A Babylonian astrologer, working in the eighth century BCE, marks a cuneiform tablet. The red star has stopped its nightly drift eastward and begun to crawl west. He records it as a sign of Nergal’s displeasure. The god of war had turned his back on the world. That moment — the apparent reversal of Mars in the sky — is what we still call Mars retrograde. Direct motion, by contrast, is the planet’s normal forward path across the fixed stars. The key difference is that during retrograde, the planet’s energy is interpreted as turning inward, forcing delays, revisiting old conflicts, and re-evaluating action. Direct motion signals forward drive, clear aggression, and the outward push of will.
What Mars Retrograde Actually Means in Astrology
Mars retrograde is an optical illusion. Earth, moving faster in its smaller orbit, overtakes the red planet. From our vantage point, Mars appears to reverse direction for about 80 days. This happens every 26 months. In astrological terms, the retrograde phase is not a physical change but a symbolic one. The planet’s archetypal force, war, drive, anger, assertion, is no longer expressed outwardly. It turns back on itself.
Direct motion, the planet’s usual forward path, lasts roughly 22 months between retrogrades. During that period, Mars moves through the zodiac at an average of 0.5 degrees per day. Its influence is felt as initiative, competition, and the will to act. The shift from direct to retrograde is not a break. It is a reversal of direction.
Where the Retrograde Observation Comes From
The Babylonians were the first to systematically record Mars retrograde. Tablets from the second millennium BCE show calculations for the planet’s “stationary points”, the moments when it appears to pause before reversing direction. They named Mars after Nergal, the god of plague and war. A retrograde period was read as a withdrawal of divine favor. Wars were postponed. Kings delayed campaigns.
Ptolemy, writing in the second century CE in the Tetrabiblos, explained the retrograde motion of the outer planets through the epicycle model. He argued that retrograde periods intensified the planet’s nature because the planet was closer to Earth. For Mars, that meant more war, more bloodshed. The astrologer should warn the client to avoid conflict.
Medieval Arabic astrologers like Abu Ma’shar (787–886 CE) refined the timing. In his Great Introduction to the Science of the Judgments of the Stars, he assigned different meanings to the phases: the retrograde station, the direct station, and the middle period. The station was the most dangerous. The planet was fixed, stuck, like a coiled spring.
Renaissance astrologer William Lilly (1602–1681) in Christian Astrology gave specific rules for Mars retrograde in horary questions. “If Mars be retrograde,” he wrote, “the querent is not resolved, or the thing demanded is not yet ripe.” He used the reversal to indicate hesitation, regret, or a hidden enemy.
The human consequence was practical. A general would not march during Mars retrograde. A farmer would not start a new field. The sky told you when to wait.
What the Symbolism of Each Direction Carries
Mars direct is the arrow released. It is the forward momentum of the warrior, the athlete, the builder. In a natal chart, a direct Mars suggests a person who acts first and thinks later. Anger is expressed openly. Desire is pursued without hesitation. The glyph of Mars, a circle with an arrow pointing diagonally upward, captures that thrust.
Mars retrograde is the arrow drawn back. The energy is still there, but it is held. The warrior examines the target before shooting. In a birth chart, a retrograde Mars often indicates suppressed anger, internalized aggression, or a pattern of indirect action. The person may be conflict-avoidant, but the rage is stored in the body. Martial artists have noted that their practice is more about control during retrograde periods than about power.
The key symbolic difference is direction. Direct motion is the outward expression of will. Retrograde motion is the inward examination of that same will. One is not better than the other. They are two phases of the same cycle.
How Practitioners Work with Each Phase
We do not treat Mars retrograde as a curse. We treat it as a time to revisit old conflicts. During the retrograde period, we avoid starting new lawsuits, launching new ventures, or initiating confrontations. Instead, we go back to unfinished battles. We review old anger. We train in defensive forms, tai chi, fencing drills, wrestling, rather than offensive sparring.
During direct motion, we act. We take the initiative. We start projects that require aggression: a business launch, a physical challenge, a difficult conversation. The direct period is when we push through obstacles.
We also watch the house in which the retrograde occurs. If Mars turns retrograde in your seventh house (relationships), you may revisit old fights with a partner. If it is in your tenth house (career), you may reconsider a past professional conflict. The house tells you where the work is.
Mars Retrograde Compared to Other Planetary Retrogrades
Mercury retrograde happens three or four times a year. It is about communication, travel, and contracts. The energy is quick and mental. Venus retrograde happens every 18 months. It is about love, values, and money. The energy is slow and relational.
Mars retrograde is different. It happens less often and lasts longer. It is about raw will. While Mercury retrograde might cause a missed flight, Mars retrograde can cause a war. The stakes are higher. The corrections are more painful.
In the natal chart, a retrograde Mars is rarer than a retrograde Mercury. Roughly 9 percent of the population has Mars retrograde in their birth chart. These individuals often struggle with how to express anger. They may have explosive outbursts after long periods of silence. The direct Mars native, by contrast, expresses anger in real time.
What People Get Wrong About Mars Retrograde
The most common misconception is that Mars retrograde causes accidents. It does not. It causes a tendency toward rash decisions that lead to accidents. The difference is subtle but important. The planet does not reach down and make you crash. It presents a situation where you are more likely to act without thinking, and then regret it.
Another mistake is treating retrograde as always negative. It is not. It is a time for necessary internal work. A soldier who checks his gear before battle is not weak. He is prepared. Mars retrograde is that check.
Some astrologers claim that the planet’s influence is weaker during retrograde. That is false. The energy is concentrated, not diminished. It is the difference between a river running fast and a river running deep. Both carry water.
FAQ
How often does Mars go retrograde?
Every 26 months, for about 80 days.
How long does Mars retrograde last?
Approximately 80 days, from the first station to the second station.
What does Mars retrograde mean in my natal chart?
It suggests that you express anger and drive differently than most people. You may hold aggression inward and release it in bursts. You are often better at defense than offense.
Can I start a new project during Mars retrograde?
We advise against launching new initiatives that require aggressive forward momentum. Instead, use the period to revisit old projects, rethink strategies, and resolve unfinished conflicts.
Where to Go from Here
Mars retrograde is one of several planetary reversals that shift the tone of the sky. The same logic applies to the other planets, each with its own rhythm and domain.
