It’s Sunday morning, and Ryan is still asleep, and I got a bit bored and started playing around with one of those “blog title generators”. (For those of you for whom this is a new concept, they generate click-bait style headlines for a topic you give them.)

Hello, and welcome to episode 30 of Gardeners of the Galaxy, the podcast for all of the sentient beings in the Universe who have a passion for plants. I’m Emma the Space Gardener, and I will be your host as we explore gardening on Earth… and beyond!
When we look forward to long-duration space missions, one of the concerns is that the nutrients in food degrade during storage. With our current food technologies, it’s hard to pre-pack food that will nourish astronauts during the return journey from Mars, for example.
One solution is for the crew to grow some fresh food, and researchers all over the world are investigating different ways to do that, and we’ve heard from quite a few of them over the last year.
Here on Earth, over the last few years, there has been a trend towards growing microgreens. Microgreens are essentially seedlings, packing a large amount of nutrition into a small amount of plant matter. They’re quick and easy to grow and harvest, don’t take up much space and can really pack a punch in the flavour department.
For all of those reasons, microgreens sound like they would be ideal crops for astronauts. But as yet, we haven’t seen any astronauts giving them a

Microgreens in Space
During Lockdown I have done some sprouting – growing corn shoots, beansprouts, wheatgrass and pea shoots on the windowsill to use as salad and stir fry ingredients. We didn’t really rate the corn shoots and wheatgrass (and the leftover seeds are destined to go through the mill!), but the beansprouts and pea shoots are old favourites we sprout from time to time. The benefits of sprouts are that you get a large amount of nutrition from a small space, in a small amount of time.
