Plants On Planets?

This made us want to find out more about plants in space. Through deeper research, the answer "Mars" in question 8 was not quite right. So far, experiments have only been done on Martian soil. It was found that Martian soil contains few nutrients, and is also high in lime and salt, but that there are some plants for which this nutrient content is sufficient to grow: "They found that alfalfa grows just as healthy as it does on Earth without additional fertilizer."

– Researchers said in David Nield's article, This Is The First Plant We Should Grow on Mars, New Study Finds in: Space. August 2022 In: https://www.sciencealert.com/thisis-the-first-plant-we-should-grow-on-mars-new-study-finds ; accessed 04 Jan. 2023)

Since Mars is a cold, dry, and inhospitable planet that lacks the conditions necessary for life as we know it, plants fare poorly. Nevertheless, Nasa is doing research in this area. Because on Aug. 10, 2015, romaine lettuce was on the "lunch plate" of Expedition 44 crew members on the ISS - the international space station - for the first time. (Abb. 08) The special thing about it was that the lettuce was grown on the ISS itself. The first cushion was activated in May 2014, watered and has since been nurtured in an artificially created environment.
