Ok, bad pun! But growing produce on Mars is quite a work in progress, by the folks at MarsOne. Tomatoes, especially.
Despite the Matt Damon agro project, growing food is not going to be easy, from accounts I have read. I know of a teacher who is germinating plants on moon-like soil.
In this blog post by Natasha Schön, she talks about biomass measurements, and the first tomato that grew in martian-simulated soil. Schön explain the need for more work on this:
One of the follow up experiments will be to investigate if the produced seeds are viable. It would only make sense to cultivate crops on Mars or the Moon if the follow up experiments are a success and the seeds are able to form new plants. If the seeds are not viable, a constant stream of new seeds would have to be flown in, making Mars farmers highly dependent on seed deliveries from Earth.
And yes, they also tried growing peas.
And to justify the bad pun (in the title of this post), there is a children’s book titled “Peas on Earth.”
I believe it has a sustainability angle!
