"People going up to the Moon is kind of cool," eight-year-old Isiah says.
He is among the 400,000 people expected to cram the causeways, beaches and motel balconies of Florida's Space Coast for the launch attempt of Artemis II tonight.
They will watch as four astronauts blast into space in the hope of flying around the Moon and potentially travelling further from Earth than anyone has ever been before.
Nasa's 10-day test flight will not land on the Moon. However, the crew may witness views of the lunar landscapes that have never been seen by human eyes.
Amanda Garcia has travelled more than 1,000 miles from New Mexico to witness the launch. "I'm pretty excited about it," she tells us.
