The project is also an opportunity to raise international awareness of rooibos. Making history through space research could attract global attention and give the Rooibos Council a platform to share the story of this uniquely South African product with the world.

South African Rooibos Council research director Joe Swart said the experiment will also involve schoolchildren. Researchers hope the findings could provide new insights for the local rooibos industry.

He said the uncertainty surrounding the results is part of what makes the project exciting. “We don’t really know what to expect. When the seeds return, schoolchildren will plant them alongside ordinary rooibos seeds and compare how they germinate and grow.

If the experiment shows that space conditions affect the germination, growth, or development of rooibos, the findings could have significant benefits for future research and the South African rooibos industry.

The research could eventually help develop rooibos plants that grow faster, produce better yields and become more tolerant of drought and other environmental stresses. These developments could bring considerable benefits to farmers.

“It is still too early to know what the experiment may reveal. The seeds may also not show any changes at all.” Despite the uncertainty, the project is already generating international publicity for rooibos. Increased demand could create opportunities for better prices for farmers, support job creation and boost exports.

The project brings together scientists, farmers, schools, the South African National Space Agency and MaxIQ in an international research collaboration.

For Swart, one of the most exciting aspects is the opportunity for schoolchildren to conduct real research using seeds that have travelled to space and been exposed to microgravity and radiation. Through the project, learners will gain practical experience in mathematics, science, and agriculture.

“I believe the initiative also creates opportunities to promote healthier lifestyles, support the agricultural economy, and introduce the world to the Cederberg, the home of rooibos.”
