The #Buran also had emergency ejection seats 💺 for all crew members (absent on the #US shuttles) and was free from the specific design flaws that contributed to the destruction 💥 of two shuttles in flight, the #Challenger in 1986 and the #Columbia in 2003 edition.cnn.com/style/article/

Challenger-Märchenstunde beim SWR 3/3:
".. und irgendwann hat der Booster dem dann nicht mehr standgehalten, wurde zerstört, und das hat dann letztendlich zur ganzen Explosion des Space Shuttles geführt. .."

Auch falsch. Der lecke Booster hat seine Befestigungen am Haupttank und den Haupttank beschädigt. Auch der lecke Booster flog deutlich sichtbar aus der Trümmerwolke heraus.

Challenger-Märchenstunde beim SWR 2/3:

"Eine mangelhafte Dichtung hat dann zur Katastrophe geführt."

Nicht die Dichtung war mangelhaft. Die Berücksichtigung des für ihr Funktionieren notwendigen Betriebsregimes war ungenügend. Bei der Kälte konnte die Dichtung nicht zuverlässig funktionieren.

Die "Challenger" explodiert

28.1.1986 | Die Raumfähre "Challenger" explodiert kurz nach dem Start. Die sieben Astronauten an Bord sterben. Eine Katastrophe der Raumfahrt.
"
Nein, die Raumfähre ist nicht "explodiert". Kommt das auch beim SWR an?

Nicht alles, was eine "feurige Wolke" produziert, ist eine Explosion.

There was no way that one could have confidence that conditions the next time might not produce #erosion three times more severe than the time before. Officials fooled themselves into thinking they had such understanding and confidence, in spite of the peculiar variations from case to case. A mathematical model was made to calculate erosion. This was a model based not on physical understanding but on empirical curve fitting en.wikiquote.org/wiki/Richard_

Have you ever wondered what we learned from the and the teacher who was meant to inspire a generation from ?

This shares important lessons taken from this historic mission

Oggi, a #LineaRadioSavona non c'ero, ma volevo scrivere due righe su quel che sto sentendo in questi giorni.
C'è chi dice che #NASA avrebbe rimandato il lancio di #ArtemisII per via del freddo, "per non ripetere l'esperienza del #challenger ".
Fermi un attimo. NON. È. COSÍ.
Onizuka, McAuliffe, Jarvis, Resnik, Smith, Scobee e McNair non sono morti invano.
I booster, dopo #STS51l sono stati riprogettati, e ora ci sono molti più sensori e riscaldatori che impediscono agli O-rings di raffreddarsi.

🚀❄️ Forty years ago today, the world watched the #Challenger tragedy unfold. It was physicist Richard Feynman who eventually demonstrated the fatal flaw – not with complex #math, but with a simple glass of ice water.

#feynman's observations concerning #challenger, which were published in his memoir "What do YOU care what other people think", is worth being reread periodically. Probably all of us have been in projects where management was deaf with respect to grave technological concerns as it would have spoilt a good yarn that was told to the customer. Obviously, all these projects have the one inevitable outcome, since nature cannot be...

"For a succesful technology, reality must take precedence over public relations, for nature cannot be fooled."

Richard P. Feynman, Appendix F, #challenger Commission Report

"
How Richard Feynman Found the Root of the Challenger Disaster
"
".. O-rings .. these rings were never intended to be used to cover expanding gaps, .. "

".. felt frustrated by the slow pace + “time-consuming” public meetings + briefings “of so little use.” He did his own research .. even created his own report .. released publicly. .."

Just realized at this late hour that today is 40 years since #Challenger.

"There is no downlink..the vehicle has exploded."

Those words are still so chilling. 😢 💔

I get a “This Day in History” email from history.com every day. Today’s one reminded me that 40 years ago, the Challenger space shuttle accident happened https://www.history.com/this-day-in-histor . I was a junior in high school and remember hearing about it over the loudspeaker. So many people were really sad that day. It feels like yesterday, but also a long time ago. #Challenger #SpaceShuttle #ThisDayInHistory
