KERBAL SPACE PROGRAM CONTROLS CHEAT SHEET MOD
The only parts mod I'm using is the Kethane mod. And the ascent stage has a stupidly unnecessary amount of delta v, 1000m/s is at least five times more than you need to get back to Kerbin from the surface of Minmus, but the only reason it has that much is because you can't actually give it less without using the orange donut tanks. That lander I posted above has MORE than enough thrust for Minmus, even with all of the fuel tanks full. You don't need much more than a single LV909 for Minmus operations, and two of them for the Mun. You're probably bringing too much thrust. I've been trying to avoid MechJeb until I can manage to eyeball an efficient two-part lander, but Bill, Bob, and Romin are feeling a little impatient up there in Munar orbit. I tend to run a single piece third stage with a pair of radial drop tanks that get me through the Mun insertion and half of the descent, then an inline tank gets me down and back home. About 80% of my attempts end up with three stranded Kerbals, zero fuel, and most of a re-insertion burn left to go. I don't get you people and your Apollo-style landers - I fuck them up just about every time. There needs to be at least 3 for much easier thrust balancing, but I think I'll stick with four. I should add that both designs are using four engines. Of course, the design may require further modification because of how much longer the nuclear engines are compared to the 909s. Should be plenty of thrust for the Munar environment. That should be a much, much more flexible platform, especially considering the T/W is only 13% less with a 72% increase in fuel efficiency.ĮDIT: Based on the 1/6 Munar gravity approximation: With a slightly modified design (Very similar, but a little bit more monopropellant), and the nuclear engines, it'll weigh 25.84 tons, have a T/W ratio of 0.948 and can burn at 100% for 394 seconds. At max fuel, it weighs 18.53 tons (1G), has a T/W ratio of 1.089 and can burn at 100% for 229 seconds. So, my current heavy skycrane uses the Rockomax LV-909 engine, the second most efficient engine. Next up, the (apparently slightly easier) trip to Minmus and back.
He didn't even have to get out and push like Jebediah did, though he did require two extra spacecraft to return home whereas Jebediah brought his original craft back with him (the showoff). Rodcal Kermin, and more importantly his 400 SCIENCE, returned safely.
There was some question if there would be enough fuel to get back to Kerbin, but a careful plotting of the course resulted in a safe return (eventually). Rodcal ended up doing a 2.2 km EVA to get to his new craft. Somebody isn't getting any snacks during lunch tomorrow! Thankfully the craft was designed to land on the Mun, so it had sufficient delta-v to orient its orbit correctly after arriving. The science team apparently dropped a - somewhere, as the second rescue mission ended up orbiting in almost exactly the opposite direction as Rodcal. Questions were raised about Rodcal's current craft being in a polar orbit, but confidence was high that a polar insertion would make a rendezvous simple. Undaunted, Mission Control adroitly setup another unmanned Munar lander to meet up with the other one in orbit, hopefully close enough for Rodcal to be able to EVA across with all of his valuable SCIENCE. The Stayputnik proved its worth by landing roughly 800 meters away from the previous lander, though some issues with the descent left only enough fuel to get to Munar orbit, and not enough to return to Kerbin. Once certain design deficiencies were corrected (the lack of solar panels being the most prominent), the mission was a go. This proved impractical with the current state of Kerbal technology, so the previous Munar lander design was modified to have a Stayputnik atop the crew capsule (which is empty on the way up) and a larger fuel tank on the lander itself. The first idea was to send a 3 man capsule with 2 crew to go and get him back. Well after stranding Rodcal Kerman on the Mun with insufficient fuel to even reach Munar orbit, a rescue mission was needed.
