Mercury trine Mars is a helpful aspect in synastry.
Mercury is an important planet when it comes to relationships because it governs communication.
Mars governs how we express anger. It also governs how we go about getting what we want and how we get things done.
A trine is a harmonious aspect. In most cases, a trine will bring out the best of both of the planets involved.
Mercury Trine Mars in Synastry
In any relationship that involves accomplishing goals and tasks, Mercury trine Mars is a great synastry aspect to have.
This aspect is also helpful when it comes to negotiation and conflict resolution.
People with this aspect between them are able to talk about their thoughts and ideas about how to get things done. They can also talk about things that upset them in their relationship.
Because of this, two people with Mercury trine Mars can go a long way towards being able to work through whatever challenging aspects they may have in synastry between their charts.
Several sign combinations will change the meaning of this aspect based on the strength or weakness of Mercury and Mars in these signs.
Mercury in Capricorn/Mars in Virgo
This is the most positive sign combination for this aspect. Mercury rules and is exalted in Virgo and Mars is exalted in Capricorn.
This situation is known as mutual reception. In combination with a trine, it creates a deep affinity between these planets.
When these two work together, they can accomplish anything they set out to do. This is especially the case as both Capricorn and Virgo are Earth Signs.
Mercury in Virgo/Mars in Capricorn
In this situation, both Mercury and Mars are strong. This will increase the help that they are able to give each other when they work in harmony.
This is a very productive combination.
Mercury in Gemini/Mars in Libra
In this case, Mercury is strong and Mars is weak.
Mars has a hard time acting directly in Libra. Libra is the sign of the peacemaker, which frustrates Mars, who is a warrior by nature. People with Mars in Libra are prone to using manipulation and passive-aggressive behavior.
Mercury in Gemini will be very helpful to Mars in Libra, in that Mercury will understand what Mars is trying to do. Because of this, Mercury will be able to help Mars communicate in a healthier and more direct manner.
Mercury in Virgo/Mars in Taurus
This is another situation in which Mercury is strong and Mars is weak.
It is hard for Mars to find expression in Taurus, who prefers to be quiet and calm. This often results in Mars holding in its anger and holding grudges.
Mercury in Virgo can help Mars in Taurus talk about its anger and frustration.
Mercury in Pisces/Mars in Scorpio
In this case, it is Mars that is strong, and Mercury that is weak.
Mercury in Pisces has a difficult time in giving form to its ideas and imaginings. Mars in Scorpio will help give Mercury in Pisces the initiative and the direction to turn its dreams into reality.
Mercury in Sagittarius/Mars in Aries
This is another situation in which Mars is strong, and Mercury is weak.
This is not as helpful as in the previous case of Mercury in Pisces and Mars in Scorpio. The reason for this is that Mars has some mild dignity in Pisces, but it does not have any dignity in Sagittarius.
Even so, this combination is still slightly more positive than other sign combinations in that it will give a special benefit to the person whose Mercury is in Sagittarius.
Mercury in Sagittarius can be blunt to the point of rudeness. Mars in Aries will not get annoyed with this. Indeed, Mars will tend to find this quality attractive.
Mercury in Pisces/Mars in Cancer
In this case, both Mercury and Mars are weak. Of the two, Mars is in better condition, but not enough to be helpful.
Because of this, Mercury trine Mars is much less positive than it is for most sign combinations. The benefits of this aspect will be faint and not very noticeable.
Mercury in Cancer/Mars in Pisces
Even though Cancer and Pisces are trine, Pisces rejects Mercury and Mars rejects Pisces.
This consideration will tend to cancel the positive qualities of this aspect. Indeed, in some ways, this aspect may behave like a very mild form of Mercury square Mars.
House Positions of Mercury and Mars
In addition to the special sign combinations, the house position of Mercury and Mars will modify the meaning of this aspect in synastry.

How to Tell if Mercury is Trine Mars in Synastry
Trines involve signs of the same element. This is why they get along so well together.
If someone's Mercury is in the same element as another's Mars, the influence of Mercury trine Mars will be present.
Below are the signs that are trine by element:
Trines are the most powerful and harmonious when they are within orb, which is the allowable margin of error. The orb between Mercury and Mars is seven degrees.
Mercury and Mars can be within orb of a trine from signs that are of different elements if one planet is at the beginning of a sign and the other planet is at the end. This is known as a "cross-sign" trine.
In the case of Mercury trine Mars, much of the harmony will be lost if the planets are not in the right signs, so the aspect will be very weak.
Mercury trine Mars is a wonderful aspect to have. Its primary benefit is that it allows two people to work very well together.
Although this aspect is generally positive, it can be modified by the signs involved. Certain sign combinations will enhance it and others will weaken or even sour its influence.
