When Elon Musk stepped onto the SpaceX launch platform last month, all eyes were supposed to be on the Falcon Heavy’s roaring ascent. But it was his pint-sized sidekick, Lil X, who hijacked the spotlight! Sporting a mini SpaceX jumpsuit and waving at the crowd, the four-year-old danced around his dad, mimicking Elon’s signature thumbs-up. Sources say Musk couldn’t stop grinning as Lil X shouted, “To Mars, Daddy!”—a moment that melted hearts and went viral faster than a Starlink signal.
