Mars has fascinated scientists for decades. Robotic missions have provided valuable data about the planet’s surface and climate.
NASA’s rover Perseverance is currently exploring Mars. It collects rock samples and searches for signs of ancient microbial life.
Scientists believe that billions of years ago, Mars had liquid water. If water existed, life might have existed too.
Future missions may bring Martian samples back to Earth. Eventually, humans may attempt to land on Mars and build research bases there.
