1. The fourth outermost planet of the Terran-Solar-System. Mars is nicknamed the "Red Planet"; It's red color is the result of great amount of iron oxide FeO2 (rust) in the planet's soil. Mars is a cold, dusty, dry place. Water exist only in frozen caps at the poles. Simple life may have once lived there when it was warmer and wetter. Mars has a very thin atmoshphere which does not protect it well from radiation or meteors. Mars is named after the Roman go of war (the Greek god was Ares)

Where we are going to have to move to if Earth keeps on going the way it is right now.
Person 1: Earth is so corrupt that we have to move to Venus!

Person 2: Venus is too hot, we'll have to move to Mars instead!

Added to the end of a sentence instead of "not". Basically makes the sentence prior to 'mar' mean the opposite.
Person A: poor joke
Person B: lol mar

denotes that Person B does not in fact find the joke humorous

"I like your haircut mar"
This person does not like the haircut. In fact, they probably think it is ridiculous. 'mar' is used instead of 'not' as it is much less commonly known.

The First and best movement of Gustav Holst's Planet Suite. You kind of get a feeling when you listen to it to pick up a weapon and go to war.
Mars is the most amazing planet because of the two euphonium solos.
