    Not only did they broadcast the explosion they also caused it. Haha(not funny)

    Richard Feynman was the one who let slip innocently what the cause was during an international press conference and made a lot of people in Washington very very mad.

    Basically, the Whitehouse pushed NASA to launch despite the weather being too cold and that caused an expansion joint of an SRB to fail.

    Feynman showed the world what happens to the expansion joint material by putting it in some ice water for five minutes during the press conference and showed it crumbled after he took it out of the glass.

    That man was an international treasure and I miss him very much.

    The interesting thing isn’t how many fatalities NASA has had but rather how few they have had. Exploration has always gotten people killed.

      I feel you don’t know what you’re talking about in this situation. It is well documented that if NASA had followed their own safety guidelines and listen to their own people, this would not have happened. So many people were waiting to watch the launch that NASA leadership felt they couldn’t abort. That is the sole reason this tragedy occurred, not “whoopsie daisy that sucks but we learned something” science.

      The issue was that they knew there were issues with the shuttle and had been warned by several engineers about launching in the cold weather they were having at the time, but NASA ignored them and sent the Challenger on its way anyways. It’s been awhile so I forget the details of exactly what it was that was wrong, but I think it was the metal in some screws that wasn’t able to deal with the differences in temperatures and the engineers said shit would go wrong if they didn’t replace them and nobody listened. It was a very preventable disaster that only happened due to laziness and impatience on NASA’s part.

      • it was the rubber in the O-ring seals that couldn’t handle the differences in temperature.

        That more of a problem with the manufacturer, (Morton Thyiokol) telling NASA the o-rings were fine to fly coupled with NASA’s desire to prove the shuttle could fly in that low temp condition.

          From Wikipedia:

          Cecil Houston, the manager of the KSC office of the Marshall Space Flight Center in Alabama, set up a three-way conference call with Morton Thiokol in Utah and the KSC in Florida on the evening of January 27 to discuss the safety of the launch.

          Morton Thiokol engineers expressed their concerns about the effect of low temperatures on the resilience of the rubber O-rings. As the colder temperatures lowered the elasticity of the rubber O-rings, the engineers feared that the O-rings would not be extruded to form a seal at the time of launch. The engineers argued that they did not have enough data to determine whether the O-rings would seal at temperatures colder than 53 °F (12 °C), the coldest launch of the Space Shuttle to date.  During this discussion, Lawrence Mulloy, the NASA SRB project manager, said that he did not accept the analysis behind this decision, and demanded to know if Morton Thiokol expected him to wait until April for warmer temperatures.  Morton Thiokol employees Robert Lund, the Vice President of Engineering, and Joe Kilminster, the Vice President of the Space Booster Programs, recommended against launching until the temperature was above 53 °F (12 °C).

          When the teleconference prepared to hold a recess to allow for private discussion amongst Morton Thiokol management, Allan J. McDonald, Morton Thiokol’s Director of the Space Shuttle SRM Project who was sitting at the KSC end of the call,  reminded his colleagues in Utah to examine the interaction between delays in the primary O-rings sealing relative to the ability of the secondary O-rings to provide redundant backup, believing this would add enough to the engineering analysis to get Mulloy to stop accusing the engineers of using inconclusive evidence to try and delay the launch.  When the call resumed, Morton Thiokol leadership had changed their opinion and stated that the evidence presented on the failure of the O-rings was inconclusive and that there was a substantial margin in the event of a failure or erosion. They stated that their decision was to proceed with the launch.

          When McDonald told Mulloy that, as the onsite representative at KSC he would not sign off on the decision, Mulloy demanded that Morton Thiokol provide a signed recommendation to launch; Kilminster confirmed that he would sign it and fax it from Utah immediately, and the teleconference ended.  Mulloy called Arnold Aldrich, the NASA Mission Management Team Leader, to discuss the launch decision and weather concerns, but did not mention the O-ring discussion; the two agreed to proceed with the launch.

          Dunno about you, but it sounds a lot like NASA, especially Lawrence Mulloy, practically twisted Morton Thiokol’s arms until one of them (Joe Kilminster) relented and signed off on the launch. Mulloy even lied by omission at the end there to get his way. I wonder how he could sleep at night after this stunt.

    We watched it live in elementary school, most of the kids didn’t get what had happened right away. Our teacher was just standing there stunned until an announcement came on the intercom asking all the teachers to turn it off. They didn’t say anything to us, just tried to pretend like we didn’t just watch people blow up live.

      It’s the “not handling” part that gets us as kids. We knew better. Adults didn’t. In my case, I was in high school, but it was on a “Teacher workday, student holiday” we had each semester. I watched it live on NASA TV, which we had on channel UHF 55 in the DC area. Even the voice of mission control delayed about a minute or two. I remember thinking, “THAT didn’t look good…” but then they said nothing but normal speed and temp readings, so I thought it was just the angle of the chase plane. Only when the famous “forked cloud” appeared that the announcer said, “we have an apparent major malfunction,” or something.

      Maybe it’s because it’s because I just finished reading this section in Range, but I think it’s more than the engineers knew.

      When sociologist Diane Vaughan interviewed NASA and Thiokol engineers who had worked on the rocket boosters, she found that NASA’s own famous can-do culture manifested as a belief that everything would be fine because “we followed every procedure”; because “the [flight readiness review] process is aggressive and adversarial”; because “we went by the book.” NASA’s tools were its familiar procedures. The rules had always worked before. But with Challenger they were outside their usual bounds, where “can do” should have been swapped for what Weick calls a “make do” culture. They needed to improvise rather than throw out information that did not fit the established rubric.

      Roger Boisjoly’s unquantifiable argument that the cold weather was “away from goodness” was considered an emotional argument in NASA culture. It was based on interpretation of a photograph. It did not conform to the usual quantitative standards, so it was deemed inadmissible evidence and disregarded. The can-do attitude among the rocket-booster group, Vaughan observed, “was grounded in conformity.” After the tragedy, it emerged that other engineers on the teleconference agreed with Boisjoly, but knew they could not muster quantitative arguments, so they remained silent. Their silence was taken as consent. As one engineer who was on the Challenger conference call later said, “If I feel like I don’t have data to back me up, the boss’s opinion is better than mine.”

      I think most of us believe decisions should be data driven, but in some edge cases gut instinct is valuable.

      It is easy to say in retrospect. A group of managers accustomed to dispositive technical information did not have any; engineers felt like they should not speak up without it. Decades later, an astronaut who flew on the space shuttle, both before and after Challenger, and then became NASA’s chief of safety and mission assurance, recounted what the “In God We Trust, All Others Bring Data” plaque had meant to him: “Between the lines it suggested that, ‘We’re not interested in your opinion on things. If you have data, we’ll listen, but your opinion is not requested here.’”

                Eastern Ukraine, the Donbass region, is very pro-Russia and very anti-Ukraine. Western Ukraine was shelling them for a decade, post-2014 coup, due to the hard shift from being aligned with Russia to being aligned with NATO. For these citizens, Russian presence is a good thing. Western Ukraine certainly hates that Russia has invaded, but the “hysteria” I am referring to is the kind that thinks even Eastern Ukraine opposes the Russian Federation.

                So no, this isn’t a “pro-Russian” stance, in my opinion. Recognizing western-Ukraine’s shelling of civilians in eastern-ukraine for a decade, and the overwhelming support for Russian annexation of the Donbass region among Donbass residents in Donetsk and Luhansk, is something that even pro-NATO people need to recognize in order to figure out how to best deal with that underlying fact.

      🛰️ Space Race Fatalities Comparison: Soviet Union vs United States

      Aspect 🇺🇸 United States 🇷🇺 Soviet Union
      Total astronaut/cosmonaut deaths 9–10 (incl. test/training accidents) 8 (official)
      On-mission fatalities 3 (Apollo 1, ground test) 4 (Soyuz 1, Soyuz 11)
      Training/test deaths (astronauts) 6+ (e.g. Theodore Freeman, C.C. Williams) 4+ (e.g. Valentin Bondarenko, others possibly unacknowledged)
      Deaths among ground personnel <10 100+ (notably the Nedelin disaster)
      Transparency High (accidents publicized and investigated) Low (many incidents hidden until after 1989)
      Major catalyst event Apollo 1 fire Soyuz 1, Nedelin disaster

      Key Takeaways
      • 🇺🇸 U.S. suffered more astronaut fatalities, including test pilots and training accidents.
      • 🇷🇺 Soviets had higher total human losses, especially among engineers and soldiers during explosive launch and fuel testing incidents.
      • 🔥 The Apollo 1 fire led to sweeping design and safety reforms in NASA.
      • 🚨 The Soyuz 1 and Soyuz 11 tragedies were fatal in-flight accidents; Soyuz 11 remains the only in-space human fatality.
      • 🕵️ The Nedelin disaster, one of the worst rocket catastrophes in history, killed over 100 but was kept secret for decades.
      • 🧾 Transparency and institutional accountability were key differences: NASA publicly investigated accidents; the USSR often concealed failures.

        You can certainly blur the space race with missile development as they were intimately tied on both sides, and if you want to include it then the deaths from the US ICBM disasters need to be included as well, but I do think it’s a bit absurd to uncritically report that 100+ people died in Nedelin when official numbers revealed it to be 54. Plus, wherever you sourced this from is clearly generally biased against the soviets beyond the scope of this report.

    The crew didn’t blow up(src).

    The flight, and the astronauts’ lives, did not end at that point, 73 seconds after launch. After Challenger was torn apart, the pieces continued upward from their own momentum, reaching a peak altitude of 65,000 feet before arching back down into the water. The cabin hit the surface 2 minutes and 45 seconds after breakup, and all investigations indicate the crew was still alive until then.

    We were led out of our classrooms to watch it since we lived in FL. When the launch went pear-shaped, nobody really understood what had happened, we just thought it was part of the fuel tanks dropping away. We went back in, sat down and continued our day. I don’t think the teachers ever told us something went wrong and I found out about it that night at home.

      When the guy who played Mr. Hooper died, they worked that into the show. The cast, sincerely grieving, had to explain to a seven-foot-tall canary that he wasn’t coming back. That’s not really he same kind of intrusion from reality, as acknowledging the same giant fowl fucking exploded on national television.

      The only possible comparison would be if some show had a gimmicky live episode that happened to be scheduled for 9 AM, on a Tuesday, in September of 2001.
