Participants, comprising approximately 3.3 million students from diverse educational backgrounds worldwide, received kits that included seeds launched into space and Earth-based controls for comparison. Preliminary findings indicated a marginally enhanced germination rate for the seeds sent to space, though notable growth differences diminished during the plants’ life cycles.
