NASA's Space-Exposed Tomato Seeds Show No Significant Long-Term Changes After Six Years in Orbit
In 1984, NASA initiated a unique experiment called Space Exposed Experiment Developed for Students (SEEDS) by sending approximately 1.25 million tomato seeds into space. These seeds remained in orbit for six years, returning to Earth in 1990. The primary objective was to determine if prolonged exposure to the space environment would alter the germination and growth patterns of plants. Upon their return, NASA distributed these space-traveled seeds, along with a control group of Earth-bound seeds of the same 'Rutgers California Supreme' variety, to approximately 3.3 million students across 40,000 schools in all 50 U.S. states and 30 other countries. Students were tasked with planting both sets of seeds and meticulously recording observations on germination rates, sprout emergence time, and plant development, including stem length, leaf formation, and fruit production. The collected data, comprising around 8,000 reports, was then sent back to NASA for scientific analysis.
