NASA began the countdown Monday for humanity’s first launch to the moon in 53 years.

The 32-story Space Launch System rocket is poised to blast off Wednesday evening with four astronauts. After a day in orbit around Earth, their Orion capsule will propel them to the moon and back. There are no stops — just a quick U-turn around the moon. The nearly 10-day flight will end with a splashdown in the Pacific.
