Sending T-Cells Into Space EMBRY-RIDDLE PAYLOAD TO ASSESS MICROGRAVITY IMPACTS ON THE IMMUNE SYSTEM

GETTING IT OFF THE GROUND The payload itself will be housed in a 3-D printed struc- ture designed and printed at Embry-Riddle’s Engineering Physics Propulsion Lab on the Daytona Beach Campus in Florida. It was tested to meet the different milestones set by Blue Origin’s payload users guide for ensuring the safety and containment of biological agents. To plan the mission, Llanos formed three teams to work on the suborbital payload: a flight operations team, a design and engineering team, and a science team. “We went through various design iteration processes and worked closely to test the designs using computa- tional analysis software,” says Vijay Duraisamy, a mechan- ical engineering Ph.D. student who worked on the project along with a large team of Llanos’ undergraduate students. COLLABORATION IS KEY Because of the nature of this multidisciplinary project, students had to build and expand their team dynamics by working with other teams at the university, as well as with industry experts. Llanos says the project, which was awarded second place at the 2017 Embry-Riddle Discovery Day Awards, allowed the team to work on real-world opportunities while giving students the chance to collaborate with other groups and mature their problem-solving skills. A second payload, which will measure conditions aboard Blue Origin’s New Shepard rocket before the spacecraft’s first manned flight, is in the works. / TOM IACUZIO

W hen Blue Origin’s New Shepard vehicle makes its next launch into space from West Texas, it will have a little bit of Embry-Riddle Aeronautical University on board: a payload designed by students in Pedro Llanos’ Satellite and Spacecraft Systems class. The Cell Research Experiment in Microgravity (CRExIM) suborbital payload will be the first of what he hopes will be many payloads to fly through Embry-Riddle.

“It’s a multidisciplinary effort between various col- leges at Embry-Riddle and other universities nationwide,” Llanos says. “Spaceflight operations and aerospace/ mechanical engineering students — along with Embry- Riddle’s Department of Applied Aviation Sciences — are working together with a science team comprised of the University of Texas Health Science Center at San Antonio and the Medical University of South Carolina.” THE MISSION The CRExIM payload, which contains T-cells iso- lated from mice and grown in the laboratory, will be exposed to microgravity for about three and a half minutes. These types of cells are the main warriors of our immune system, tracking down and defeating cells that are infected or have become cancerous. The idea behind the experiment is to get insights on how brief exposure to micrograv- ity orchestrates the landscape of different types of immune cells, say Llanos and his colleague Kristina Andrijauskaite with the University of Texas Health Science Center. Sathya Gangadharan, a mechanical engineer- ing professor who helped advise on the design of the structure of the payload, says: “I’m very glad that Embry-Riddle is pioneering this new area of cancer cell research from a biomedical engineer- ing perspective, utilizing its past experiences in microgravity to bring solutions to problems that are critical to the medical field.”
