Moon trine Mars is a mildly positive aspect in synastry. It will support other positive aspects, and it will mitigate difficulties caused by challenging ones.
The Moon does not have a direct association with relationships in astrology. It is one of the Luminaries, however. As such, it plays a role in every aspect of life.
Mars is associated with conflict, which is a part of relationships. It also shows how we go after what we want.
A trine is the most harmonious aspect in astrology. In synastry, it highlights areas in which two people get along.
Moon Trine Mars in Synastry
Even though Moon trine Mars is a positive aspect, when it comes to synastry, it does not confer compatibility by itself.
Like all the planets Mars governs a lot of different things, but it is also considered a malefic. This means that it only grudgingly confers benefits, even when it is in a positive aspect such as a trine.
Still, this transit can help to support other good aspects and to temper problematic ones. It does this by making it easy and comfortable for two people to do things together.
No matter what other problems exist between the two, they will be able to enjoy shared activities together.
Like many other aspects, there are certain sign combinations that will modify the meaning of Moon trine Mars.
Moon in Scorpio, Mars in Cancer
This is the nicest combination for this aspect, and it will confer compatibility by itself.
The Moon has difficulty in Scorpio but rules Cancer. Likewise, Mars has trouble in Cancer but rules Scorpio. This means that both people have troubles individually, but they can rely upon each other for help.
This creates a strong sense of interdependence, which will produce a strong bond and will help the two work through their personal difficulties.
Moon in Capricorn, Mars in Taurus
This sign combination is similar to the one above. The Moon struggles in Capricorn but is exalted Taurus. In a similar way, Mars is uncomfortable in Taurus but is exalted in Capricorn.
These two will be good for each other and will be able to help each other with their individual struggles.
This enhances Moon trine Mars and makes it even more positive.
Moon in Taurus, Mars in Capricorn
In this case, both people have strengths in their chart, as the Moon is exalted in Taurus and Mars is exalted in Capricorn.
Yet, Taurus rejects Mars and Capricorn rejects the Moon.
This will weaken the positive benefits of this aspect. It will not completely neutralize the benefits, though, especially if there are other positive aspects between the two.
Moon in Cancer, Mars in Scorpio
This is the weakest sign combination for this aspect. The Moon and Mars are each strong in each individual’s chart, but they have poor reception with each other.
In order for the two to get any benefit from this aspect, there will have to be a lot of other positive aspects between them.

They would also make great business partners.

How to Tell if the Moon is Trine Mars in Synastry
