Imagine that we discovered a new planet that has the potential to support life. This planet has plenty of water on its surface and carbon dioxide in its atmosphere, and a nice, comfortable temperature similar to Earth. The only difference is that this planet orbits a star that produces green light only. If we took some plants from Earth and planted them on this new planet, would our plants be able to grow?

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
