#018: Searching for Asteroid Threats and Space Junk - Dr. Vishnu Reddy

04/07/21 • 64 min

Today we are joined by Dr. Vishnu Reddy. Dr. Reddy is an Associate Professor of Planetary Sciences at the Lunar and Planetary Laboratory at the University of Arizona. Prior to serving as faculty, Vishnu was a research scientist at the Planetary Science Institute in Tucson. He is a co-investigator of NASA's Near Earth Camera Mission to discover 90% of Near Earth Objects larger than 140M. In addition to his work with NASA, Vishnu is part of the space- situational awareness program at UArizona where he has developed a network of small optical sensors to characterize orbital debris and active resident space objects for the US Air Force Research Laboratory. Dr. Reddy’s research focuses on understanding the behavior of space objects (both natural and artificial) using a range of Earth and space-based assets. In this episode, Dr. Reddy shares his amazing and unorthodox journey of becoming a planetary scientist. We discuss in-depth the threats that near earth objects like asteroids and comets pose to our society, and revisit catastrophic and regional impact events from the past. Dr. Reddy discusses his current research and the changes in congressional support for asteroid research in more recent years. Vishnu's passion for planetary science and teaching is palpable, and I hope you enjoy this episode.

#017: Chasing Ice, Coral, and the Social Dilemma - Director Jeff Orlowski

Jeff Orlowski is the director, producer, and cinematographer of the award-winning films Chasing Coral and Chasing Ice. Chasing Coral received the US Documentary Audience Award at Sundance in 2017. Chasing Ice received the Documentary Cinematography award at Sundance in 2012 and was nominated for an Academy Award for Best Original Song. Both films were shortlisted for an Academy Award for Best Documentary, screened at Congress and the United Nations, and have garnered awards and accolades from film festivals around the globe. Jeff founded Exposure Labs, a production company dedicated to impact through film. His latest film, The Social Dilemma, had its world premiere at the 2020 Sundance Film Festival. In this episode, Jeff takes us through his rich journey as a filmmaker, negotiator, and a change-maker. He sheds light on the challenges and triumphs of documenting massive and often invisible, global environmental and social challenges unfolding in our world today. www.exposurelabs.com https://www.chasingcoral.com/ https://www.thesocialdilemma.com/

#019: Coral Reefs Through Time - Dr. Stuart Sandin

In this episode we are joined by Dr. Stuart Sandin. Stuart is the Oliver Chair in Marine Biodiversity and Conservation at Scripps Institution of Oceanography, UC San Diego. He is a professor in the Marine Biology Research Division, and he serves as director of the Center for Marine Biodiversity and Conservation. Sandin has coordinated multiple ship- and land-based expeditions to the remote islands of the central and south Pacific Ocean, with much work conducted in the Line Islands archipelago. He has been using this island gradient and others to study the individual and interacting roles that local human activities and oceanographic context play in the fisheries dynamics and general functioning of coral reef ecosystems. The work in the Pacific has led to the development of the 100 Island Challenge research campaign. In this episode, Stuart and I discuss what Caribbean reefs used to look like and why they've changed. Further, we explore how Stuarts Lab is using structure from motion technology to map out reefs systems over time. We broach the topics of self organization, resilience, evolutionary succession, and technology driven ecological research.
