MARS IS A crazy place. In recent years we've discovered some of the strangest things on the Red Planet: ice spiders, Swiss cheese terrain, and perfectly spiral-shaped lava tubes. And the more we explore our near planetary neighbor, the weirder the things we find get. NASA’s Perseverance rover has had a busy first month on Mars’s surface. Already, team scientists have determined that several of the rocks are chemically similar to volcanic rocks on Earth, and that wind and water have eroded some of them.
