An experiment that’s on its way to the International Space Station focuses on a subject that’s as common as dirt, but could be the key to growing crops in space.
The NASA-funded experiment — known as Dynamics of Microbiomes in Space, or DynaMoS — is being conducted by researchers at the Pacific Northwest National Laboratory. DynaMoS makes use soil and bacteria that were collected at a Washington State University field site in Prosser, Wash.
“Soil microbes are the hidden players of the life support system on planet Earth,” PNNL chief scientist Janet Jansson, the principal investigator for the DynaMoS experiment, explained during a pre-launch news briefing. The bacteria work to break down organic matter and make nutrients available for growing plants.
Space missions could extend the microbes’ reach beyond our home planet. “Soil microbes can help to make conditions on the lunar surface and Mars more favorable for plant growth,” Jansson said. “They can also be used to help grow crops on space stations and during long-term spaceflight.”
