200 years has passed and now it is year 2220. The Earth is out of basic resourcesas they have been drastically drained in the past 200 years. The president of theUnited World Council (UWC) has approved you and your crew’s Mission toMars. You will pilot the most advanced spaceship the world has ever known, theExcelsior! It will carry equipment that will help to transform Mars so as toresemble the Earth, especially so that it can support human life.Before the mission can launch a few items need to be figured out. What is thecapacity of the fuel tank? How long should the fuel burn to achieve escapevelocity (otherwise the Excelsior will be stuck in the Earth’s gravitational pull)?How long will it take the Excelsior to arrive at Mars?1. The ground crew is filling the fuel tanks. You know th

Answers:
A.
a few astronomers believed that they saw evidence of an intelligent civilization on Mars.
B.
Mars has seasons just like the Earth and therefore should be inhabitable by humans.
C.
Mars has an unusual surface color and global dust storms, creating strange weather patterns.
D.
Mars has unusual orbital properties making our understanding of its motion around the Sun very difficult.
where do you think we should establish a colony first? In Mars or in Moon?
