The first unpiloted mission for NASA’s Artemis moon program aims to prove out the most powerful rocket to ever launch from U.S. soil, and test the function of a human-rated spacecraft traveling more than 40,000 miles beyond the far side of the moon before blazing back through Earth’s atmosphere at nearly 25,000 mph.
