Analysis of Seed Sanitization, Rapid Freezer Proficiency, and Veg-03 Water Verification

In order to ensure the well-being of astronauts and experiments on the ISS (International Space Station), seeds need to be free of microbes, the rapid freezer needs to be freezing biological samples evenly and proficiently, and the astronauts need to have accurate watering procedures for Veg-03 (the latest Phytotron for the Veggie (Vegetable Production System) project). Seed flight candidates were sanitized with varying levels of HCL in order to determine the right amount to use for future flight experiments, too much HCL and the seeds will not germinate and too little and they will be contaminated with microorganisms. The rapid freezer was assessed using temperature probes to determine if there is a homogeneous change in temperature in order to ensure the safe freezing of biological organisms. The plant watering procedures given to the astronauts were assessed in order to make sure that Veg-03 experiments are receiving the correct amount of water.
