Apollo vs. Artemis: What to know about NASA's moon missions

NASA's Apollo moonshots are a tough act to follow, even after all this time.

As four astronauts get set to blast off on humanity's first trip to the moon in more than half a century, comparisons between Apollo and NASA's new Artemis program are inevitable.

Artemis reflects more of society, with a woman, person of color and Canadian rocketing away from Florida's Kennedy Space Center.

But they won't orbit the moon like the world's first lunar visitors did on Apollo 8 back in 1968.

Instead, they'll play it safe and zip around the moon in an out-and-back slingshot like Apollo 13.
