Research Centers Supported by the Space Research Initiative

Across Georgia Tech, researchers are exploring the universe — its origins, possible futures, and humanity and Earth’s place in it. These investigations are the efforts of hundreds of astrobiologists, astrophysicists, aerospace engineers, astronomers, and experts in space policy and science fiction — and all of this work is brought together under the Institute’s new Space Research Initiative (SRI).

The SRI is the hub of all things space-related at Georgia Tech. It connects research institutes, labs, facilities, Schools, and Colleges to foster the conversation about space across Georgia and beyond. As a budding Interdisciplinary Research Institute (IRI), the SRI currently encompasses three core centers that contribute distinct interdisciplinary perspectives to space exploration.

Center for Space Technology and Research

The Center for Space Technology and Research (CSTAR) is a hub dedicated to furthering the expansion of Georgia’s aerospace industry, which is already the state’s No. 1 economic driver. The center's team at Georgia Tech conducts cutting-edge research in fields such as astrophysics, Earth science, planetary science, robotics, space policy, space technology, materials science, and space systems engineering.

CSTAR boasts a collaborative network of more than 100 Georgia Tech faculty members and research staff, supported by annual funding exceeding $20 million. Its contribution to space research is highlighted by its active multiyear research grants totaling over $100 million. Each year, CSTAR also contributes to the academic community with around 100 peer-reviewed journal articles and provides mentorship to dozens of graduate and undergraduate students, shaping the next generation of space research.

Members of CSTAR have contributed to a variety of spaceflight projects, from observing the atmosphere of Jupiter, to creating carbon nanotube-based technology on CubeSats, to building an innovative, dual-use antenna that is simultaneously a critical life-saving handrail and a radio emitter inside an airlock on the International Space Station. Several examples of this research will soon be part of a new permanent display in the National Air and Space Museum in Washington, D.C. 

“The work done by the Georgia Tech research community in space is phenomenal,” said CSTAR Director Jud Ready. “We have worked on the International Space Station, launched numerous free-flying CubeSats in low Earth orbit, as well as our current crowning achievement, the Lunar Flashlight CubeSat, which is the world’s only heliocentric spacecraft currently owned and operated by an academic institution that recently demonstrated planetary optical navigation techniques for the first time, by any organization — including NASA.” Future missions include materials demonstrations on a lunar lander, as well as additional orbital activities of both the Earth and moon.

“The SRI will increase our reach and impact over and above these prior activities by at least an order of magnitude,” he said. “I am excited for what the future holds for Georgia Tech students, faculty, and research partners as a result of this new organization.”

Center for Relativistic Astrophysics

The Center for Relativistic Astrophysics (CRA) is housed within the College of Sciences’ School of Physics. The center’s mission is to provide students with education and training in the key research areas of astroparticle physics, theoretical astrophysics, and gravitational wave astrophysics. 

CRA researchers study the breadth of space, ranging from the early universe’s large-scale structure to particle interactions. They also study black holes and the merger of compact objects, the potential outcome of the evolution of stellar binary systems, and — closer to home — exoplanets and stars found in the Milky Way. Of particular strength are computational astrophysics and multi-messenger astrophysical studies with neutrinos, photons, and gravitational waves. 

In addition, CRA researchers actively participate in major international collaborations, such as the operations and development of existing and future detectors, including the IceCube Neutrino Observatory, the LIGO and LISA gravitational wave observatories, X-ray observatories NuSTAR and Athena, and gamma-ray detectors VERITAS and CTA.

“Bringing together all space research under a single umbrella will be a huge boon to the CRA’s research efforts and visibility,” said John Wise, CRA director. “I am excited about the opportunities the SRI will bring forth within such a collaborative environment, especially the prospect of Georgia Tech leading a space mission that can test the theoretical work performed within the CRA.”

Georgia Tech Astrobiology

Astrobiology research at Georgia Tech, which includes experts in biochemistry, physics, aerospace engineering, planetary science, and astronomy, as well as others, seeks to answer these age-old questions: What is the origin of life? Does life exist on other worlds?

Georgia Tech’s astrobiology community includes students, staff, and faculty across campus, the educational curriculum, the Exploring Origins student-run group, an astrobiology fellows program, and keystone events. 

Many globally recognized researchers in this field are at Georgia Tech, and their recent discoveries hint at the potential for life on Mars and ocean worlds like Europa. Astrobiology at Tech brings together these faculty with scholars in the humanities and social sciences to share their research with the public and give it a broader cultural context. 

The Georgia Tech Astrobiology Graduate Certificate Program, an interdisciplinary initiative across several Schools and Colleges, is designed to broaden student participation in astrobiology. An undergraduate minor is in development. The purpose of these programs is to expand opportunities for both undergraduate and graduate students in the interdisciplinary field of astrobiology.

“One of the main reasons I came to Georgia Tech in 2020 is its vibrant astrobiology program,” said Christopher E. Carr, co-director of Georgia Tech Astrobiology. “It’s a true pleasure to have such amazing colleagues.”
