Join the New Zealand Astrobiology Network to learn how seeds grow in space on the International Space Station.

Grow plants

like an astronaut

Join us in an out-of-this-world experiment as we explore the effect of microgravity on plants. This is your chance to grow seeds in concert with astronauts aboard the International Space Station!

in 2021




In 2021, astronauts aboard the International Space Station are undertaking a plant-growth experiment with basil seeds. 

The Japanese Space Agency (JAXA) has sent us some seeds from the exact same batch as those being flown into space, to give you a chance to perform your own experiments here on Earth. 

Grow your own ‘space seeds’ and compare the differences. 

How do seeds grow in space?

How does gravity affect seeds grown on Earth?

Follow along as the astronauts tend to the seeds on the ISS – and spot the differences and similarities with your own seeds’ growth. 


Send us your results by 20th of September 5PM and win a portable planetarium visit

The results from the ISS will return to Earth in July and will be analysed in Japan.
Following requests from teachers who wanted to compare the results on Earth with the results from the ISS
we decided to extend the date for submitting your posters and results. 

You have 

to finish your project.

Your results will be judged by the NZAN board.
