Graduate student Heather Hava鈥檚 gardening skills are out of this world.
Hava, who is in , has dedicated much of her 抖阴旅行射 Boulder academic life to developing advanced fruit and vegetable gardening systems that may someday be used by spacefarers living in outposts on Mars or the moon. Think movie astronaut Mark Watney, who actor Matt Damon played in The Martian.
In October, Hava was a speaker at a panel discussion on long-term space exploration at Pittsburg鈥檚 Carnegie Mellon University as part of the inaugural White House Frontiers Conference focused on advancing U.S. science, technology and innovation.
鈥淭he natural evolution of a society is to go out and explore,鈥� says Hava. 鈥淎nd at some point we will move off the Earth and out into the solar system. Space gardening is one of the first steps to getting there.鈥�
In September, Hava and former 抖阴旅行射 Boulder student Daniel Zukowski were one of six graduate student team finalists in the 2016 national Collegiate Inventors Competition. The pair was nominated for developing a plant growth chamber and accompanying software that could be used by astronauts for space gardening.
Smart gardening
Hava is a pioneer in her field. She has designed and built a device called SmartPot听(SPOT), which is a compact hydroponic chamber for growing plants in space. Nutrient-rich water circulates through the chamber, which is autonomously controlled for temperature, humidity, light and ventilation and can be operated by either astronauts in space or remotely by NASA鈥檚 mission control on Earth.
Hava and her team also developed an accompanying software package, called AgQ, to process SPOT data using a variety of sensors placed inside the chamber.
In addition, she led the development of the Remotely Operated Gardening Rover (ROGR), which has the ability to buzz around in a space habitat, perhaps on Mars, to check on and even harvest space gardens. ROGR was part of NASA鈥檚 X-Hab Innovation Challenge, which annually awards monetary prizes to student research teams at a handful of universities to advance technology for deep-space missions.
So it is听really no surprise to those in the know that Hava won the $15,000 鈥淓at it!鈥� Lemelson-MIT graduate student prize last spring, making her the top graduate student inventor for technology-based advances that can improve food and agriculture.
鈥淓ating is the one of most fundamental, basic things we do as humans,鈥� she explains. 鈥淪o part of what I do is develop robots that can garden in space.鈥�
Gardening is a morale booster for astronauts living in a 鈥渕achine environment,鈥� she explains. Using plants to improve astronaut psychological health and cognitive performance is a major aspect of her research.
Her advisor听Assistant Professor Nikolaus Correll of 听said Hava is a driven person who has racked up a number research awards in recent years. 鈥淚 know she would like to be selected to be an astronaut someday,鈥� Correll says. 鈥淔rankly, I鈥檓 not surprised at anything Heather does once she puts her mind to it.鈥�
But Hava still has an 鈥淓arth鈥� side to her. She invented and patented a geodesic dome structure that could be used for horticulture, sustainable housing and disaster relief around the globe. Hava also completed Master Gardener training in 鈥減ermaculture,鈥� a system of agricultural and social design principles that uses patterns and features observed in natural ecosystems.
Commercial innovation
Hava is working on commercializing her inventions through her two Colorado-based startup companies: Autoponics, of Longmont, to develop food production for space habitats听and Stellar Synergetics LLC, of Golden, specializing in geodesic dome structures and design.
鈥淭hese technologies not only can solve long-term human space exploration challenges,鈥� she explains. 鈥淚n the near-term they also have the ability to help our planet meet the growing challenges of feeding 9 billion people.鈥�
Hava鈥檚 academic emphasis is bioastronautics, which encompasses biological, behavioral and medical aspects of humans and other living organisms in a spaceflight environment. The program includes the design of payloads, spacecraft habitats and life-support systems.
In order to keep her research moving forward, Hava said she is continually seeking funding for both her research and companies.
A recipient of a four-year NASA Space Technology Research Fellowship in 2012, Hava has serious aspirations to become a NASA or commercial astronaut.
鈥淚 could potentially see myself as one of the first space gardeners on Mars,鈥� she says. 鈥淗ow can it get any better than floating in space and eating a fresh strawberry?鈥�
