Mars is activity and will activate whatever 'house' it is in or wherever Aries appears on your chart. These will be the departments of your life where you participate. Mars also brings trouble and arguments to these areas. Sometimes you are too quick in these areas and don't stop to think or give others a chance to keep up with you. Mars in the third house, for example, would mean that you like to pass all the other cars on the road.

Mars can be physical participation or mental participation, depending on the sign or house it is in. An air sign tends toward mental participation. Mars will fight for what it wants, again, physically or mentally.

This is the area of your performance, your accomplishments, and the manner in which you handle them. It is the direction in which your energy travels, what kind of energy you have, and what you want the energy to do.

Mars rules the sign Aries and therefore retains all the characteristics of that sign as well as of the first solar house.

Mars rules weapons (such as guns or knifes), cars (along with the planet Mercury), the army (or other ground fighting force), athletics, and in general all physical activity and motion.
