The German space agency, DLR, has been experimenting growing tomatoes
in a container full of urine. The experiment is designed to test recycling of waste as a means of growing food for future space colonies.
An experimental satellite containing the package is scheduled to be launched
on a SPACE X FALCON 9 rocket later this year to test the concept.
