Reaching Further for the Stars /news/reaching-further-for-the-stars/ Tue, 21 Nov 2023 18:21:18 +0000 /news/?p=138058 Key moves made in the early 2000s allowed 麻豆原创 to expand its space research profile and push research ideas to new heights.

]]>
Since its founding in 1963, 麻豆原创 has had close ties to the space industry. In the early 1990s, 麻豆原创 professors would go to Kennedy Space Center to teach graduate programs to NASA employees. When NASA鈥檚 budgets were cut, 麻豆原创 proposed to NASA to research nondestructive testing methods so the agency wouldn鈥檛 have to destroy rocket engines and shuttle tiles, saving money. By the 1980s, it was estimated that 麻豆原创 graduates comprised at least 30% of the workforce of NASA鈥檚 Kennedy Space Center and its partners, according to Ray Lugo 鈥79, an aerospace engineering alum and Center for the Advancement of Science in Space chief operating officer.

As the university grew in enrollment over the decades, so did the programs around the campus, as well as the campus itself. Space research was part of the expansion. While 麻豆原创 had done research and served as a talent pipeline for the space industry, the administration wanted to extend its reach even further. In August 2002, Humberto Campins, Pegasus Professor in the Department of Physics, joined the university as provost research professor of physics and astronomy and head of the Planetary and Space Science Group. Campins joined the university with an extensive research background in asteroids, comets and small planetary bodies. While at the University of Arizona from 1998 to 2002, he was part of a team that submitted a proposal that became the OSIRIS REx mission,聽the first U.S. mission to collect a sample from an asteroid.

Campins would be tasked with developing the planetary sciences program, though it took a few times to get him to join 麻豆原创. As Florida Space Grant Consortium director from 1994 to 1998, Campins got to know former professor and department chair Brian Tonner. Tonner pitched the opportunity to Campins, but he had started his job as the program officer at the Research Corporation and as research faculty at the Lunar and Planetary Laboratory of the University of Arizona in Tucson. However, Campins would get a final offer that would lead to him considering moving to Orlando.

鈥淚 liked my job in Tucson, and I turned them down, and then that turned into another invitation and another,鈥 Campins says. 鈥淚 had another invitation to attend a workshop on physics pedagogy. I attended a workshop that turned into a third offer that was good enough that I said, 鈥榊ou know what? I might want to take a chance.鈥欌

Lifting Off

Campins’ first two hires brought extensive planetary science research behind them. In 2003, Dan Britt joined 麻豆原创 as a professor of astronomy and planetary sciences, having worked on the Mars Pathfinder mission and done large-scale asteroid research. In 2005, Yan Fernandez was hired as an assistant professor in physics, having studied comets and asteroids for 11 years prior.

The following year, two hires would expand the physics department and 鲍颁贵鈥檚 space research goals as Joshua Colwell and Joe Harrington were hired as assistant professors. Colwell came to the university having worked on the NASA Cassini mission since some of its earliest planning stages in 1990 and was part of the design and observation planning for the Ultraviolet Imaging Spectrograph, or UVIS, on the multi-instrument spacecraft. In 2019, Colwell and Richard Jerousek ’06 ’09MS ’18PhD, a former student of Colwell and current physics department lecturer, used UVIS data recorded by Cassini to measure and describe the structure of Saturn鈥檚 largest innermost ring, the C Ring.

Harrington led the Spitzer Exoplanet Target of Opportunity Program, which measured exoplanet eclipses and transits with the Spitzer Space Telescope. He was also part of the development of the Bayesian Atmospheric Radiative Transfer, an open-source, reproducible research code for inferring the properties of exoplanet atmospheres, for which he won the 2011 College of Sciences Excellence in Research Award.

Britt, Colwell and Harrington are now Pegasus Professors, with Colwell as physics department chair and Harrington associate vice president for research.

Raising the Profile

As with many start-ups, there were early challenges in developing the planetary sciences program. However, with help from the administration, such as Tonner, M.J. Soileau, CREOL鈥檚 founding director, and Michael Johnson, then-dean of the College of Sciences and current provost and executive vice president for Academic Affairs, the program was able to grow over time. The research also helped increase the university’s profile, which helped administrative support.

The 2010s saw 鲍颁贵鈥檚 space research evolve through their partnerships with various institutions. In 2012, the Florida Space Institute (FSI) was re-chartered to allow for an extensive research portfolio. That same year, FSI was also relocated from near NASA鈥檚 Kennedy Space Center to the Central Florida Research Park in Orlando, closer to 麻豆原创 and its research efforts. FSI also managed the Arecibo Observatory in Puerto Rico, the largest fully operational radio telescope on the planet, leading to enhanced planetary research and discoveries such as a聽moon orbiting a near-Earth asteroid. Recently, Noemi Pinilla-Alonso an associate scientist at FSI, was part of a team studying the聽size and composition of Dinkinesh, an asteroid NASA鈥檚 Lucy mission visited this month. Britt is part of the science team for the mission.

A year after FSI was re-chartered, 鲍颁贵鈥檚 Center for Lunar and Asteroid Surface Science (CLASS) launched via a $6 million NASA grant in 2013. CLASS facilitated one of 鲍颁贵鈥檚 key space contributions: The Exolith Lab. The lab develops and produces Martian, lunar and asteroid regolith simulants and works with NASA in addition to conducting its own research, led by Britt, Zoe Landsman 鈥11 鈥17PhD and Anna Metke.

鲍颁贵鈥檚 Martian formula is based on the chemical signature of the soils on Mars collected by the Curiosity rover, allowing researchers to have a more accurate simulant for the many research uses, such as plant growth, vehicle testing, processing and more.

鈥淚t’s really important to have a good handle of the mineralogy of the stuff you鈥檙e going to be working with because that really dictates the chemistry and the physical properties of the surface you鈥檙e going to be working on,鈥 Britt says.

Research Now and Beyond

Recent studies are pushing 鲍颁贵鈥檚 understanding of space even further. In 2020, Kareem Ahmed, an assistant professor in 鲍颁贵鈥檚 Department of Mechanical and Aerospace Engineering, and his team developed a聽new rocket propulsion system, leading more power to be generated from the rocket, traveling further while using less fuel and burning cleaner. In 2021, aerospace engineering Associate Professor Tarek Elgohary, along with his research students, used analytical and computational methods and machine learning to ensure聽spacecraft don鈥檛 collide with each other or space junk. The research is supported by the Federal Aviation Administration and Lockheed Martin Space.

Last year, Associate Professor Ranajay Ghosh and his team discovered a way to turn聽lunar regolith into 3D-printed bricks that could be used during space colonization. Using lunar regolith from the Exolith Lab, the bricks were made by 3D printing and binder jet technology (BJT), an additive manufacturing method that forces out a liquid binding agent (in this case, saltwater) onto a bed of powder.

Future space research will see Professors Kerri Donaldson Hanna and Adrienne Dove lead a robotics mission studying the聽moon鈥檚 Gruithuisen Domes, a previously unexplored area. Launching in 2026, the researchers will examine the domes鈥 makeup and how dust interacts with the spacecraft and a rover. The $35 million mission will help inform future robotic and human exploration of the moon and may also help researchers better understand Earth鈥檚 history and other planets in the solar system.

For Donaldson Hanna, the range of planetary science research within the physics department drew her to 麻豆原创. She saw intriguing ways she could collaborate with people on various research possibilities.

鈥淛ust seeing how committed to space science and space exploration the university itself is, it’s certainly nice and fun to be in an environment where what you鈥檙e doing is celebrated and is exciting,鈥 Donaldson Hanna says.

While 麻豆原创 has worked with the space industry since its inception, the work done in the early 2000s helped take the university’s space research closer to the stars. From bringing in new faculty to help shape emerging departments to administrative decisions that would provide an immersive environment for space research, this period began a new era that saw Knight researchers Charge On to further understand our universe.

Students and community members got a nice view of the planet Neptune and its biggest moon Triton during one of September鈥檚 Knights Under the Stars events hosted at 鲍颁贵鈥檚 Robinson Observatory.

It was an early look at the planet, which today celebrates its 175th birthday.

鈥淚 did a Neptune project all the way back in my undergraduate days,鈥 says 聽. 鈥淚t was my first real astronomy project. Even today, it鈥檚 quite a mystery. There are several mission concepts out there and there鈥檚 a highly motivated group of astronomers pushing them, but there are no approved missions 鈥 yet.鈥

Joe Harrington

Despite the passage of time, the blue planet continues to captivate planetary scientists worldwide.

It is the narrowest of the gas giants and the furthest major planet out from the sun since Pluto was reclassified to a dwarf planet. Data from observations lead scientists to believe that Neptune is made up of gases and ice with a rocky core. Gravity is expected to be very close to what we experience on Earth because while Neptune has 17 times more mass than Earth, it is also four times larger than our planet. Distance is a challenge too. It would take about nine years to send a spacecraft to the planet with current technology.

There鈥檚 only been one flyby of the planet, completed by NASA鈥檚 Voyager 2 in 1989. It was a quick run and produced some stunning, but puzzling photos that left more questions than it answered.

The planet has also been studied from afar using the Keck, Hubble, and Spitzer telescopes, but it and its moon Triton still hold many secrets, says Assistant Professor of Physics Theodora Karalidi.

鈥淣eptune 鈥 in a way, it is the closest thing we have to a brown dwarf in the solar system,鈥 Karalidi says. 鈥淚f finding life outside our planet is of interest, then exploring Neptune should be of interest. A 鈥榞ood鈥 atmosphere is important. The more we learn about atmospheres in our solar system, from the Earth to Venus, Mars, Jupiter, and Neptune, the more we can understand atmospheres and differentiate between a planet that can support life from one that cannot. By learning what the key features of different types of clouds, chemistry or atmospheric circulation patterns are in our observations from a distance, and how they compare with observations from up-close, we can make more informed decisions on which planets to stare at for longer periods to see if they have life, even when we have a single pixel to work with.鈥

Karalidi specializes in atmospheres of other planets. She鈥檚 eager to see what Neptune and Triton can tell us about life formation.

麻豆原创 Planetary Scientist Theodora Karalidi.

鈥淭riton 鈥 one of the moons of Neptune 鈥 is an intriguing, active body that could host an ocean. This could make it a great location to search for life outside the Earth,鈥 she says. 鈥淚f it could host life, understanding Neptune would again be important. The magnetic field of Neptune for example, is weird but we don鈥檛 know why. As magnetic fields can be friends and foes to life, how could that affect life on Triton? Also, understanding the weird field of Neptune could also inform us about planetary magnetic fields in general, their interaction with solar wind and cosmic rays, and in extension our own magnetic field and our protection from those factors here on Earth.鈥

Neptune and Triton will remain visible with telescopes throughout winter. There are Knights Under the Stars events scheduled in October and again in November where the public can see these objects and others through several telescopes set up at the Robinson Observatory 鈥 at no cost. Participants also get a chance to ask questions and get some pointers from 麻豆原创 faculty and students in the planetary sciences program.

鈥淲e love sharing the wonder of space,鈥 says Yan Fernandez, a physics professor and director of the observatory. 鈥淭hat鈥檚 how a lot of us got into space related work. It was simply looking up and seeing how big it is out there and realizing we have so much to learn.鈥

Record Number of 麻豆原创 Students Presenting at National Space Conference /news/record-number-of-ucf-students-presenting-at-national-space-conference/ Mon, 07 Oct 2013 18:50:33 +0000 /news/?p=53785 麻豆原创 is breaking a record this week with 22 people presenting at one of the most important planetary sciences conferences in the nation.

The annual Division for Planetary Sciences meeting kicked off in Denver on Saturday drawing thousands of scientists from around the world who study the solar system and its early formation. DPS is the largest professional organization of planetary scientists and is part of the American Astronomical Society.

Nineteen students and three faculty members are presenting findings at the meeting, through Oct. 11, which is a school record, said Daniel Britt, a professor of physics at 麻豆原创 and a former chair of DPS. 聽The most students to attend in previous years had been 15.

麻豆原创 students also snagged more than 50 percent of the free travel money available to students nationwide to attend the meeting thanks to their stellar work in the field and their early applications, Britt added.

鈥淚t鈥檚 quite a year for us,鈥 Britt said. 鈥淚t鈥檚 very exciting. We are well represented.鈥

The undergraduate and graduate students will present on a range of topics from detailed studies of asteroid impacts to an analysis of bending waves found within Saturn鈥檚 rings.

For example, physics doctoral student Tracy Becker is presenting a talk about the rings of Saturn. She analyzed data from the Ultraviolet Imaging Spectrograph, an instrument on the Cassini spacecraft that is currently orbiting Saturn, to measure the size and population of small particles in Saturn’s A ring. Constraints on the particle sizes in the rings contribute to the overall understanding of the origin and evolution of the Saturnian ring system, with applications in exploring planet formation, proto-planetary disks, and the structure of galaxies.

Students in physics professor Joe Harrington鈥檚 Exoplanets Group will present on a wide range of research related to the more than 1,000 planets discovered outside our solar system, which was made possible in the past few years thanks to a variety of modern instruments such as NASA鈥檚 Spitzer Space Telescope. They include:

  • Sarah Blumenthal, a 麻豆原创 junior majoring in chemistry with a minor in mathematics, is presenting a poster on Exoplanet Atmosphere Equilibrium Chemistry Calculations. The study predicts the molecules formed in the atmospheres of giant exoplanets (like methane and water) at different distances from their star, assuming different amounts of the most common elements (such as hydrogen, carbon, and oxygen).
  • Ryan Hardy, who graduated from 麻豆原创 this past summer, will present a poster on Spitzer measurements of a giant exoplanet, called HAT-P-13b.聽By comparing the planetary orbit from his own measurements with earlier measurements, he was able to determine, based on the theory of tides altering a planet’s orbit, that the planet has a very small, if any, rocky core.聽聽He also determined that the temperature in the atmosphere increases with depth, which was expected but is not always found in the region of the atmosphere that the telescope can measure.
  • 麻豆原创 graduate student Patricio Cubillos will present a study of numerical methods that have been applied to analyzing exoplanet data.聽聽麻豆原创 Sophomore Andrew Foster has determined the orbits of two exoplanets, and will present the results of his work.
  • Oliver Bowman, a 麻豆原创 senior, has studied the atmosphere of exoplanet HAT-P-16b with Spitzer.聽He has improved the orbit determination for the planet and has determined the temperature of its atmosphere.
  • Attending the conference gives students an opportunity to interact with other leading scientists in the field and giving presentations provides them invaluable experience, Britt said.

    ]]>
    The 麻豆原创 has detected what could be its first planet, only two-thirds the size of Earth and located right around the corner, cosmically speaking, at a mere 33-light years away.

    鈥淲e have found strong evidence for a very small, very hot and very close-by planet with the help of the Spitzer Space Telescope,” Kevin Stevenson 鈥12PhD says.

    The exoplanet candidate, called 麻豆原创 1.01, is close to its star, so close it goes around the star in 1.4 days. The planet鈥檚 surface likely reaches temperatures of more than 1,000 degrees Fahrenheit. The discoverers believe that it has no atmosphere, is only two-thirds the gravity of Earth and that its surface may be volcanic or molten.

    鈥淲e have found strong evidence for a very small, very hot and very close-by planet with the help of the Spitzer Space Telescope,” said Kevin Stevenson 鈥12PhD, a lead author of the paper, which appears online tomorrow in The Astrophysical Journal. 鈥淭his discovery is a significant accomplishment for 麻豆原创.鈥

    Stevenson and his colleagues were studying a hot-Neptune exoplanet, designated GJ 436b, already known to exist around the red-dwarf star GJ 436, when data revealed clues that led them to suspect there could be at least one new planet in that system, perhaps two.

    The team noticed slight dips in the amount of infrared light streaming from the star. A review of Spitzer archival data showed that the dips were periodic, suggesting that a planet might be blocking out a small fraction of light as it passed in front of GJ 436, as seen from Earth.

    鈥淚 could see these faint dips in the starlight and I wanted to determine their source. I knew that if these signals were periodic, they could be from an unknown planet,鈥 said Stevenson, who is now a postdoctoral scholar at the University of Chicago.

    So he, professor Joseph Harrington and 麻豆原创 graduate student Nate Lust began looking at the data. They sifted through hundreds of hours of observations collected from Spitzer, the Deep Impact spacecraft, the ground-based Very Large Telescope in Chile and the Canada-France-Hawaii Telescope near the summit of Mauna Kea in Hawaii.

    This transit technique, used by a number of telescopes, including NASA鈥檚 Kepler space telescope, relies on these tiny, partial eclipses to find exoplanet candidates. Spitzer has performed science work on known exoplanets before, but 麻豆原创-1.01 represents the first time Spitzer has made a transit discovery.

    With the finding of 麻豆原创-1.01, GJ 436 is likely now home to the first multi-transiting-planet system described by a mission other than Kepler. Of the 1,800 stars identified by Kepler as candidates for having planetary systems, only three are verified to contain sub-Earth size exoplanets.

    The depth and duration of a transit reveals basic properties of an exoplanet, such as its size and distance from a host star. In 麻豆原创-1.01鈥檚 case, its diameter is estimated at 5,200 miles, or two-thirds that of Earth, placing the world among the smallest on record. The team also noticed hints of yet another potential planet dubbed 麻豆原创-1.02, but its period was impossible to estimate.

    So why aren鈥檛 scientists calling 麻豆原创-1.01 a planet?

    A measured mass is needed to verify that these objects are planets, but even the most sensitive instruments currently available are unable to measure exoplanet masses this small.

    鈥淒espite the lack of a confirmed mass, the team is confident future observations will verify our findings,鈥 Harrington said.

    Spitzer scientists are eager to see what the future will bring.

    鈥淚 hope future observations will confirm these exciting results, which show Spitzer may be able to discover exoplanets as small as Mars,鈥 said Michael Werner, Spitzer Project Scientist at JPL. 鈥淓ven after almost nine years in space, Spitzer鈥檚 observations continue to take us in new and important scientific directions.鈥

    Others who contributed to the study include: Nikole Lewis (University of Arizona), Guillaume Montagnier (European Organisation for Astronomical Research in the Southern Hemisphere), Julianne Moses (Space Science Institute), Channon Visscher (Southwest Research Institute) and 麻豆原创 students Jasmina Blecic, Ryan Hardy, Patricio Cubillos and Christopher Campo.

    Stevenson earned his bachelor鈥檚 degree in physics from Simon Fraser University and a master鈥檚 degree in astronomy from the University of Western Ontario. In May 2012, he earned his Ph.D. in physics (planetary sciences track) from 麻豆原创 and earned the Order of Pegasus for his high academic and professional achievements as well as his service to the community. He has published articles in Nature and The Astrophysical Journal.

    Harrington joined 麻豆原创 in 2006 and is now an associate professor in the planetary sciences group. Previously he was at Cornell University for almost 10 years. He has multiple degrees from the Massachusetts Institute of Technology. Harrington鈥檚 research interests include planetary and exoplanetary atmospheres, comet impacts into atmospheres, astronomical data analysis methodology and infrared observing techniques.

    Lust is a graduate student in the department of physics at 麻豆原创.
