Agnirva Space Premier League - Expedition #32543: Growing Tomatoes in Space: The Tomatosphere 8 Experiment

What happens when you grow tomato seeds that have traveled to space? That’s the question behind Tomatosphere 8, a project designed to engage students in real-world science using space agriculture. Spearheaded by Janice Cudlip from the Canadian Space Agency and involving partners like Let’s Talk Science, HeinzSeeds, and Stokes Seeds, this experiment reached schools across North America through Expeditions 70 and 71 aboard the International Space Station (ISS).

Here’s how it works: seeds are divided into two groups—one sent to space, the other kept on Earth. After their return, both sets are distributed to classrooms. Students plant and monitor them, then compare growth results. The twist? They don’t know which seeds went to space until after their data is collected. This blind test makes it a true scientific investigation.

Students become scientists as they consider factors like germination rates, growth patterns, and environmental effects. By doing this, they learn not only about biology and agriculture, but also about the effects of space conditions like microgravity and radiation on living organisms.

Why tomatoes? Tomatoes are an important crop, rich in nutrients and a potential candidate for sustaining astronauts on long missions. Understanding how seeds react to space can help us prepare for farming on Mars or the Moon.

This engaging and educational experiment demonstrates the power of inquiry-based learning. Students aren’t just learning about space—they’re contributing to it.
