I was watching live in 8th grade. what a shame we didn't get to have the experience of having a teacher give lessons from orbit.
Endeavor replaced Challenger
It's crazy that it was the right rocket booster leaking the fuel that caused the explosion but the booster itself didn't even explode until it was emergency detonated
As an aerospace engineering senior, this story is taught to us to remind us that if we think something could be a problem, you HAVE to speak up especially when lives are at stake. Also the challengers repeated use had nothing to do with the problem it was all o-ring failure due to temperature. Also once the solid rocket boosters were ignited there was literally nothing that could be done because you can’t turn them off.
My stepdads uncle was an air force officer attached to this mission. He insisted that the blame of this landed on the polticans, particularly people within the Reagan Administration, for insisting they proceed with the mission anyway.
He kept on saying this to his grave.
You said that you thought they were approaching Mach 2 because of the speed they were going and at sea level you would be correct, but Mach number changes with temperature of the fluid. So with decrease in temperature you move at a higher Mach number even if you’re going the same velocity
Challenger happened the day after my brother's 7th birthday, and Columbia happened the day before my 16th birthday.
I remember watching the launch in school when I was 5. My Grandma and my step Grandpa were on their honeymoon in Florida watching it in person. I have my Grandma’s pictures that she took as the take off and accident occurred.
New Hampshire was and still is so proud of our Teacher In Space. There is a statue of her at the state house in Concord NH. An elementary school is named after her just down the road from Concord High where she taught. The Christa McAuliffe Planetarium on the grounds of the vocational college in Concord. I was at a class at the vocational collegee in Laconia NH when it happened. I was in my 30's and just out of the Army.
There is Netflix series about Challenger disaster. They describe the reason very well. Very good show.
you should react to nelsons battles in 3d
was a sophomore… watching it in a small classroom… i still remember the silence and squinting into the smoke hoping to see the shuttle fly out… then hoping for a parachute or something… then just not knowing what to say or do.
I was in 8th grade at the time and we ended up having the day off due to cold temps outside so I watched it live at my Grandma’s house and knew right away something bad just happened. This was one of those events that you never forget where you were and what you were doing. The Reagan Assassination attempt and 9/11 were the two other big ones for me. Very sad day!
Reagan: We should continue to go to space and NASA we need for the public to democratize it.
Trump and Elon: We need to shut down NASA and leave it to private companies so they can enrich themselves.
Amazing how much we let go of for billionaires.
My elementary school was named after Christa! The challengers! Rest in peace to the entire crew
The steel rings for those booster rockets where made in Ohio. My father worked at the steel mill that produced them. He's told me about the NASA officials that came down to the plant after the event to inspect his metallurgical samples for the rings. The facility was cleared of any responsibility, and as we now know it was the rubber O-rings that failed.
A reaction to Alternate History Hub's What if Big Bird was on the Shuttle Challenger would be a very valuable reaction.
i was in the 8th grade watching with my classmates live……..
I don't know if anyone else has already done this, but Cody has a video of his own on the Challenger disaster. It's about what if Big Bird was on the shuttle instead of McAuliffe. That seems silly on the surface (and it is), but it's actually a really well-done video. I cannot recommend it enough.
The solid rocket boosters also get reused, the orange tank burns up
I avoid infographics like the plague. It's rife with inaccurate information. It's very poorly done research. They don't verify it.
Endeavour was the one which replaced Challenger in 1992. Discovery first flew in 1984, a year after Challenger.
At one point, Enterprise (originally a test article for atmospheric flights in 1977) was considered to be retrofitted for spaceflight, but NASA decided it would be less expensive to build a new one from spare parts
Dude you look so sleepy, you sure u slept the last 2 days?
Remember coming home from college. I was still watching kids programmes back then as that was pretty much all that was on at that time in the day. I think I probably saw it on a programme called John Craven's Newsround here in the UK, which was a news programme dumbed down for kids. I also remember the joke that quickly did the rounds within days of the disaster – and remember, this was way pre-internet. "What does NASA stand for? Need Another Seven Astronauts." People are cold.
i was a senior in high school
I was on leave from the US Navy. I was 23. I also believe their were 3 others killed in other space missions. I believe it was in the early 70s.
For anyone that hasnt seen it, theres a video i found on the cape Canaveral youtube channel called space shuttle challenger accident investigation, photos, and tv analysis. Its an in depth slightly technical recap with frame by frame breakdown. Probably the best breakdown ive ever seen. What a horrible day. I think the saddest thing for me is the clip of the backup teacher, shes on the roof of a building, cheering and happy to see the shuttle launching. And then of course the disaster. She just climbs down off the roof. Cant imagine the combination of emotions at that moment.
I am too young to have witnessed this, but my mother still recalls seeing the school broadcast and presidential speech with tears in her eyes. Thank you for sharing your knowledge and reaction, emotions and all! This tragedy, which easily could have been devastating for our nation, made us stronger
I was in second grade and remember watching it 😢
What I always found interesting about this is the Russians didn't use solid rockets because once you light them there is no turning them off and releasing them while on is very dangerous as they have no guidance. Basically once you start them you are resigned to whatever happens.
My mom was in grade school and wrote a letter the President Reagan after this happened like I’m sure a lot of kids did. She’s super proud of the fact that she got a letter back from POTUS, she still has it to this day.
The O-Ring design was flawed and the engineers knew that if the O-Rings got too cold they wouldn't seal properly. There were 18 changes to the SMRBs afterwards. The O-Rings got brittle when cold and never sealed. The new design allowed for another O-Ring which meant that it contributed to 15% less rotation than what occurred during the disaster.
There were also software changes to allow for 104% thrust instead of the 109%, with 109% being only used in case of an abort procedure.
Also it wasn't an explosion it was a break up of the components there was no explosion. Also I think there were 2 O-Rings in the initial design but a third was added later.
👍🏻
So just a heads up the infographic show. Tends to get a lot of little details wrong that add up over time.
For example, one of the engineering heads for the boosters was begging them to cancel, the launch due the temperature But the director of NASA is a time overruled him.
Edit: There are better videos on the topic, including at list one documentary That I can thank of off the top of my hand i can link to if you want
For years I took the news of this tragedy at face value, but thirty years after the accident, conspiracy videos started hitting the internet. Some of it was very disturbing. I can’t help but wonder in the back of my mind that maybe we’ve all been played??!!🤔🤔🤔🤔🤔🤔
Awful AI narration
My cousin was the pilot on STS29. The 3rd mission after the Challenger accident. I got to watch the launch live and in person.
There as so many wild inaccuracies in this video by them.
