Mars stands for drive: desire, assertion, courage, and how you fight. It rules aries (and Scorpio by traditional rulership): starting, and digging. Astronomically it is the red planet, Earth's outside neighbor, target of every rover we've sent.

The astronomy, briefly
Astrology ignores almost nothing about the sky, but it does sort bodies by how fast they move. Mars takes about 2 years through the zodiac. That pace matters: fast bodies describe personal, day-to-day patterns, while slow ones describe whole generations. When someone says “everyone my age has Pluto in the same sign,” this is why.
Reading Mars: the three questions
Every placement answers three questions. What is it (the planet: here, Mars)? How does it behave (the sign)? Where does it act (the house)? Take Mars in Leo, the receipt above. You would read the function (drive) in Leo's style, and then look up which house it occupied that day for that observer. Same planet, different story per person. The house is why two people with the same placement can live it differently.

FAQ
What does Mars mean in a birth chart?

about 2 years through the zodiac. That pace is why some placements feel personal (fast bodies like the Moon) and some feel generational (slow ones like Pluto, which a whole cohort shares).
