Admittedly, it’ll be quite some time before the International Space Station is serving up its own homegrown salad bar, but this week, astronauts aboard the ISS are set to grub down on their second and latest round of space grown vegetables – a tasty variety of Chinese cabbage known as Tokyo Bekana.
About a year and a half ago in August 2015, ISS astronauts first got to eat a vegetable in space they’d grown themselves: a tiny bounty of red romaine lettuce. According to Modern Farmer, since then, NASA has worked hard to improve their space farming fortunes. “We conducted a survey of several leafy green vegetables and looked at how the crops grew, how nutritious they were, and how a taste panel felt about them,” said Gioia Massa, a scientist on the project, explaining the quest for the perfect space produce. “The ‘Tokyo Bekana’ Chinese cabbage variety was rated as the top in growth and the favorite of tasters.”
Armed with this new fast growing, delicious tasting (at least by NASA taster standards) vegetable, astronauts began their first foray into zero-gravity cabbage growing. Though things were said to go “generally” well, growing produce in space still isn’t easy. The Tokyo Bekana not only grew “a bit more slowly” than predicted, it also faced a bit of yellowing due to the station’s high CO2 levels.
