Education Payload Operations-Tomatosphere II (EPO-Tomatosphere II) - 05.13.15
Education Payload Operations-Tomatosphere II (EPO-Tomatosphere II) includes curriculum-based educational activities that demonstrate basic principles of science, space, and agriculture. These activities are videotaped and then used in classroom lectures. EPO-Tomatosphere II is designed to support the NASA mission to inspire the next generation of explorers.

The objective of Education Payload Operations-Tomatosphere II (EPO-Tomatosphere II) investigation is to expose a group of tomato seeds to the microgravity environment of the International Space Station (ISS) in order to to create educational video and multimedia products that inspire the next generation of mathematicians, physicists, engineers, and other scientists.
The products are used for demonstrations and to support curriculum materials that are distributed across the United States and internationally to educators.
Students experiment with seeds exposed to 18 months on ISS and control seeds that remained on Earth.
Education Payload Operations-Tomatosphere II (EPO-Tomatosphere II) uses the excitement of space exploration as a medium for teaching students about science, space, and agriculture. EPO-Tomatosphere II allows students to experiment with 1.5 million tomato seeds exposed to 18 months on the International Space Station (ISS) and control seeds that remained on Earth. The seeds are distributed to classrooms throughout Canada, the United States, and several other countries. Students measure the germination rates, growth patterns, and vigor of growth of the seeds.
EPO-Tomatosphere II introduces the next generation of explorers to the environment of space.
EPO-Tomatosphere II is part of NASA's continuing effort to use space as a unique educational tool for K-12 students.
The 1.5 million Tomatosphere-II seeds from Expedition 9 were divided and distributed to 160,000 students in 6,000 classrooms across Canada. (Evans et al. 2009)^ back to top
