NASA's Perseverance rover, which is set out to find signs of ancient microbial life on Mars, has begun exploration on the red planet. In its first test drive, the rover went forward 13 feet, took a 150-degree left turn, then backed up 8 feet in its 33-minute movement. After the performance, a NASA engineer said, "We are now confident our drive system is good to go".
