In 1908, on a sunny, clear, quiet morning in Siberia, witnesses recall seeing a blinding light streak across the sky, and then... the earth shook, a forest was flattened, fish were thrown from streams, and roofs were blown off houses. The “Tunguska event,” as it came to be known, was one of the largest extraterrestrial impact events in Earth’s history. But what kind of impact—what exactly struck the earth in the middle of Siberia?—is still up for debate. Producer Annie McEwen dives into one idea that suggests a culprit so mysterious, so powerful, so... tiny, you won’t believe your ears. And stranger still, it may be in you right now. Or, according to Senior Correspondent Molly Webster, it could be You.EPISODE CREDITS Reported by - Annie McEwen and Molly WebsterProduced by - Annie McEwen and Becca Bresslerwith help from - Matt KieltyOriginal music and sound design contributed by - Jeremy Bloom, Annie McEwen, Matt KieltyMixing by - Jeremy Bloomwith dialogue mixing by - Arianne WackFact-checking by - Diane Kellyand edited by - Alex Neason

The Right Stuff

Since the beginning of the space program, we’ve expected astronauts to be fully-abled athletic overachievers—one-part science geeks, two-part triathletes—a mix the writer Tom Wolfe called “the right stuff.”

But what if, this whole time, we’ve had it wrong?

In this episode from 2022, reporter Andrew Leland joins blind Linguistics Professor Sheri Wells-Jensen and a crew of 11 other disabled people. They embark on a mission to prove not just that they have what it takes to go to space, but that disability gives them an edge. On Mission AstroAccess, the crew members hop on an airplane to take a zero-gravity flight—the same NASA uses to train astronauts. With them, we learn that the challenges to making space accessible may not be the ones we thought. And Andrew, who is legally blind, confronts unexpected conclusions of his own.

By the way, Andrew’s new book is out. In The Country of the Blind: A Memoir at the End of Sight (https://zpr.io/nLZ8H), Andrew recounts his transition from sighted to blind. Suspended between anxiety and anticipation, he also begins to explore the many facets of blindness as a culture. It’s well worth a read.

Read the article by Sheri Wells-Jensen, published in The Scientific American in 2018. “The Case for Disabled Astronaut” (https://zpr.io/nLZ8H).

This episode was reported by Andrew Leland and produced by María Paz Gutiérrez, Matt Kielty and Pat Walters. Jeremy Bloom contributed music and sound design. Production sound recording by Dan McCoy. Special thanks to William Pomerantz, Sheyna Gifford, Jim Vanderploeg, Tim Bailey, and Bill Barry

Right to be Forgotten

In online news, stories live forever. The tipsy photograph of you at the college football game? It’s there. That news article about the political rally you were marching at? It’s there. A charge for driving under the influence? That’s there, too. But what if... it wasn’t?

Several years ago a group of journalists in Cleveland, Ohio, tried an experiment that had the potential to turn things upside down: they started unpublishing content they’d already published. Photographs, names, entire articles. Every month or so, they met to decide what content stayed, and what content went. In this episode from 2019, Senior Correspondent Molly Webster takes us inside the room where the editors decided who, or what, got to be deleted. And we talk about how the “right to be forgotten” has spread and grown in the years since. It’s a story about time and memory, mistakes and second chances, and society as we know it.
