This is a carousel. Use Next and Previous buttons to navigateScientists are going to attempt something in the next few weeks that no one has ever done. They're going to fly a helicopter on Mars.The robotic aircraft is named Ingenuity, and its core is about the size of a softball. For the past seven months, the device has been rocketing toward the Red Planet inside a rover called Perseverance. After traveling at nearly 25,000 miles per hour, they are scheduled to touch down on Martian soil Thursday.
