Welch eine Zerstörung auch ein vergleichsweise kleiner Asteroid anrichten kann, hat sich zuletzt 2013 angedeutet, als ein Meteor über Tscheljabinsk niederging. Obwohl der nur etwa 20 Meter groß war, beschädigte er jede Menge Gebäude in der russischen Stadt, weit über 1000 Menschen wurden verletzt. Dies ist nun schon acht Jahre her. Inzwischen sind wir zwar schon ein bisschen besser vorbereitet, aber immer noch nicht auf alles. Das zeigt das jüngste Planspiel zur planetaren Verteidigung, das vergangene Woche im Rahmen der Planetary Defense Conference stattfand. Zwar kam der fiktive Himmelskörper in der Übung nicht ganz so aus dem Nichts wie der aus Tscheljabinsk, aber die sechs Monate Vorlaufzeit reichten in dem Szenario trotzdem nicht für mehr als eine rechtzeitige Evakuierung. Was die Übenden dabei gelernt haben und wie es um die planetare Verteidigungsfähigkeit steht, besprechen wir mit Detlef Koschny, dem Chef des Planetary Defence Office der Europäischen Weltraumagentur ESA. Wie genau muss man sich solch eine Übung vorstellen, wer nimmt alles teil? Wie realistisch sind die durchgespielten Szenarien, wie groß ist die Gefahr eines Asteroideneinschlags? Die meisten richtig großen Asteroiden kennen wir, aber wo tappen wir noch im Dunkeln? Welche Pläne gibt es, Gefahren früher zu erkennen? Wie gut (oder schlecht) sind wir wirklich vorbereitet und bei welcher Vorwarnzeit könnte Gegenmaßnahmen auch im All eingeleitet werden? Was hat sich seit dem Einschlag von Tscheljabinsk getan? Wie gut funktioniert die internationale Koordination? Was macht das Planetary Defense Office? Darüber und über viele weitere Fragen auch aus dem Publikum sprechen Kristina Beer (@bee_k_bee) und Martin Holland (@fingolas) von heise online live mit Dieter Koschny, dem Chef des Planetary Defence Office der ESA.

Once every two years, asteroid experts around the globe meet up and pretend an asteroid impact is imminent. Why? To prepare for the likely – but plausible – scenario in which this comes true. In this episode, we speak about the hypothetical impact scenario playing out at this year's Planetary Defense Conference and why it matters, with Detlef Koschny, ESA's Head of Planetary Defence.

NASA Practicing Techniques for Countering Deadly Asteroids (0:40)Guest: Richard Binzel, PhD, Professor of Planetary Science, MITIn early August, NASA put out a startling press release announcing that an asteroid the size of a football field had just barely missed colliding with Earth. All of NASA's monitoring systems had failed to notice the asteroid was coming. If it had hit us, it would have obliterated everything within 50 miles of the impact, says NASA. Coincidentally, NASA held a Planetary Defense Conference a few months earlier to plan for just that kind of scenario. They ran a simulation in which scientists launched six imaginary spacecraft at the imaginary asteroid, hoping to knock it off course. But instead, a chunk split off the asteroid and ended up destroying half of Manhattan. MIT planetary scientist Richard Binzel participated in the practice run of NASA's plan to protect us from an asteroid strike.

Author of “Making Tough Decisions about End-of-Life Care in Dementia”Dementia diagnoses hit 500,000 Americans a year –but that number is only the beginning. There are usually several family members who suffer alongside the dementia patient, and it is no easy task for them to get through the experience with their sanity and relationships intact. Anyone embarking on that journey could use a guide. (Originally aired November 21, 2018) Training Robots Just Like We Train (39:29)Guest: Matthew E. Taylor, assistant professor of Electrical Engineering and Computer Science, Washington State UniversityIn the not-too-distant future, when robots are cooking our meals and cleaning our houses, how do you suppose we'll train them to do things the way we like them? To add that extra dash of spices right at the end? Or tuck the bed sheet corners in the way we like them? Goodness knows I've struggled to get my smart phone set up just the way I like it. . . I can only imagine what challenge a robot maid might present. This is the riddle Matthew Taylor is tackling at Washington State University's School of Electrical Engineering and Computer Science, where he's a professor. He thinks maybe training a robot will be similar to training a dog. (Originally aired June 21, 2016) Are 16-year-olds Mature Enough to Vote? (51:10)Guest: Takoma Park Mayor Kate Stewart & Former Takoma Park Youth Council Chairperson Kiran Kochar McCabeMany of the young activists who've been joining immigration and climate protests over the last few years will still be too young to vote come the 2020 election. The national voting age is 18. But states can let younger people vote in statewide elections. City governments can do the same thing for citywide elections. Takoma Park, Maryland, which is a suburb of Washington, DC, six years ago became the first city to lower its local election voting age to 16, despite concerns that kids that young aren't mature enough to cast an informed vote. (Originally aired August 13, 2018) New DNA Sequencing Technique Diagnoses Diseases Better (1:10:59)Guest: Charles Chiu, MD, Professor of Laboratory Medicine and Infectious Diseases at the University of California at San FranciscoThere's a fair amount of guesswork and trial-and-error in treating a patient with a mysterious infectious disease. Even when you've got what looks like a common cold or flu virus, a test can take days to come back with enough specifics to guide your doctor on which medicine to prescribe. In critically ill patients, where the infection is moving fast and time is short, doctors need better options. (Originally aired July 8, 2019) The Forgotten Homeless (1:25:31)Guest: Graham Pruss, Researcher, University of Washington's Interdisciplinary Critical Narratives Team and Homeless Research InitiativeBig cities with expensive housing across the country are seeing a rise in the number of people living in their cars. Oakland, California this week announced its car and RV dwelling population has doubled over the past two years. This is a tough population for cities to help because, technically car campers are homeless, but they don't usually consider themselves homeless and they're not interested in staying at a homeless shelter or accessing homeless services. So they fall through the cracks –and become a nuisance for neighborhoods who don't want overstuffed cars parked perpetually on their streets. (Originally aired July 25, 2019)

On April 13, 2029, a 370-meter wide asteroid formally known as 99942 Apophis will pass by Earth at a distance of about 19,000 miles. While 19,000 miles sounds like a long way away, but in astronomical terms it's the equivalent of having a bullet whiz by your ear. There are man-made satellites that orbit farther from Earth. Even scarier, it was initially believed there was a slight chance Apophis could strike the Earth in 2036. That's why, when the asteroid and its trajectory was discovered in 2004, scientists named it after the Egyptian god of chaos who, by the way, is also the villain in the TV series, Stargate-SG1. Thankfully, that possibility has since been ruled out. Still, as the saying goes “There are plenty more where that came from,” in particular, in the asteroid belt between Mars and Jupiter. The imminent threat of asteroid-caused destruction was the motivation behind a recent Planetary Defense Conference at NASA's Goddard Space Flight Center. The purpose of the conference was to discuss “the threat to Earth posed by asteroids and comets, and actions that might be taken to deflect a threatening object.” While the chances of something the size of Apophis or bigger hitting the Earth are remote, it would only take one to dramatically alter or even destroy human civilization as we know it. Thus, we should be grateful that scientists are taking the potential threat seriously. And yet, all of this underscores how improbable our very existence, never mind human civilization, is. There is something called the “Rare Earth Hypothesis,” which holds that intelligent life is the result of “improbable astrophysical and geological events and circumstances.” Whereas people like Carl Sagan insisted, based on faulty math and even faultier logic, that intelligent life was common in the Cosmos, the Rare Earth Hypothesis takes note of all the things that had to go exactly right for us to exist. For instance, not only does a planet have to be just the right distance from its sun, often called the “Goldilocks Zone,” but its tilt and orbit must be just right, too. And, its sun must also be just the right distance from the center of its galaxy. Even if the astrophysical requirements are met, there's still geology. The historian Will Durant once wrote that “civilization exists at the forbearance of geology, subject to change without notice.” For a stark reminder of how precarious human life and civilization are geologically, just recall the 2004 earthquake and tsunami off the coast of Sumatra that killed more than 200,000 people. As horrific as that geological event was, it wasn't even the deadliest of my lifetime: In 1976, an earthquake in China killed between 240 and 600 thousand people. Our response to our persistent existence despite the precariousness of our condition shouldn't be fear or alarm; it should be wonder and gratitude that we are here at all. Think of Psalm 8, where considering the moon and stars prompts the question “What is man that you are mindful of him, the son of man that you care for him?” Compared to much of the created order, never mind God, we're fragile, dependent, and not very powerful. Nevertheless, God is mindful of us and He does care for us. In the climax to the book of Job, the Lord, speaking out of the whirlwind—yet another natural phenomenon we are powerless against—makes it clear that He is not obligated to speak to us. He is the creator. We are the creatures. And yet, He does speak to us. Even more than that, he became one of us. He took on our fragility, finitude, and vulnerability. Physicist Freeman Dyson once wrote that the more he examined the universe and the details of its architecture, the more evidence he found that the universe in some sense must have known we were coming. Actually, its creator did, which is why we continue to beat the odds.
