Mars stations retrograde in Libra on March 1st, putting the brakes on the already less direct planet of action and aggression. I say "less direct," because Mars in Libra makes no moves without balancing impulse with social consequences. There is still movement, but once Mars is reversed, I think we can expect no external movement.
But that doesn't mean no progress. As with all retrogrades, this one is about reevaluation and internalization. There will be a lot of stopping and pondering recent initiatives (in the context of the natal house that Mars is moving through). Actions that impact others (Libra) will be under the microscope, as will issues around expressing and asserting sexual desires. Libra is the mirror, and Mars in Libra has been about projecting outwards. Objective action. Once Mars goes Rx, it will become subjective; people will be looking at the results (so far) of their actions.
Another way to look at it; you throw the ball (Mars) to someone, and see if they catch it. That's Mars direct. With Mars Rx, they throw the ball back to you , and you hold onto it for awhile. Or, they drop the ball and you walk over and pick it up. Now you've got this ball in your hand, what's the next move? Throw it again? Maybe toss it to someone else.
When Mars stations Rx, it will be one degree past a square with Venus in Capricorn (Venus will be at 26 degrees, Mars will be at 27). The square will be exact on March 2nd (when Saturn goes Rx) as Venus moves ahead to 27 degrees. March 1st and 2nd will feature some tension, as delayed/reconsidered actions (Mars) challenge the desire for concrete proof of love/attraction/resources (Venus). People may not quite get what they want (in relationships, money or success). But still...this is creative tension. There will be a prompt to find another way, or make adjustments. This time, you may have to backtrack, withdraw or even bow out. Whatever you do, don't push. Yes, this upcoming square will happen during the New Moon in Pisces, but it won't be a major component. More like a thread that supports the bigger theme of slow down and ease into the new chapter.
Remember January 13th to 16th? That was another Venus in Capricorn/Mars in Libra square, but Venus was Rx that time. Different degrees as well, so this square won't bring up exactly the same issues, but I think many people will be revisiting a similar theme.
Direct, impulsive action or pushy insistence will get you nowhere during Mars Rx. But this is a time for serious reflection on what you take from others, what they take from you, or how you assert yourself. Inappropriate moves may also come back to bite a few people; the social boomerang.
Mars will Rx from 27 to 9 degrees Libra before going direct on May 19th. If you have planets/angles/Nodes (natal or Progressed) within these degrees, (in Libra, Cancer, Aries or Capricorn) you'll probably be revisiting some specific issues. But everyone will feel the slow down.
