Miles To Go

In this wide-ranging conversation, astronaut Leroy Chiao joins Miles to talk candidly about what it’s really like to live and work in space — and inside NASA. From Cold War suspicion to Russian cooperation, and from toilet paper certification to Starliner delays, it’s a journey full of humor, frustration, and hard-earned insight. Chiao also shares why he almost flew a year-long mission (spoiler: a very large space tourist), what happens when blood flows the wrong way in microgravity, and whether Jared Isaacman can actually fix what’s broken at NASA.

In this special edition of Miles to Go, I sit down with longtime friend and aviation expert Lars Perkins to analyze the NTSB’s latest findings on the midair collision over the Potomac River. We discuss the altimeter discrepancy, the challenges of visual flight rules (VFR), and whether night vision goggles (NVGs) may have hindered rather than helped the helicopter crew. We also explore systemic issues in aviation safety, including the normalization of deviance—where repeated near misses create a false sense of security. Finally, we examine the political interference in the NTSB investigation and what the agency’s next steps might reveal.

A tragic mid-air collision near Washington Reagan Airport has put a spotlight on the dangers of D.C.'s complex airspace. In this episode, veteran pilot Harold Coghlan joins Miles O’Brien to break down what happened, the risks of military and civilian aviation operating so closely, and what needs to change to prevent future disasters.

This episode of Miles To Go features Jared Isaacman, serial entrepreneur, space explorer, and nominee for NASA Administrator. From founding Shift4 Payments to commanding groundbreaking space missions like Inspiration4 and Polaris Dawn, Isaacman shares his extraordinary journey. We discuss his aviation roots, his leadership style, and the challenges and opportunities ahead as he prepares to lead NASA. A must-listen for anyone curious about the future of space exploration.

In this conversation, Miles O'Brien and J. Alex Halderman discuss the critical issues surrounding election security, focusing on the importance of trust, the vulnerabilities of local voting systems, and the impact of cybersecurity threats. They explore the implications of razor-thin margins in elections, the challenges of public discourse on election integrity, and the political dynamics that influence election security legislation. The discussion also touches on the effects of bomb threats on voter turnout, the need for better auditing processes, and the future of election technology, including the potential vulnerabilities introduced by systems like Starlink.

In this episode of Miles to Go, we delve into the invisible world of methane leaks with environmental advocate Melissa Ostroff. Armed with a thermal imaging camera, Melissa tracks methane emissions from century-old oil wells in Pennsylvania's Allegheny National Forest to the streets of Philadelphia. Methane, a powerful greenhouse gas, is responsible for 30% of global warming, yet it often escapes detection due to insufficient monitoring and outdated infrastructure. Join Miles O'Brien as he follows Melissa's journey, uncovering the surprising scale of methane leaks—from abandoned wells to her own basement. This eye-opening discussion reveals the hidden dangers of our reliance on natural gas and highlights the urgent need for better policies and technologies to address these emissions. Don't miss this compelling exploration of a problem hiding in plain sight.

Today is Election Day—at long last. I am exhausted, and I suspect many of you feel the same way. I am in Georgia to cover this important day in history for the PBS News Hour. I'm sure you know by now Georgia is one of the seven swing States where the actual decision will be made on who is our next president. Despite no evidence to support the notion, Donald Trump and his allies have repeatedly questioned the Integrity of the vote tallying process in this country.  Georgia became one of the main targets of these so-called election deniers in the wake of the 2020 election. But long before the likes of Mike Lindell and Sidney Powell descended on places like Coffee County to try and steal the presidency from Joe Biden, Donna Curling was raising questions about the security and integrity of the machines that Georgia uses to record and tabulate votes. The lawsuit, now called “Curling v. Rafensperger,” began when Donna had just moved to Georgia and voted on machines made by Diebold, which left no verifiable paper tr

In this three part miniseries, Miles O'Brien and Lars Perkins - along with several special guests - investigate the bizarre circumstances that led to one of the most fatal plane crashes of all time. This is the story of Japan Air Lines Flight 123.

Miles to Go returns after a long hiatus. In this “black box” special, Miles O’Brien talks with two pilots to try and understand why the 737 plummeted to the ground so suddenly and precipitously. Was it deliberate?

Marvin Minsky is often regarded as the father of modern AI, but when Miles visited him in 2010, Minsky wasn’t a proud father. In fact, Minsky was disappointed with the lack of progress in the field and had reservations about its future. Unfortunately, Minsky is no longer with us and can’t answer our questions about machine learning and new robots, but his answers from this interview in many ways still hold. Go back in time on this episode of Miles To Go.

How did our early solar system form? What are the origins of life? How likely are we to get hit by a dangerous asteroid? A daring NASA mission called OSIRIS-REx hopes to find the answers to these big questions at an asteroid named Bennu. This week, the spacecraft arrives at its destination. To learn more, Miles sits down with members of the OSIRIS-REx team on this episode of Miles To Go.

Jupiter has many moons, but none are quite like Europa: it has a thick crust of ice and a huge amount of liquid saltwater underneath its surface. In fact, many believe it’s the best place in the Solar System that we could find other lifeforms. To dive deeper into the mysteries of this icy world–and how we plan on exploring it–Miles sits down with Kevin Peter Hand, Deputy Project Scientist of NASA’s Europa Mission on this episode of Miles To Go.

Hurricane Florence was a perfect example of how climate change supercharges extreme weather events. But climate change also affects us in other more subtle, interconnected, and difficult to manage ways. Thankfully, people like June Blotnick, Executive Director of environmental advocacy group Clean Air Carolina, are working on the ground to help communities battle climate change. Miles sits down with June to learn more about how the average citizen can move the needle on these issues.

Steve Squyres is the principal investigator for the Mars Exploration Rover Program, which gave us the plucky and productive rovers Spirit and Opportunity. With the latter on life support and the former no longer with us, I spoke with him about his amazing run on Mars and what he’s working on now. It’s all out-of-this-world stuff.

There are calls in the EPA and in Congress for the use of more transparent science. But what does that mean? Why do scientists seem united against these regulations? And what would it mean if they went into effect? In this special Hash it Out episode, Brian and Fedor talk to vocal opponent of science transparency regulations George D. Thurston, Director of the Program in Exposure Assessment and Human Health Effects at the Department of Environmental Medicine, NYU School of Medicine.

For more than three decades, behavioral biologist Denise Herzing has tracked and observed a pod of wild spotted dolphins that live in the warm clear waters of the Bahamas. She’s learned an awful lot about their behaviors and their communication–or is it a language? Denise has as good a chance as anyone to find out what the dolphins might be saying to each other. But the question is: if we could communicate with them, what would we say? Maybe we should start with an apology.

Methane is a Dr. Jekyll and Mr. Hyde kind of gas: on one hand, it is the cleanest-burning fossil fuel. On the other, if it leaks, methane itself is a much more potent greenhouse gas than carbon dioxide. In this special Hash It Out episode, Brian and Fedor go from 18th century Italian methane guns to present day Google Street View cars that sniff out methane leaks. Listen to learn about the history of methane, its current uses, and what is being done to curb its environmental impact.

For several years, environmental advocacy groups have been fighting to ban the pesticide chlorpyrifos from agricultural use. A turnover in leadership at the EPA has led to a moment of indecision on what to do about the chemical. Robert Sapolsky is a neuroscientist who’s spent a long time assisting in the legal battle against chlorpyrifos. We discussed the devastating effects of chlorpyrifos on an exposed nervous system as well as his work to discredit the industry science claiming its safety.
