Shuttle Launch Delayed Again, Possibly Until December

An anonymous reader writes "NASA engineers worked overnight trying to fix the electrical problem that forced the launch of space shuttle Discovery to be delayed again. Mission managers will meet later Wednesday to figure out if a launch on Thursday is even possible. The tentative plan is to have Discovery lift off Thursday at 3:29pm. If that does not happen it would be rescheduled for Sunday. If it cannot launch Sunday then it will have to wait until December. NASA engineers have a lot of work on their hands Wednesday morning. Discovery has an electrical issue that forced officials to postpone its liftoff, which had been rescheduled for Wednesday afternoon."

electrical issue???

are you sure it wasn't just a "space shuttle issue"? thanks for being specific, NASA... i'm confident my tax dollars are in good hands.

Re:electrical issue???

[Anonymous Coward]

how many people care that much that NASA's special space cup holder isn't working right vs. "something" not working right? If you really care, look it up on nasa.gov:

"The Mission Management Team, which is meeting today at NASA's Kennedy Space Center in Florida, is discussing one of the main engine controllers on space shuttle Discovery. The controller showed a one-time, irregular power drop. The issue was isolated to Discovery's Number 3 engine and all the connectors were attached and retested. After reviewing the issue, the team is discussing possible causes. You can follow developments in the MMT meeting at www.twitter.com/NASA"

took about a minute to find.

Why bother?

[kurt555gs]

The shuttle was an misconceived expensive piece of junk designed to make the Russians go broke copying it. (Read Buran). We should have never given up on the Saturn V as out heavy lift platform.

Why not just move the remaining Shuttles to museums like the Smithonian and Wright/Pat and display them as the costly mistakes they are.

We also could build a modern Saturn V with better metallurgy, and computers very easily. I think the reason we don't is that the design is public domain and the usual contractors can't charge 10 times what it is worth.

So there!

Re:Why bother?

[Anonymous Coward]

Thus speaks someone who as never seen a launch and believes things like the Hubble telescope shouldn't be serviced.

As for Russia, they'd hardly go broken when they could put satellites in orbit for under $1m. Materials are cheap, labor more so under the Soviets.

Re:Why bother?

[0123456]

Thus speaks someone who as never seen a launch and believes things like the Hubble telescope shouldn't be serviced.

But no telescope since Hubble has been designed for manned servicing because it's proven cheaper to launch a new one than to send astronauts there.

Servicing Hubble made sense when a shuttle flight was supposed to cost $10,000,000 (maybe $50,000,000 in today's money), but not now it's proven to cost over $1,000,000,000.

Re:Why bother?

[Anonymous Coward]

Yes and no!
The Russians was more intelligent.
If NASA used the BURAN design im everything can be more useful .
The main thing about Buran. HE DONT HAVE main ENGINES like nasa ones.
This make sense. When NASA use the main angines just because do a project from something can go up and back alone for a kind of FRANKSTEIN that need rockets to help go up.
The Buran have a single Rocket do it. Since NASA and Buran ones when come back, do it same way, like a PLANE. The nasa view point become what we have today. A BRICK that go to space. Spend a lot of money just to put in orbit a BIG MAIN ENGINE.
Another concept Buran is more smart from nasa, are the way they used the carbon shields, In nasa they are side y side, with gaps. The buran one are like FISH SCAMS. Doing more chepo to maintain.
Is a pity Russia broke. Or today we can have the Buran still doing the work by a fraction of NASA Shutle.
Sometimes to copy a design can be good to, not bad.

Re:Why bother?

[Y-Crate]

Oh, not the whole "Start Building the Saturn V Again!" argument.

I understand it. I do. On the surface, it makes perfect sense.

But it doesn't make sense from a practical standpoint. All the parts that went into it are out of production. You might find some screws or maybe even some tubing that have lingered on to fill the need of some obscure sub-market, but other than that, it's all gone. You'd have to create production lines for every last part. And production lines for every part that goes into every larger part. Certify all of the components and the facilities where they are made.

On top of that you'd be rejecting any and all advances made in rocketry in the last 40 years. Sure, we haven't made massive leaps like we did from the V2 to the Saturn V in half the time, but things have progressed.

The Saturn V is dead. It will remain so. The time to reactivate the program was during the Nixon administration, and it was probably going to be a challenge as early as the Gerald Ford years.

Re:Why bother?

[eln]

To be fair, if the Buran design is superior it's likely because they started with the shuttle design and improved on it, whereas the shuttle was designed from the ground up. The Russians were (and are) clearly very good at designing space vehicles, but it's a lot easier to come up with a better design if you start with the design your opponent already came up with.

Re:Why bother?

[Anonymous Coward]

>We also could build a modern Saturn V with better metallurgy, and computers very easily.

You could also create a modern rocket with the same costs. There's no reason to revive 60s technology and the cost savings of doing so are borderline non-existent and you have the liability and cost of using 50 year old tech.

Not to mention that LEO is yesterday's problem and is solved using technology being built by private companies like SpaceX. Why spend 100 billion dollars on some new system just to hop to the ISS? Use SpaceX and be done with it.

NASA will probably use the DeltaIV or the Atlas V heavies for their next rocket, instead of building a new costly rocket anyway. Unless Congressmen who want to bring the pork home get their way and force NASA to build a new rocket, which seems likely especially after GOP gains.

Re:Why bother?

[Anonymous Coward]

And how would they know that if they haven't tried it? Paper pushers made numbers look good. Reality made numbers look bad. Reality is where space shuttle flies.

There is nothing comparable to the Hubble. People like you, doing nothing but paper pushing, can't even grasp the numbers never mind the science.

http://en.wikipedia.org/wiki/Hubble_telescope

"From its original total cost estimate of about US$400 million, the telescope had by now cost over $2.5 billion to construct. Hubble's cumulative costs up to this day are estimated to be several times higher still, with US expenditure estimated at between $4.5 and $6 billion, and Europe's financial contribution at €593 million (1999 estimate)." - reason? fuckups.

The mirror was not correct shape too. Reason? Another human fuckup. "The Allen Commission found that the main null corrector, a device used to measure the exact shape of the mirror, had been incorrectly assembled—one lens was wrongly spaced by 1.3 mm.[54] During the polishing of the mirror, Perkin-Elmer had analyzed its surface with two other null correctors, both of which correctly indicated that the mirror was suffering from spherical aberration. The company ignored these test results as it believed that the two null correctors were less accurate than the primary device that was reporting that the mirror was perfectly figured.[55]"

So, thanks to the Shuttle, it was fixed. No shuttle, Hubble is not very useful.

result: http://en.wikipedia.org/wiki/File:Improvement_in_Hubble_images_after_SMM1.jpg

And Hubble is productive since 1990 to 2010+ - 20 year life!

The service missions and ISS assembly are themselves important to understand how to do work in space. Prior to ISS and Hubble, no long space walks were necessary.

But then why bother arguing with someone like yourself. Someone that is against knowledge, but all for spending $1,000,000,000 per day in Iraq during height of the invasion..

Re:Why bother?

Don't forget the fact that Buran also had a working autonomous guidance system and was able to perform an entire mission unmanned.

To be fair, the shuttle could do that with some rewiring (e.g. the landing gear isn't connected to the computers) and reprogramming (e.g. to lower the landing gear before landing). It already flies the majority of the trajectory on most flights by itself.

That said, if they'd tried that on the first shuttle flight it would probably have burned up due to incorrect assumptions in the aerodynamic model that required John Young to fly manually for part of the reentry.

Re:Why bother?

But no telescope since Hubble has been designed for manned servicing because it's proven cheaper to launch a new one than to send astronauts there.

If that were true, Hubble would never ever have been serviced, as it would be "cheaper to launch a new one". And yet it has been, repeatedly. Not only to fix the original mirror defect, but to install whole new equipment (like the ACS).

[Un pobre guey]

Will you just stop? You are either deliberately misleading or didn't quite get the post. Hubble was designed to be serviced by the shuttle. The ulterior purpose was to justify the shuttle program and, more specifically, the budgetary outlays for it. Had the Hubble been designed to be machine-serviceable, it would have been much cheaper overall. That's the point the parent was making. Nobody is criticizing the Hubble. It was and is certainly a great piece of hardware that, unlike most NASA boondoggles (e.g.ISS), actually produced both an enormous amount of scientifically useful data and a grand collection of beautiful and inspiring images.

The corrupt military-congressional-industrial complex of which NASA is but a part is determined to spend as much money as is humanly possible in order to maximize the amount they manage to skim off.

NASA Shutle is incredible, besides they kill the original project.
Buran, same being a AERODYNAMIC copy, and a lot of other systems copy is amazing to.
But besides be a copy. Buran do have more in original concepts of shutle than the own nasa shutle.
and they develop some techonology that already still ahead for nasa today.
Maybe if and AFTER the Buran, the new Shutles do copy some ideas from Buran ( like buran copy nasa).
Today we still do have a shutle.
The most important from all. The russian, do have a ROCKET capable of put BURAN, PAYLOAD, and the own rocket in space.
This was one of most important point about all thing of CONSTALATION, NEW ROCKET.
Its what russians already do.
Both NASA and Russia, do a good job, When the politics/military come one.
The lost here. IS.
There 2 technology forks, from the same basic design ( The buran and the nasa shutle), Copy or not and both one doing another better in some way, are lost. ( of course we learn a lot and use this learn in lot of things).
Today we are coming back to old idea of big managed capsules ( the nasa one will never be done, the X project heavy cargo, the esa/russian ones, the japanese one and china). all are the same.

Everything come to basic concept about what was suppose to be the shutle.
In this point.
Technology, cost, manageability and usability. Buran was more closed to this original project. BEING or not a COPY.
About the SHUTLE PROJECT by all.
The most important here are the launchers. There is the point. Buran by own is just a reusable big container well donne.
Shutle do have engines and all kind of sensible technology inside that put more to trouble and be more expensive.
Buran was to be sold for anyone want to pay, and was cheap. no one buy. Just because THE AERODYNAMICS by itself, today is well know. the afterwards inside are almost nothing.
Same the Shutle. Anyone can buy one ( nasa put to sold, all shutles, already, and is cheap). But can do nothing because of level of complexity.

Same time we lose we win with shutles/buran.
The pity is an era end. And not a news one in horizon.

Re:Why bother?

[tibit]

With projects like that, you won't know the risk until you try. A couple times. So even though the risk has a cost, there's no way to tell what cost it has. There are highly paid IMHO clowns who pretend to be able to put a price to such risk, but it's a mere pretense. They are very poor predictors of any individual project's risk, they can only gauge risk in bulk, across several unrelated projects. IOW, they know a lot about everything, but nothing about something in particular. So whatever risk they come up with has only to do with a nonexistent aggregate. It's like with curving grades: individual students get efd up even though on average things look peachy; said average usually is unrealized, too.

As for the cost of relaunching Hubble with ACS: last time I checked, it could have even been cheaper than a Shuttle service mission if you take into account indirect costs. Politics at work. If Hubble somehow got serviced using other means (say Soyuz spacewalk, or a replacement mission), people would scream bloody murder that it wasn't the Shuttle that was used to service it. Even so the last service mission almost didn't happen.

There's no conspiracy theory to that, just plain good old politics at work. Daily Washington life, if you will.

The shuttle was an misconceived expensive piece of junk designed to make the Russians go broke copying it. (Read Buran). We should have never given up on the Saturn V as out heavy lift platform.

Had we kept Saturn V's, they'd be just as expensive, if not more expensive, as the Shuttle. They need much more infrastructure (in the form of the manufacturing facilities) and many more man hours to prepare for flight - and are only worth flying when a multi-billion dollar payload is ready.
 
The problem is... there just aren't that many multi-billion dollar payloads to be had.*
 

We also could build a modern Saturn V with better metallurgy, and computers very easily. I think the reason we don't is that the design is public domain and the usual contractors can't charge 10 times what it is worth.

See above. The reason we haven't tried to build a modern Saturn V is simply that there is no need for one. Nowadays, it's *much* cheaper to buy multiple launches on one of the bigger Atlas' or Deltas and assemble on orbit. (Not that building an umaintainable space station like MIR, or like ISS is going to be once Shuttle stops flying, is a good idea to start with...)

How is developing and certifying new production lines for Saturn V parts any different than the original proposal to develop and certify production lines for a new heavy lift rocket like the constellation? It would seem to me to be the same cost with the one exception being that having produced the other parts at some point previously there should be some record of the challenges and common problems that had to be overcome which would make it slightly easier to restart production than from scratch.

That's just my two cents but I would be interested to hear otherwise.

The Problem Casuing the Delay

[BJ_Covert_Action]

This article contains some more specifics regarding the problem. Apparently one of the main engine controller computers (the computers that regulate main engine gimbaling and throttle control) failed to power up properly. There was a short time period where a low-voltage occurred which flagged a boot-up sequence issue. Engineers are trying to figure out what caused the voltage drop and, thus, triggered the error in the processor initialization. More information regarding the SSME controllers can be found here.

Apparently the breaker that controls the processor was cycled five times over night. Engineers are guessing that the cycling caused some funny transient anomalies in the circuit which caused the fault. Despite the fault, the main events controller for the shuttle system was brought to full power and is operating nominally, so it's not like the whole computer is crap. NASA just wants to be sure that, a) the fault was actually caused by the breaker cycling and b) the fault won't cause further glitches in any of the other controller systems on the shuttle.

Interesting stuff indeed. It's probably a good thing that NASA is demanding certainty from it's engineers before clearing Discovery for launch.

And part of the reason I don't trust private sector space exploration at this stage of space exploration..

Any private launch company who killed its passengers one time in fifty would be out of business very fast. As far as I remember Branson is planning over a hundred test flights before putting passengers on SS2.

And the main reason this is an issue is because a failure which caused an engine shutdown early in the flight would require an RTLS abort which is probably unsurvivable, and a failure later in the launch would require an ATO abort which would prevent them from getting to ISS.

Re:The Problem Casuing the Delay

[Thud457]

Technically correct, most computer problems are at one level, electrical problems.

I'll have to remember that one for the excuse list...

Re:The Problem Casuing the Delay

[BJ_Covert_Action]

Well, believe it or not, the type of data that reflects this particular fault would need to be gathered just to allow the engine controllers to function properly. In other words, the redundancy that is built into such a two channel system is in-built so that both processors can check one another in order to have one more reference input to their feedback loop. If I have controller 1's best estimate of the current system state, and I have controller 2's best estimate of the system state, and I have a third estimate of the system state uploaded to the launch vehicle through telemetry resources based on observed flight characteristics, then then I have three system states that I can compare against one another in order to develop and process a command set for the next clock cycle. This type of three-state estimation is pretty much necessary just to damp your transient responses in any highly dynamic system within a reasonable amount of time. Without such a system, your controller often cannot damp out the transient responses for any given state variable and your system decays into an unstable (exploding) mode. In other words, no steady state is achieved.

That said, in order to achieve stable flight (something already demonstrated by the space tourism industry with SS2, Falcon 1 and Falcon 9), the space tourism industry is going to have to have these checks inbuilt on their systems. They wouldn't be able to fly without them (in fact, considering the complicated geometry for SS2, I would be extraordinarily shocked if they could achieve any stable flight without at least 4 redundant state readings). Ergo, this type of pedantry is a necessity in order to have a functioning vehicle. Thus, the likelihood of the space tourism industry killing customers by skimping on these kinds of checks seems highly unlikely, if not entirely impossible, by the very nature of designing a controllable, complicated launch vehicle. Now, don't get me wrong, the space tourism industry (and NASA) very well could kill customers by various other means. I just don't think a problem like this would be the likely cause based on little more than my own experience in designing flight controller systems (as well as an undergraduate degree focused on that subject).

Of course, you might just be trying to say that, while NASA is willing to slip a launch and miss a launch window in the name of certainty, the space tourism industry might not. Many 'dotters probably feel that an industrial launch industry would say, "Waiting a day will cost us X many dollars in profits, launch anyways!" (kind of like NASA did with Challenger). Personally, I also find this highly unlikely as dead customers don't tend to be able to spend more money on your company. If Branson blows somebody up, he can't count on them to fly a second time. Combining that with the fact that any engineers involved in such a company would promptly quit (because no engineer wants a customer's death on their conscience, trust me on that), and the company would then undergo a brutal brain drain and a period of stagnation, leads me to conclude that no entrepreneur (especially one that intends to fly on his own hardware) would be willing to take that chance. As you seem to imply, companies want, more than anything else, to protect their profit. Anyone getting involved in the commercial space industry that is flying hardware would not be so dull as to think that killing their customers will increase their profits.

Saying, "Hey look, my company is flying people into space every week!" is awesome and generates a sense of pride.

Saying, "Hey look, my company has only killed five people in the last five years!" brings on epic levels of shame and thoughts of suicide.

That is just my $0.02 on the matter though.

Re:The Problem Casuing the Delay

Private sector is already sending almost every thing we launch into orbit.

Take the United Launch Alliance (Boeing/Lockheed Martin joint venture) with, I believe 4 Atlas launches and 4 Delta launches just this year. Take Orbital Sciences Corporation with Taurus II (I believe). Orbital spinned off a company called ORBIMAGE, now GeoEye, that provides a significant part of the beautiful imagery you see in Google Earth. Arianespace has part of its capital in the hand of private investors too, I believe (if EADS is a private company - I'm not certain of that).

Private space companies are not going to happen. It already happened a couple of years ago.

Re:The Problem Casuing the Delay

During my spacecraft design class, my team used to complain that we should just higher a bunch of electrical engineers to design our satellites since that's what it seemed like everything boiled down to. When we came back from Christmas break after our first quarter together, the administration had tried to re-image all of our workstation computers, rendering 90% of them unusable. When the IT maintenance guy was in our lab one day, my team lead asked him why it was taking so long to get the computers working again. When he mumbled something about the wrong image being used for the wrong systems, I irreverently shouted out, "Find an electrical engineer to fix it!" which brought a chuckle from the class.

Three days later an EE student was in the lab to talk something over with one of his aero friends and he sat down at one of the non-working computer consoles without anyone noticing. Three hours later, I walked by and realized he had the system up and running. I couldn't help but snicker.

Not to mention Boeing and Lockheed Martin's other joint venture, United Space Alliance took over almost all of the logistics of the Shuttle program about 4 years ago. NASA provides the crew and vehicles, USA does most of the rest.

Re:The Problem Casuing the Delay

[Animats]

require an RTLS abort which is probably unsurvivable

It's certainly untried. There's never been a successful post-launch Shuttle abort. On three occasions, there have been shutdowns on the pad after engine start. STS-51F did an abort to orbit after an unexpected shutdown of one main engine. But that's a near-normal flight diverted to a lower orbit. The Challenger disaster was the closest to a situation when an RTLS might have been attempted, but the vehicle damage was too great to even try.

It's probably a good thing that NASA is demanding certainty from it's engineers before clearing Discovery for launch.

It's not such a good thing that Slashdot isn't demanding correctness from its pronouns before clearing posts for display.

Re:The Problem Casuing the Delay

[Anonymous Coward]

Not true at all, keep in mind astronauts are NOT "passengers". They are employees. You can't build large tunnel projects, skyscrapers, mines, or bridges without having some accidents that cause loss of life. Space exploration would probably be considered even more deadly than all these fields and the employees would understand this risk (and sign contracts/waivers that say they understand).

Re:The Problem Casuing the Delay

[GodfatherofSoul]

Yeah, but if the "dead passengers are bad for business" motif was true, we wouldn't have an NTSB and an FAA. And, car manufacturers like Toyota wouldn't be getting caught playing cost analysis games when their products are found to be defective.

Re:The Problem Casuing the Delay

[hawkfish]

And part of the reason I don't trust private sector space exploration at this stage of space exploration..

Any private launch company who killed its passengers one time in fifty would be out of business very fast. As far as I remember Branson is planning over a hundred test flights before putting passengers on SS2.

This seems to imply that NASA did little to no testing of the Shuttle before putting humans aboard. This is simply not true. I once saw a list of all the pre flight testing that was done and it was quite substantial.

I'd also like to know how a private company can get the MTBF up so high in such a dangerous environment without either killing customers or burning through an obscene amount of cash.

Re:The Problem Casuing the Delay

[TheStatsMan]

It's pretty easy to rationalize something as low as 5 deaths per year. Many corporations are responsible for many more deaths than that. Granted they are not obvious "zomg-died-in-space" deaths.
Solution: outsource space exploration to Mars.

Re:The Problem Casuing the Delay

[BJ_Covert_Action]

Toyota found to be playing cost analysis games when their products are defective? Hmmm, last I heard, the unintended acceleration cases were primarily overblown: see here. Also, I am not entirely sure what your point is with regards to the FAA and NTSB. Both agencies are setup to help regulate both the logistics and safety concerns regarding modern transportation, which, incidentally, also includes regulating space tourism: see here. The reason some regulation is needed is not because every company that has access to a particular technology will abuse it at the expense of its customers. The reason regulation is needed is because in any industry there will be a lot of quackery products right alongside viable products. So, while Virgin or SpaceX might establish a safe and healthy space tourism industry because they need continued revenue from customers, another company might come along, make some, "too good to be true," claims about cheap access to space, charge it's first set of customers for a ride, kill them, and run off with their money. Regulation helps establish a barrier of entry at a particular point that balances the need to prevent a monopoly with the need to prevent fraud. This is a good and necessary thing.

If you are under the impression that any and all companies will hurt their customers simply to make a buck, you are quite mistaken. While there is no shortage of examples of this happening, there are also quite a few companies that genuinely do attempt to provide good, safe products. Some that come to mind are Trader Joe's groceries, Maytag appliances, Cessna, and Bobrick. It's easy to think that companies and corporations are out to do nothing more than screw their customers because that's all we see in the news about companies and corporations. But what a lot of us fail to realize is that for every scandal story involving a single company, there are probably a dozen other small, medium, and even large companies that don't make the nightly report because they don't screw their customers. Thus, we get inundated with a very single-sided view of business.

So I guess what I am getting at is that, while there are companies that have killed people in the past (due, more often, to accident rather than negligence), there are also a lot of companies that haven't. Thus, immediately jumping to the conclusion that a new industry, filled with new players, is going to skimp on safety in order to save a buck is nothing more than bias. As it stands now, we don't have enough data to determine whether or not Virgin, SpaceX, Bigelow, Masten, or anyone else is going to kill their customers. My default assumption as an engineer is that they won't because, well, their engineers get paid not to. Supposing someone does die in a crash eventually (and eventually someone will, I have no doubt about that), I will wager that occurs due to some unforeseeable accident (which does happen because even the most intelligent engineers and scientists are not precognitive) rather than some terrible negligence or intentional flaunting of safety regulations on a company's part. As the space tourism industry stands right now, it is employing some of the most talented engineers in the field, and it is under extreme scrutiny by existing players (NASA and the FAA, not to mention various congressional financing committees), thus, I think jumping to the conclusion that any players in the industry will skimp on safety is fairly unfounded cynicism.

[Anonymous Coward]

I think it's even safe to say that the Shuttle have no abort system. A Shuttle must be safely flyable to perform any of those abort sequence, which means there's no critical problems in the first place to continue a flight. There's also time-consuming post landing safety procedure even if it could safely land to ground. Any other manned spacecraft(save for Buran) require just capsule and ejection rocket, maybe less than 10% of the entire vehicle to be sane for a safe abort.

Imagine how an RTLS will go like. 180 half-loop in upper atmosphere on a half-broken aircraft? No, thanks.
