Agnirva Space Premier League - Expedition #31553: Exploring Fungus Mycelium Growth: A Comparative Study in Space and on Earth

Have you ever wondered how living organisms adapt to the extreme conditions of outer space? One fascinating experiment conducted by the Espoo Christian School, in collaboration with the Lowell Center for Space Science and Technology, delves into this very question. Their research, carried out aboard the International Space Station (ISS) during Expeditions 39/40, aimed to compare the growth of fungus mycelium in microgravity to that on Earth.

Fungus mycelium—essentially the root-like structure of fungi—is known for its ability to grow through various mediums, playing a vital role in ecosystems as decomposers. The goal of this experiment was to observe how the lack of gravity affects mycelium development and structure. In microgravity, where sedimentation and convection don’t occur as on Earth, scientists predicted that the growth pattern and morphology of mycelium might exhibit unique characteristics.

Students and researchers monitored fungal samples in both space and classroom-based Earth controls. They used cameras, growth media, and data logs to analyze the behavior of the fungus. Key metrics included growth speed, branching patterns, and density.

The space-based fungi were subjected to real-time observations and post-flight analysis. Results from this project can inform future biotechnological applications in space, such as biodegradable materials or biological life support systems. Moreover, this educational project empowered students to engage in authentic scientific inquiry, sparking curiosity and developing skills in hypothesis formation, data collection, and analysis.

By conducting this side-by-side investigation in two vastly different environments, the project illustrated the tangible effects of gravity—or the lack thereof—on biological processes. This experiment served as an excellent model of how education, science, and space exploration can intersect to inspire the next generation of scientists.
