    Spaceship travel to Mars.
    This question is about space travel. If possible to use, how much hydrogen or/ and nuclear fuel would be needed to fuel a spaceship travelling to Mars from Earth. Let's say the spaceship weighed 800 tons maybe for 6 people or so. And how much time would it take for each fuel type spaceships to travel to Mars from Earth. The answer would be most helpful.

    Erm, this is quite a hard to calculate question, what kind of payload do you want to take to mars? Just the fuel? How much do the engines weigh? There are too many variables here that you haven't defined to give you a good answer.

    Apologies, I didn't see that you had given information about the payload. However, I don't particularly feel like answering your question now you've given me a completely undeserved reddie.

    I was trying to work towards an answer for you, but if you don't wish to receive that help, then fair enough.

    Hey thanks for trying to answer my question. Yes I had provided the payload but that doesn't necessarily matter. I need to know an approximation of the process, it doesn't really have to be accurate. If you could figure it out, I think it could be quiet knowledgeable for a general perspective on space travel.

    Look up the following topics and see if you can piece it together yourself (more help will probably come for your future questions if you are more friendly). You'll find that the internet has already answered most questions in life if you just look :)

    Energy required to enter orbit from earth
    Energy capacity of your various fuels
    Efficiency of engines using your various fuels
    Distance from earth to mars
    Maximum tolerable long term and short term acceleration for humans

    That'll probably be enough for you to put a rough sketch together that will help estimate your answer.
