1.If you want to send a spacecraft to Mars, you'll want to have a speedy rocket to escape Earth's gravity.The heavier stuff inside of the rocket the more powerful your ship needs to be.
2.Next, make sure the earth is lined up with mars so that you wont have to travel as far. if you miss this opportunity then you will be waiting another 2 years.
3.Finally, make sure your aim is right. You can't shoot for where Mars is at launch time . You will have to aim where it will be.

Mars is a very special planet, this is because Mars is wider than it is taller. The equator circumference of Mars is 6,792 km and the polar diameter of Mars is 6,752 km. Mars has 2 moons and their names are Phobos and Deimos. Mars' distance from the sun is 227,943,824 km or 1.52AU. The surface temperature of the red planet can be from -153 degrees to 20 degrees. The orbit time for Mars is 687 days which is 1.9 years. This was all recorded by Egyptian astronomers in the 2nd Millenium BC. Mars is predicted to be about half the size of the Earth.

The atmosphere on Mars is made up of mainly carbon dioxide (95.3%). The martian atmosphere is approximately 96% carbon dioxide, 1.9% nitrogen and traces of free oxygen, carbon monoxide, water and methane , among other gases, for a mean molar mass of 43.34 g/mol.

Astronauts could use Mars' resources to grow food. Mars' atmosphere consists mostly carbon dioxide, an essential gas for plant survival, martian soil has the essential nutrients that all plants need to survive, but depending on where astronauts land the ability to grow crops might be quite hard.

There is evidence that water exists in some of Mars' soil and atmosphere. Astronauts may be able to actually extract so they can drink it. Scientists have looked at perchlorate, a type a salt that contains the ion CLO4, and is present all over Mars. Perchlorate sucks up water out of the air, and astronauts could extract the water present in Mars' perchlorate.

Because Mars is farther away  from the sun than the Earth, so the red planet is very cold. The sunlight and heat is a lot less than the Earth would ever get. Also the atmosphere  is a lot less thick than what you would think. The warmest place on Mars is the equator, like the Earth. so if you were to set up camp on the red planet, you would want to set up on the equator.

The gravity on Mars compared the Earth is only about 38% less than our planet. If you only weight about 100 pounds then on Mars you will only weigh 38 pounds.
