Roger Wiens is a planetary scientist and Fellow at ‪@LosAlamosNationalLab‬. He is the principal investigator for both the ChemCam instrument aboard the Mars Curiosity rover and the SuperCam instrument, aboard the Perseverance rover. The SuperCam on NASA's Perseverance rover examines rocks and soils with a camera, laser and spectrometers to seek organic compounds that could be related to past life on Mars. It can identify the chemical and mineral makeup of targets as small as a pencil point from a distance of more than 20 feet (7 meters)

Mehmet S. Tosun is the Barbara Smith Campbell Distinguished Professor at the University of Nevada, Reno (UNR). He is also a Professor of Economics and the Director of International Programs in the College of Business. His research interests and expertise include public finance (particularly tax policy), regional economics, and economics of population and demography. The billionaires Richard Branson and Jeff Bezos have recently successfully reached the edge of space. Dr. Tosun of the College of Business at the University of Nevada, Reno, discusses the impact of these flights on the space economy.

Anders Johansen is a Professor of Astronomy at Lund Observatory at Lund University in Sweden, working there on topics such as planet formation, accretion discs, turbulence, and supercomputing. He obtained his PhD in 2007 at Max Planck Institute for Astronomy in Heidelberg. After that he spent a bit more than two years as a postdoc at Leiden Observatory. Anders obtained his docent degree from Lund University in 2013. According to a study led by ProfessorJohansen, Earth, Venus and Mars were created from small dust particles containing ice and carbon. The discovery opens up the possibility that the Milky Way may be filled with aquatic planets.

Hai-Bo Yu is an associate professor of physics and astronomy at the University of California, Riverside. His main research fields are: theoretical particle physics and astrophysics. Supermassive black holes, or SMBHs, are black holes with masses that are several million to billion times the mass of our sun. Hai-Bo Yu from the ‪University of California‬, Riverside, sheds more light on the origin of these massive and mysterious objects.

Dr. Konstantin Getman received an honor master's degree in astronomy at Moscow State University in 1994 and his Ph.D. degree in physics and mathematics at Pushkov Institute of Terrestrial Magnetism, Ionosphere and Radiowave Propagation of the Russian Academy of Sciences in 1999. Since 2001, he has been at the Pennsylvania State University where he is currently a research professor. His research is focused on star formation and stellar activity. By conducting the largest survey ever of star-forming regions in X-rays, a team of researchers led by Dr. Getman of the Pennsylvania State University (PSU) has helped outline the link between very powerful flares, or outbursts, from youthful stars, and the impact they could have on planets in orbit.

Diana Dragomir is an assistant professor at the Department of Physics and Astronomy of the University of New Mexico. Her research focuses on the demographics and atmospheres of exoplanets smaller than Neptune. She is particularly interested in super-Earths and sub-Neptunes, planets with radii between those of the Earth and Neptune. A team of astronomers, including Dragomir of the University of New Mexico, has recently discovered a new exoplanet orbiting a nearby star. The newfound alien world, designated TOI-1231 b, is Neptune-sized, with a radius nearly four times greater than that of the Earth.

Christopher Prior is an Addison-Wheeler fellow in the Mathematical sciences department at Durham University. His general interests lie in mathematical modelling and the mathematical issues on the borderline between geometry and topology. He has a particular interest in physical systems for which the conservation of topology of inter-twined bundles or tubular structures is a key consideration. Prior and colleagues have come up with a new way to measure the entanglement of the magnetic field of the Sun. These twisted magnetic fields rise to the convection zone of the Sun and cause solar flares.

Up Close & Personal Never Gets Old: Former Chief NASA Administrator (2018-2021) Jim Bridenstine was the keynote speaker for the World Ag Expo's opening ceremony a few years back, providing an overview of the ways NASA is supporting agriculture. What an inspiration - foresight in 2019 is alive and thriving today in NASA, as applicable today as it was then.
