Meaning of Mars in astrology
Mars is the planet of action, desire and energy. It represents the force that drives us to move, to pursue what we want, to defend ourselves and to transform the world. While Venus attracts, Mars pursues; while Venus values, Mars conquers. It is the active masculine principle, complementary to the feminine lunar and the venusian attractive.
In astrological tradition, Mars rules the sign of Aries and, in its most ancient and dark aspect, also Scorpio. Its natural house is I, that of self and action. Its metal is iron, its color red, its season the beginning of spring when life bursts forth with force. Mars also rules male sexuality, sport, competition and the capacity for struggle.
Mars in the signs
The sign Mars occupies describes your style of action and your way of pursuing desire. A Mars in Aries acts with impulsiveness and bravery, shoots the arrow first and asks later; a Mars in Taurus acts slowly but with unstoppable force, defends its territory with tenacity. Mars in Capricorn is exalted: it disciplines energy and turns it into lasting achievement. Each sign gives Mars a different warrior flavor.
Mars in fire signs (Aries, Leo, Sagittarius) are the most energetic and enthusiastic; those in earth, the most patient and persistent; those in air, the most mental and verbal; those in water, the most emotional and intense. Mars takes about two years to traverse the zodiac, spending approximately two months in each sign, which makes its position quite specific to the moment of birth.
Mars in the houses
The house where Mars falls indicates the life area where you invest your energy, where you fight and where you seek to conquer. A Mars in House I gives a present physical body and a personality that imposes itself; in House VII, energy is poured into partnerships; in House X, into career and public ambition. This position reveals where you are most combative and where it is hardest for you to yield.
The martian house also shows where you may have conflicts, where you get frustrated when something blocks you and where you need to express force. It is the territory where aggressiveness can be creative if channeled well, or destructive if repressed. Identifying Mars's house is therefore essential to understand where the person invests their vitality and where they can find their main battlefield in life.
Aspects to Mars
The aspects Mars receives deeply nuance how energy and anger are experienced. A Mars trine Jupiter gives enthusiasm, optimism and the ability to undertake great projects; a square with Saturn introduces frustrations, blocks and the need to learn discipline. Each aspect is a dialogue between the martian principle and another planetary energy that modifies it.
Mars's best-known aspect is the conjunction with Venus, which describes the chemistry between masculine desire and feminine attraction. Another important aspect is Mars-Saturn, which indicates the ability to channel force into lasting work. Mars aspected by Pluto becomes magnetic and transformative; aspected by Uranus, explosive and unpredictable. Studying martian aspects is key to understanding how the person expresses their will.
