Episode 4 - "Pushing the Boundaries of Human Spaceflight"

Wed, 07 Apr 2021 19:03:27 -0000

Episode Notes

On today's episode we have Emmanuel Zamora, or Alex, as his friends call him. Alex is currently an electrical engineer working at NASA's Johnson Space Center. He was born and raised in the great city of Brownsville, Texas, graduated from Hanna High School, and received a degree in electrical engineering from the University of Texas at San Antonio. His experience as an electrical engineer includes an internship at the Brownsville Public Utilities Board, a job at CPS Energy, and then landing an opportunity as a sub-contractor for NASA on the International Space Station program, where he provided engineering support for the space station's electrical power system, or EPS. More specifically, for the Spartan Controller at Mission Control at NASA's Johnson Space Center. Alex recently stepped into his new role as a NASA civil servant in January of this year 2021, where he oversees and implements policies over numerous programs. His long-term goal is to become a flight director.

Episode 3 - "Roughing It as an Astronomer"

Mon, 15 Mar 2021 05:00:00 -0000

Episode Notes

Our guest this episode is our collaborator, colleague, and friend, Moises Castillo. A Brownsville and Los Fresnos native, Moises attended university and earned a bachelor of science in physics from the University of Texas Rio Grande Valley, during which he also worked as lab manager in the Physics Department. Moises earned a masters of science in physics from UTRGV in 2019. He's been the assistant director of the Cristina Torres Memorial Observatory, where he observed and studied eclipsing binary star systems, as well as a researcher for the Center for Gravitational Wave Astronomy at UTRGV working under Mario Diaz. Currently he's stepping into his role as the Event Coordinator for the Space and Science Team of the South Texas Astronomical Society. He's a curious explorer of the world, a talented engineer and astronomer, the authoritative MC voice, and a great travel partner and friend.

Episode 2 - "Gravitational Waves and the Giant Shazam"

Mon, 01 Mar 2021 15:43:35 -0000

Episode Notes

This is Receding Horizons, Episode 2, where we talk about the exciting era of gravitational wave observations and multi-messenger astronomy.

Brina Martinez is an undergraduate studying physics and computer science at the University of Texas Rio Grande Valley. She is currently a research assistant at the Center for Gravitational Wave Astronomy and in the Time Domain Astronomy Group operating the Cristina Torres Memorial Observatory, both under the mentorship of Dr. Mario Díaz. Brina is a published scientist. Her research focuses on characterizing noise sources intrinsic to the Laser Interferometer Gravitational-Wave Observatory, or LIGO. She has participated in a research experience for undergraduates at Louisiana State University under Dr. Guillermo Valdes and Dr. Gabriela González, and was a LIGO undergraduate fellow at Caltech under Dr. Derek Davis. Brina is a board member and resident astrophysicist at the South Texas Astronomical Society, as well as a board member and secretary at the Brownsville Chapter of the Society of Physics Students. She was the recipient of several awards including a scholarship from the Society for Advancement of Chicanos/Hispanics and Native Americans in Science, and a Victor M. Blanco Fellowship from the LIGO Lab and National Society of Hispanic Physicists. She is a gifted public speaker, and I've had the privilege to work with her (and make a lot of memories) during my time in Brownsville.
