In Your Birth Chart
Mars is the part of you that gets out of bed when you'd rather not. It's your competitive streak, your temper, your sex drive, and the way you slam the car door when you're angry. Mars is desire, but not the kind that sits around waiting—the kind that moves. It's how you go after what you want, how you fight when you have to, how you handle conflict when it's unavoidable. Some people have a Mars that fights directly. Others have a Mars that goes quiet and cold. Neither is wrong, but both have consequences. Mars is also your physical energy—whether you're restless or steady, whether you need to move or you're fine sitting still. The house Mars occupies is where you're most likely to take action, where you're willing to fight, where you're learning to assert yourself without destroying everything in the process. It's also where you're most easily provoked.
As a Transit
Mars spends six to seven weeks in each house, and during that time, that area of your life speeds up. You're more motivated, more impatient, more willing to start things. It's a good time to tackle whatever you've been avoiding in that area because you'll actually have the energy to deal with it. Mars transits bring action, but they also bring conflict. If there's a problem in that house, Mars will make it obvious. People are more direct, which can be refreshing or exhausting depending on the day. Mars doesn't do subtlety. It doesn't wait. If you've been sitting on a decision, a Mars transit will force your hand. The energy is there—use it before it turns into frustration or anger. Mars moves faster than the outer planets but slower than the inner ones, which makes it useful for timing. You have about six weeks to get something done. That's enough time to make real progress if you don't waste it.
Positive Expression
You know what you want and you go get it. You don't wait for permission. You handle conflict directly and then move on. You're brave when it matters. You protect people who can't protect themselves. You're physically capable and you use that capability well. You're passionate without being destructive. You finish what you start.
Shadow Side
You're aggressive and you call it honesty. You pick fights because you're bored. You're so focused on winning that you don't notice you're hurting people. You're impatient and you make everyone else rush. You're selfish. You use your anger as a weapon. You start things and don't finish them. You're reckless and you expect other people to clean up the mess.
When Retrograde
Mars goes retrograde every two years for about two and a half months, and it feels like trying to run through water. Your energy drops. Your motivation disappears. Things that should take a week take a month. Mars retrograde is frustrating because Mars is the planet of action, and when it's retrograde, action becomes harder. You start projects and then lose interest. You pick fights you don't care about. You're angry but you don't know why. The advice is to slow down, which is the last thing you want to hear during a Mars retrograde, but it's the only thing that works. Don't start new projects. Don't pick fights. Don't make big moves. Use the time to finish what you started before the retrograde. Mars retrograde is also when old anger comes back—situations you thought you were over suddenly feel fresh again. That's the retrograde asking you to deal with it properly this time.
Orbital Facts
Mars is the fourth planet from the Sun, orbiting at about 142 million miles. It takes 687 Earth days to complete one orbit, which is why Mars transits last about six to seven weeks per house. Mars is about half the size of Earth, with a thin atmosphere mostly made of carbon dioxide. The surface is red because of iron oxide—rust—which is why it's called the Red Planet. Mars has two small moons, Phobos and Deimos, which are probably captured asteroids. The surface is covered in canyons, volcanoes, and impact craters. Olympus Mons, the largest volcano in the solar system, is on Mars—it's 13.6 miles high, nearly three times the height of Mount Everest. Mars has polar ice caps made of water and frozen carbon dioxide. The temperature averages -80°F, but it can get as warm as 70°F at the equator in summer. You can see Mars with the naked eye, and it's noticeably red. Every two years, Mars and Earth are closest to each other, which is why Mars missions launch during those windows. Mars feels close because it is close—at least compared to the outer planets.
How to Work With This Energy
Tuesdays are Mars days, so use them for anything that requires courage or initiative. Have the hard conversation. Start the project. Go to the gym. Mars likes movement, so if you're feeling stuck or angry, move your body. Run, lift, dance, punch something that's designed to be punched. Mars energy that doesn't get used turns into frustration or passive aggression, and nobody wants that. If you want to work with Mars intentionally, figure out where it is in your chart and focus your energy there. If it's in your career house, that's where you should be pushing. If it's in your relationship house, that's where you need to be direct. Mars doesn't do half measures. It wants full commitment or nothing. Mars transits are also good for sex, competition, and anything that requires physical courage. If you've been avoiding something because it's scary, wait for Mars to transit the relevant house and then do it. You'll have the energy. Mars also governs tools and weapons, so if you're learning a new skill that requires physical coordination, Mars transits help.
