NASA astronaut Jessica Meir introduced two new plants—red Russian kale and wasabi mustard—being grown aboard the International Space Station as part of Expedition 75.
The crew is tending to these plants in their spare time to research how flora grows in the open cabin environment rather than specialized habitats, as well as to test how space stowage impacts seed viability, while also benefiting from the mental wellness and "nature therapy" of having living green plants in space.
