Veg-04 A On-Orbit

Mizuna Mustard mustard greens, part of the Veg-04A experiment, are shown growing in a Veggie plant growth chamber aboard the International Space Station on July 9, 2019. The Veg-04A experiment tested the greens, grown in blue-rich lighting and red-rich lighting, to determine the effects of different light ratios on plants grown in space on the station. The plants arrived aboard the SpaceX Commercial Resupply Services-16 mission. Astronaut Christina Koch initiated the on-orbit experiment on June 4, 2019, in the station’s two Veggie plant growth chambers, with six plant pillows per chamber. On June 11, 2019, Koch thinned the Mizuna plants to one plant per pillow. The on-orbit harvest took place July 9, 2019, with astronaut Nick Hague harvesting the plants grown under blue-rich light and Koch harvesting the plants grown under red-rich lights.
