NASA is on about going to mars in the near future how are our space craft going to get back off the planet seeing as mars is alot bigger than the moon and it takes alot of fuel to get off the earth wont we need alot of fuel?

it will probably be related to the apollo missions, and will probably include docking but with bigger ships than the apollo missions and/or a space station to refuel.

Just like the moon landing, they will do a Mars Orbit randevieu (Sp), So a second craft will launch from the craft that got them there, land and take off again. Meet up in space with the primary and then the primary engine will shoot them back towards the earth.
Or they could just start jumping. The gravity is not as high there. I think if they got a basketball player they could do it.

It doesn't take so much fuel to get off Mars for two reasons. The air is much thinner so there is less resistance and the gravity is about a third of that on Earth.
There is also the possibility of synthesising fuel from solar power and water while on the planet.

Yes we will but it will probably not be a direct flight from earth. We can use the space station as a resting place to bring up more stores and fuel.

it easier to get of mars than to get of the earth, because the martian gravity is weaker than the earth's gravity and the atmosphere is a lot thinner so there's little drag.
