Remembering the Challenger disaster, 25 years later

Seventy-three seconds.

That's how long NASA's space shuttle Challenger was in the air before an O-ring failure turned a routine mission into space into a tragedy on January 28, 1986.

Twenty-five years after NASA's first fatal in-flight accident, the memory of the Challenger disaster is still strong.

CNN's John Zarrella was at Kennedy Space Center to cover the launch - the first from NASA's new launchpad 39B. "I just remember seeing the cloud of smoke and what looked like fireworks coming out from the vehicle," says Zarrella. "We were all just looking at each other wondering 'OK, what's happened here?'"

CNN, still in its early years, was the only network to carry the launch live that Tuesday. Among those tuning in were children in classrooms across the country, watching what was to be a milestone: Christa McAuliffe, the program’s first teacher in space, lifted off as a member of the crew.

An investigation later revealed a rubber "O-ring" seal on one of Challenger's solid rocket boosters had failed because of unusually low temperatures. This caused a leak of highly explosive gases, which ultimately led to a catastrophic explosion at 46,000 feet.

It would be almost three years before the space shuttle program would return to flight. NASA wouldn't experience another disaster until the loss of space shuttle Columbia in 2003, when a hole in the shuttle's heat shield caused it to disintegrate on re-entry to Earth's atmosphere. The Columbia disaster would ground the shuttle program for another two years.

Seven lives were lost in the Challenger explosion: Dick Scobee, commander; Michael J. Smith, pilot; Ellison Onizuka, mission specialist; Judy Resnik, mission specialist; Ron McNair, mission specialist; Gregory Jarvis, payload specialist; and Christa McAuliffe, payload specialist and teacher.

    OMG, that’s been 25 years already? One of the saddest events in our Nation’s history…I was at work and we were all in our offices watching, and we literally all started wailing and crying. Yes, even the men. We closed the office. We were all just that upset. Even though 25 years have passed, I’ll bet anyone who witnessed that will always remember that day, and the courage of our astronauts, (living and passed) for stepping into the unknown, good and bad. RIP. Their families should know that, imo, they are heroes and epitomize why little boys and girls STILL want to grow up to be astronauts.

    And I WON'T be clicking on the video like; that image is something I will never forget...

      DISASTER….The Astronauts did NOT need to die. Reagan lied in his speech about the disaster forced NASA to launch as he said, “Let the Turkey Go UP!” Rockwell Employees watching first launch of Discovery after disaster, told me they knew for sure The Challenger crew was still alive on the ocean floor calling for help. They heard them. Cmdr. Dick Scobee; pilot Michael J. Smith; mission specialists Judith Resnik, Ellison Onizuka and Ron McNair; and payload specialists Gregory Jarvis and Christa McCucallife did NOT need to DIE!

    Banasy, I also do not need to watch the video. It is another such as Kenedy's assassination or 9-11, that will be engraved in my memory till I die. Even after those events, we still have children that aspire to one day be President or even Fire Fighters. It is odd that theweather today in Florida is almost reminiscent of that cold day all those years ago. And yes, today should be a day of reflection and remembrance.

    Good morning tomcat, banasy. Good to see you both again. I've missed you both, but found banasy last night and got over it. he he And tomcat! How are you? And yeah, I remember Challenger. Back then, most of US were afraid the soviet Union was going to invade US, and anything that even implied the USSR was getting the upper hand scared many. Not unlike today where most are afraid that the terrorists are coming. At least our government understands that international terrorists aren't coming. If the government took the threat of al Qaeda sneaking in, they would have secured our borders years ago. (RIP Challenger and Discovery crew, and I hope to see you all again someday)

      The Space Shuttle Program is successful despite what some may say, anytime you 're dealing with rockets and rocket fuel eventually ther will be a problem. But to fly 25 missions at that point and no serious accident is a testament to our superior ability to build rocket ships.

      The crew knew the risks.. One thing NASA learned from this is to put parachutes in the passenger compartment of that Space Shuttle _ when that explosion occurred the passgenger separated which it was designed to do it shot up 3 more miles, but that descent to the ocean and subsequent hitting that water is what killed them. If parachutes had been deployed and built into that Shuttle they would have survived.

    I remember thinking, Judith Resnik was a hottie. Thought, wow a hot smart chick is going into space. I was watching the launch, then the words throttle up, then boom boom and it was surreal. Hoping for survivors yet knowing there would be none. Then there were milllions of children watching it. Most schools were playing the launch on televisions in classrooms. There was a school teacher aboard.
    The Challenger could not have been any more painful of a disaster. It was a foolish publicity stunt by NASA and I am surprised they survived it. The millions of kids, well they probably would have made good soldiers someday after watching that.
    Nasa survived it by blaming the O rings. Making Americans picture this O ring in their mind and say, it's your fault. When the fact is NASA is in charge of inspecting and inspecting and inspecting every piece of the space shuttle assembly prior to launch. It will be good when they are retired.
    The space shuttles have been a waste of money and have cost the lives of two crews. Have we gotten any further from our planet? No. NASA in my opinion is a bunch of arrogant individuals who have been collecting a paycheck for 25 years with blood on their hands. Not a one of them is capable of thinking outside the box otherwise they would have figured it all out by now. They haven't figured it out because they have been sending human beings into space because they wanted jobs.
    This makes everyone murderers (to a degree) who were working at Nasa when the two shuttles exploded. The fact the crew members are in Heaven is irrelevent.

      NasaGuy. You don't think outside the box. Otherwise 40 years ago, the procedure would have been :
      1.) Find the nearest earth-like planet.
      2.) Genetically alter human babies in their early stages of development to achieve beings that are suited for long distance high speed space travel. Having a larger heart and larger lungs with a bigger brain, smaller stature (shorter and thinner) with superior eyesight, intelligence etc etc etc. You must make space travelers first or you are doomed. It doesn't matter how many beings you lose in the process, the existence of the human race is at stake. Mankind will be lost if you fail.
      3.) You build the spacecraft based on what your space travelers abilities are and the brillance of it all is they will help you to succeed in building the spacecraft.
      4) Your space travelers take one man and woman in early developement to the Earth-like planet.
      Outside the box, not in. In has rules. The seriousness the situation reguires no rules.

      Mr. Brieske,
      I can see that this topic has had you quite frustrated for some time. I'm just sorry that you feel the need to debase yourself to vulgarities in order to feel as though you are heard. There have been difficulties with the space program, that's not being denied, but for you to state outright that there has been no good to come from it, I think is a bit short-sighted. If you are not aware, there are many scientific, agricultural, and medical innovations that have come from experiments performed on many of these missions...some of which I bet you use and are not even aware of.
      Also, since you have this all figured out, why aren't you working for NASA? Why haven't you achieved long-distance, high-speed space travel? Where's your mutant child who solves Einstein's equations during commercials breaks?
      Before you start pointing fingers at those whom you feel have failed, look in the mirror and honestly see if you can do better. If you can, then I am humbled.
      Plus, if you are, in some strange way, honoring the service of the crews, why do you state they have done nothing good? I look forward to your eloquent response.

      STUDENT: There's some things that you must understand about those like Mr. Brieske. With the amount of comments he "excremented" on this blog, it is clear to me that he spends too much time "trolling" these "Comments" that he evidently has no "free time" to:
      1) Read books/articles from credible sources to understand the true, positive impact that those at NASA.
      2) Take time to better himself so he may someday have the skills and knowledge to work at some reputable place NASA rather than overcompensate for his own failures by ignoring the successes of NASA
      3) dedicate time to actually do something worthwhile so he MAY contribute something to society other than scathing, irrelevent and irrational remarks.
      In short, it's not worth the effort to respond to his trashings.

      One note - 3 lost crews during the 50+ years of NASA's existence - with that record of sucesses and failures as well as overall attention to detail and quality, I'd let them design my car ANY DAY!
      God bless the souls of the Challenger crew and to thier families.

      @ Jim Brieski

      Nasa did NOT blame the O rings, it conducted an investigation,
      which concluded the O rings had faulted.

      Why would you think Nasa wanted us to believe it was our fault
      the Challenger blew up??? That doesn't even make any sense!

      Nasa was in charge of inspecting every piece of the shuttle, but
      you also have to realize that Nasa is not a person. It's a group
      of people and no matter how many times you check things out accidents
      are bound to happen. Unfortunately, it's just statistics.

      Nasa will never retire and without space shuttles we wouldn't have
      launched satellites and our technology wouldn't be as advanced (yes,
      space technology has impacted our every day technology).

      Nasa's mission is not just to make space shuttles to take us far from
      Earth.

      Do you think outside the box? Have you figured it ALL out, whatever All means to you?

      From all your comments it is safe to assume you are not a scientist and have no
      appreciation for science. So please don't comment about things you are ignorant about.

      Student. The sole purpose of space travel is to get a reproducing male and female to the nearest Earth-like planet. Your unsolved theories relating to space travel will never be solved by humans.
      I work for God, so fuk you. I have gave the correct procedure for success. Humans are too stupid and they are not designed for high speed long distance space travel. You must develope beings who are much much more intelligent (than human beings), to solve the theories, to design, build and operate a spacecraft.
      And if you ever write to me in condescending tone again, I will be very very angry.

      Are you an American? Odd. Too bad. You are typing and posting to a net that was originally a NASA interface. I know, I worked on it from Cern SZ with NASA in 1979 on what became the WWW. The insanity here in this thread is truly disturbing by so many posters here. At the time of Challenger, I was dating Dr. Judith Resnik (Judy to the rest of us) and was there that morning at KSC. I can tell you categorically your entire post details are totally false. Sad.

      And for you and the others in error, Discovery s still with us and due to for the next launch of STS-133. I think you are trying to refer to Columbia, STS-107, failed 2003. 2 failures in 133 flights, is a success margin unheard of in any mechanical way on Earth. The Shuttle has 761 CRIT items that any one of which to fail, is loss of mission, vehicle and crew.

    I was working at NASA Ames Research Center in Mountain View, CA on that day. The entire 5,000 employee staff and contractors were watching the shuttle launch on NASA-Select TV, in nearly every building on the base. Then the explosion. The entire community gasped. It was absolutely surreal. Everywhere on the base, people were stunned and in shock for the rest of the day. Very few people said much on that day.

    Space shuttle Discovery is still in service, currently scheduled for it's last mission prior to retirement, STS-133, February 24th. Also in service are Endeavor (will retire after STS-134) and Atlantis (will retire after STS-135).

    It was space shuttle Columbia that broke up during re-entry. So yes, Apollo 1, Challenger, and Columbia.
