Gemm, Nova, and Jarrell are traveling to a space station orbiting Jupiter. On their two-year journey, they experiment with the oxygen levels given off by saplings in microgravity environments. Will they be able to prove that saplings give off more oxygen in space, and can they get their results back to the scientists on Earth?
