You can't tell the direction of Mars from Earth in a simple way like "north" or "south." Here's why:

* Mars orbits the Sun: Just like Earth, Mars travels around the Sun in its own orbit. This means their relative positions constantly change.

* Earth's perspective: Our view of Mars depends on where we are in our own orbit. If Mars is on the opposite side of the Sun from Earth, it appears in the opposite direction of the Sun in the sky.

To find out the direction of Mars, you need to know:

* The current date: This will tell you where both Earth and Mars are in their orbits.

* Use a stargazing app: Apps like Stellarium or SkySafari can show you the current position of Mars in the night sky relative to your location.
