CAPE CANAVERAL, Fla. — NASA test director Jeff Spaulding does not want to hear jokes on April Fools' Day. He doesn't want pranks. He just wants to send people to the moon.

This is not a punchline. NASA is counting down to launch four astronauts around the moon on Artemis 2, a 10-day trip that will lift off a bit before sunset tomorrow, which is April 1 — a holiday for pranksters. But NASA is staying serious.
