Research at the University of Hawai?i at Manoa could play a major role in NASA's goal to travel to Mars in the 2030s, including what the astronauts could eat during that historic mission.
A trip to Mars and back is estimated to take about two and half years, and ideally, their diet would be healthy while requiring minimal effort and energy. UH Manoa mechanical engineering student Aleca Borsuk may have the solution.
"I picked a really hearty, heat tolerant, drought tolerant species of edible vegetable, and that is amaranth. It's an ancient grain," said Borsuk, who determined that she could significantly increase the edible parts, which is basically the entire plant, by changing the lighting. "If you move the lights and have some of them overhead and some of them within the plant leaves, it can actually stimulate them to grow faster and larger."
This is without adding more lights and by using energy efficient LEDs. Thanks to Borsuk's work with lighting, plants could play an important role in the future of space travel.
"This plant would do the same thing that it does here on Earth, which is regenerate oxygen in the atmosphere," said Borsuk. "It also can provide nutrition for the astronauts and if you can imagine being away from Earth for many years, you know tending something that's green would have a psychological boost as well."
A 2013 UH Presidential Scholar, Borsuk presented her research at the Hawai?i Space Grant Consortium Spring 2016 Fellowship and Traineeship Symposium and at the 2016 American Society for Horticultural Science Conference in Florida. She is mentored by UH Manoa Tropical Plant and Soil Sciences Associate Professor Kent Kobayashi, who is also an American Society for Horticultural Science Fellow.

After spending nearly a month tending to the International Space Station's first crop of Chinese cabbage, astronaut Peggy Whitson harvested the leafy greens on Feb. 17. At first, one of the six seeds of the Tokyo Bekana Chinese cabbage variety seemed to have been planted higher than the rest, keeping it from getting wet enough in the beginning. But the on-orbit gardener would not be deterred. ... read more
