Inside a laboratory in the Space Station Processing Facility at NASA’s Kennedy Space Center in Florida, research scientists prepare the plant pillows for the Veg-03 experiment that will be delivered to the International Space Station aboard the eighth SpaceX Dragon commercial resupply mission. From left, are Matt Romeyn, NASA pathways intern; Dr. Gioia Massa, NASA payload scientist for Veggie; and Dr. Mathew Mickens, a post-doctoral researcher. The Veg-03 plant pillows will contain ‘Tokyo Bekana’ cabbage seeds and lettuce seeds for NASA’s third Veggie plant growth system experiment. The experiment will continue NASA’s deep space plant growth research to benefit the Earth and the agency’s journey to Mars.
