Mars rover Perseverance takes first spin on surface of red planet

NASA's Mars rover Perseverance has taken its first, short drive on the surface of the red planet, two weeks after the robot science lab's picture-perfect touchdown on the floor of a massive crater, mission managers said on Friday. The six-wheeled, car-sized astrobiology probe put a total of 6.5 meters (21.3 feet) on its odometer on Thursday during a half-hour test spin within Jezero Crater, site of an ancient, long-vanished lake bed and river delta on Mars.
