Sound like far-fetched sci-fi? Think again.

This cosmic cuisine scenario is fast becoming our reality, thanks to research led by University of Melbourne scientists belonging to the Australian Research Council Centre of Excellence in Plants for Space (P4S, 2024-2030), in partnership with NASA and other space scientists.

A global dream team of over 40 scientists in 11 countries and seven space agencies have united to produce a roadmap for plant science breakthroughs crucial for long-term human life on the moon and Mars.

When Scott Kelly tweeted a picture of moldy leaves on the current crop of zinnia flowers aboard ISS, it could have looked like the science was doomed. It was in fact an opportunity for scientists back on Earth to better understand how plants grow in microgravity, and for astronauts to practice doing what they’ll be tasked: autonomous gardening.

The Veggie plant growth facility was installed on the orbiting laboratory in early May of 2014, and the first crop – ‘Outredgrous’ red romaine lettuce – was activated for growth. The first growth cycle faced some issues...
