Astronauts on ISS Eat Veggies They Grew in Space

Astronauts Scott Kelly, Kjell Lindgren and Kimiya Yui of Japan sample the fruits of their labor after harvesting a crop of “Outredgeous” red romaine lettuce from the Veggie plant growth system on the International Space Station.

Before consumption the leafy greens are cleaned with citric acid-based, food safe sanitizing wipes. Half of the crop will be consumed while the other half will be packaged and frozen until it can be returned to Earth for scientific analysis. Check out the embedded video below for the first official tasting! [source]

 

 

NASA is maturing Veggie technology aboard the space station to provide future pioneers with a sustainable food supplement – a critical part of NASA’s Journey to Mars. As NASA moves toward long-duration exploration missions farther into the solar system, Veggie will be a resource for crew food growth and consumption. It also could be used by astronauts for recreational gardening activities during deep space missions.

The first pillows were activated, watered and cared for by Expedition 39 flight engineer Steve Swanson in May 2014. After 33 days of growth, the plants were harvested and returned to Earth in October 2014. At NASA’s Kennedy Space Center in Florida, the plants underwent food safety analysis. The second Veg-01 plant pillows were activated by Kelly on July 8 and grew again for 33 days before being harvested. The seeds had been on the station for 15 months before being activated.

If we plan on exploring great distances in space, growing our own food will be integral.

The collapsible and expandable Veggie unit features a flat panel light bank that includes red, blue and green LEDs for plant growth and crew observation. Using LED lights to grow plants was an idea that originated with NASA as far back as the late 1990s.

The purple/pinkish hue surrounding the plants in Veggie is the result of a combination of the red and blue lights, which by design emit more light than the green LEDs. Green LEDS were added so the plants look like edible food rather than weird purple plants. [source]
