In one of the biggest April Fools’ jokes in decades, NASA is pretending once again to actually be going to the moon.

NASA has reportedly spent hundreds of millions of dollars on the elaborate prank, going so far as to construct a massive fake rocket on the Kennedy Space Center launch pad. As part of the joke, a green-screen video will be aired this evening of the “rocket launch”, featuring a tiny model rocket controlled by strings and employees making explosion sounds in the background.
