Mars is ready for another close-up. For the second time in nearly 60,000 years, the Red Planet will swing unusually close to Earth this weekend, appearing as a yellow twinkle in the night sky. Mars’ latest rendezvous will not match its record-breaking approach to Earth in 2003, when it hovered from 35 million miles away. But more skygazers this time around can glimpse the fourth rock from the sun because it will glow above the horizon.
