Shuttle to Launch Despite Objections

sam0ht writes "NASA has just named July 1st as the launch date for the space shuttle Discovery, a year after the last shuttle mission. Last July's mission was the first since the break-up of Columbia in 2003, but after foam again broke away from the main tank, the shuttle fleet was grounded. More foam has been removed from the main tank, but NASA staff are divided over whether this is enough to ensure the flight's safety, with some reporting that both the lead engineer and top safety official are against launching again so soon. Managers want to make only one major change at a time, and plan that if damage does occur, the crew would be able to stay in the International Space Station, to which they are delivering supplies, rather than trying to land a damaged shuttle."

After college, I continued to work in the area of space sciences and now I have several missions under my belt. Having seen how things work from the inside, the majority of good science comes from our unmanned satellites that don't make the news and the majority of the public don't even know about. While there are certain scientific benefits that the shuttle program has brought, the majority of the shuttle program has been a public relations campaign and politics.

At this point the objective is just to kind of keep the shuttle from another catastrophic failure and kind of half finish the ISS. At that point there is a 50/50 chance success will be declared and then they will have to figure out how to abandon the ISS safely since it sucks money out of more worthwhile endeavors, and does next to nothing useful.

Since we don't currently have a reliable manned booster to rotate crew on and off the station (having trashed the working, reliable, relatively inexpensive and more powerful Apollo launcher for the unreliable, outrageously expensive Shuttles), or a reliable means of emergency escape, the ISS is limited to 3 crewmembers on a longterm basis. That's barely enough staff to keep the station running, which means there's virtually no science taking place aboard the station.

    I say abandon the ISS now, along with the Shuttles, and divert those tens of billions of dollars into designing and building a state-of-the-art launcher utilizing the lessons learned from the successful Apollo program and those parts of the Shuttle program (such as the engines) which have proven worthwhile. Or spend that money on researching and developing tech which could dramatically lower the cost of access to space, such as carbon nanotube structures or new propulsion technologies. Either would be a far better use of taxpayer money than the useless ISS or the expensive, unreliable Shuttle, which I believe are now up to a billion dollars a launch, making them the most expensive launcher ever by a wide margin.

That flight had the robot arm installed so they used it to inspect the damage. To the crew the damage looked very bad, but mission control said, repeatedly, not to worry about it. Upon landing they looked at the underside of the orbiter where the foam had hit. The damage was, in fact, very bad. It was the worst tile damage until that which did in Columbia. Mission control later said that the quality of the downlink video from the robot arm was not very good, so to them the damage did not seem as extensive.

      None of the problems which led to the loss of either Challanger or Columbia were new or unknown. Engineers had seen them, had been worried about them, and attempted to make a case to management.

Some back of the envelope math: the trip to orbit is about 200 miles, the trip down the same, and we'll be VERY generous and say the shuttle travels another 100 miles once its up there in positioning changes and whatnot. Thats a total of 500 miles per trip. There have also been 114 shuttle missions over the course of the space program. Thats one death per 4,000 miles. If cars were that much of a deathtrap we'd expect about 450,000 traffic fatalities in 1994. There were about 43,000 last year.

    Bonus points: if you charge the deaths to alcohol instead of cars (hey, the cars would have been perfectly safe if the guy hadn't been driving drunk -- thats like charging a passenger airplane for fatalities if it gets hit with a missile), roughly half of the car fatalities vanish.

    Sounds like the people who were in charge when the first shuttle blew up are back at the helm.

    No, I don't believe that. It was 23 years ago when the Challenger exploded. The people in charge now are the children of the management 23 year ago.

    There's gota be a name for this, perhaps nepodilbertism.

    Originally they didn't plan to strap it to the side of a whopping great rocket and shoot it into space, either. Originally they had planned to have a very large, reusable delta-winged aircraft which the shuttle would clip into (this is one of the reasons why it fits so cleanly onto a 747). The booster aircraft would take the shuttle up to a very high altitude, the shuttle would take off into orbit, and the booster would return back to the ground where it could be re-used. They didn't build it, convinced it would cost too much to put the desired payloads into orbit. In retrospect they probably would have been better with the original idea. Certainly it would have been better then the horrible kludge they came up with.

  32. von Braun and risk management by Beryllium+Sphere(tm) · · Score: 4, Interesting

    Absolutely right: perfectionist, budget-buster, and committed to testing every part before putting them together.

    I highly recommend the new von Braun biography, "Dr. Space".

    One thing NASA has forgotten from his legacy is the need for absolute honesty in engineering. He rewarded people for coming forward and admitting screwups even when they might have been blamed for loss of a vehicle.

    Honesty, safety margins, and a culture of "there's no such thing as 'sort of' working" give you machines that work and that don't kill people. Von Braun's team designed the Saturn first stage. It's entertaining to calculate the total energy that was stored in one of those, and divide it by c squared. 300 milligrams. All released in a few minutes. Von Braun's team made that work safely and successfully every single time.

  33. You're right. What a difference a comma makes... by patio11 · · Score: 2, Informative

    I need to get my eye glasses prescription bumped up again. If you look at the page I linked to, it was a comma there (1,793 billion miles, not 1.793 billion miles), not a period. Which changes the calculation by three orders of magnitude. Doing some additional Googling I found that the NHTSA has broken down the numbers for us: there are roughly 1.51 deaths per *hundred million* miles travelled. This means that, by any definition of "miles travelled" the shuttle is less safe.

    And then, most probably, several decades later, they'll start to protect their corporation, abuse their new patent system, waive personnal freedoms in the name of planetary security, be constantly affraid of imaginary "pedo-terrorist-pirate" that reportedly posses anti-matter weapons, declare wars against anyone standing in the way, etc... ...And history will reapeate itself once again...

    It's apparant, to me, there's NO way to make the Shuttle 100 percent safe....there's no way to make ANY spacecraft 100 percent safe. Space is a hostile environment. The astronauts know this. One thing that cannot be disputed is that the shuttle has flown before with foam ramps falling off the shuttle. What happened to Columbia was very unfortunate, but in my book, it's a freak accident. There are so many variables that had to happen JUST RIGHT in order for the vehicle to be lost. All that can be done is try to minimize it. It can't be prevented. What happens if a Heron or some other big bird is in the way when the shuttle launches? Odds are, a BIRD can bring the shuttle down just as easy as a piece of foam. The odds are very low that this will happen but NOT zero. Does that mean we don't launch?? No.

    What I do see happening is a return to the traditional capsule like format. It could even be done in a reusable format MUCH easier and less prone to problems then the shuttle. We have to keep in mind....space is different. We can't send airplanes into space. We have to send spacecraft into space.

  36. NASA - Nothing About Safety Afterall by ONOIML8 · · Score: 2, Interesting

    When I joined the workforce it was with Uncle Sam: the federal government. That's the same outfit, for those of you who might be unaware, that runs NASA. The federal government is a large and interesting organization that has a rule book for everything and everything is done by the book. Or Else. As it was explained to me, the government doesn't like having to explain replacement of expensive things because of stupid mistakes. They make enough stupid mistakes as it is. They also find it difficult to deal with angry families or foreign nations when these accidents impact those entities.

    My early work experience was very similar to the business of space travel. I worked on high performance fighter aircraft. You had to focus very hard on safety and doing your job right because the danger level was already higher than most people see in their lives. On top of that, I was an armament systems specialist which means that I worked with things intended to blow up or otherwise kill people. Usually these devices were intended to kill large quantities of people or destroy very large and heavily armored vehicles or buildings. Safety was therefore extremely important because you didn't want one of these things going boom at the wrong time or place. Our goal was in fact to have the pilots fly around with these things and bring them back to us in one piece not having killed or destroyed anything. If/when we pulled that off it was A Good Thing(TM) . We were told, and I have witnessed, that if we took the time to do our jobs safely we would be doing them faster and at less cost than if we threw caution to the wind. Yes, I said that I have witnessed it.

    Safety was preached to us all day, every day. We began each day with a mission briefing, a prayer and a safety briefing. On the flightline we started every load with a safety briefing. At the end of the day we debriefed so that we might learn from the experience and be more safe tomorrow. If, at any step of the operation, anyone thought conditions were unsafe, they would speak up and everything stopped until the situation was corrected. It didn't matter if the person crying safety was a general or the newest airman fresh out of tech school and wet behind the ears. The fact that I ended my enlistment with all of my limbs is a testament to this culture of safety. When you consider the dangers involved....it's pretty darn mindblowing.

    If you compare tactical fighter operation with shuttle operation, the danger levels are very similar. Why then do we have NASA willing to launch a shuttle despite their top people saying it is unsafe to do so? When the engineers are saying "STOP", why is the mission allowed to proceed?

    This is not the first time that NASA has had a disregard for safety. In fact it's something of a way of life for them. Remember the Apollo 1 disaster and the hatch that couldn't be opened by the astronauts? And that's not the first such stupid unsafe act they were involved in. NASA and the CIA have always had this acceptable risk culture as part of their flight operations.

    The military has a culture of safety and, although their jobs are extremely dangerous, they do not believe in acceptable risk. The military is always working to make their jobs safer. NASA, on the other hand, has a culture of acceptable risk. They seem to figure that their jobs are dangerous and that's just the way it is. I'm thinking NASA could learn quite a bit from DoD. Yes, I actually typed that.

    If we're ever going to get off this rock, space travel has to become safe. If we're ever going to use space to our advantage it has to become affordable, and that means we can't be accepting high risk all the time. Therefore this culture of acceptable risk is holding back our space program.

    The Russians don't have the safest space program around but they sure have a cheaper space program that is just as active. The Soviets, when they ran the show, had a hell of a lot of stupid accidents. Then again, they have never spent the kind of
