The sign in which Mars resides in the birth chart shows the expression of energies. Mars suggests the projection of self. Your energies must be evaluated in four different ways, and the sign that Mars occupies at birth largely signifies the type and degree of energy in all four. These four are first, Physical energies, which might show how hard or diligently you work, aptitude for sports, and just generally having the go power to get what you want in life. Next is mental energy; the energy spent thinking, communicating, and pursuing intellectual goal and ambitions. Then, comes the practical energy that is necessary to make your way in life; planning and organizing, holding down a job and padding the old nest egg, being responsible and dependable. Finally, Mars defines emotional energies which usually show up first as sex drive, but may include other aspects of emotions such as feelings, and setting emotional boundaries, and drive toward artistic endeavors. The Mars position suggests whether your energies are going to be largely physical (fire signs Aries, Leo, Sagittarius), material (earth signs Taurus, Virgo, Capricorn), mental (air signs Gemini, Libra, Aquarius), or emotional (water signs Cancer, Scorpio, Pisces). Here then is Mars in the twelve signs:

Aries

Mars is at its strongest in Aries, its natural sign. This placement represents high energy, initiative, courage and impulsiveness. Most of the energies seem to come out as the physical and emotional type, but in Aries, Mars is very active and assertive in demonstrating enthusiasm for all four types of energy. This is a very powerful position for Mars.

You have an unrestricted drive to get projects done, to start new projects, and to act decisively. Your enthusiasm is contagious. An individualist with quite an ego, you always want to do things your way. Based on the influence of this planet taken by itself, you are not good at compromise or teamwork. There is a major part of you that always wants to charge out ahead of the pack and be the leader. Despite your apparent leadership abilities, you may function best when you are working alone and independently because of your demand to have your own way. If you are in a group, you will aspire to be the leader. Headstrong and independent, you won’t tolerate opposition or interference and your temper can get you into trouble at times. Mars in Aries makes you very competitive in a variety of ways. This is perhaps the most courageous and enterprising Mars position.
You have a very strong sex drive which is spontaneous and easily aroused. Self-control can be a problems in this regard. As on the physical side, you are often unrestrained and very demanding emotionally.
The negative side of Mars in Aries is a lack of patience and discipline. Self-control and humility can be hard lessons, and often they are never mastered.

Taurus

Mars in Taurus denotes plenty of practical and emotional energy, while the physical side is often rather flat, and the interest in the intellectual is also a strain.

The planet of energy is not very active in Taurus, as the physical drive is reduced to a low gear. You may lack thrust and mobility, but make up for this deficiency with outstanding endurance. You are obstinate in many ways, yet practical, determined and very stable. You pursue your material goals with intent determination. Results are based on dogged persevering after a course of action is determined. Once you finally get rolling in one direction, it is nearly impossible to change your course. In Taurus, the energies of Mars are indeed channeled into a practical mode that may center on acquiring money, creature comforts and material possessions. Much your energy is apt to be aimed at securing wealth and a very comfortable lifestyle. Patient and precise in all that you do, you are a natural crafts person and the fruit of your efforts is likely to produce a quality product.
Also high on your list of priorities is the satisfying of physical desires. You are very sensual and sexual partner. Your approach to sex is straightforward and uncomplicated, without fantasies or fetishes; never rushed or over-anxious. Emotionally stable, you are apt to be a devoted and loyal partner.
The negative side of Mars in Taurus is often the lack of flexibility. Taurus is a fixed sign and energies expressed here sometimes come out looking like stubbornness. Even emotions can be held on to too tightly and then released with a major blow up.

Gemini

In Gemini, Mars produces mental assertiveness and mental energies are highest here. As wonderful as this seems, on the practical side, you may be somewhat lacking, and emotionally, this placement is prone to big swings and is best defined as erratic.

Mars in Gemini is high-strung and produces much nervous energy, but it is lacking in physical vitality or endurance. There is a tendency for you to burn yourself out through stress and mental strain. You may need to force yourself to get more exercise as a way of balancing the physical with the mental.

Cancer

In Cancer, the Mars energies are largely of the emotional sort. While physical endeavors and practical affairs may find the energy to function satisfactorily, mental energies are apt to struggle.

This placement often causes actions to be tinged with a very sensitive flavor. You express your energies in a very emotional fashion. Much of the assertiveness of Mars is turned toward the domestic scene. There is a cautious side and much defensiveness in your nature. This placement of Mars is not very physical or competitive, and not inclined to any sort of combat, physical or mental. Mars in Cancer has a very positive side, as it often shows a quiet, peaceful nature. While being very protective of your “turf,” you are never too assertive or demanding. In your work, you rarely compromise your views, and prefer working independently and in control of affairs. You are ambitious, and a hard worker. Since you are not, by nature, an aggressive person, you pursue your desires in a round-about or start-stop manner. You frequently change your direction and your goals. You strive for security, and a good deal of your energy goes into this effort. In this regard, you are fiercely protective of family, co-workers, organization, or to whatever you devote yourself. You may be known for the strength of your patriotism and loyalty.
Because of these strong moods and feelings, you are a very sexual and sensual person. You are also very loyal in relationships, and certainly demanding of the same from your partner. Infidelity threatens your sense of security and is therefore unacceptable.
