Mercury square Mars is a difficult aspect when it comes to synastry. On the other hand, the troubles caused by this aspect are surmountable and in some circumstances, even enhance a relationship.
Mercury is the planet of communication, making it a key planet when it comes to synastry.
Mars is the planet associated with conflict, which gives it the potential to cause problems in relationships.
Squares are tense aspects that also produce conflict. Yet, squares can generate attraction as well as conflict.
Mercury Square Mars in Synastry
Any Mercury-Mars combination in a synastry chart will produce a lively and energetic relationship.
Depending on the aspect and signs involved, the relationship will be exciting or volatile. Sometimes, it is both at the same time.
Such is the case with Mercury square Mars. This aspect certainly has the potential to be quite volatile. However, it also produces a strange attraction between the people involved.
This attraction is of an intellectual nature rather than a romantic one, though. This is a relationship in which two people can rarely agree on anything, but still seek each other out on a regular basis.
The image is of two life-long friends who spend most of their time arguing with each other.
The relationship will be the most volatile if the square occurs between Cardinal Signs, which are Aries, Cancer, Libra, and Capricorn.
It will be more fun and exciting if it occurs between Mutable Signs, which are Gemini, Virgo, Sagittarius, and Pisces.
If it occurs between the Fixed Signs, which are Taurus, Leo, Scorpio, and Aquarius, it can add an odd stability to the relationship. The two will still disagree with each other, but the disagreement will take on the flavor of a well-scripted and rehearsed play that is repeated over and over again.
The nature of this aspect will also vary based on the house position of Mercury and Mars in each other’s charts.

Man’s Mercury Square Woman’s Mars Relationship
Mercury square Mars is challenging in romantic relationships. It has similar features as Mercury conjunct Mars, in that he will annoy her when he tries to talk.
This aspect is a little easier than Mercury conjunct Mars, though, because the annoyance is conscious, rather than a visceral reaction. She will know what it is that annoys her and will generally be able to articulate it.
This aspect does produce chemistry, but as discussed above, it is not physical or sexual by nature. On the other hand, if it is combined with Venus aspects, it can enhance any sexual chemistry that is already present.
While this aspect is mostly considered difficult and challenging, there are those that like a little volatility in their romantic relationships. If both parties enjoy a little spice in their relationships, this aspect can provide just enough to make them happy.
For long-term relationships, however, it will be important to look at the other Mercury aspects between them to see if they have more harmonious ways to communicate.
Woman’s Mercury Square Man’s Mars Relationship
A woman’s Mercury square a man’s Mars can cause more problems with communication than when the genders are reversed.
In this case, the most common problem will be that he will not take the time to listen to her. Her communication style will annoy him, and he will most likely respond by finding things to keep him busy and ignore her.
If she pushes for more attention and communication, he is likely to respond by retreating further into his other activities.
This is not necessarily fatal to the relationship. Few couples spend all of their time together or even want to.
A lot will depend on the other aspects between their charts.
Other Mercury contacts or Venus contacts will go a long way towards providing more positive avenues for communication and togetherness.
Mercury Square Mars in Friendship
As mentioned before, the chemistry generated by this aspect is of an intellectual nature. This can be quite good for a friendship.
These friends will seek each other out for lively conversations. On the other hand, they will rarely agree on anything.
Even though they will talk a lot, they may not actually communicate with one another. At least on some level, they will see the world in fundamentally different ways.
Because of this, their friendship may not be very close on an emotional level. Much will depend on the other aspects between their charts.
It will be hard for these friends to hear advice from each other. On the other hand, the advice they give each other will generally be quite sound.
Friends with this aspect will tell each other things that most people will be too polite to tell them. They will see each other’s faults quite clearly.
Because of this, if they are able to hear hard truths, these friends can be quite valuable to one another.
