This is what I have to do:
Imagine that you are in a spacecraft on a mission to Mars that will take several years. Write an e-mail letter to a friend describing the first two weeks of the year-long journey to Earth.
Include some scientific basis.
So, can you guys please help me with some peices of scientific based information.

You didn't give us the grade you are in, but well, he's some things to consider....
It is going to take several years to reach Mars so you probably have to grow your own food and have an in-built water-recycling system. Also, due to the fact that the human body is not very well adapted to zero-gravity environments, your spacecraft has to have a gravity simulator. You can write about the greenhouse where all your food is grown and how the environment is controlled, etc. You can also write about how you go about cleaning yourself and your belongings. The crew quaters and the fact that bunkers would be a bad idea, in case the gravity simulator has a technical probelm. You'd probably sleep in sleepings bags.
In the missions undertaken so far, frozen food is provided that needs no cooking process. But this won;t be the case on a mArs mission. You can probably do some research on how the kitchen setup should be so that accidents are avioded and also minimum amount of oxygen is wasted by the stove.
These are just points dude, build up on 'em!! Chio!!

Information on MARS:
MARS has two moons: Deimos and Phobos.
Phobos orbits around the planet Mars in 7 hours and 39 minutes.
Deimos takes 4 times as long to complete one orbit around Mars.
Both moons are dark rocky object. Deimos is 9.3 miles long (not a sphere) and Phobos is 16.6 miles long (also not a sphere).
Mars makes one complete orbit around the Sun in 687 Earth Days. It also spins around on its own axis in a bit more than 24 Earth hours (24.62), so the duration of a day on Mars is a little bit longer than here on Earth.
The diameter of Mars is 4, 220 miles (as compared to 7,926 miles diameter for the Earth).
The temperature on the surface of Mars varies between -195
degrees F and +77 degrees F. So one might consider the temperature to be downright cold at night and not bad in the daytime. The surface features of Mars are formed of mostly sandy rock with all the heavy metals deep under the soil in the core of the planet.
The axis of Mars' rotation is tilted about 25 degrees from its plane of rotation around the Sun, so like the Earth, it also has summers and winters.
The northern hemisphere of Mars is covered by mostly smooth low lying volcanic plains. The southern hemisphere is much older and consists of crater covered highlands and ridges. One complex canyon system on the surface of Mars called Valles Marineris is over 2500 miles long. Several huge volcanic peaks also may be seen on the surface of the planet. Olympus Mons is the most significant of these and is almost 15 miles high.
In a way similar to Earth, Mars has water in polar ice caps. The recent space probes to the planet have determined that those ice caps are about 7 1/2 miles wide. No running water has been found on other places on Mars as yet.
