Actually they have about 10 mini-satellites they will drop off at the moon or continue on to other destinations. Those will measure ration, check for water head out for an asteroid, etc. More details below.
Artemis I: About the CubeSat Payload
When Orion blasts off for the first Artemis mission next year, so too will several CubeSats in an effort to learn more about deep space.spacecenter.org
BioSentinel
"Then, there's BioSentinel, developed by NASA's Ames Research Center. This CubeSat is out to study how living organisms are affected by deep-space radiation. This 18-month mission, which utilizes yeast to assess the effects of deep-space radiation, marks the first time in over 40 years that living organisms have been sent to deep space. The findings of this experiment will ultimately serve to protect humans on future exploration missions."
So a long time from now, far, far away, some alien civilization will discover a shoe box full of yeast, and wonder how such seemingly dumb organisms could figure out how to make a spacecraft.
