Nasa Put Wrong Landing Gears On Space Shuttle

How NASA are idiot and never have inspections check up after passed? It's unbelievable stupid engineerings and workers.

Read that news:

Yea. Pretty Stupid engineering. They only sent a frickin rocket into orbit, but they are stupid. Woulda been a whole lot better to say "Wow, thats a big mistake".

I personally think the SS is an engineering marvel. Anybody who can send a man into space and orbit the Earth is ok in my book.

First, the problem was not with the landing gear per se. It was with gears that controlled the shuttle's braking mechanism. And I think it was only one set of them that had been installed incorrectly, but I could be wrong on that.

Besides, my understanding of this issue is that it was likely to crop up under circumstances similar to an aborted launch/return to Kennedy. And if you think there's a good chance of the shuttle surviving that -- faulty gears or not -- well, I have some oceanfront property in Arizona you might want to take a look at.

OK, NASA has made some huge mistakes in the past, but I think it's pretty ridiculous to characterize the engineers and workers as unbelievably stupid because of this incident. It was a dumb mistake, and certainly should have been caught, but it isn't indicative of institutional stupidity. If you're going to apply that blanket characterization, at least make it for an incident where they deserve condemnation -- the truly idiotic decision to launch Challenger is one of them (and of course, all the engineers warned vehemently against that.)

You seem to forget about all of NASA's incredible triumphs, things that wouldn't have been possible without a few smart people working there. No one should have to be reminded of them, but here are a few: Apollo, the Hubble, Mars Pathfinder, Voyager I and II, Pioneer, Skylab ... I can go on if you like.

Bottom line: NASA needs to change, but dumb engineers are the least of their worries.

This article doesn't have anything to do with landing gears.

What it is about, are the gears in the RUDDER, used to deploy the speedbrake upon landing.

RTFA. This is the worst topic headline exaggeration I've ever seen here, and you people get mad @ journos when they make an engine out seem like life or death......... unreal.

Indeed, following on from the previous post, the problem with the Shuttle is something called the 'Rudder Speedbrake Actuators'.

Unfortunately, there were two distinct problems found -
1 - Corrosion on the actuators
2 - In one case a gear had been installed upside down

Using spare parts and getting some new ones manufactured by Hamilton Sundstrand shouldn't push the next scheduled Shuttle flight back from March 2005 as is currently forecast.

It IS an engineering marvel, but probably not such a good idea. Personally, I think the Space Shuttle was a costly one way trip to nowhere.

- Cheap access to space: throwaways are cheaper.
- Reliable access to space: throwaways are more reliable.
- Evolutionary approach: oh, so what's why we are going back to throwaways.

Seriously, I'm all for the Shuttle as the original concept went, but unfortunately the STS was hampered by having to do 2 things at once. The whole thing started out as a space taxi for 5-7 people and no cargo. But the payload capacity kept being increased as the Roger Ramjets at NASA upped the requirement to "should replace everything and the kitchen sink". Result: Overweight. Solution (and this is where the insanity comes in): add two solid rockets, something that engineers on man rated craft have always previously shied away from for obvious reasons. While the SRBs are lit, there is NO way to escape in case of a malfunction. Hmmmmm, nice one. So your reliability is abysmal and it's unsafe. (For more info on the development of the Space Shuttle: I quote: In the final analysis the shuttle came up short in two areas. First, the shuttle orbiter ended up almost 20% over its specified weight - resulting in it being unable to boost the US Air Force’s payloads into polar orbits from Vandenberg. Lighter filament-would casing Solid Rocket Boosters were being developed for use in flights from Vandenberg, but even this did not seem enough. After the Challenger explosion the USAF was able to extricate itself from the Shuttle program. The Vandenberg launch complex, built at the cost of billions, was mothballed. The Air Force started a new costly development program to design the Titan 4 expendable rocket for its large military payloads. The second was that it failed, by most definitions, to reduce the cost of putting payloads into orbit. The shuttle program inherited from Apollo huge fixed costs - the Manned Spaceflight Center in Houston, the cadres of government and contractor workers at the Kennedy Space Center, and so on. The result was that there is a fixed base cost of around $ 2.8 billion per year, just to keep all those people and facilities in place, even if you don’t conduct any flights at all (as occurred after the shuttle disaster). The marginal cost of each flight added to this base is under $ 100 million per year. Seen this way the shuttle is almost competitive expendable boosters - but doesn’t come anywhere near the reductions NASA promised when development started. But if you divide the usual number of flights per year by the total costs, you come up with a figure of $ 245 million per year, significantly more than a Titan 4 or Proton launch with the same payload. )

Ironically, the Air Force and NASA had already developed a shuttle in the early 60's, known as Dynasoar. It would have been cheaper and more reliable, and would have flown almost 20 years before the shuttle. ***SIGH*** (For more info on Dynasoar:

After Challenger, NASA figured out that they couldn't replace everything with the shuttle. It was too expensive and too unreliable. So what came back: The throwaway. Which by now was cheap and worked like clockwork (see here for the Delta rocket record:, not bad for a non manrated booster).

And now, after 20 years of iffy, very costly Shuttle ops that have made little improvement on Apollo, what does NASA want? A capsule that would maybe be reusable, but will be sent up on throwaways. Go figure.

Just my €0.02.

EDIT: My friend chatted me. He predicts it will be less than 10 replies before this thread turns into a "Why do you hate the US?" bashfest. Big grin

Yea - this one is going nowhere fast.
