What you are thinking about already exists. Copenhagen Suborbitals is crowdfunded and everything they do is open source.

Blast something into space on a single stage solid-fuelled rocket? No problem whatsoever. Some sounding rockets are basically that. Send something into orbit on a single, non-stages solidfuelled rocket? Not possible with current technology. If it was, it was being done already because solid fuelled rockets are cheaper than liquid fuelled ones because of the lack of complex plumbing.

From how I understand the question, Gregrox is more or less suggesting another existing engine, but not a turboprop. It's simply the high-bypass turbofan. If you don't know what that means, here's the crash course (tee hee) in turbofan engines: The central piece of the engine, the long tube with small diameter, is essentially a turbojet. This is the "classic" jet engine where a series of blades compress air, which is then mixed with fuel and ignited. Then at the back, said air passes over some turbine blades that drive the compressor blades in the front. Now, in a turbojet, the first compressor blade is much larger than the other compressor blades. This is because this blade acts not only as a compressor, but also as a ducted fan, which is essentially a propeller with a casing. You will notice in the cutaway above that there is a large outer tube in the front. This is the "bypass", air that is simply pushed through the tube by the compressor, driven by the central turbojet, creating thrust. In a lot of cases, even most of the thrust of the engine! This is much more effecient use of the jet engine than a traditional turbojet, and it is much less noisy too! I hope this was what you meant.

This thread has no god damn place on the KSP forum. Seriously, this is ridiculous. I hate people who cry about whaling with a passion. Here's why: People watch that ridiculous Whale Wars show and think it is unbiased and that it is a good representation of what it's all about. They think it's cool when the stupid spoiled kids on that ship attack other ships, but suddenly think it's oh-so-unfair when the Japanese do anything back, like holding people that board the Japanese ships captive. It's piracy and they should be punished to the fullest extent of the law. Same story with Greenpeace and the Russian oil rigs, but another story another time. Also people seem to be awfully, awfully concerned about whaling while completely ignoring much more important issues. Help the god damn people in your own country to decent living standards before crying about other countries hunting a type of animal you think is cute. Same with people who think it's oh-so-unfair that the Chinese have dog farms, but happily eat their cheap chicken from chicken farms. Focus your resources on something that matters. Think globally, yes, but start by acting locally. Care about animals? Adopt one from a shelter near you. Care about the environment? Don't pour chemicals all over your lawn to make it look nicer. Seriously though: THIS THREAD HAS NO PLACE ON THE KSP FORUMS AND SHOULD BE LOCKED AND/OR DELETED

According to the same article on Spaceflightnow, SpaceX would in theory be ready for launch today, but due to Thanksgiving air traffic, no launches are permitted from the cape.

Because the "Orion Drive" in the movie has nothing to do with our beloved nuke-pooping spacecraft, unfortunately.

You wouldn't need a G-suit at all unless you're really overweight. 4G isn't a lot. You would need some sort of oxygen supply since the Cargo Dragon has a very limited amount of oxygen - for returning some experiments it is needed to have an environment with an oxygen atmosphere in order to keep things as close to the ISS as possible, but since there is no intention to use this version for actual human beings, there isn't a lot of it. Regarding the splashdown I don't think it would be too bad, really. It is water we're talking about, and yes, it will be uncomfortable and I would recommend lying down on the bottom (but who would be standing anyway?). If for some reason the burn had a malfunction and you were headed for a landing on dry land? Well... The cosmonaut who landed in a Soyuz with no braking rockets broke all of his teeth during landing even though he was in a suspended seat.

For it reenter? A VERY long time. In fact I don't believe it would ever happen unless some gentle asteroid slowly and gently pushed the satellite onto a sub-80 km perigee. Solar winds and the Moons gravity does have an effect on the orbits of those satellites, yes, as do the tidal motion of the Earths oceans, but it is not something that will actually force the satellite out of orbit. But for a satellite in geosynchronous to leave geosynchronous? That happens a lot. In fact i does require more or less constant stationkeeping maneuvers to maintain a geosynchonous orbit. Therefore, most geosynch satellites do not have a perfectly synchronous orbit, as that would use up their maneuvering reserves a lot. I am not sure about the tolerances, but once a satellite gets too far away from the original position, it will be maneuvered back, and once the fuel reserves are nearly depleted, it will be boosted out to a "graveyard orbit" slightly beyond geostationary. I'm not sure if that answered you question, but hell it's the best I can do, haha.

I recognize those 3D models all too well - the sequences showing the exterior of the Soyuz during burns, re-entry and so forth, in fact everything is recorded in Orbiter2010 with the ISS/Soyuz pack! But a great video overall.

I'm just gonna leave this here http://www.braeunig.us/space/orbmech.htm Includes examples of calculations if you follow the links!

Succesful launch has been acheived - now let's see if it can rendezvous too!

A real problem in KSP is that using N-body mathematics on the planets and bodies as they are now means that the entire Kerbol system is very unstable. I recall a lot of guys making the system in Universe Sandbox, which does have accurate physics, and watching it all fall apart. Especially the Joolian system is impossible. In other words, it takes a lot more than a rewrite of the physics engine to allow KSP to be similar to how KSP is now, while gaining the ability to have lagrane points and do gravity captures and so forth.

That is, unfortunately, just how KSP is. It's a very demanding game, as is simulators in general - it's not about your graphics card or your RAM, but about how fast your processor is, and I'm not sure an i3 cuts it. I'm playing on an i5 3.4GHz and still I do not get smooth gameplay with larger crafts and rockets - it's simply just a thing you'll have to get used to.

Even satellites in geosynchronous orbits experience atmospheric drag as well as gravitational pulls of other bodies than Earth causing orbits to change over time. A stable orbit as in KSP does simply not exist in the real world. Regarding debris, however, you'll have to take several things into factor: How big is it? How aerodynamic is it really? How eccentric is the orbit? Some of the spent rocket stages re-enter after just a few days - when COTS2 Dragon was "dead", it would re-enter automatically with no thrusters fired after 4 days, as would the spent 2nd stage of the Falcon 9 - and the 2nd stage of course did re-enter.
