Alright, so let’s talk about this whole “Mars square Mercury” thing in synastry. You know, I’ve been messing around with birth charts for a while now, trying to figure out what makes relationships tick. And this particular aspect, where Mars and Mercury are at a 90-degree angle in two people’s charts, it’s a real head-scratcher.
So, first off, I pulled up the charts of a couple I know. Let’s call them, uh, Alex and Taylor. They’re always bickering, you know? It’s like they can’t have a normal conversation without it turning into a debate, or worse, a full-blown argument. I had a hunch something was up with their charts, so I dove in.
I started by checking where Mars and Mercury were in each of their charts. Mercury’s the planet of communication, how we think and talk. Mars is all about action, drive, and yeah, aggression. When these two are square, it’s like a mental battleground.

Turns out, Alex has Mercury in, say, Gemini – a sign known for being chatty and quick-witted. Taylor’s got Mars in Virgo, which is all about being critical and detail-oriented. And yep, these two were square each other in their synastry chart. No wonder they’re always at each other’s throats!
Here’s what I did next: I made a list of all the times they’ve had major blow-ups. I’m talking about the big fights, the ones where they’re not speaking for days. Then, I compared those dates to their astrological transits. I wanted to see if there were any patterns, like maybe when Mars was transiting a certain sign, or when Mercury was retrograde, things got worse.
And guess what? There were some clear correlations. It seemed like whenever Mars was in a sign that squared their natal Mercury placements, or when Mercury was retrograde, boom! It was like a ticking time bomb.
Here is my observation log:
- First observation: I looked at their charts individually and noted their Mercury and Mars placements.
- Second observation: I charted out their major arguments and compared them to astrological transits.
- Third observation: I identified patterns, such as Mars transits triggering conflicts when aspecting their natal Mercury.
What I’ve Learned So Far
This Mars square Mercury aspect in synastry, it’s like having a constant internal struggle between thinking and acting. In a relationship, it manifests as arguments, misunderstandings, and a general sense of friction. It’s like both people are always on edge, ready to pounce on any perceived slight.
But it’s not all doom and gloom. I’m starting to think that understanding this aspect can actually be helpful. If Alex and Taylor, for example, were aware of these triggers, maybe they could learn to navigate their differences better. Like, when they feel a fight brewing, they could take a step back, recognize the astrological influences at play, and choose to respond differently. Maybe take some time alone, or try writing out the differences.
I’m still working on this, but I’m starting to see how astrology can be a real tool for understanding relationships. It’s like a roadmap, showing us the potential pitfalls and the best routes to take. This Mars square Mercury thing, it’s a tough one, but I’m determined to figure it out.
I’m not a professional relationship advisor, much less a professional astrologer, but these practices are very interesting to me. I’ll keep digging, and I’ll definitely share more as I uncover new insights. It’s a messy, complicated process, but hey, that’s what makes it interesting, right?
