University of Colorado Boulder students and faculty have been selected to develop a remotely operable, robotic garden to support future astronauts in deep space. The project is one of five university proposals selected to participate in the 2013 Exploration Habitat (X-Hab) Academic Innovation Challenge led by NASA and the National Space Grant Foundation.

The yearlong project will be funded by a grant of about $40,000. Its ultimate goal is to support long-duration human space exploration, such as a mission to Mars, according to Christine Fanchiang, a graduate student in aerospace engineering sciences who is one of three core students managing early project development.

The project will be led by CU-Boulder Professor Joe Tanner, a former astronaut now teaching in the aerospace engineering sciences department, Nikolaus Correll, a computer science professor who previously spent two years working on robotic gardening systems at MIT, and Dave Klaus, an aerospace engineering professor with expertise in space habitat design and space life sciences.

Adriane Elliott of Colorado State University's department of soil and crop sciences also will collaborate on the project.

Students from two graduate-level aerospace engineering courses at CU-Boulder will focus on the project next year in order to deliver an operating system to NASA in the summer of 2013.

The completed project will be a bioregenerative food system that will grow, harvest and compost a variety of plants. Bioregenerative systems support life by simultaneously revitalizing the atmosphere, purifying water and producing food for consumption.

The team already has a prototype growing environment for autonomous plant production that is based on work done in CU-Boulder's computer science department over the last two years.

The system will be further developed to perform four major tasks: seeding, monitoring of plant growth, harvesting, and processing of crop residue to recycle nutrients back into the system.

A strategy for implementing the automation to achieve time savings for the astronauts while maintaining some of the beneficial psychological aspects of gardening also will need to be developed, Fanchiang said.

"Psychology is a major driver of how well people can survive in isolated, confined environments," she said. "Picking the tasks to automate and determining if there is a way to mix automation with some manual tasks, like picking the fruit, are part of the project."

Fanchiang is excited about the multidisciplinary nature of the gardening project, and of the bioastronautics field in general. "It's fun because you get to see something outside of your own expertise," she said.

In addition to advancing the goal of sustaining a mission to Mars, Fanchiang noted that the food production project also could be useful for people in everyday life.

Throughout the 2012-13 academic year, the Colorado team will need to meet a series of milestones to design, manufacture, assemble and test their systems and concepts in cooperation with the NASA Advanced Exploration Systems (AES) Program's Habitation Systems Project team.

"The X-Hab Academic Innovation Challenge is an exciting opportunity to engage university teams in the design process for NASA's next-generation space systems," said Jason Crusan, NASA's AES Program manager at NASA Headquarters in Washington, D.C. "The agency benefits from the fresh and innovative perspective of these university teams, and they learn about deep space human exploration and the systems engineering approach from an experienced NASA team."

Volunteers Sought for Simulated Mars Mission and Study of 'Menu Fatigue'
Ithica NY (SPX) Jan 27, 2012
Astronauts on a mission to Mars will need much more than freeze-dried ice cream to sustain them, and researchers at Cornell are working to determine the best way to keep them well nourished during their three-year journeys and four-month stays on the Red Planet. To do so, they are seeking volunteers to spend four months in a simulated Mars habitat on the barren lava fields of Hawai'i. ... read more
