Learners from Cederberg schools and Parklands College will compare space-travelled Rooibos seeds with anEarth-based control group to study germination and growth. Rooibos tea is heading into orbit as part of a South African experiment combining space science, agriculture and school-based STEM education. The Rooibos in Space programme was launched last month at the Parklands College Innovation Centre in Cape Town. In October, a batch of Rooibos seeds is due to travel to the International Space Station, where it will be exposed to microgravity and space radiation for several weeks. The programme was conceived by the South African Rooibos Council and is being delivered with MaxIQ Space, with support from the South African National Space Agency.
