It will be fun to watch but I doubt anyone will be able to do it. Scratch the DRE and they might make it (in a few days, that is).

Using monoprop isn't allowed, that'd be too easy. There were even pure RCS rockets.

Use 232Th, problem solved.

I guess this would be considered as cheating but I'll post it here nonetheless just for fun

I know. Still interested in what people will come up with.

My score is 27, which is "Not even close" , I wasn't aiming for it though and had two cockpits and some unnecessary parts.

I present unto you The Least oxidizer to orbit challenge The goal The goal of this challenge it to get at least to the LKO using as little oxidizer as possible while utilizing conventional propulsion. Rules 1) No SRBs, xenon or monopropellant including eva allowed 2) No mods except utility (e.g. MJ) or structural parts 3) Provide screenshot from before launch (not necessary with SSTOs if you provide mission results screen but still preferred) 4) Infinigliders are allowed but will have separate leaderboards 5) The final, stable orbit has to be around Kerbin but you are allowed to leave its SOI momentarily (e.g. use the Mun) Scoring Score is calculated by oxidizer spent including decoupled stages obviously. In case KSP starts to show decimals it is rounded mathematically. Infinigliders, manned and unmanned crafts will all have their own separate leaderboards. Ranks by oxidizer expended 0 : "I bend the nature to my will" 1 : "There can be only one!" 2 : "One giant leap and one small step" 3 : "Threedom!" 4 : "Poker" 5 : "High five" 6 : "Number of the beast" 7 : "Lucky" 8 : "Break shot" 9 : "Pluto" 10-19 : "So near and yet so far" 20-30 : "Not even close" Special achievements Use no engines at all : "The force is with me!" Get single digit rank with craft heavier than 10 tons : "Mass Turbation" Leaderboards Manned 1) Rhomphaia - 0 2) Kasuha - 0 3) tavert - 0.12 4) cyberklad - 2.17, "Mass Turbation" award 5) Richy teh space man - 9 Unanned

I really didn't want to believe it but I flew faster in my SSTO than I did in my dedicated jet (no oxidizer expended as you can see), it was even a two seat plane with many redundant parts:

Lol. Or "You'd look better if you decoupled some boosters".

WOW, you're gonna have babies! Congratz. Seriously though: Squash it (at a distance if you're afraid) or buy a terarium

Power wouldn't be much of a problem even with current level of thechnology. Solar until it's unusable and then thorium reactor. Not only is it everywhere but for one facility? Would last forever. And yes, there can be errors and the error checker can make an error, too but that's okay, right? Those arguments don't matter if the keepers are intelligent. Make multiple AIs take care of it. The only difference between that and people would be that robots are easier to mantain - repairs and energy is all they need.

I realised that afterwards but it should've been obvious. Sometimes I'm really disappointed by my stupidity.

Isn't that the case now? And you can even permakill one of the three if you tweak the settings.

When you start teaching your friends and family orbital mechanics. Most of my friends are programmers or mathematicians though, so they don't find it that strange

Yeah, just found out it's the Twin Paradox:rolleyes:. Anyways, thanks for your help. Edit: "naive application of time dilation" in the article made me chuckle.

Makes sense but let's say we have two ships. One moves away from the other in a straight line at high velocity and then returns. Would they experience time dilatation? There is no difference between them, it doesn't matter which one fires engines, they could just be shot from one point in opposite directions.

Laws of nature aren't invented and to not make this an alternative universe to a one where I pass my exam tommorow, I should go get some sleep (2:50 here)

Just found this: http://www.edu-observatory.org/physics-faq/Relativity/SR/experiments.html#Clock_Hypothesis Seems like it IS velocity and not acceleration.

Depends on your point of view. In quantum mechanics it could travel even faster than light. I prefer to view gravity as a curvature of space because otherwise we have those backhole problems.

Really? Even so, what's the difference between you and earth then? Yeah, I know that, read the opening post. Also, would the time dilatation be reversed if earth had engines and flew away from the ship and back?

The thing is those universes with different outcomes cannot share the same past. In quantum mechanics one state will always have unfold in the same way if reset, so those universes were actually never the same.

If it were only acceleration, then it wouldn't matter how long you orbit earth, the time difference would always be the same. That's not the case though, is it? You age slower in the orbit.

So, this is probably an elemental question for most of you here but please bear with it. I think I quite understand time dilatation as an effect of gravity but not so much with velocity as velocity is always relative. If a ship was moving relative to earth at 1/2 c, that would also mean that earth is moving relative to that ship at the same speed, no? Then how come that the clocks on those two bodies would show different time after their reunion, not taking gravity into account? Would it also work in an isolated system with only earth and that ship since there wouldn't be any difference between them except their mass?

Basically what I wrote. Intelligent machines capable of self repair/uprgrade/replication situated on the Moon.

As Moon is also a satellite, I would certainly situate it on the near side of the Moon, perfect for taking pictures too. As for the hardware, there would have to be intelligent or at least semi-intelligent robots capable of self repair taking care of it. Or magic.
