This launch will be an uncrewed test, so no astronauts will be aboard. However, there are a few items going along for the ride.
According to NASA, several of the cargo lockers on board the capsule will contain 'commemorative' items:
One of the lockers carries a radiation experiment designed by the students who won the Exploration Design Challenge, an initiative for students to research and design ways to protect astronauts on future missions from radiation. Another radiation experiment designed by NASA called BIRD, for battery-operated independent radiation detector, will evaluate the environment inside the locker as Orion passes through the Van Allen belts experiencing higher doses of radiation than spacecraft that orbit closer to Earth, such as the International Space Station.
Several artistic works commissioned by Lockheed Martin will be aboard, including a recording of "We Shall Overcome" by Denyce Graves arranged by Nolan Williams. The arrangement features the words "We Shall Live in Peace," a theme common throughout America's civilian space program and efforts. Several poems by poet Maya Angelou will also be aboard, including “Brave and Startling Truth.” A recording of "Mars" from Gustav Holst's "The Planets" performed by the National Symphony Orchestra will also be carried on Orion, along with a copy of a poem by Marshall Jones and a small sculpture by Ed Dwight called “Pioneer Woman.” The works will help expand the cultural connection between the arts and science.
The flight test also will carry several items that will be used to inspire future generations. NASA and Sesame Street have joined forces to help promote the importance of studying science, technology, engineering and math (STEM) and teach students about the importance of human spaceflight. Cookie Monster’s cookie, Ernie’s rubber ducky, Slimey the Worm and Grover’s cape will fly some 3,600 miles above Earth and come back to take prized spots on the Sesame Street set where millions of children will watch.
