Africa’s Space Farming Era Begins as South Africa Prepares to Send World-Famous Rooibos Tea to the International Space Station
Africa is taking another remarkable step into the future of science and innovation as South Africa prepares to send its world-renowned rooibos tea plant into space. The ambitious mission will make rooibos the second indigenous African crop to travel to the International Space Station (ISS), highlighting the continent’s growing contribution to global space research while showcasing one of Africa’s most valuable agricultural treasures.
The groundbreaking initiative, known as “Rooibos in Space,” is a collaboration between the South African Rooibos Council and space education company MaxIQ Space, with support from the South African National Space Agency (SANSA). Scheduled for launch in October, the project is expected to place South Africa at the forefront of agricultural space research while inspiring a new generation of African scientists.
A Historic Journey from the Cederberg Mountains to Space
For generations, rooibos has been cultivated exclusively in the Cederberg region of South Africa’s Western Cape, where the unique climate and soil conditions have made the plant an internationally celebrated product. Now, the same seeds that have become synonymous with premium herbal tea will embark on an extraordinary journey beyond Earth.
Once aboard the International Space Station, the rooibos seeds will spend several weeks inside a specialised nanolab, where they will be exposed to the effects of microgravity and cosmic radiation. After returning to Earth, scientists will compare the space-exposed seeds with identical seeds kept under normal conditions on Earth.
Researchers will closely monitor their germination rates, growth patterns, resilience, yield and overall development. The findings could provide valuable insights into how plants adapt to extreme environments and contribute to future agricultural innovations.
Inspiring Africa’s Next Generation of Scientists
Beyond scientific discovery, the Rooibos in Space project places education at its heart.
Students from seven schools across the Cederberg region, the heartland of South Africa’s rooibos industry, will actively participate in the experiment. Working alongside local rooibos farmers and researchers, learners will help collect data, analyse results and gain first-hand experience in scientific research.
Parklands College in Cape Town will conduct a parallel experiment, while schools throughout South Africa have also been invited to participate by designing the official mission patch, encouraging nationwide interest in science, technology, engineering and mathematics (STEM).
According to South African Rooibos Council Director Dawie de Villiers, the project represents a unique opportunity to connect the country’s agricultural heritage with cutting-edge scientific research.
He noted that rooibos has long been an important part of South Africa’s identity and economy, and that sending it into space demonstrates how agriculture, education and scientific innovation can work together to prepare young Africans for future careers in research and technology.

MaxIQ Space founder Judi Sandrock also emphasised that the initiative will give learners practical exposure to scientific investigation, data collection and analytical thinking, helping develop skills that will be essential for tomorrow’s innovators.
Rooibos Continues to Strengthen South Africa’s Global Reputation
The mission also reflects the growing international importance of rooibos as one of Africa’s leading agricultural exports.
South Africa exported approximately 10,930 tonnes of rooibos to more than 50 countries in 2025, surpassing the 10,000-tonne export milestone for the first time. The industry currently produces around 20,000 tonnes annually, with roughly half consumed locally and the remainder exported worldwide.
Beyond its economic value, the rooibos industry supports thousands of jobs across farming, processing, packaging, manufacturing and retail, making it a vital contributor to South Africa’s rural economy.
The product has also achieved international recognition after becoming the first African food to receive Protected Designation of Origin (PDO) status from the European Union. This prestigious certification ensures that only rooibos grown within its recognised South African production region can legally bear the famous name.
Sending rooibos into space therefore serves not only as a scientific experiment but also as a powerful symbol of African excellence, innovation and global competitiveness.
Following Nigeria’s Historic Achievement
South Africa’s mission follows another major African milestone achieved by Nigeria in 2025.
On August 1, 2025, egusi melon seeds sourced from Oyo State became the first indigenous African crop to travel to the International Space Station during NASA’s SpaceX Crew-11 mission. The experiment was led by Nigerian space scientist Dr. Temidayo Oniosun and involved heritage seeds from several countries.
The successful mission demonstrated Africa’s growing role in international space research and opened new opportunities for studying how indigenous crops respond to space environments.
Preparing Agriculture for Life Beyond Earth
Scientists around the world have long studied plant growth in space as humanity prepares for future missions to the Moon and Mars.
Experiments aboard the ISS have successfully grown crops such as lettuce, kale, Chinese cabbage and mustard using NASA’s Vegetable Production System, commonly known as “Veggie.” Researchers continue investigating how plants absorb nutrients, water and light in microgravity to help sustain astronauts during extended space missions.
Other international studies involving crops such as sorghum and Arabidopsis have explored how exposure to cosmic radiation and microgravity may reveal genetic traits capable of improving crop resilience against climate change, drought and extreme temperatures.
These discoveries could ultimately transform agriculture not only for future space exploration but also for farmers facing increasingly challenging environmental conditions on Earth.
Africa’s Growing Presence in Space Science
The Rooibos in Space initiative represents far more than a scientific experiment. It reflects Africa’s growing ambition to become an active contributor to global research, innovation and technological advancement.
By taking one of its most iconic agricultural products beyond Earth’s atmosphere, South Africa is demonstrating that African science, agriculture and education can play a meaningful role in addressing global challenges while inspiring future generations.
Together, the Nigerian egusi mission and South Africa’s rooibos project mark the beginning of a new chapter in Africa’s participation in space science—one where indigenous crops, local knowledge and scientific excellence converge to shape the future of agriculture both on Earth and beyond.
