The content below is from Episode 88 of the Who’d a Thunk It? Podcast.

RECOMMENDATION SEGMENT

Netflix & Mark Millar Unveil Slate Of Super Crooks Debut, New Spy Series,  Prodigy Scribes + More – Deadline
  • Netflix has a new series out called Super Crooks. It is based on the popular graphic novel of the same name written by legendary Scottish comic writer Mark Millar and illustrated by Filipino artist Leinil Francis Yu.
    • The story follows a band of super powered people who chose to use their powers for heists instead of being heroes. The try to steal jewels and super powered artifacts while battling the Union of Justice (which are basically the knock off Justice League).
    • This story is definitely meant for adults and not kids as there is plenty of gore, substance abuse, sexual content, and cursing lol.
    • Out on Netflix now so check that out.

NOW FOR THE MAIN EVENT

  • As you are about to find out: I am a total freaking nerd for astronomical discoveries.
    • Space exploration really tickles all of my fancies. Learning about what is out there in the final frontier of space… it just matters.
    • The older and more mature I become I find that a lot of what I thought mattered as a child doesn’t hold much meaning. But when it comes to exploration. That I think is a major part of what makes us human. We are explorers.
    • That’s why this week’s topic really makes my eyes twinkle with wonder.
    • It is time for humanity to dredge up a few more of the universe’s secrets and put them on display for the world to see!

  • The James Webb Space Telescope (sometimes called JWST or Webb) is a space telescope being jointly developed by NASA, the European Space Agency, and the Canadian Space Agency. It is planned to succeed the Hubble Space Telescope as NASA’s Flagship astrophysics mission.
    • The telescope will be a large infrared telescope with a 6.5-meter primary mirror. The telescope will be launched on an Ariane 5 rocket from French Guiana (South America) in 2021. 
      • The current launch date is set to December 22, 2021 – but as you will see soon, that date is not set in stone.
    • The Webb telescope will be the premier observatory of the next decade, serving thousands of astronomers worldwide. It will study every phase in the history of our Universe, ranging from the first luminous glows after the Big Bang, to the formation of solar systems capable of supporting life on planets like Earth, to the evolution of our own Solar System.
    • The Webb telescope was formerly known as the “Next Generation Space Telescope” (NGST); (which sounds like a Nerdy Star Trek reference to me). it was renamed in September 2002 after a former NASA administrator, James Webb.
    • NASA’s Goddard Space Flight Center in Greenbelt, Maryland, is managing the development effort. The main industrial partner is Northrop Grumman; the Space Telescope Science Institute will operate Webb after launch.
    • Several innovative technologies have been developed for Webb. These include a primary mirror made of 18 separate segments that unfold and adjust to shape after launch. The mirrors are made of ultra-lightweight beryllium. Webb’s biggest feature is a tennis court sized five-layer sunshield that attenuates heat from the Sun more than a million times. The telescope’s four instruments – cameras and spectrometers – have detectors that are able to record extremely faint signals. One instrument (NIRSpec) has programmable microshutters, which enable observation up to 100 objects simultaneously. Webb also has a cryocooler for cooling the mid-infrared detectors of another instrument (MIRI) to a very cold 7 kelvins (minus 447 Fahrenheit) so they can work.
      • Thats right the optimal operating temperature of these mid-infrared detectors is negative 447 degrees Fahrenheit.
  • Cost: 10 billion USD (2016)
    • Why so pricey? well Webb’s stewards believed the telescope could do more than originally envisioned, so they expanded its parameters overtime. As the years passed and the scope of the mission swelled, so did the cost. … Another reason is that Most of the telescope its gold-plated mirrors and scientific instruments. If you google a quick image of the telescope you are sure to see all the pretty gold plating.
    • The massive telescope weighs 14,000 pounds according to arizona.edu
      • the photos do NOT do the size justice. This thing is the size of a tennish court

  • There have been some major development issues
    • NASA’s latest big astronomy mission has been in the works for about 25 years now. When the concept was first proposed in 1996 as the successor to the famed Hubble Space Telescope, scientists estimated it would cost $500 million and fly by 2007. But… we know it didn’t go down that way. As scientists worked on the telescope’s design, the world around them began to change. Astronomers were making exhilarating discoveries about the cosmos, and engineers were inventing the technology needed to study them. 
      • To give you a better idea of just how much our understanding of the universe has changed since this project started:
      • 1992: Astronomers didn’t even know for sure that there were planets outside our solar system until 1992. THINK about that. It seems like that discovery is OLD news, but thats just 30 years ago.
      • 1998: Astronomers discover the expansion of the universe is accelerating
      • 2001: The Hubble Space Telescope detected the presence of sodium in the atmosphere of the exoplanet HD 209458 b.  That was the first Atmosphere of an exoplanet detected
      • 2002: Mars Odyssey mission detects presence of water on Mars. This is one of my favorite discoveries as water is main ingredient for life and we found evidence of it on another planet. HOW COOL!
      • 2003: WMAP mission confirms existence of dark matter and dark energy
      • 2006: IAU introduces new definition of planet – that’s when we lost Pluto as a major planet and it got downgraded to a Dwarf Planet.
      • 2016: Gravitational waves from colliding black holes – The Laser Interferometer Gravitational-wave Observatory (LIGO) in the United States with the Virgo observatory in Europe announced the measurement of gravitational waves from colliding black holes. This was direct confirmation of an important prediction from Einstein’s general theory of relativity, that gravitational disturbances send out ripples in spacetime.
      • 2019: The historic image of the supermassive black hole was captured by the Event Horizon Telescope (EHT) and released in April 2019. The image does not actually show a black hole, which are known for sucking up light, but rather its shadow, a glowing orange ring of ultra-hot gas.
      • So with all those new discoveries, the people behind the Webb project had to keep changing what it was they wanted to observe. They didn’t want their expensive telescope to become obsolete just months after launch, so they kept changing gears so they could get the most out of the James Webb Telescope launch.

  • But growing pains weren’t the only reason for developmental issues. Back in 2018, the Webb Telescope project announced that instead of being launched that year it would probably take until Spring of 2021 (which they didn’t make that deadline either). With this delay the cost grew again. The new total meant that Webb had breached a cap set by Congress in 2011, when lawmakers had begun to worry in earnest about the mission’s ballooning costs. Back in 2018 if Webb wanted to leave Earth, it needed Congress to approve an extra $800 million for the mission.
    • And while I don’t typically approve of how things are funded via tax dollars, I am almost always pro-space exploration. I think we humans will never know all the secrets of the Universe, but striving to do so, just might be one of our greatest purposes.
    • Of course they got the money. Even the stingiest of politicians realizes that once you’ve sunk $8Billion into a project you can’t just simply pull the plug on it. You might as well go all in.
  • What is this thing made of? Why is it so expensive? well…
    • Piggy-backing off the hard work of a paid journalist named Gerri Miller from TreeHugger.com who interviewed an important figure of Webb’s construction I stole a few quotes:
    • “To go to the earliest galaxies, we needed a bigger mirror, and that bigger mirror had to look at a bigger frequency of light,” says astrophysicist Blake Bullock, who is a director at Northrop Grumman Aerospace Systems, the contractor on the project. “It also had to be kept cold — minus 400 degrees Fahrenheit — so it has a sun shield the size of a tennis court that acts as a giant beach umbrella,” she adds. “It’s like SPF 1 million, blocking the sun’s light.”
    • “It is the biggest, most powerful telescope ever to be put in space. There are big telescopes on the ground but nothing of this nature and complexity in space. Hands down, it’s the most powerful thing out there,” Bullock says.
    • “Hubble, when pushed to its maximum, could see galaxies that were teenagers in terms of age. We want to see babies,” Bullock says. “With the Webb, we will be able to see back in time to the earliest objects in the universe for the first time. Also for the first time, we will be able to characterize other planets going around other stars, distant exoplanets, and see if there are oceans, an atmosphere, what chemical elements are there.”
    • “It has the potential to fundamentally rewrite our textbooks because of how dramatically it will increase our view of the cosmos,” Bullock says. “We will be able to get a much better grasp of the universe we live in. Technology-wise, we are already seeing the implications.”
    • “The technology we invented is being used by eye surgeons, so there are tangible benefits. We’re also learning things on the computer level. We’ve made huge advances in understanding deployables — how we take this giant sun shield the size of a tennis court and fold it up.”

I totally pictured Blake Bullock as this scruffy old nerd… but turns out it is this pretty lady.
  • The Webb is the successor to Hubble, and it’s 100 times more powerful.
    • “It has the potential to fundamentally rewrite our textbooks because of how dramatically it will increase our view of the cosmos” … that is the most exciting part of this entire project for me. It is one of the most vague claims made by the Webb project team, but they sure-as-shit can back it up.
    • To give you a bigger picture of how Webb is going to rock the world’s astronomical minds: Let me take a step back and explain just how monumental Hubble has been.
      • From NASA: When the Hubble mission launched in April 1990, it was meant to spend at least 15 years probing the farthest and faintest reaches of the cosmos. Hubble has far exceeded this goal, operating and observing the universe for over 30 years. During its time in orbit, the telescope has taken more than 1.5 million observations, and astronomers have used that data to publish more than 18,000 peer-reviewed scientific publications on a broad range of topics. 
      • With any piece of machinery that’s 30 years old comes some aging parts. No more servicing missions are scheduled to repair or replace equipment on Hubble. However, a dedicated team of engineers and scientists are continuously working to keep Hubble operating for as long as possible.
      • While nearly impossible to provide a comprehensive list of all the scientific contributions Hubble has made so far during its career, the telescope’s observations have contributed to the understanding of the development and growth of galaxies, the presence of black holes in most galaxies, the birth of stars, and the atmospheric composition of planets outside our solar system. Hubble’s explorations have fundamentally changed our perception of the universe and will continue to reveal new insights for many more years.
    • Now let me say again: The Webb is the successor to Hubble, and it’s 100 times more powerful.
Image of Hubble over Earth
Hubble
  • I am ecstatic for this telescope to reach it’s orbit destination.
    • Webb will orbit around the second Lagrange (L2) point, which is about 1 million miles (1.5 million km) away from Earth, and it takes about a month to travel this distance.
    • After reaching its orbit, Webb undergoes science and calibration testing. Then, regular science operations and images will begin to arrive, approximately six months after launch.
    • So if this bad boy does finally launch in late December of 2021, we still won’t get any results until as early as late June 2022.
    • But that 6 month waiting period is nothing compared to the 25 years of development.
      • Like I said. I am ecstatic!!! When these huge discoveries about the cosmos are made I am transported from my day-to-day life and my mind soars among the stars.
      • When we as humans make these discoveries, I feel less like a passenger on Earth, and more like a crewman alongside 7 billion of my fellow crewmates.
      • It truly is a unifying feeling that makes me proud to be human.

Operation Wandering Souls

The content below is from Episode 82 of the Who’d a Thunk It? Podcast

ANNOUNCEMENT

  • Welcome Who’d a Thunkers!
    • You made it back for another Who’d a Thunk It? Fright Fest Episode.
    • This is the 3rd episode of October 2021 where all episodes of this particularly spooky month have topics based on the macabre!
    • I hope you are ready. Strap in!

RECOMMENDATION SEGMENT

-don’t worry… no spoilers here- I really want you to watch this for yourself!

Midnight Mass - Rotten Tomatoes
  • Midnight Mass
    • It hard for me to put in to words just how much I love this limited series.
    • Director and Creator Mike Flanagan knocked it out of the park once again with this 7 episode story. It will take you on a roller coaster ride!
    • The first episode beautifully establishing the run down but still hopeful small island town while listening to Neil Diamond. Then by the end of the series you’ve watched many a very deep and engaging existential monologues and enjoyed some of the most exciting horror scenes to have ever been on a television series.
      • The final scene of the show coupled with the final song was so moving I cried. Which I totally did not expect to do at all, but it calls for it.
    • The setting, soundtrack, writing, and premise were all so well done that I have to say it beats out my now 2nd favorite works of Mike Flanagan’s, that being Season 1 of Haunting of Hill House.
      • That show felt so fresh and engaging it revived my love for the horror genre.
      • And while looking in to Mike Flanagan for this recommendation I found out he directed the Shining sequel movie Dr. Sleep. Shannon and I saw that in theaters and it was a fun film.
      • Bravo Mr. Flanagan. I’m excited to see what you come up with next.
What Makes 'Midnight Mass' One of the Best New Shows of the Year - The  Ringer

NOW FOR THE MAIN EVENT

  • The 2nd Indochina War started in November of 1955 and lasted until April of 1975.
    • The conflict was in Vietnam, Laos, and Cambodia. It was officially fought between North Vietnam and South Vietnam.
    • In March of 1965 President Johnson launched a three-year campaign of sustained bombing of targets in North Vietnam and the Ho Chi Minh Trail in Operation Rolling Thunder. The same month, U.S. Marines landed on beaches near Da Nang, South Vietnam as the first American combat troops to enter Vietnam.
      • I once knew a Vietnam Veteran named Howard. He was a retired marine in his late 60’s and I was 16. I met him at my first ever job renting out rowboats and canoes on a Pennsylvania state park lake, Lake Pinchot.
      • We both made minimum wage. It was my first job and it was Howard’s last.
      • Looking back now I think I took Howard’s company for granted. I’d like to think he is still around somewhere, but the old man smoked like a chimney, drank like a fish, and by his own admission only ever ate steak and potatoes, so chances are Howard met his maker years ago.
      • I know that’s a blunt way to talk about someone, but that is just how Howard was. That’s how he himself talked about life. He was a dirty old man who hit on all the young girls at the lake, girls young enough to be his granddaughter. He never was without his Vietnam Veteran hat. Now that I’m older I realize he was one of the most interesting people I have ever met.
      • I like Howard a lot but it was clear to everyone the man had his demons. He didn’t try to hide them. He spoke very little of his service and I knew better than to ask about it. But what details he did share horrified me.
The True Story Behind an Iconic Vietnam War Photo Was Nearly Erased — Until  Now - The New York Times
  • Back in 2003 The New York Times reporter John Kifner was covering a story surrounding some Vietnam veterans.
      • “Quang Ngai and Quang Nam are provinces in central Vietnam, between the mountains and the sea. Ken Kerney, William Doyle and Rion Causey tell horrific stories about what they saw and did there as soldiers in 1967.
      • The fighting was intense and the results, the former soldiers say, were especially brutal. Villages were bombed, burned and destroyed. As the ground troops swept through, in many cases they gunned down men, women and children, sometimes mutilating bodies — cutting off ears to wear on necklaces.
      • They threw hand grenades into dugout shelters, often killing entire families.
      • Mr. Doyle said he lost count of the people he killed: ”You had to have a strong will to survive. I wanted to live at all costs. That was my primary thing, and I developed it to an instinct.'”
The Vietnam War, Part I: Early Years and Escalation - The Atlantic
  • In the midst of this kind of chaos the US military resorted to many different tactics to combat their enemy. One tactic was psychological. It was called Operation Wandering Souls.
    • The name of the Operation: Wandering Soul came from the Vietnamese holiday of the same name.
    • A WordPress blog called Vietnam Travel & Visas For Indians writes:
      • Also known as the Trung Nguyen, the holiday takes [place] every 15th day of the 7th lunar month in the Buddhist calendar. The Wandering Soul’s Day is basically the Buddhist version of the All Soul’s Day of the Christian religion.
      • According to Vietnamese belief, each person has two souls, the material soul, and spiritual soul. The material soul is known as Via while the spiritual soul is Hon. Once a person dies, his soul will be taken into a tribunal in hell to be judged. After the judgment is rendered, the soul will either go to heaven or hell, depending on how the person behaved while still on Earth.
      • Locals believe those sinful souls can still be saved from hell by the prayers of the living relatives, which is done during the 1st and 15th of every month. During the Wandering Souls, locals believe that this is the best time for the relatives of the deceased to pray and ask forgiveness on behalf of these sinful souls. It is their belief that the gates of hell will be opened during the sunset and the souls would fly towards it hungrily and unclothed. Some souls would head home to their homes and villages, which is why relatives would cook plenty of food and place on their altars.
      • Those whose souls don’t have any home to go to or the ones that have been forsaken by the living would be wandering helplessly into the air of black clouds and over rivers, from one tree to another. Basically, these “wandering souls” are the ones who are in need of prayer the most. This is why locals would place additional altars filled with offerings in some public places.
    • The American Military caught wind of this holiday and sought to exploit it. For decades after the war families searched for missing Vietcong soldiers. It was a common sight to see Vietnamese mothers scouring the jungles for their lost sons. They mourned their loss and worried for their sons’ souls. They hoped to find their lost bones, wash them, and re-burry them as such is their tradition.
    • The US Military estimates that some 300,000 soldiers are still uncounted for.

  • The US used the Wandering Souls holiday by pleading to the Vietnamese north over the radio and by dropping leaflets out of planes that said:
    • “Comrades, demand that the communist party stop its war of aggression in the south so that no more innocent souls have to join the already great number of innocent souls now wandering in this war-torn country of the south.”
  • On February 10th 1970, Vietcong soliders had been hiding deep in the forest of the Hau Niga Province in South Vietnam. When all the sudden a shrill loud noise is heard. It was being blasted from the Chamberlain Fire Support Army Base.
  • The following recording is of a “Wandering Soul.” Its official title is Ghost Tape Number 10.
    • It was created by the US Amry’s 6th Psychological Operations Battalion in cooperation with the US Navy and is meant to sound as if a dead Vietcong soldier is wandering through the Vietnamese jungle at night.
    • The American military used this tactic because they found out the Vietnamese believe the souls of their unburied comrades would wander aimlessly forever in pain and suffering.
    • At first you will briefly hear musical tones. This is supposed to be music from a Buddhist funeral. And then the soldier speaks…
  • The dialogue heard in the recording was first the voice of a small girl calling out “Daddy, Daddy! Come with me. Come home. Daddy!”
    • Then in reply the Vietcong ghost answers “Who is that? Who is calling me? My wife? My daughter? Your father is back home with you, my daughter! Your husband is back at home with you my wife. But my body is gone. I am dead, my family. Tragic… how tragic.” and he goes on to tell all his friends and family that he is now dead and that he is in hell. He says how senseless his death was. He pleads with his friends to give up and be reunited with their own loved ones to avoid the regret he is feeling now. “Go home! Go home friends before it is too late!”
  • To our ears this recording is obviously fake.
    • But this was over 50 years in the past. People weren’t quite as used to hearing altered audio as we are today.
      • Engineers gathered for weeks in a studio located in Saigon to record this tape and south Vietnamese voice actors were hired to play the soldiers. They did their recordings in an echo chamber.
    • That being said, most American troops didn’t think Operation Wandering Soul would be believed by the enemy. They thought the Vietcong would see right through their deception.
    • Whether it was believed or not, the audio did manage to terrify troops on both sides of the conflict.
      • And can you blame them.? In a pitch dark jungle in the midst of a war I imagine even the fakes of of horrors would still manage to creep you out.
      • The US played these tapes in the trees near enemy troops for HOURS.
      • Even if the Vietcong didn’t believe the ruse, they did believe that their souls might be cursed to wander forever in pain as that was their religion. So they might not think it was an actual wandering soul crying out, but it did remind them that they might end up that way.
      • Near by civilians who heard the tapes often were fooled by it. They didn’t understand the technical side of the tapes and were already a superstitious people.
  • There were other tapes
    • One tape started with women and children crying. Then an announcer pleading to the Viet Cong to throw down their arms so that no more children would die for communism. Then the cries turned to laughter and the announcer urged the Viet Cong to return to their families and to not ignore the laughter of their children.
    • Another tape titled “No Dose,” implying that no solider could sleep while it played, featured a child saying to his mother “you miss daddy. I miss daddy too. Why doesn’t he come back? He must not miss you. He has left us mother.”
    • These tapes werent just played in the jungles. The US also strapped speakers to helicopters and played it from the air.
      • These speakers were in the way and made it so the helicopter couldn’t return fire to the enemy. And EVERY time these tapes were played the Vietcong fired at the source. So the US would send a gunship with the helicopter carrying the speaker and open fire at the first sign of a enemy fire.
      • Sometimes the tapes were played with another piece of audio equipment known as the laugh box. This played a shrill laughing sound over the tapes and even creeped out the pilots setting it off.
  • Was the operation affective?
    • The extent of the operation’s success is unknown. The Viet Cong usually returned fire upon encountering the recordings, exposing their general positions to U.S. patrol groups within audible range to hear the gunfire over the loudspeakers. While occasionally helpful to U.S. scouts in a reconnaissance manner (i.e. during low visibility), the Viet Cong’s aforementioned responses thus nullified the intended outcome of the operation.
    • So no, it wasn’t that affective.
      • Some think Operation Wandering Souls even motivated the enemy to keep on fighting. They became even more determined to destroy their enemy who would play such psychological tricks.
      • Plus, as soon as the tapes were played they were fired upon and some US soldiers were in the line of fire from that.
    • Local farmers and merchants who worked near where the tapes had been played refused to return to work. They perceived the recordings as black magic.
    • The US military outside of the 6th Psychological Batallion was opposed to the operation.
      • Their opinions were reinforced when many a US soldier was kept awake at night by the sounds of their own country’s psychological weapon.
    • Another psychological tactic was used by the US when they dropped leaflets of a US General describing how he had won a battle against the North Vietnamese enemy, but allowed the enemy to retrieve their dead and carry their wounded to safety.
      • In contrast this operation used the carrot and not the stick. The result was that the North Vietnamese were more likely to surrender peacefully. This operation was regarded as the more affective psychological operation in Vietnam by some psychological operations members.
  • What do I think?
    • My initial reaction to hearing about Operation Wandering Souls was that of shame. I thought “how dare the US resort to such low tactics!”
      • But I quickly realized that opinion was based in a thick layer of hubris. I have no idea what war is like. I have no idea what all was done by each side apart from what the reports say.
      • Compared to the middle ages, Operation Wandering Souls is damn near harmless
        • During the Middle Ages, victims of the bubonic plague were used for biological attacks, often by flinging fomites such as infected corpses and excrement over castle walls using catapults. Bodies would be tied along with cannonballs and shot towards the city area.
    • So although Operation Wandering Souls may seem terrible to us, it was a essentially a bloodless tactic. Terrifying, creepy, and all together messed up… but bloodless.
