Red Planet: Mars, often called the "Red Planet," gets its nickname from the iron oxide, or rust, on its surface. This gives Mars its distinctive reddish appearance and makes it a captivating object in our night sky. Mars Exploration: Scientists and engineers have sent numerous spacecraft to explore Mars. One of the most notable is the Curiosity Rover, which has been diligently roaming the Martian surface, sending back valuable data about the planet's geology and atmosphere.
