Newswise \u2014 When we check the weather forecast, that information comes from satellites. When we FaceTime a friend, that call could come via satellites. From cellphone networks to national security systems, satellites are vital to our connected globe. Yet regulating how satellites function across borders is almost as complicated as the technology that launches them into space. Researchers in Georgia Tech\u2019s Space Research Institute<\/a> are shaping how satellites operate, both scientifically and politically.<\/p>\n

Satellites aren\u2019t the only technology Georgia Tech applies to terrestrial problems. Researchers are using gravity experiments to improve energy storage and are discovering lessons from science fiction. This Institute-wide work proves space isn\u2019t the final frontier in paradigm-shifting research \u2014 it\u2019s a bridge.<\/p>\n

Reading Into Possibility<\/p>\n

To\u00a0imagine technology not just for our planet but the rest of the galaxy, scientists need inspiration. This is where Lisa Yaszek<\/a>\u2019s work comes in. As Regents\u2019 Professor of Science Fiction Studies in the School of Literature, Media, and Communication<\/a> (LMC), Yaszek studies how science fiction stories reflect and influence actual science and technology. To Yaszek, these are not mere stories.<\/p>\n

\u201cIn the last 200 years, science fiction has become a common global language we can use to speak to each other across centuries, continents, and cultures,\u201d she said.<\/p>\n

This type of storytelling is also paramount for the scientific profession. Scientists need to tell compelling narratives and describe possible futures when writing grant applications. Science fiction or not, stories are fundamental. To that end, Yaszek has partnered with faculty members from the Georgia Tech Research Institute<\/a> (GTRI) and the Jimmy and Rosalynn Carter School of Public Policy<\/a> to examine how storytelling affects public understanding of nanoscience and technology. She has also hosted imagineering sessions for materials scientists, space researchers, and science fiction authors at local events and international conferences. Her expert commentary on science fiction as a window into scientific and technological history has appeared in numerous prominent publications.<\/p>\n

\u201cScience fiction is a genre that teaches students how to think through the potential impact of science and technology on people. I want my students to ask, \u2018What are the steps you take to make that future happen?\u2019\u201d \u2013Lisa Yaszek<\/p>\n

She is currently collaborating with colleagues from LMC, the School of Earth and Atmospheric Sciences, the School of Music, and the Office of Student Engagement on a grant-funded event series called \u201cThe Art of Failure.\u201d This series brings together scientists, artists, and students to explore the role of failure in technoscientific progress, culminating in a student-centered art show.<\/p>\n

Yaszek also shares her expertise with students in majors across the Institute, who often find that the futuristic characters they read about are grappling with issues similar to today\u2019s. A biomedical engineering student focused her research on reproductive technology design after helping Yaszek compile a feminist science fiction anthology. The stories helped the student realize that reproductive health could be more affordable and male-friendly \u2014 and that she could contribute.<\/p>\n

\u201cThis is a genre that teaches students how to think through the potential impact of science and technology on people,\u201d Yaszek said. \u201cI want my students to ask, \u2018What are the steps you take to make that future happen?\u2019\u201d<\/p>\n

Defying Gravity<\/p>\n

\u00c1lvaro Romero-Calvo<\/p>\n

Gravity isn\u2019t an all-or-nothing state. Orbiting spacecraft experience microgravity, which is\u00a0a near-weightless state. Astronauts bouncing off the lunar surface are subject to low gravity \u2014 1\/6th of the Earth’s gravity. Because liquids and gases behave very differently in these environments, space engineers and astronauts need assurance that propulsion, life support, and thermal systems will behave as intended when gravity is turned off. In his lab, Daniel Guggenheim School of Aerospace Engineering<\/a> (AE) Assistant Professor \u00c1lvaro Romero-Calvo<\/a> studies how these and other substances behave in low-gravity conditions.<\/p>\n

\u201cI see microgravity as a magnifying glass that allows us to study fundamental physical phenomena of relevance to a wide range of technologies in space and on Earth,\u201d he said.<\/p>\n

One of these areas is renewable energy. Energy from weather-dependent sources like solar or wind power needs to be reliably and safely stored as these technologies become more prevalent. Hydrogen storage can help convert electric energy to chemical energy via water electrolysis, but keeping bubbles out of these cells is crucial, which is also a problem in microgravity environments.\u00a0<\/p>\n

Romero-Calvo\u2019s research group uses parabolic flights that mimic microgravity conditions to test these bubbly flows. They are also constructing a drop tower \u2014 which will be available to the entire campus \u2014 to test how any object or system behaves when dropped while experiencing a microgravity environment.<\/p>\n

\u201cWe are working very intensely to bring humans to the moon and Mars, but we are also developing technologies that can be used to produce hydrogen on Earth much more efficiently and much more reliably,\u201d he said.<\/p>\n

Just as gravity isn\u2019t binary, neither is research intended for space. With Romero-Calvo\u2019s work, humans in space and on land will benefit. His work is funded by NASA, the Defense Advanced Research Projects Agency, and industry partners.<\/p>\n

Propelling the Future<\/p>\n

Mitchell Walker II<\/p>\n

Satellites make our world run, but keeping them in orbit is trickier than it seems. Although satellites float in space, they\u2019re still affected by what happens on Earth. A rainy season in Brazil can shift Earth\u2019s gravity and disturb a satellite orbiting the planet. This is why researchers like Mitchell Walker II<\/a>, the William R.T. Oakes Jr. School Chair in AE, study propulsion. Space propulsion, a method to accelerate spacecraft, ensures these satellites stay in the correct orbit.<\/p>\n

At its most basic, Walker\u2019s research focuses on the physics of plasma \u2014 ionized gas composed of electrons. Plasma physics helps propel satellites in space, and effectively harnessing a satellite\u2019s electrical power is vital to keep satellite services operational. Walker\u2019s research partners in the military, civilian, and commercial spaces need this knowledge to understand where they can put satellites and how close together, particularly\u00a0as space gets more crowded.<\/p>\n

\u201cEvery time something in space propulsion research changes, it pushes us to a new application and new regime for physics,\u201d Walker said.<\/p>\n

Infrastructure to keep satellites in orbit and to maintain a presence on the moon or Mars is becoming increasingly vital. Walker sees this moment as an inflection point in the space economy, comparing it to when railroads finally connected the West and East Coasts of the U.S. in the 19th century. The railroads helped send supplies and build out the West Coast, and propulsion will have a similar advantage for space. Whoever can get the most satellites in orbit \u2014 and keep them there \u2014 will have the advantage.<\/p>\n

Walker\u2019s work is funded by NASA, the Air Force, and industry partners.<\/p>\n

Keeping Space Safe<\/p>\n

Thomas Gonz\u00e1lez Roberts<\/p>\n

Space may seem infinite, but there are limits. How countries decide where to send satellites is a crucial international affairs issue. Not only does the physical location of a satellite matter, but so do the radio frequencies it emits to ensure clear communication. Like any domain, space needs policies for safety and fair use.<\/p>\n

\u201cThe space domain is the newest of the physical domains, and it’s ripe for geopolitical conflict,\u201d said Thomas Gonz\u00e1lez Roberts<\/a>, an assistant professor in the Sam Nunn School of International Affairs<\/a> and AE. \u201cSpace systems already enable ground, air, and sea conflict, but there’s never been a foreign state satellite attack after which that state claimed responsibility \u2014 yet.\u201d<\/p>\n

Roberts studies how to prevent space conflict and mitigate the damage if tensions rise. He pursues this from technical aspects, such as characterizing space systems\u2019 vulnerabilities to disruption and degradation. He also looks at political aspects, like a country starting an arms race in space. Roberts wants to train engineers, who can already answer technical questions, to influence space policy. His students often analyze raw satellite data to detect satellite motion and predict their behavior.<\/p>\n

\u201cA better world is one in which we have a secure space domain that’s free from international geopolitical conflict,\u201d Roberts said.<\/p>\n

Satellite Spatial Awareness<\/p>\n

Legislating satellite trajectories in policy is one thing, but ensuring they have clear paths in space is another. Brian Gunter<\/a>, an associate professor in AE, leads the Orbital Calibration 2 Mission<\/a> (OrCa2) satellite mission. OrCa2\u2019s goal is to send two small satellites, called CubeSats, into space. These CubeSats have special reflective panels that can be used to develop improved methods for tracking space objects. One of the satellites (OrCa2a) also carries a camera that will track other space objects from orbit, including the second OrCa2 satellite (OrCa2b). This mission is designed to accurately track space objects so that future collisions between space objects (like debris and other satellites) can be avoided.<\/p>\n

\u201cThis project is all about space domain awareness,\u201d Gunter said, \u201cproviding space object tracking information in an effort to improve space traffic coordination and reduce the collision risk of current and future space object populations.\u201d<\/p>\n

Gunter\u2019s research is funded by NASA, the Aerospace Corporation, and GTRI\u2019s independent research and development programs<\/a>.<\/p>\n

Sharing Satellites\u2019 Savvy<\/p>\n

When we think of satellites, we often envision them taking photos of landscapes, but satellites can also give up-to-date information on resource allocation: What crops are stressed? What areas have groundwater? Where are populations in underserved areas? All of this information can be vital to policy decisions, but only if everyone has access to it.<\/p>\n

Earth observation satellites are constantly collecting data, but who has access to that data? NASA\u2019s data is public, but most private companies \u2014 and even some other countries \u2014 don\u2019t widely share their information. Mariel Borowitz<\/a>, associate professor in the Nunn School of International Affairs, studies satellite data transparency to understand how the open availability of information benefits from satellite programs.<\/p>\n

\u201cNo one entity can collect all the data we need to understand complex issues like climate change,\u201d Borowitz said. \u201cWhen data is shared openly, we can improve global understanding.\u201d<\/p>\n

Borowitz has researched the benefits this shared data can have for society. Working with the Gates Foundation, she examined a case in which satellite data helped provide more accurate population maps. These maps enabled polio vaccination teams to find previously underserved populations in Nigeria, accelerating the effort to eradicate polio and resulting in millions of dollars in cost savings. With appropriate transparency, satellites can collect data that could change the world for the better.<\/p>\n
