Thomas Pesquet holds bags filled with 1.2 million tomato seeds for the Tomatosphere project run by the Canadian Space Agency. Students in 20,000 classrooms across Canada and the U.S. will receive the seeds when they return to Earth. The students will grow the tomato plants and compare them to tomato plants grown from seeds that didn't fly to space.
