Microgreen Growth Experiment: SpeCES experiment starter with 2 black trays inside the cabinet and 2 outside. The whole setup is no the Greenhab.
Space Nutrition Task: Part 1 Nutrines Catalog is well underway. We only have 2h of Internet a day (also for personal use not only mission related uses) so it is very challenging to work on it when you need to tap into the Internet for values. We will make progress but the mission profile is what it is 🙂
