BREVARD COUNTY, FLORIDA — Today marks the 33rd anniversary of the Space Shuttle Challenger disaster (Mission STS-51-L), when the shuttle’s seven astronauts were killed by an explosion.
The Challenger 7 Crew included Michael J. Smith, Dick Scobee, Ronald McNair, Ellison Onizuka, Christa McAuliffe, Gregory Jarvis and Judith Resnik.
On January 28, 1986, the NASA shuttle orbiter mission STS-51-L and the tenth flight of Space Shuttle Challenger (OV-99) broke apart 73 seconds into its flight, killing all seven crew members, which consisted of five NASA astronauts and two payload specialists.
The spacecraft disintegrated over the Atlantic Ocean, off the coast of Cape Canaveral, Florida, at 11:39 EST (16:39 UTC). Disintegration of the vehicle began after an O-ring seal in its right solid rocket booster (SRB) failed at liftoff. The O-ring was not designed to fly under unusually cold conditions as in this launch.
Its failure caused a breach in the SRB joint it sealed, allowing pressurized burning gas from within the solid rocket motor to reach the outside and impinge upon the adjacent SRB aft field joint attachment hardware and external fuel tank. This led to the separation of the right-hand SRB’s aft field joint attachment and the structural failure of the external tank. Aerodynamic forces broke up the orbiter.
The crew compartment and many other vehicle fragments were eventually recovered from the ocean floor after a lengthy search and recovery operation. The exact timing of the death of the crew is unknown; several crew members are known to have survived the initial breakup of the spacecraft. The shuttle had no escape system and the impact of the crew compartment with the ocean surface was too violent to be survivable.
The disaster resulted in a 32-month hiatus in the shuttle program and the formation of the Rogers Commission, a special commission appointed by United States President Ronald Reagan to investigate the accident.
The Rogers Commission found NASA’s organizational culture and decision-making processes had been key contributing factors to the accident, with the agency violating its own safety rules. NASA managers had known since 1977 that contractor Morton-Thiokol’s design of the SRBs contained a potentially catastrophic flaw in the O-rings, but they had failed to address this problem properly.
NASA managers also disregarded warnings from engineers about the dangers of launching posed by the low temperatures of that morning, and failed to adequately report these technical concerns to their superiors.
Approximately 17 percent of Americans witnessed the launch live because of the presence of Payload Specialist Christa McAuliffe, who would have been the first teacher in space.
Media coverage of the accident was extensive: one study reported that 85 percent of Americans surveyed had heard the news within an hour of the accident. The Challenger disaster has been used as a case study in many discussions of engineering safety and workplace ethics. – Wikipedia
Following is the transcript from President Ronald Reagan’s speech to the nation after the disaster:
“Ladies and gentlemen, I’d planned to speak to you tonight to report on the state of the Union, but the events of earlier today have led me to change those plans. Today is a day for mourning and remembering.
Nancy and I are pained to the core by the tragedy of the shuttle Challenger. We know we share this pain with all of the people of our country. This is truly a national loss.
Nineteen years ago, almost to the day, we lost three astronauts in a terrible accident on the ground. But we’ve never lost an astronaut in flight; we’ve never had a tragedy like this. And perhaps we’ve forgotten the courage it took for the crew of the shuttle; but they, the Challenger Seven, were aware of the dangers, but overcame them and did their jobs brilliantly. We mourn seven heroes: Michael Smith, Dick Scobee, Judith Resnik, Ronald McNair, Ellison Onizuka, Gregory Jarvis, and Christa McAuliffe. We mourn their loss as a nation together.
For the families of the seven, we cannot bear, as you do, the full impact of this tragedy. But we feel the loss, and we’re thinking about you so very much. Your loved ones were daring and brave, and they had that special grace, that special spirit that says, “Give me a challenge and I’ll meet it with joy.” They had a hunger to explore the universe and discover its truths. They wished to serve, and they did. They served all of us.
We’ve grown used to wonders in this century. It’s hard to dazzle us. But for 25 years the United States space program has been doing just that. We’ve grown used to the idea of space, and perhaps we forget that we’ve only just begun. We’re still pioneers. They, the members of the Challenger crew, were pioneers.
And I want to say something to the schoolchildren of America who were watching the live coverage of the shuttle’s takeoff. I know it is hard to understand, but sometimes painful things like this happen. It’s all part of the process of exploration and discovery. It’s all part of taking a chance and expanding man’s horizons. The future doesn’t belong to the fainthearted; it belongs to the brave. The Challenger crew was pulling us into the future, and we’ll continue to follow them.
I’ve always had great faith in and respect for our space program, and what happened today does nothing to diminish it. We don’t hide our space program. We don’t keep secrets and cover things up. We do it all up front and in public. That’s the way freedom is, and we wouldn’t change it for a minute.
We’ll continue our quest in space. There will be more shuttle flights and more shuttle crews and, yes, more volunteers, more civilians, more teachers in space. Nothing ends here; our hopes and our journeys continue.
I want to add that I wish I could talk to every man and woman who works for NASA or who worked on this mission and tell them: “Your dedication and professionalism have moved and impressed us for decades. And we know of your anguish. We share it.”
There’s a coincidence today. On this day 390 years ago, the great explorer Sir Francis Drake died aboard ship off the coast of Panama. In his lifetime the great frontiers were the oceans, and an historian later said, “He lived by the sea, died on it, and was buried in it.” Well, today we can say of the Challenger crew: Their dedication was, like Drake’s, complete.
The crew of the space shuttle Challenger honored us by the manner in which they lived their lives. We will never forget them, nor the last time we saw them, this morning, as they prepared for their journey and waved goodbye and “slipped the surly bonds of earth” to “touch the face of God.”
