Sweetgum Tree Grows from Seed Traveled Beyond Moon in Texas
A sweetgum tree, planted at the University of Texas at Arlington, has emerged from a seed that orbited the Moon during NASA's Artemis I mission. The project aims to investigate the effects of space exposure on seed viability and plant growth, relevant for future life-support systems in space exploration.

The sweetgum tree in Texas results from a seed that traveled approximately 270,000 miles beyond the Moon as part of NASA's Artemis I mission, launched in late 2022. Planted on April 8, 2024, the tree has grown over four feet tall, part of a broader Artemis Moon Trees initiative collaborating with the U.S.
Department of Agriculture Forest Service to study seed responses to deep space travel stresses. Scientists are using pre- and post-flight X-ray imaging to analyze seed tissue changes and assess implications for long-duration human missions.
This initiative, building on the legacy of the Apollo 14 mission's 'Moon Trees', includes five tree species. Monitoring continues to ensure no abnormalities arise in growth compared to Earth counterparts, providing insight into plant adaptation in extreme environments.
