We have no idea what they are
You can see slope streaks on the red planet, but what do the lines on Mars really mean? Where do they come from? There are a lot of guesses about what caused the streaks but scientists honestly don't know what has made the streaks appear on Mars. Some have guessed that they were made with water or something "wet," while others guess at something dry, but we're still playing guessing games.
Some of us think we'd better hurry up and make a Mars field guide if humans are expecting to make the planet home anytime soon. Hopefully AOC and the rest of the Democrats can get their New Green Deal together and help save this planet for us.
What do you think has caused the unusual patterns on Mars? Share your ideas in the chat.
