Your comment says someone or something lowered the pressure in one SRB to match the pressure in the failed SRB because it was lower. Can you tell me how that is possible in a solid fuel rocket?
lol this little movie made by a kid is so pro-american. you should not tell how great the nasa is/was but how lame they were at handling the situation and so full of proud that they were unable to tell : ' ok we f***"". no it's God will . yeah sure.
@usmctate, the commision that was put together by the government decided that no one person was to blame. One of the managers at Morton thyical was in fact promoted and most of the NASA staff involved are still working for NASA. Very poor communication between the to enitities and lack of REAL concern for the safety of the crew. Though, I'm sure none of them wanted this to happen. The high pressure for success seemed to outway the possiblities of failure.
@thatguy126 OS you think putting billions of more dollars into an off project would rebound the economy? Besides, he shuttles were getting old, we even had to pull one of them out of retirement. Let the Russians get their time to shine in the space industry.
@hawker445 if you just read a newspaper it was reported that russia failed yet again at a mission to mars. Also many of the new technologies developed are because of the space program. I agree that cutting needs to happen and no matter where it happens someone will not be happy, but the amount that was cut from NASA i think was a little harsh for what it provides.
@thatguy126 That was over a month ago. It wasn't going to mars the planet it was a moon. It's not their fault that the probes booster malfunctioned. Besides, Russia and the ESA are the only ones to prove that it is possible fora human to sit in isolation for 1 1/2 years on a possible mission to mars. Nasa sent so man y foreigners to space. Let some other countries take it and give them a shot. NASA, ESA and russias space agency need to work together on a mars mission.
@thatguy126 Not exactly. That kind of job(s) isn't for the average worker. We have the technology, Its just the time to get there. Plus in an emergency mid flight. Who is going to rescue them?
Excellent Presentation. I heard the Lead Morton Thiokal Engineer who was at NASA speak, He was the one who refused to sign off on the launch. This has become a classic case study of integrity and ethics. May we learn and never forget. We can never reduce tragedy to 0%, but we can hear all principle parties. Some comments are regrettably trite. Let's learn and apply to all industrial, governmental, and personal decisions. Don't let the tragedy go to waste. That would be the ultimate tragedy!
we will never forget them, nor the last time we saw them, this morning, as they prepared for the journey and waved goodbye and 'slipped the surly bonds of earth' to 'touch the face of god
I like when "the temperature dipped down into the lower 20s" the video showed the thermometer join into the 20s for celsius when it should have been fahrenheit.... EPIC FAIL
I have problem about the fancy new shuttle that doesn't even exist and you put it in the disaster of challenger's video. what's with that? put it in other video. Idiot
Excellent video thanks for posting. Only suggestion is diction lessons for the narrator. He needs to enunciate better. His word are all run together and garbled and swallowed. It makes it difficult to follow.
we will never forget them, nor the last time we saw them, this morning, as they prepared for the journey and waved goodbye and 'slipped the surly bonds of earth' to 'touch the face of god
you know florida has the stricktest laws of all the states so why WASNT ALL THEM IN FAVOR OF THE LAUNCH ARRESTED ON MAN SLAUGHTER CHARGES they was told and warned of the disaster that was going to unfold if they launched
@coldestghost Launch is not decided by the people in Florida by themselves. Launch is decided by Nasa management (Washington, Houston & Florida), the makers of the booster, the makers of the tank and the makers of the orbiter. Also the crew votes on launching or not. Then you have all the different engineering groups on top of that. The list goes on.....
This video was very well done and narration was fine-good job!
I remember this incident well. I was in junior high at the time and home sick that day so I watched it on t.v. with my mom. It went from exciting to horrifying. I couldn't believe it.
I also remember going back to school the next day and my physics teacher-who you'd think would be mature-asking us KIDS how we knew the astronauts had dandruff. Then he joked 'Because heads and shoulders washed up on the beach.' I never did like him.
@bajesus666 1 out of 70 is considered far far too high a failure rate for human spaceflight. When the Saturn Vs flew they demanded 100% reliability and never lost a crew in flight.....
Scientist viewpoint: There were 4000 critical systems on the shuttle. Success= (1-x)^4000, for small x, failure ~ 4000x. Engineers estimated failure at 1/400 (x~1/1.6mill). Bureaucrats (looking for funding) told congress 1/100,000 (x=1/400 mill). We don't have that kind of technology. One of our best satellite techs died on this mission because he was bumped off earlier flights by Bill Nelson (D-FL) and Jake Garn (R-UT). Political / bureaucratic failure.
Well made and professionally narated, and exact to the point. But what a waste, of lives, just because of greedy subcontractors, not wanting to lose billions of dollars, and future employment from NASA.
I am shocked and saddened that the problem was this well known and that NASA and the SRB developer put 7 people's lives in such danger. An informing and interesting video that properly explains the Challenger accident. 5 stars to the maker.
Overall an outstanding--and truthful--account of on of our worst national tragedies.
I like the frankness of the causes, as well as the upbeat outlook for our space program (though this has changed with the Obama Administration).
One (minor) correction: the full name of the teacher in space was Sharon Christa McAuliffe. Her name was never "Christina", as "Christa"--as she was widely known--was really her middle name.
YOur right, it was no accident, it was corprate greed that brought challenger down THe blood if the astronauts abord that shuttle is on the hands of those responsible for voting to launch.
Good job on the video. Ignore the ignorant comment saying "it sucks". Richard Feynman is the scientist that took some o-ring material and put it in his ice water (at the NASA hearing) to prove that the o-rings are not flexible below 32 degrees. You may be interested in his work. We need motivated people like you, in the field of Physics.
Short term failure was managerial failure. The REAL failure was design. No escape system and the use of SRB's to transport people. Solid rocket fuel is a bad idea because is cannot be turned off. Making the Shuttle parallel with the main fuel tank was also bad. Entering the atmosphere with a winged shaped craft, also a bad idea. To add insult to injury the cost of shuttle was 1.6 billion per launch. Thus, we could have up to 60 disposable rocket launches for the same cost.
if you watch the full launch, along with the info here, you hear the command to throttle up the space shuttle main engines, the extra vibration of the ssme throttling up caused the external tank to shatter because the plume broke through the foam.
The engineers did have a final say and were fully included in the final decision. They were in the conference room when NASA asked if there were any final objections to a launch the next day. Nobody in the room said yes or no and the rest is history.
The engineers had already strongly stated their case opposing the launch, but NASA didn't want to hear it. NASA was determined to launch so management at MT caved in to NASA. The engineers were heard, but NASA didn't listen.
Obviously not, they kept going. Until 2003 when the final accident happened. Remember the "Columbia" Space Shuttle?
After all, there has only been one more Mission after 2003 and that one went nearly as bad as in the year ahead. The "Discovery" got the same problems, but made it to landings.
@Rodnox Yeah I commented before I'd seen the whole thing. Honestly this is disturbing in so many ways. I mean casually risking peoples lives to avoid a delay? Well at least the crowd got a spectacle. I also think they should have done a lot more for the Columbia, I mean they could have done SOMETHING, ANYTHING.
I'm sure you are right about how that happend. I have read about all of that on a NASA website, and you didn't say the exact same, but it was similar.
As soon as NASA gave the go for throttle up and challenger responded with throttle up, it then exploded. I find it highly suspicious that they did not scrub the mission when a problem was noticed and instead went ahead with throttle up.
7 minutes into this: It was cold. The o-rings froze. The designer knew this was bad. NASA didn't care. Shuttled Launched. O-Ring failed. Fire and gas escaped. Rocket Booster explodes, taking the large fuel tank with it, causing the orbiter to break up. All astronauts died.
GOOD GOD WHY DIDNT THEY CARE ABOUT THE SAFETY OF THE DAM CREW IF IT NEEDED TO BE HIGHER DEGREES WHY DIDNT THEY wait? i mean sure they really wanted to launch but geez if they wanted to have them safe atleast have it "SAFE" to launch?? ugh thats just weird
@InSaNiTyReiGnZ it wasn't an explosion, the shuttle ripped apart under enormous aerodynamic forces as it was slightly past max q. Secondly because the fuels are cryogenic.
This is disgusting too say the least - nasa managers blatantly ignoring both the engineers and thiokl regarding the weather being too cold to launch. These managers had NO IDEA about the o rings becoming brittle when it turned cold and possibilly creating a gap. Of course, as managers they had the " where higher than you" .
Do you want the truth? The SRB’s are made of cylinder segments stacked like cans and seated into slots. On Saturday, Jan. 25th, 1986, a crane struck the side of the shuttle. This fact was reported in different newspapers & Newsweek magazine. The strike misaligned the segments. That was the root cause of the accident. This fact was intentionally ignored by the Rogers Commission. The blame was placed on Morton Thiokol for a NASA spacecraft&pad safety management mistake. That is the truth.
What does that have to do with anything I simply think that if u don't want comments u shouldn't respond to outspoken opinionated people such as myself I take history seriously by the way it's spelled "challenger" get a life moron
I hate it how our government always rushes things and creates disasters like these. And also I wonder when those new shuttles will come out, cuz it's 2011 and they still haven't made one
this is bullshit because when the shuttle exploded the boosters keep going witch means the boosters where okay in the cold weather it was a problem with a leak witch caught the flames causing the shuttle to explode and if you pay attention to the boosters going after the shuttle explodes then you will see that the right booster gos longer then the left one so the right pressure thing is bullshit if you are going to try to tell history get it right mmkay
@hudfadz Yeah, but it wouldnt help them. They would need a fireproof capsule, such as those you find in scifi games like EVE online. This proves how short we have come in the age of space. It's still on a pioneering stage, as we still need rocket fuel to propell thru space. In the future it might be flying saucers, or i dont know, but these vessels are very primitive enginewise.
NASA is a bunch of frigging morons!!! Every single "Manager" that made the decision to launch should have been arrested and charged with 2nd degree Murder. They knew there was a problem, but ignored it. History would then repeat itself in the loss of the Columbia, where they again knew there was a problem after launch, but failed to address it prior to re-entry.
So this is a horrible question, but so they knew they were going to die? I thought it happened so fast, but now that u state NASA knew the problem and told them to adjust the pressure in the boosters that would mean my worst fear; that they new they were goin to die.
I'd like to say a few words but i'd either go on for hours or not get the words right. Instead, I wrote a song. It's now 25 years old to the day but please have a listen to it on my YouTube account.
@littleneddygoestowar it was not an accident, nothing involving machinery is an accident. It was a MANAGERIAL FAILURE. The managers FAILED to consult the engineers who know about the limitations of the SRB's. It was the coldest shuttle launch ever.
Nothing involving engineering disasters is an accident. Negligence, greed, and disregard for the limitations of machines will always cause what you call "accidents".
@shaygahweh Not exactly. Considering that the space shuttle has 2.5 million, there are literally thousands of things that can go wrong. You can't simply say that the sole cause of any engineering disaster is human related.
@shaygahweh yeah the engineers could have saved the day, but hey what the fuck do they know? now in 2011 we have to much managers not listening to engineers
@shaygahweh What the hell are you talking about? You can have a mechanical accident. For example, if a pipe carrying liquid fuel cracks and sprays fuel all over the inside of one of the engines and it ignites and explodes, that's a mechanical failure.
@Finkletonian Yes, but in the case of the Challenger they actually knew this would happen if they let it start. It's that simple. That's why it isn't an "accident".
Also, the worry was that any failure in the o-ring would cause the whole vehicle to blow up before it ever cleared the tower. And the puffs of black smoke prove it. The only thing that prevent it, was that some of the burned debris and soot caused a temporary seal. 51L had the most wind sheer seen on any flight up to date. And it had went thru the worst of the sheer just tens of seconds before the flame was seen breaching the right hand SRB. The sheer destroyed the temp. seal...
Um...you said that they 'throttled down' the left booster to match the lower pressure in the right booster? Once the solids are lit, you cannot throttle them. What they CAN do, is when loading the propellant in the booster, channels can be formed into each segment to properly give the booster more or less thrust. But it is done BEFORE the segments ever leave Thiokol.
YOU CANNOT THROTTLE SOLIDS.
and the engineer who most voiced a concern to launch was Roger Boisjoly.
@kgb474 In the ocean of uninformed opinions that seem to plague Youtube, it's good to see a person state some highly informed facts. Your info on the wind shear and transient seal of the SRB O-ring seals is spot on accurate.
LMAO...yea theres a few "errors!" LMAO...the same idiots who say we never went to the moon?...and that JFK is till alive as room mate of Elvis...Wonder what the Booster readings are after seperation on a "normal" flight....BTW No such thing...
@TheArmando1014 OMG this is a horrible video - terrible in accuracies. NASA did not know what was happening as it occured - all appeared to be fine. The did not "lower the chamber pressure in the left SRB" to counteract anything - you CAN"T DO ANYTHING TO THE SRBs!! WHERE DO THEY COME UP WITH THIS SHIT!??!
Good info but horrible quality of video

After all, there has only been one more Mission after 2003 and that one went nearly as bad as in the year ahead. The "Discovery" got the same problems, but made it to landings.

@Rodnox Yeah I commented before I'd seen the whole thing. Honestly this is disturbing in so many ways. I mean casually risking peoples lives to avoid a delay? Well at least the crowd got a spectacle. I also think they should have done a lot more for the Columbia, I mean they could have done SOMETHING, ANYTHING.

I'm sure you are right about how that happend. I have read about all of that on a NASA website, and you didn't say the exact same, but it was similar.

As soon as NASA gave the go for throttle up and challenger responded with throttle up, it then exploded. I find it highly suspicious that they did not scrub the mission when a problem was noticed and instead went ahead with throttle up.

7 minutes into this: It was cold. The o-rings froze. The designer knew this was bad. NASA didn't care. Shuttled Launched. O-Ring failed. Fire and gas escaped. Rocket Booster explodes, taking the large fuel tank with it, causing the orbiter to break up. All astronauts died.

Kpilot786457 9 months ago
@InSaNiTyReiGnZ it wasn't an explosion, the shuttle ripped apart under enormous aerodynamic forces as it was slightly past max q. Secondly because the fuels are cryogenic.
This is disgusting too say the least - nasa managers blatantly ignoring both the engineers and thiokl regarding the weather being too cold to launch. These managers had NO IDEA about the o rings becoming brittle when it turned cold and possibilly creating a gap. Of course, as managers they had the " where higher than you" .

jermeen777 9 months ago
Do you want the truth? The SRB’s are made of cylinder segments stacked like cans and seated into slots. On Saturday, Jan. 25th, 1986, a crane struck the side of the shuttle. This fact was reported in different newspapers & Newsweek magazine. The strike misaligned the segments. That was the root cause of the accident. This fact was intentionally ignored by the Rogers Commission. The blame was placed on Morton Thiokol for a NASA spacecraft&pad safety management mistake. That is the truth.

this is bullshit because when the shuttle exploded the boosters keep going witch means the boosters where okay in the cold weather it was a problem with a leak witch caught the flames causing the shuttle to explode and if you pay attention to the boosters going after the shuttle explodes then you will see that the right booster gos longer then the left one so the right pressure thing is bullshit if you are going to try to tell history get it right mmkay

It's still on a pioneering stage, as we still need rocket fuel to propell thru space. In the future it might be flying saucers, or i dont know, but these vessels are very primitive enginewise.

NASA is a bunch of frigging morons!!! Every single "Manager" that made the decision to launch should have been arrested and charged with 2nd degree Murder. They knew there was a problem, but ignored it. History would then repeat itself in the loss of the Columbia, where they again knew there was a problem after launch, but failed to address it prior to re-entry.
warrior12473 1 year ago
So this is a horrible question, but so they knew they were going to die? I thought it happened so fast, but now that u state NASA knew the problem and told them to adjust the pressure in the boosters that would mean my worst fear; that they new they were goin to die.

littleneddygoestowar 1 year ago
@littleneddygoestowar it was not an accident, nothing involving machinery is an accident. It was a MANAGERIAL FAILURE. The managers FAILED to consult the engineers who know about the limitations of the SRB's. It was the coldest shuttle launch ever.
Nothing involving engineering disasters is an accident. Negligence, greed, and disregard for the limitations of machines will always cause what you call "accidents".

@shaygahweh Not exactly. Considering that the space shuttle has 2.5 million, there are literally thousands of things that can go wrong. You can't simply say that the sole cause of any engineering disaster is human related.

@Finkletonian Yes, but in the case of the Challenger they actually knew this would happen if they let it start. It's that simple. That's why it isn't an "accident".

Also, the worry was that any failure in the o-ring would cause the whole vehicle to blow up before it ever cleared the tower. And the puffs of black smoke prove it. The only thing that prevent it, was that some of the burned debris and soot caused a temporary seal. 51L had the most wind sheer seen on any flight up to date. And it had went thru the worst of the sheer just tens of seconds before the flame was seen breaching the right hand SRB. The sheer destroyed the temp. seal...
kgb474 1 year ago 2
Um...you said that they 'throttled down' the left booster to match the lower pressure in the right booster? Once the solids are lit, you cannot throttle them. What they CAN do, is when loading the propellant in the booster, channels can be formed into each segment to properly give the booster more or less thrust. But it is done BEFORE the segments ever leave Thiokol.
YOU CANNOT THROTTLE SOLIDS.
and the engineer who most voiced a concern to launch was Roger Boisjoly.
kgb474 1 year ago
@kgb474 In the ocean of uninformed opinions that seem to plague Youtube, it's good to see a person state some highly informed facts. Your info on the wind shear and transient seal of the SRB O-ring seals is spot on accurate.
