Will Neil take back what he said about Pluto? Neil deGrasse Tyson and comedian Chuck Nice explore planets, dwarf planets, and the Kuiper belt with planetary scientist and principal investigator for the New Horizons Mission, Alan Stern. NOTE: StarTalk+ Patrons can listen to this entire episode commercial-free here: https://startalkmedia.com/show/debating-plutos-planethood-with-alan-stern/Thanks to our Patrons laura, Mihajlo Jovanovic, Heather Smith, Juan Ignacio Galán, Artsaveslife, Frank Wagner, Adam Brown, Greg Albrecht, Mickey Fuson, and Jeremy Green for supporting us this week.
For decades, all the planets of the solar system had been reconnoitered—except Pluto. That last planetary body had been seen, at best, as just a faint smudge by the Hubble Space Telescope. Then, in 2015, the New Horizons spacecraft sped by Pluto, sending back a swath of exciting images and science data, transforming our view of the planet. It subsequently visited the Kuiper Belt object Arrakoth and may rendezvous with another, more distant body—or not. NASA's new budget seems to spell the end of active science for New Horizons, something that does not sit well with the program's Principal Investigator, Dr. Alan Stern. Join Alan as he speaks with us about this very exciting project and what it may take to keep it alive.

Folge 14 startet mal wieder mit zwei aktuellen Themen, die aber leider beide unerfreulich sind: Russland hat die Zusammenarbeit auf der ISS beendet & die Schauspielerin Grace Dell „Nichelle“ Nichols ist am 30. Juli gestorben. Sie war vor allem für ihre Rolle als Lieutenant Uhura in Star Trek bekannt („Hailing Frequencies Open“). Lynn Margulis war Biologin & hat zu Lebzeiten vor allem kontroverse Theorien vertreten. Wofür man sie allerdings kennen sollte, ist die Weiterentwicklung Endosymbiontentheorie. Zum Thema Pluto stellt Juni heute sogar zwei Wissenschaftlerinnen vor: Alice Bowman leitet die New Horizons Mission zum Pluto und darüber hinaus ins Universum. Die Daten, die 2015 über Pluto gesammelt wurden, werden seit 2016 ausgearbeitet. Daran ist unter anderem auch Kelsi Singer beteiligt, sie ist Planetologin. Nun gab es auf Pluto zwei ungewöhnlich Entdeckungen, bei deren Schlussfolgerung sich die Frage stellt, ob es Leben auf Pluto geben kann… PS: an dem Duzen arbeiten wir (Philipp) noch ;) Doku Terra X Pluto (nur noch bis zum 31.08. verfügbar) https://www.zdf.de/dokumentation/zdfinfo-doku/zwergplanet-pluto-entdeckung-einer-fernen-welt-100.html Richard Dwarkins „It works… bitches“ https://m.youtube.com/watch?v=n6hxo1sC-dU Intro/Outro-Music: A Few Moments Later by Shane Ivers - https://www.silvermansound.com Episodenbilder: https://de.wikipedia.org/wiki/Lynn_Margulis#/media/Datei:Lynn_Margulis.jpg, Self-published work by Jpedreira, CC BY-SA 2.5 https://www.flickr.com/photos/nasahqphoto/46506443632, NASA/Joel Kowsky https://thebridge.agu.org/files/2019/08/Pluto_Kelsi-Singer.jpg, Photo by Rayna M Tedford/WUSTL Photos
Where Are The Black Physicists? Black scientists make up less than one percent of physics PhDs in the U.S. And since 1999, most physics departments in the country have failed to graduate more than one or two Black undergraduates. Furthermore, the share of Black students in physics is declining: If the number receiving a bachelor's degree in physics had kept pace with the rising popularity of the major, there would be 350 Black physicists graduating every year. Instead, in 2020, that number was 262. But why is this number so small? A comprehensive investigative series in Science Magazine this week examines those statistics, the academic climate of physics departments, and how academia may be limiting the achievement of Black students. The series also highlights some success stories about proposed solutions, with mixed results. But why is physics a uniquely white, male discipline—and how can institutions make the climate more friendly to students from marginalized backgrounds? Ira talks to Apriel Hodari, one of 150 Black women to receive a PhD in physics in the U.S., who now researches the culture of higher education in STEM fields. Why The Equinox Can Make Your Credit Card Fail Twice a year, people listening to signals from satellites in geostationary orbit face a problem known as a solar outage, a solar transit, or sun fade. Around the spring equinox, the Sun approaches the equator from the south, as the north gets ready for spring. In the fall, near the autumnal equinox, the Sun appears to move back below the equator. During these times, it comes into the view of Earthbound satellite dishes directed at geostationary satellites positioned some 22,000 miles above the equator. When a ground receiver, the satellite it's looking at, and the Sun all line up, the radiation from the Sun can temporarily overwhelm the satellite receiver. Think of it like when you're driving on a westbound road close to sunset, and you're staring straight into the setting sun—it gets hard to read the road signs. The effect is temporary: a maximum of 12 minutes at any given location for several days in a row. But it can affect everything from a satellite TV dish to credit card processing at your local gas station—even public radio stations receiving live programming over the satellite network. SciFri's Charles Bergquist talks with Chris DeBoy, who teaches a course in satellite communications at the Johns Hopkins University (and is also the RF communications lead for the New Horizons Mission to Pluto, and the Space Engineering Branch Manager at the Johns Hopkins Applied Physics Laboratory), about the advantages and disadvantages of geostationary satellites, and what can be done to minimize the impact of solar outages. They are joined by MaryJane Peters, technical operations chief at KAZU in Monterey, California, who describes the effect the seasonal outages have on station operations. Can Meteorites On Earth Point To Ancient Life On Mars? In 1996, the late astrobiologist David McKay and his team published a paper arguing that a four-pound rock from Mars, called Allan Hills 84001 (found in Antarctica), showed evidence of ancient microbial life on the planet Mars. The team pointed to several mineral structures, including tiny beads of magnetite, as well as shapes that might be fossilized bacteria. This hypothesis ignited a storm of controversy and a flurry of research that contradicted the team's theory. But decades later, ALH 84001, like the other meteorites that have been linked to the Red Planet, remains an important insight into Martian geology and the formation of organic molecules in the absence of biological processes. Producer Christie Taylor talks to astrobiologist Andrew Steele, who has been studying ALH 84001 and other meteorites for decades. He discusses the process of probing meteorites for data, the difficulty of studying rocks without their original contexts, and how new samples from the Perseverance rover could change everything. Plus, how the original controversy over ALH 84001 changed the trajectory of planetary science. From Zero To 100 Butts: The Wild World Of Invertebrate Behinds Recently, the staff of Science Friday came across a tweet that caught our attention, sent out by researcher Dr. Maureen Berg. Turns out, it was a call to source comic ideas for Invertebrate Butt Week, a celebration of—you guessed it—the butts of invertebrates. “Invertebrates really get the short end of the stick,” says Rosemary Mosco, the creator of the comic series Bird And Moon and #InverteButtWeek organizer. “People are not as excited about them as, say, a majestic whale or a beautiful bird. And I love my birds, but [invertebrates have] such an incredible diversity. So, butts are sort of a cheeky way to access some of that amazing diversity and celebrate it.” Rosemary and other scientists and illustrators teamed up to create #InverteButtWeek, a celebration of the behinds of the backbone-less. “It's a chance for some people who do science communication to do the silliest thing that they can possibly think of,” says Dr. Ainsley Seago, curator of invertebrate zoology at the Carnegie Museum of Natural History. Science Friday's Daniel Peterschmidt talks to the organizers of #InverteButtWeek about how it came together, their favorite invertebrate butt facts (like how sea cucumbers have anal teeth), and how you can participate in the celebration.

This week we are excited to welcome Dr. Alan Stern, Principal Investigator from the New Horizons Mission, back to the WSH. In October, it was announced that Alan will be the first NASA-funded commercial space crewmember aboard a Virgin Galactic suborbital space mission. The flight is expected to take place in 2022; there he will perform astronomical and space physiology experiments. Alan is a planetary scientist, space program executive, aerospace consultant, and author. He leads NASA's New Horizons mission to the Pluto system and the Kuiper Belt. In both 2007 and 2016, he was named to the Time 100. In 2007, he was appointed NASA's chief of all science missions. Since 2009, he has been an Associate Vice President and Special Assistant to the President at the Southwest Research Institute. Additionally, from 2008-2012 he served on the board of directors of the Challenger Center for Space Science Education, and as the Chief Scientist and Mission Architect for Moon Express from 2010-2013. From 2011- 2013, he served as the Director of the Florida Space Institute. Alan's career has taken him to numerous astronomical observatories, to the South Pole, and to the upper atmosphere aboard various high performance NASA aircraft including F/A-18 Hornets, F-104 Starfighters, KC-135 Zero-G, and WB-57 Canberras. He has been involved as a researcher in 24 suborbital, orbital, and planetary space missions, including 9 for which he was the mission principle investigator; and he has led the development of 8 scientific instruments for NASA space missions. In 1995, he was selected as a space shuttle mission specialist finalist, and in 1996 he was a candidate space shuttle payload specialist. In 2010, he became a suborbital payload specialist trainee, and is expected to fly several space missions aboard XCOR and Virgin Galactic vehicles in 2016-2017. Before receiving his doctorate from the University of Colorado in 1989, Alan completed twin master's degrees in aerospace engineering and atmospheric sciences (1980 and 1981), and then spent six years as an aerospace systems engineer, concentrating on spacecraft and payload systems at the NASA Johnson Space Center, Martin Marietta Aerospace, and the Laboratory for Atmospheric and Space Physics at the University of Colorado. His two undergraduate degrees are in physics and astronomy from the University of Texas (1978 and 1980). His academic research has focused on studies of our solar system's Kuiper Belt and Oort cloud, comets, the satellites of the outer planets, the Pluto system, and the search for evidence of solar systems around other stars. He has also worked on spacecraft rendezvous theory, terrestrial polar mesospheric clouds, galactic astrophysics, and studies of tenuous satellite atmospheres, including the atmosphere of the moon. Alan is a fellow of the AAAS, the Royal Astronomical Society, and is a member of the AIAA, AAS, IAF, and the AGU; he was elected incoming chair of the Division of Planetary Sciences in 2006.

Why Pluto Matters, According to the Scientist Who Got Us Closest to the Dwarf Planet (0:30)Guest: Alan Stern, Principal Investigator, New Horizons Mission, NASAThe solar system you learned in grade school got a major shakeup in the late 1990s. Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune are all still there. But Pluto was always the odd planet out. So distant and small and not like the little rocky planets near the sun or gas giants, either. But then, high-powered telescopes revealed in the 1990s that tiny Pluto was just one of a whole class of dwarf planets way out there that far outnumber the planets we all memorized in school. So NASA said, “We gotta go explore that place.” And planetary scientist Alan Stern said, “I'm your man.” 737 Max Crisis Fuels Major Losses for Boeing in 2019 (21:18)Guest: Scott Hamilton, Managing Director of the Leeham CompanyBoeing said today it lost half a billion dollars in 2019 –that's the first annual loss for the company in more than two decades and there's one reason for it: the 737 Max. Should We Be Scared of Facial Recognition Technology? (35:39)Guest: Eric Goldman, Law Professor, Santa Clara UniversityA privacy advocacy group and 40 other organizations wrote a letter to the government this week, calling for a ban on facial recognition technology. The letter was prompted by a recent New York Times expose on a company called Clearview AI. It's all really speculative right now, but the article claims that Clearview is pulling images from social media sites to create a facial recognition program and that more than 600 law enforcement agencies have used it to solve crimes. The Apple Seed (50:39)Guest: Sam Payne, Host, The Apple Seed, BYUradioSam tells the story of how the Grammys came to be and some of the surprise winners of those first awards. Jane Austen's Unfinished Novel Hits The Small Screen (58:44)Guest: Jane Hinckley, Professor of Comparative Arts & Letters, Brigham Young UniversityWhen Jane Austen died of illness at the age of 41, she was working on another novel, but she only finished 11 chapters. It's got an unusual setting for an Austen story and it features her only black character. What did she have in mind for this novel? A writer known for adapting Jane Austen for film and television has taken a stab at finishing it for a series airing now on PBS Masterpiece. It's called Sanditon. Lost and Found: Young Fathers in a New Age (1:20:31)Guest: Paul Florsheim, PhD, "Coauthor of Lost and Found: Young Fathers In the Age of Unwed Parenthood," Professor of Community and Behavioral Health Promotion, University of WisconsinThe rate of teenage pregnancy in America has declined drastically over the last 20 years –which is good news. But over that same period, we've seen a steady rise in unwed parenthood –especially among young parents under the age of 25, and the kids end up being raised by a very young –often very poor-single mother. What about the young fathers? What could help them be more involved in the lives of their children?
Episode 24: Spaced Out – In this episode we speak with Alice Bowman, Johns Hopkins Applied Physics Lab Mission Operations Manager for NASA’s unprecedented New Horizons Mission, to Pluto and the Kuiper Belt. We also talk to Jonathon Roth author of BEEP & BOB, a the children’s book series set in outer space, and Courtney Gardinier, Teen Instructor and Research Specialist for HCLS who is literally bringing outer space down to earth.

This week on we're turning our attention to Pluto – what we used to think of as our ninth planet – and also to the mysterious new Planet 9 that might be orbiting on the outskirts of our solar system. We speak to Jeffery Moore, a research scientist at the NASA Ames Research Center, about what we've learned so far about Pluto from the New Horizons Mission. And we speak with Mike Brown, Professor of Planetary Astronomy at Caltech, about the search for Planet 9, and why we think there's another large planet out there revolving around our sun.
