total time. And for an equatorial circumnavigation of Laythe - using an ISRU to refuel - you need a range of about 1200 - 1300km. The first time around Laythe, I ran out of fuel in the middle of the Degrasse Sea. That left a bad taste so I went back again with the boat below - with two Panthers, it had a range of well over 2000km at speed so after splashing down with full tanks, it needed to be refueled just once to complete the circumnavigation. But it was a pita to drive.

    Hydrofoil Building Help (2nd Post Attempt)

    Once you've been around Kerbin in a boat that's also a rover, you can look forward to doing it again in a rover that's also a boat and a polar route is for sure the best for this trip. Helps if the rover can climb up onto the ice shelf. (This puppy went through the water upside down)

    Hydrofoil Building Help (2nd Post Attempt)

    No. You must make a land crossing at some point. As @bewing mentioned, wheels are essential and while there are wheels on this craft, there are none that are steerable. @Klapaucius's design in the video looks pretty cool except that it's a sod of a long way around Kerbin so some speed comes in handy - it would have been good to see what happens when it was moving three times as fast. (And to see what happens when the CoM moves as fuel is depleted.) Although it's easy to make very fast boats, bad things tend to start happening when you push it over 100m/s so a maximum cruising speed of 95m/s has always seemed prudent to me. I had a play with the boat - you can stabilize it by moving the foils toward the ends of the craft and adjusting the authority limiters. So I get it skimming across the water and full throttle it's doing 75m/s. Pretty sad with those two giant engines. I prefer Panthers, either one, two or four of them. You might also have a look at what parts you put in the water and do what you can to minimize the drag. I'd also suggest coming up with a design that sits just above the water - it's likely that you will have to make trim adjustments as you use fuel and craft sitting high above the water are easier, imho, to nosedive or flip when you start playing with the controls at speed. At some point you'll need to refuel. Probably multiple times. You can either fly a tanker in to do it or carry mining/conversion equipment. Personally, I prefer the latter. You might also take note of the range of the boat in case you're tempted to go to Laythe. The boat I used to go around Kerbin used just two canards to lift most of itself just clear of the water. The four Panthers used wet mode on full tanks before switching to dry mode in pairs and were progressively throttled back to stay under 100m/s. Best of all was finding a fuel flow priority sequence that made any pitch/trim adjustment unnecessary. This was the first boat I ever made and embarrassingly enough, it's still probably the best (and it's not that good either). Traveling around Kerbin - three quarter throttle in dry mode - 100m/s.

    The "Douglas Adams" Challenge

    @dnbattley - launch mass of the Eventually is 290t and imho should be listed as KSP version 1.4.5 - not 1.4.5MH.
  19. For your reference, the wiki lists the MH parts here: https://wiki.kerbalspaceprogram.com/wiki/Category:Making_History_parts
  20. If you have a scientist along for the ride you can remove the science from the Science Jr. Maybe put the service bay at the bottom of the central stack and stage it before liftoff.
  21. You could try putting the Science Jr in a 2.5m Service Bay.
  22. Try using two inflatable heat shields - one on the top and one on the bottom. Also you could try reducing your orbit to something like 90-100km before deorbiting - ie so that your speed is down to around 3200m/s before starting your deorbit burn at the top of the atmosphere. If you have enough fuel and can decelerate to around 800m/s by the time you hit about 60km you can even ditch the heat shields altogether. But if you're going for the big aerobrake, they tend to flip and you'll probably need the two heat shields. You can even get creative and try turning one of the heat shields upside down. Normally when you add an inflatable heat shield to a craft, it won't inflate - either in the VAB or in flight - if something is attached to the pointy end. But you can get around this by first using the rotation tool then the offset tool. (Be aware that if you then detach/reattach the heat shield it will no longer inflate and you will need to start over). You will also need to use the offset tool to attach another part to the other side of the heat shield. However, I'm not sure if this will make any difference to any propensity for flipping. With two heat shields, possibly the thing that will have the most effect on stability is the distance between the heat shields.

    The "Douglas Adams" Challenge

    Eventually made it to Eve and back. Pretty glad this one is finished and 'Eventually" seemed like a good name for the ship. The Eventually is like that whimpering three legged dog you felt sorry for when you saw it. You wanted to give it a pat to cheer it up but didn't really want a stray mutt following you home so you contented yourself with a look of concern as you passed it by. But that was enough. It attached itself to you and you looked after that dog until the day it died despite it's obscene vet bills, the appetite of a small horse and an almost constant, eye-watering and silent flatulence. Take it home to meet the family? You bet. Probably the hardest thing about this challenge was coming up with something a bit different to those designs already submitted. Difficult when there are so very few engines capable of lifting off from Eve. I did my best though. In contrast to previous solutions, I did not kill or leave behind any Kerbals. I did not use any pilots - auto or otherwise. Bill went there and back by himself. This was a single Kerbal mission. No mods were used in the mission - this includes MH parts. And neither KER nor MJ were used to design or test the craft. Courtesy of the Twin Boars, the Eventually may be the heaviest craft to lift off from the surface of Eve so far. Handles like a dream too. It is a two stage ascent vehicle with three Twin Boars in the first stage and a single aerospike in the second. Staging occurs around 20km up after being progressively throttled back once velocity reaches about 500m/s . Because of the weight, like @Laie, I was forced to refuel on Minmus before taking a dive to Eve. I had quite a few false starts to the mission - something always went wrong, forcing me to start again. On this final attempt I couldn't jettison my top heat shield without destroying my craft. Finally I tried leaving it deflated and reentered without incident. Possibly I could have left it off but I'm not sure what I would replaced it with. Testing designs gave me a lot of practice launching from Eve so after refueling I made orbit on the first try - almost matching the plane of the return vehicle. It would have been easy to provide a bigger tank for the return. I just never got to practice that part. As it was, Bill made capture at Kerbin with 3.55/4.34 LOX remaining. And after about fifty shallow dips through the atmosphere, Bill finally splashed down.
