AI Thread Summary
The discussion centers around a recent incident where a tool bag, including grease guns and a putty knife, floated away during a NASA spacewalk, prompting criticism of NASA's procedures and design flaws. Participants express frustration over repeated mistakes in space missions, questioning how such errors can occur given the advanced technology and expertise involved. Some argue that human error is inevitable in high-stakes environments like space exploration, while others emphasize that design improvements, such as better tethering systems, could prevent such incidents. The financial implications of losing tools in space are highlighted, with estimates of the lost toolkit's value reaching $100,000, underscoring the costly nature of these mistakes. The conversation also touches on the broader context of human error in both aerospace and medical fields, debating the severity and consequences of mistakes in each domain. Ultimately, the discussion reflects a mix of frustration, humor, and acknowledgment of the challenges inherent in space missions.

Saw this on on Yahoo this morning; http://news.yahoo.com/s/ap/20081119/ap_on_sc/space_shuttle

Are these people for real? How do you just let a big expensive bag of tools just float away. Have NASA engineers never heard of the amazing invention called the rope? This isn't the first time its happened either. I don't understand how this administration can put a person on the moon yet still make so many stupid mistakes.

Did you even bother reading the article?

As Stefanyshyn-Piper cleaned up a large gob of grease that seeped from a gun used to lubricate the joint, the tool case somehow became untethered from a larger bag and floated away along with a pair of grease guns, wipes and a putty knife attached to it.

"What it boils down to is all it takes is one small mistake for a tether not to be hooked up quite correctly or to slip off, and that's what happened here," said lead spacewalk officer John Ray.

That's like, the third paragraph. And I'm not sure a grease gun and a putty knife can be described as "expensive".

Who is 'this administration'?

A cheap tool becomes pretty valuable once you have lofted it into orbit.
 
I know the astronaut in question quite well - I went to school with her - and can tell you that there is nobody I would trust more to handle a delicate job in difficult circumstances. Spaceflight is still not routine. I doubt very much you would have done any better.
 
I tend to agree that this is ridiculous. Yes, mistakes happen, but this one doesn't require the best minds in NASA to be avoided. I don't know if the astronaut is to blame, but it is certainly an embarrasing and pedestrian level failure of the system.

Yes I did. The fact that a tool bag can even some how become unteathered shows a serious flaw in the design. And it may have just been a tool resembling a butter knife but it was required to complete the repairs. Which in the end means more money and/or more man hours will be required to make that repair.

Thats nice. But I wasn't questioning the astronaut, but the idea of having a way to keep a tool bag where its suppose to be. Thanks for making it personal though.

BTW, I can disassemble a pencil strut on a dodge neon, upside down, with my eyes closed. How do you know I couldn't do any better?
 
One thing that a career in experimental physics has taught me is that when you have a one-of-a-kind task, sometimes it doesn't work the way you think it will. Even if you've thought about it, practiced it, had the whole thing reviewed: sometimes you get surprised. Space exploration is still exploration - filled with these one-off tasks that have not yet become routine.

And I know you can't do it any better, because nobody could do it better.:biggrin:

I want you on our next mission to space. I'm sure the dodge neon they have up there will definitely need professional attention. But, we'll let you do it with your eyes open, just to make sure it all goes to plan :wink:

If you make a tool bag that can't be untethered, then you have to have a specific space suit for every job you do, or a space suit that has all the tool bags permanently attached to it. Stuff fails, that's engineering for you. Whether it's human error or design failure, it's unavoidable after so many missions that nothing goes wrong.

I'm not sure if they have to be designed special for astronauts due to their gloves, but regardless, you do have to pay transportation costs, which are $10,000 a pound. That makes it pretty expensive to have them FedEx you new ones.

No matter what the profession, mistakes are made. Doctors and hospitals will always need malpractice insurance, for example.

I don't think you can compare the accidents in the medical field to those made in aerospace. The ISS has billions of dollars behind it along with thousands of some of the brightest minds this world has to offer. With all of the resources and labor put into the ISS, mistakes should be rare and relatively unheard of. The same can not be said for a surgeon leaving a sponge in a patient or prescribing the wrong subscription.

This is not the first time a bag of tools have been lost in space. These mistakes are expensive, careless, and worst of all they keep repeating.

You're right. One only costs money, whereas the other costs human lives. And mistakes are still made by doctors.

But this is human error. There is always going to be human regardless what you are doing or who is doing it. To think that the probability of such mistakes happening should be zero is naive at best.

I bet if that bag was from Coach she would have remembered it. Sorry. I couldn't resist.

Right now it seems like a stupid mistake until a bag of tools traveling 17,000 MPH crashes into something.

Right on. Doctors are also pretty smart and get lots of training. I'd venture to say even more training than astronauts.

Those wrong presciptions can and do cost lives, a lot higher stake than losing a bag of tools.

When it comes to engineering such things as the ISS, EVERY error is human error. Obviously there will be mistakes as with every project. But mistakes such as this shouldn't be made, especially since it can be solved with $2 worth of Velcro.

True. But you don't have 600 doctors working with a single patient running up a $3.4 billion dollar medical bill. If you did, I bet there would be little or no mistakes.

Wow. The space spider's web has to be added to that video with the crack spider.

Too bad the lack of gravity makes such a mess of spiders' web making abilities. There goes one possible solution to dropping the tool bag.

Anyone who thinks that human error can be eliminated is going to eventually create a disaster. The sensible solution is to figure out what to do after human error is committed (i.e. - make sure you have spare tools, etc.)

Even using that strategy, there's going to be a few tasks where recovery from an error is going to be impossible. These should be few, they're the "critical" tasks, and these should be the few tasks that a person knows so well that the odds of making an error become miniscule.

One of the reasons space missions are a high risk enterprise is that you're never going to simulate a space mission perfectly while on Earth. The only place to get the truly realistic conditions that provide the practice necessary to reduce the chances of error is on the mission itself.

According to Lester Holt tonight, the cost of the lost tool-kit was $100,000. Add in the cost of lofting all that stuff into space, if you care about the details.
