ISS Update #2: Getting Ready to Dine on Lettuce...
Testing Hardware for Growing Plants and Vegetables in Space (Press Release)
Astronauts on the International Space Station continue testing the VEGGIE hardware for growing vegetables and plants in space. VEGGIE provides lighting and nutrient supply for plants in the form of a low-cost growth chamber and planting "pillows" -- helping provide nutrients for the root system. It supports a variety of plant species that can be cultivated for educational outreach, fresh food and even recreation for crew members on long-duration missions.
Further work on the VEGGIE hardware validation test (VEG-01) began on Monday, July 20, 2015 when NASA astronaut Scott Kelly photographed the progress of the plants thus far and watered them the next day. On Friday, July 24, new crew member and NASA astronaut Kjell Lindgren took over watering duties and photographic documentation of the plants. Knowledge from this investigation could benefit agricultural practices on Earth by designing systems that use valuable resources, such as water, more efficiently.
