While no humans will be aboard NASA's Artemis I mission, the Orion spacecraft won't be empty. Snoopy, Girl Scout badges, LEGO minifigures and tree seeds are just some of the thousands of mementos that will be aboard when the mission launches Monday.

There will also be a lot of technology that will gather data during the 42-day, 1.3 million-mile mission that will take the uncrewed spacecraft as far as 280,000 miles away from Earth, circling the moon before heading home.
