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.

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.

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. .."

A quirk of #space #history put all the the anniversary dates for #NASA crewed spaceflight tragedies a few days apart in late January and Feb 1.
• #Apollo1 pad fire: Jan 27, 1967 (59 years, 3 dead)
• Challenger #STS51L launch explosion: Jan 28, 1986 (40 years, 7 dead)
• Columbia #STS107 re-entry breakup: Feb 1, 2003 (23 years, 7 dead)
NASA holds a single "Day of Remembrance" one day each January, which was earlier than the historic dates this time, held Jan 22. https://www.nasa.gov/dor/

Watched the launch live on German television. Noticed gray smoke, which I hadn't seen at any previous launch. Knew immediately that something went wrong with one of the SRBs.

I was frustrated and annoyed by the endless search for the cause and the ignoring of the obvious.

Had problems with my chemistry teacher because he just couldn't get to the point.
Now sometimes I think: Murder by management.

I hope they're making better estimates regarding Artemis II and its heat shield.

Challenger: The disaster five people saw coming

Forty years ago, the Challenger space shuttle disintegrated just after lift-off, killing its crew and changing the history of spaceflight. A small team of engineers tried to prevent the tragedy — but they were overruled.

38 years ago, Jan 28, 1986: #STS51L #Challenger launch explosion, 7 dead. "Go Fever" was again a core factor, the rush to launch amid known risks, in this case cold #weather making booster o-rings inflexible. https://www.nasa.gov/challenger-sts-51l-accident/ #NASA #DayOfRemembrance #space #history

Ansehen! So gut, so wichtig, so richtig.

I was just a kid, but I remember it well. The confusion, the slow motion horror, all framed so jarringly against that blue sky.

37 years later, I still know all their names.
