  1. For clarification, any submissions must be modeled with some sort of 3D modeling program. Historically, the minimum requirement for this has been to use Google Sketchup, but in many cases submissions have been fully modeled in SolidWorks.
  2. you're gonna need to increase your nepotism score if you want to post shit that spicy
  3. I was forced to clear some PDFs from my Chrome tabs this evening due to memory constraints, so here's some space tism for y'all: A Study To Evaluate STS Heads-Up Ascent Trajectory Performance Employing a Minimum-Hamiltonian Optimization Strategy EXPLICIT GUIDANCE EQUATIONS FOR MULTISTAGE BOOST TRAJECTORIES The Space Launch System Capabilities for Beyond Earth Missions Space Launch System Solid Rocket Booster Space Launch System Core Stage OPTIMAL THREE DIMENSIONAL LAUNCH VEHICLE TRAJECTORIES WITH ATTITUDE AND ATTITUDE RATE CONSTRAINTS POWERED EXPLICIT GUIDANCE MODIFICATIONS & ENHANCEMENTS FOR SPACE LAUNCH SYSTEM BLOCK-1 AND BLOCK-1B VEHICLES Update on the Ares V to Support Heavy Lift for U.S. Space Exploration Policy Orion Quick Facts NASA Space Launch System (SLS) Development: Challenges and Solutions Final Memorandum on the Review of NASA’s Plan to Build the A-3 Facility for Rocket Propulsion Testing
  4. Testing the Saturn M02 with Bl. 5 Apollo in RSS/RO: This thing flies!
  5. Pretty sure "Kalashoid" means "something based on a Kalashnikov", and they are saying this new gun is not that.
  6. OK so I've officially sucked all the fun out of KSP. SLS core stage static fire test:
  7. OK I think the primary issue is that my core stage is too heavy. I'll need to see if I can configure it.
  8. This was the one I'd read that I thought was pretty ok.
  9. Some things you would leave out. The Rangers operate much more independently than Marines do. So there would be far fewer training-hours in a lot of ways. I'll have to find the article I thought was good.
  10. So one of the problems was that I was using RS-25[noughts], but switching to RS-25D/Es didn't really help a lot. I'm gonna try a higher altitude.
  11. This is really weird, SLS Block 1B is struggling to get to orbit. Lemme see if there's any shit I can tweak.
  12. Also, I'm noticing there's a disparity between the masses of payloads in RSS/RO, and the masses of IRL payloads. A fully loaded Orion with LAS and fairings is 78,010 lbs (~35.4 t) according to this data sheet, but in my KSP it's just 27.5 t. Likewise, my SLS Block 2D will "only" lift 70 unadjusted tonnes to LEO, which if we assume a constant ratio works out to about 90 tonnes. Except this ratio doesn't seem to be constant, because a loaded EUS + Orion + LAS and fairing is 175 t IRL, but in KSP it's just 80.7 t. I'm going to test Block 1B here in a second to see what it does.
  13. Orion and EUS in LEO, launched by an SLS Block 2D:
  14. I read either that article or another one in which he says basically the same thing. One of the rare cases where I will agree with him.
  15. Poo. Lately I've been working in RSS/RO, so I've mostly only been using the smaller bits of your mod, like separatrons and things. I did notice that the Saturn M02 seems a bit underpowered, but that's hardly your fault I think.
  16. We were just talking about this the other day, do you know of anyone who is working on a universal wet workshop mod? I've got an SLS core stage in orbit that I wanna put Kerbals in.
  17. Elasmosaurus engine cluster: Statistics: Some fun facts about the Elasmosaurus: >It has twice as many F-1 engines as were ever flown IRL >It is wider than the Shuttle stack is tall >It is taller than two Saturn Vs stacked one on top of the other >and has more than twenty times as much thrust as both of them combined >In fact it can lift an entire fully loaded Saturn V into Low Earth Orbit.
  18. SLS Block 2 (w/ Dynetics boosters) underway: Booster separation:
  19. I'm not sure the analogy of citizen vs. peasant soldiers and modern volunteer vs. conscript armies really holds up in an absolute sense. Armies historically were often "come as you are", whereas most armies today mold you into whatever they want you to be through training and issuance of equipment. This has little to nothing to do with how those armies are levied, for example draftees in American or British armies during the World Wars could often be very well-trained and were no differently equipped than their volunteer counterparts (indeed, the units weren't even separated along these lines). Drafts are typically associated with drops in soldier quality, sure, but that's because drafts are associated with big fucking wars where you need lots of people. The drops in quality during Vietnam, for example, affected both volunteers and draftees (as, again, the units weren't divided along those lines). The point that higher quality infantry can be disproportionately effective is a very good one, however, and something I've tried to emphasize. Going too far in this respect can run afoul of Kipling's "Cheaper Man" problem, but it's still better to have better infantry, especially since in the case of the USA we can absolutely afford both quality and quantity.
  20. RSS/RO insanity: Herein lies the chronicle of the launch vehicle Elasmosaurus. A program to produce a launcher that could lift 2,400 tonnes to LEO in RSS/RO, the Elasmosaurus strained not only sense and reason, but the very fabric of Kerbal Space Program itself. So powerful was the Elasmosaurus that it would often be eaten by the Kraken simply by loading the rocket onto the pad. Its launch leveled the earth for miles, and its booster separation produced clouds of ash that blanketed the coastline, killing crops and animals. Its sonic boom was powerful enough to shatter granite, and its plume could be seen for thousands of miles over the horizon. It was, inarguably, the highest of follies and the mightiest of boosters. Initially, the first stage possessed a mere 66 F-1B engines, just barely more than all the F-1 engines that ever flew, while the second stage was powered by a paltry 18 RS-25s. Not enough! Not nearly enough. By the end, 24 5-segment Ares solid rocket boosters assisted 126 F-1B engines in lofting an upper stage with 30 RS-25 engines, which was indeed capable of hefting the full 2,400 tonne payload to a 185x185km/28deg orbit. But such an achievement was not without its pitfalls. Booster separation... Did not always go as planned, as the parts limit meant separator motors could not be added. On launch, turbulence from the pad vaporizing to gas and exploding often rocked the booster to the side, though it was inevitably powerful enough to right itself. The rocket was far too large for the normal VAB, and had to be assembled externally, but even then it reached such standing heights as to scrape the sky itself, which could cause spontaneous krakenation upon loading to the pad, if the rocket was not carefully placed. In the end, though, the Elasmosaurus conquered all. It conquered the payload, it conquered the pad, it conquered the sky, and sanity and reason and sense itself. Praise methamphetamines!
