Do you think the aliens play Kerbal Space Program?

This might be a dumb question, but am I allowed to use this mod in my youtube videos?

Thank you for the input. Firstly, are you saying my demographics things is lying to me? It probably is. Second, I have been planning to add a logo/channel wallpaper thing/thumbnails. I just don't have the time right now. Third, my videos do have a short phrase before the ep number. You are probably only referring to my first 2 videos. Fourth, my identity will certainly be there, it just hasn't had its time to shine yet. Fifth, I am patient, especially since my only youtube rival is progressing very slowly as well. Sixth, My supposed unoriginally will change once other games make their way onto my channel. You have not seen anything yet. Seventh, and most importantly, I need suggestions for what games to play and what mods to use (if any) on my KSP series.

The only part I made up was 'over the last few weeks...'. In reality I should have said 'over the last 2 years...'.

-37 I have no idea why I am playing this.

Okay, I have tried viewing my videos in spectator mode but I still can't see the comments. Help please. I'm getting worried.

The two things go through each other. That way the object doesn't move and the force doesn't stop.

Please, stay on topic. Thank you.

Okay, new problem: my demographics thing says there have been a few comments on my first video, yet when I look at the comment section for that video it is blank, as if nobody has commented. Why cant I see my comments?

Granted, all rainbows become plain black. I wish Australia could into space.

Two more: If we all take a bucket of seawater and pour it down the drain will that stop sea level rise? Can eggs lay eggs? Are eggs fruit or vegetables? (looks up 'eggplant' on Wikipedia) okay its a vegetable

Over the last few weeks... Is it possible to live without computers? Is downloading illegal files illegal? If people are against poverty then why are they helping poor people? (insert the name of almost any poor country here) is wealthier than America1 Which US states are in the EU? Why do people hate (ISIL/Al-Qaeda/North Korea) so much? How can submarines see underwater? Is America communist? Why don't native Americans go back to China? Why don't we just blow up every country we don't like? Me and my friends are going to start our own country in the arctic circle but the UN isn't responding to our email what do we do now? Did the LHC cause the earthquakes in Nepal? Is the sun the hottest thing in Australia? The earth is 2015 years old! Why do people say the world is round if it is flat on all maps? Why won't they make round maps? If I dug 2 meters into the ground, will I find lava? If the earth started going around the sun backwards, would time go backwards or would the earth's gravity just reverse? How do I build a time machine out of cats? Why can't we land on the sun already? We can go at winter if it is too hot, and we can easily use the geothermal energy! If Mexicans are called 'aliens', does that mean they are from space? Is mexico in space? Why does the sun go around earth instead of Jupiter? isn't Jupiter bigger? Does the sun ever get sick? What is water's purpose on earth, why is it moving, where is it all going, why does it need to move, what is its mission? Why do Africans and Indonesians say they have no water when they are surrounded by water? Is Canada a US state, or a collection of US states? Why are there so many middle eastern people in south west asia? Why are there so many Europeans in the EU? What has happened...

IIRC the Apollo, space shuttle and ISS programs were in the $100-200 billion range Depends how fast you want to get there. For a 2 year voyage the Dv is about 50km/s. (Source: Human mission to the outer solar system: designs and implementations) Life on titan, indeed, would be a greater discovery than on mars or Europa. However Europa is closer and easier to get to. To get to titan you need more Dv, Heat shields, Parachutes, and the knowledge you can't have a cheap-ish sample return because of the thick atmosphere. Europa has a very high potential, and even if its life came from earth millions of years ago, it still is alien life as it has spent millions of years adapting to its environment and becoming a new species. Wait, the American government actually wants this? Not sure if I should be grateful or suspicious... This is one of my favorite space films ever. Just sayin'

Okay, but how will a sail purely pushed by the sun speed up enough? once it gains a few tens of kilometers per second in outwards velocity, it will move away from the sun so fast it cannot be pushed much further. If the sail swings really close to the sun, that might help a little, but its close-range flyby would be very short and would again not last long enough to accelerate to the speeds required. So what's your solution? How do you think solar sails can achieve interstellar speeds?

I like this flag. I also like these ones: http://imgur.com/a/TlEMb http://i.imgur.com/7ze3a.png

Okay, that brings our deadline to 2100. While this may seem doable, remember that the second half of the 21st century will be full of climate disasters, economic recessions, wars, resource depletion and other events that will be a significant problem for scientific research. For more information, watch this ( ) and read this (http://www.amazon.com/The-Collapse-Western-Civilization-Future/dp/023116954X) Indeed, the 4 designs I linked are all very massive and would require hundreds of launches - and billions of dollars - to construct. However fusion propulsion has benefits over solar sails. It can continue to accelerate in deep space far away from a star, and because of this it can go faster than a solar sail. It also can carry a larger payload. A potential 'best of both worlds' approach could be a laser sail. It is like a solar sail except it is powered by a gigantic laser beam. If you look here (https://en.wikipedia.org/wiki/Interstellar_travel) and look at the beamed propulsion section, you can see that laser sail starships can go fast and also carry a large payload. I think our best options are fusion and laser sails.

Europa? Lander? Congress likes? HYPE

I agree that antimatter in any commercial non-purely-scientific use is centuries away. The stuff takes a small country's worth of energy to create a visible amount, and said amount can't currently be contained for more than a few minutes. Also remember that antimatter is extremely dangerous. Just 1 gram of it combining with one gram of normal matter creates a 43 kiloton explosion. For comparison, the nuclear bombs dropped on Hiroshima and Nagasaki only had yields of 15 and 20 kilotons. And this is just from one gram of antimatter, an interstellar spaceship will need several tons of it, enough to wipe off a large continent. Your calculations are slightly off. At 0.1c the trip to the centauris will only take 43 years. But that still means that to get there in this century we will need to launch it in 2057. Good luck getting any kind of 0.1c propulsion system by then. Habitable worlds to would certainly be a large motivator for interstellar travel, like in Civilisation: Beyond Earth. The only problem with the giant laser-sail network you propose is the energy requirements. If you look here (https://en.wikipedia.org/wiki/Interstellar_travel) and look at the beamed propulsion section, a manned expedition to epsilon eridani requires 75 million gigawatts of power. Good luck finding a way to power the laser, or even design one that could cope with such energy. Agreed. Once we have colonized the moon, Mars, Venus, Ceres and the moons of Jupiter and Saturn, and have built huge solar collectors on mercury, and have a few space elevators on earth, the moon and mars, then we can begin interstellar expansion. But only then. This is actually pessimistic if you ask me. With modern technology, Nuclear-electric ion or magnetoplasma drives can probably bring the limit up around 600km/s, or 0.002c. Even with this, though, the centauris are still 2150 years away. Good luck keeping any sort of spaceship operating from now all the way to the year ~4200. This, fusion propulsion, will probably be our answer. Icarus interstellar has already designed 4 fusion probes for alpha centauri, and they all seem doable for the 23rd-century space community. http://www.icarusinterstellar.org/a-ship-called-resolution-project-icarus-workshop-update-14/ http://www.icarusinterstellar.org/meet-firefly-project-icarus-workshop-update-24/ http://www.icarusinterstellar.org/project-icarus-workshop-update-34-the-ghost-ship/ http://www.icarusinterstellar.org/ultra-dense-deuterium-fueled-starship-project-icarus-workshop-update-44/ This is even more environmentally scary than an orion drive. It is basically a continuously detonating orion drive with several times as much radioactive death coming out. Good luck getting permission to use one within a million kilometers of an inhabited area. Firstly, are you referring to the Cold War II that we are witnessing right now? Even if there is a Cold War III, it will never see a space race to another star. The timescales and resources involved are simply unsuited to a political rivalry. By the time the probes get there, the competing nations that launched them will have completely changed to the point where the rivalry that launched the probes will be a distant memory. That will never happen. Never. It is impossible for a species like us to all merge as one nation. If other planetary colonies become their own nations, that might make it slightly more likely. The money is there, it is just being spent on killing people in the middle east and elsewhere, and technology that will make killing those people faster and more efficient. For the most forward-thinking countries, like China and India, the maximum 'government visibility' is about 5-10 years. For America it is more like 1 year, and for Australia it is about 2 weeks. Space colonies with billions of people? Habitats being self-sustaining for hundreds of years? Interstellar colonisation is easier than that. The materials do build an interstellar generation ship do exist on earth. If we can't find enough resources on our national soil we can clear out and mine Greenland or Antarctica. The technologies mostly exist, although there are still unresolved problems. However, generation ships are a concept doomed from the start. You can not have a society in a pressurized, confined area that will remain peaceful for more than a century or so. It is statistically certain that at some point, somebody onboard will sabotage the mission, and it only takes a tiny event to kick off a civil unrest that will inevitably escalate. And it only takes one carefully-placed bomb to blow a hole in the ship and kill everyone onboard. Any manned mission taking more than 100 years should not be attempted at all. Even better, read the book The collapse of Western civilization: a view from the future. It provides a very detailed look at how climate change alone can and will kill billions of people very rapidly in the second half of the 21st century. It also shows why there will be no real motive to prevent the collapse until it is far too late. Leaving earth is not a matter of 'In the unlikely event bad things happen we will survive', it is a matter of 'Bad things are going to happen and we need to survive'. We still need to master the materials technology to make such a sail ship. Once we have, we will need to just hope we aren't struck by a single micrometeoroid, as it would go through the sail like a 20 kilogram bowling ball goes through a glass window.

This is certainly the best 'flags mod' I have ever seen! Great job! You even added Australia

I really really like the idea of this. I hope it becomes a real mod.

, Here's a few things I have to say. First, this post I made in a similar thread: http://forum.kerbalspaceprogram.com/threads/116849-The-Dark-%28seriously-very-dark%29-future-of-human-space-flight/page9 Second, this forum blog I made a while back: http://forum.kerbalspaceprogram.com/entries/3462-The-Future-of-Manned-Interplanetary-Missions Agreed. While there will never be a time of total peace and equality on earth, problems such as terrorism, racial equality, gender equality, poverty, hunger, Cold War II, healthcare, homelessness, WMDs etc etc should be reduced by a significant amount before world governments start colonizing other worlds. Private companies, such as SpaceX, do not have as many such setbacks and should go for it. And it is! Humans could go extinct within the next 50 years from a wide range of natural or man-made catastrophii, but, despite knowing that, we still have hope. Whoa, whoa, slow down there! Bill Gates is doing a lot of good things for the world with his money! He's, like, wiping out diseases and stuff! Or 'not at all' By that scale, I am very slightly below 'Realism'. I'm thinking 15-25 years for SpaceX (2030 to 2040) Nope. When it comes to any world-changing venture, money is always more vital than anything else. If we are going to try to make space payload launching affordable, or try to send humans anywhere beyond mars, chemical propulsion simply will not do. It is only a matter of time before SpaceX, China and India see that. There is always the possibility a sudden nuclear war or climate catastrophe will make conditions on earth so bad that we will prefer to colonise space more than stay on a deteriorating earth. Sorta like the background story of Civilisation: Beyond Earth. the video where they explain the background story can be found here: If we expand our range slightly, that number goes up dramatically with Mercury, Ceres, Ganymede, Europa and the moons of Saturn.

After accepting an offer given for me to join my WWII themed school trip to Germany next year, today at the information night I realized I made the Reich decision. I did Na zi how much fun they were planning to make it. I'm Goering to love it!

As for the LNG/methalox thing - oops. For your next mission design, is say you go for a HAVOC-style venus mission. Bonus points if there is a manned surface mission and surface EVA, like in the film 'space odyssey: voyage to the planets'. I might be able to help with that part.

Will we launch an interstellar probe within this century - maybe Will we launch an interstellar probe this century that will take less than 1000 years to reach its destination - no Will we launch an interstellar probe next century that will take less than 1000 years to reach its destination - probably

I... oh my god... this is beautiful... Just a few questions/suggestions: - liquid xenon has a density of 3.1mT/m3, so have the LXe tanks been sized correctly? - the diagrams seem too cluttered up with all the labels and descriptions. is there a way to make it neater? - the landing engines don't use methane-oxygen (methalox) combustion, so ISRU will be more difficult. - are you sure the ion engines produce enough thrust for the spacecraft they are on? as a general rule of thumb, no interplanetary burn should take more than 12 hours.
