Prof Nabity's research enables robust long-term and far-reaching human space flight systems. His research includes environmental control and life support systems (ECLSS), spacecraft and habitat design, and in situ resource utilization. Doctoral students engage in the following research activities: 1) ionic liquids for atmosphere revitalization, gas separation and solvated extraction of minerals and oxygen, 2) crew exposure to space radiation, 3) model the influence of space radiation on crew performance, 4) robust ECLSS, 5) spacecraft and spacesuit thermal control, and 6) plant growth chambers. Funded projects researched a novel freezable spacecraft radiator, capillary-driven water/nutrient delivery, and a supported liquid membrane for CO2 sequestration from the Mars atmosphere. Articles describe the characterization of ionic liquids for CO2 capture or removal, ECLSS failure modes and fault propagation, multilayer insulation for deployable structures, and robust ECLSS.

ASEN 4013 - Foundations of Propulsion
Fall 2018 / Fall 2019 / Spring 2020 / Fall 2020
Describes aerothermodynamics and design of both rocket and air-breathing engines. Includes ramjets, turbojets, turbofans, and turboprop engines, as well as liquid, solid, and hybrid rockets.
ASEN 6028 - Graduate Projects II
Spring 2018 / Spring 2020 / Fall 2020 / Spring 2021
Exposes MS and PhD students to leadership positions in project management and systems engineering while working a complex aerospace engineering project as part of a project team. The project team may perform some or all of the following project activities during this second semester of the two-semester course sequence: requirements definition, design and design review, build, test, and verification. Recommended prerequisite: ASEN 4138 or ASEN 5148 or ASEN 5018 or ASEN 5158 or instructor consent required.
ASEN 6116 - Spacecraft Life Support Systems
Spring 2019 / Spring 2021
Study the environmental control and the life support systems and technologies that keep people alive and healthy in spacecraft and habitats. Students will learn about thermal control systems, air revitalization processes, water reclamation and treatment, waste handling and the reuse of materials, and food and nutrition. Expect to develop analytical models from first principles and perform hands-on laboratory experiments. Formerly ASEN 5116.
