UNL team will fly with NASA Microgravity University in July

            This year, a team of University of Nebraska-Lincoln engineering students will pilot a free-flying vehicle--like the radio-controlled helicopters popular as holiday gifts--not to escape their courses, but to help NASA research.

            Selected university teams will perform experiments on reduced gravity missions flying from NASA's Johnson Space Center in Houston, July 26-Aug. 3, during the 2013 NASA SEED Microgravity University.

            It's the sixth consecutive year that UNL has been selected for the program. NASA Microgravity University conducts scientific research that helps the U.S. space program advance its efforts. Projects are prepared by students with mentoring from NASA and industry representatives, then conducted during "Flight Week" aboard a series of parabolic flights in specially-equipped aircraft that reach 35,000 feet in altitude.

            UNL's 2013 assigned project, ARGOS and Microgravity Free Flyer Evaluation, will explore the ability of the Active Response Gravity Offload System to provide a microgravity environment for a free-flying vehicle.

            ARGOS is a robotic system that provides reduced gravity environments through a large motion-based platform at JSC that has been used for human and robotic testing over the past three years, said JSC's ARGOS lead representative, Larry K. Dungan. ARGOS has not been used for testing free flyers and the evaluation of the ARGOS control system to maintain a microgravity environment for a free flyer is a unique area of research.

            According to UNL's confirmation letter from NASA, the Nebraska team will need to develop a free flyer (likely a quad or hexa-copter) that will fly a specific set of motion patterns in both ARGOS and plane- induced microgravity environments.

            The UNL team is also tasked with devising a data collection method for comparing performance in the environments, via motion capture camera systems and inertial guidance units. This data will help refine ARGOS and its control systems in further study of free flyer performance in reduced gravity settings.

            The 2013 UNL microgravity team's student captain, Jake Reher, said the team is "extremely excited to get started on our research project which we will fly in July." Reher, a senior mechanical and materials engineering major from Omaha, said the UNL team has been growing in numbers each year, particularly with underclassmen. He added that the team is eager to promote interest in research and discovery within the community and among aspiring engineers as the students work with NASA and the JSC ARGOS Lab group in coming months.

            The team's advisers are Carl Nelson, associate professor of mechanical and materials engineering, and Dustin Dam, a 2008 UNL electrical engineering graduate and captain of UNL's 2008 microgravity team.
