...and it would have failed, most likely. You don't want anything that may become stuck out there, unless you're there to kick it (which you are *not*).
The inside of the telescope is a vacuum to keep the instruments cold and prevent contamination during assembly. Using a hinged door mechanism which opens outwards prevents the door from opening when the pressure outside the telescope is greater than the pressure inside;. so a door can only be opened once safely in the vacuum of space.
A sliding mechanism can be opened regardless of pressure inside and outside of the telescope, so if opened too early air could enter and ruin the mission.
That would make sense but apparently the insides of the telescope had to be guarded against residues of gases & contaminants whilst actually in empty space over a long period of time. So what you are basically saying is that the pressure differential issue applied at liftoff but not particularly long after that.
Bottom line ... the design worked .... up there very far away. Getting it to work first time is paramount. Imagine the design engineering team's relief. A great success and we'll all get to benefit from it.
Now, the design argunments on this thread are all great ...they are important and all the better for future designs ... "No such thing as a dumb question ... there IS such a think as a dumb answer however.
Thanks to those on topic ... sadly there is always too much off topic !!!
Actually the hatch door is a good low risk of failure design. The latch releases the hatch door that is on a spring. Simple mechanics but works. Using motors and circuitry add more complications and risk of failure is increased. The hatch opening once the latch was released was almost a dead cert and succeeding. The hatch was just bouncing on it's sprung loaded hinge would come to rest in the open position. Without the hatch open the telescope would be about as useful as tits on a bull.
Precisely, that is what I thought. The spring is supposed to be quite weak compared to the inertia of the hatch, that's OK, we don'ŧ want to shake the whole thing like mad. The friction damping could be higher, but I also see nothing out outright wrong with it - what if it were too high for any reason and the thing didn't move at all?
Was I referring to you or are you paranoid or just sensitive? you seem to attract negative responses as I can gather from your page. 'a pointless collecton of meanignless rubbish - if you came here for any reason you have been misled' says it all really...
Who cares who invented what? In this day and age our similarities are far outweigh our differences. The exploration of space as a species underlines that.
i wonder , scince this is a infa-red telescope will it show us what really is at the coodanance 13h 48m 0s -- -8degee's 24' 25", it is blocked from view by most country's
Right, so this is where I point out how you improperly used the English word gyroscope by shortening it into slang gyro. Now according to your colleagues methodology, I will proceed to label most British as idiots for you having used a variation on the English language.
I suppose you were also taught that the US captured the fiirst enigma machine and that NASA invented velcro etc etc. It is well known that US schools do not teach fact, preffering to make things look as if the US was the good party. The first concentration camps were "discovered" by British survelillence planes. Russia liberated the first camp on the 24th July 1944. The first camp liberated by the yanks was on the 11th April 1945. Look it all up on the internet.
To add to that. the US is also taught that E=MC2 is not correct, Newtons laws of motion are wrong and the US has its own version of the periodic table. Fascinating stuff. You can find it under the reference "complete idiots" section of the new Clinton library and soon in the Bush library. Its of note that the Bush library will provide evidence that the Native American Indians were terrorist and attacked when the first pioneers claimed the country as there new home.
newtons law start to be noticeably wrong at around half the speed of light. since we haven't reached those speeds yet, newton mechanics are still right in almost everyday life.
Both laws are quite familiar to me, however non explain facts given. A particle at rest or in motion behaves in a predictable mathematical model as you described above, it does not disappear, "Special relativity" expands on newtons basic laws of gravity, it does not negate them. As for the periodic table? well thats a question everyone ignores..
Hmmm?? The US military invented the internet which is an indisputable fact. Tim Berners-Lee was British but he was at MIT (a US university) when he invented the World Wide Web... So where does Europe fit into the equation?
The Internet was a US invention, yes; but you're incorrect about the World Wide Web, which is generally accepted to have been "invented" whilst Tim Berners-Lee was working in CERN (France/Switzerland), not whilst at MIT :s
Without gyros,neither america would not be in space or flying t planes ,missiles or guiding their ships around the world...Start there...a simple mechanical instrument..,stabilizes all, without it and it's mechanical orientation ,no plane ,no missile would reach it's target,no ship or specifically submarine would know where they*re at and no spacecraft could be launched ,nor sighted towards the universe....invented 200 years ago...not in America
Umm...what? Okay, all the inventions coming out of Europe and the end-all invention to this conversation that you come up with is the Gyro? Neat, I guess this is where I will say that the US invented slurpees and then we can call it a tie.
There are very large springs on the lid that are keeping it open. I think that explains the violent recoil it had, those springs forced the hatch open and will keep it against the back supports.
I think you shot yourself in the head with the first sentance you wrote. Do not every equalise domination with positive attributes. Thats a dangerous, false and narrow-minded assumption.
'utilizing the internet, an American invention' - just lol at that one - what u see in front of you today aint anythin that the US invented - it took someone else (Berners-Lee) to put it to practicality. In other terms, you may invent the wheel but that doesnt mean youve invented the bicycle.

Stop discussing the stupidity of Americans, it's a cultural thing to have pride in the inaccuracy of language. Yeah I think it's annoying, but in the grand scheme of things it doesn't matter and it doesn't reflect intelligence.
It also seems the loudest are the most stupid, as with all groups of people, it just happens there are more people in America.
I'm not insulting Americans, I'm just saying that there pretty much is more freedom in how they choose to speak.
Example:
"I'm doing good" would be "I'm well" because literally "doing good" means they are undertaking activities which are good. We interpret it is "I'm well" but it's inaccurate.
Well, I'm one American who truly appreciates what Herschel (and Planck) will do for Astronomy. Bravo ESA, bravo! Though I am curious about something - the mass of the hatch must be fairly high by the amount it bounces (and shakes the hull), does that need to be dampened by gyros or thrusters once it's opened? Seems like it would cause a lot of unnecessary and unwanted vibration in the spacecraft.
I know what you mean Bry850, I think this is the first comment I've ever made here on youtube.
And it's all about a stupid video... I was just trying to clarify to many watchers that this isn't the actual footage of the Herschel Space Observatory as the title suggests.

Bugsize, that was meant to be a reply to st1cklebr1ck, whose comment regarding the moon landing made no sense. Mine posted as a new comment however. Glad you can tell I'm American based on YOUR perceived lack of context :) As far as your blabbering is concerned: yes it is test footage, not the real deal. Yes the headline is misleading. Go pat yourself on the back.
Explosions are cooler. What would have been even cooler would have been a robot who would have pushed the door open - is R2D2 available - he is French right?
There are allot of dis informants who are trying to make you think this is the actual footage of the Herschel Space Observatory hatch opening, as the video title and video comment suggests.
It's not the actual Herschel Space Observatory that is out in space.
I suppose this is a great big conspiracy to get people to think that we've managed to put a telescope in space, but really it is shot by the same people that "faked" the moon landings. That way the evil scientists will pretend to look at the dawn of the universe in order to brain wash the publc to... blah blah blah.
uhh yeah, i guess they fooled us in 1990 with Hubble, oh and have you heard of Sputnik? Do you believe nothing has gone into space or do your theories only apply to telescopes? When you put "faked" in quotation marks it A) seems you don't believe that they were faked (you know sarcasm doesn't work written in comments) or B) you... blah blah blah.
Yeah sure, it's all a big giant conspiracy and everyone's involved except you. Oh yeah, that conspiracy about the world not being round must be true too. It's really flat, and we're all pawns in this big game of hidden facts. Every time someone gets smart and acquires a degree in Astrophysics, Quantum Physics or friggin' Rocket Science they're just trained to be liars, not scientists who actually discover how to bend the rules of physics.

This was not filmed in space! This video is fake.

What simulation... this was launched in may and as the comment sais; "the lid release mechanism on the Herschel Space Observatory. Video courtesy of Herschel scientists and ESA. "
Where is there any implication that this is in space? I would not expect a video from space. I would not expect the telescope would have a video camera and lighting to record the opening of the hatch in space. The video was no doubt shot during a test in the lab on earth.
60% of Nasa's overt budget is military. God knows how much is covert. I'm no big fan of the bureaucrat scientists in their cush jobs, but this is far better than all the money the US wastes on Romanesque conquest and domination.
That was one small lid release for a man, one great lid release for mankind. I can't wait for the pictures. This research is the best investment for our future. We need more telescopes up in space.
The bit that costs the money is the rocket, the security measures, the rules to prevent contamination, the designs to reduce weight, the incredibly expensive lenses, the list continues,
age is just a number. your maturity level is what truly defines you as an adult, not what a countries definition of adult age. by your arguement you are still the child
Oh be quiet. Firstly, 26% of the American budget goes on the Iraq war. A HUGE percentage of the worlds budget has gone on saving us from a global recession. 1% of the Americans budget goes on NASA. If you want to point the blame somewhere, point it at the banks, the politicians and most importantly the people who lied about WMDs in Iraq.

How fucking lame. For you bush is behind everything, I bet you keep blaming bush because you still live with your mom, don't have a job and your g/f ran away. Boring!!
The use of springs was far simpler, more reliable (and lighter) than the use of servos. The bouncing of the lid was detected by the craft's accelerometers as a successful opening event. I think the lid's design was superbly based on the KISS principle... and common sense...
Why don't they use a slide lid? Or, why is there no mechanism to keep the lid locked so that it won't bounce back? What if the lid falls back half way, which will block some of the light from the telescope?
i meant zero-gravity. just a quick translation error, and suddently the spelling police and qiuck judges are all over you.. jeez.. its a comment, not a forum. discuss the matter at hand, and let "peronal" matters be.
This is a spare they have on earth that was kept shut at cryogenic temperatures (and in a vacuum I imagine) for two years, just so they could test the mechanism.
For a lid that was safely closed against atmosphere leaks for two years, and at an atmosphere differential at times, it was a robust opening. These things stick!
This technique was probably chosen because it was the most reliable and robust. It would have been sealed very well for the launch and so using pistons or a mechanical bolt may not have had the force to open the lid. Also, there have been many problems in past where parts shift during launch and cause the mechanics to seize up. Using brute force on millions of dollars worth of equipment is sometimes the only way no matter how precisely it is engineered

Brute for on millions of dollars worth of equipment is sometimes the only way precisely it is engineered
Also, it is shown here in slow motion. Therefore it may look flimsy, however shown at this timescale most mechanics do this at high stress levels. You can see the metal warping like this all the time at this timescale and it is factored in to the design, probably... I'm no rocket scientist
I wonder why go to all the trouble of this elaborate release system, but there doesn't seem to be a way to reverse it - what if you want to put the thing back on (to protect instruments from some potential hazard) ? If you never want to put it back on then the release system does seem over the top - why not just hold it with a spring mechanism and put a charge across it to spring it ?
It's bouncing around like it is in zero grav quite impressively. How long will the liquid helium last and what happens to it when the gas finally boils off?
Herschel is expected to remain operational for about three years, which is presumably the timeframe that the machinery will be able to remain usable for.
1) Hubble is in a near earth orbit and is thus servicable
2 ) Hubble is in a stable orbit and doesn't require the constant powered adjustments that Herschel will need in its L2 orbit (if it was released at even a slightly less optimal trajectory when Ariane sent it off, it could take months off of its lifespan)
3) Hubble doesn't require liquid helium to keep its components cool. The He will boil.
If you consider that the Earth orbits the sun as it does because the gravitational attraction of the sun is equal to the centripetal force of the Earth's orbit, the L2 point is a point beyond the Earth where a satellite's centripetal force balances with the gravitational attraction of both the Sun /and/ the Earth. Thus we also find that at this point, a satellite has the same period as the Earth.
For no doubt a better explanation, check Wikipedia.
I'm going to have to have a look at centripetal force. Probably a good thing to keep me thinking physics until I get into university, exam results allowing. Coincedentally I had my last exam today.

There are allot of dis informants who are trying to make you think this is the actual footage of the Herschel Space Observatory hatch opening, as the video title and video comment suggests.
It's not the actual Herschel Space Observatory that is out in space.

Yes. This is standard operating procedure. This is how the solar panels are deployed on satellite.
I would wager that reliability and also weight factor into this.

Nobody is claiming this is the actual event? are you serious? READ THE VIDEO TITLE
Lid Release on the Herschel Space Observatory
It doesn't say simulation, it doesn't say this is what it would look like, it doesn't say this is a test firing etc.. etc..
They are trying to mislead people into thinking this is the actual hatch release from Herschel Space Observatory.

Just because it's a video of the same lid mechanism doesn't mean it's on Herschel. ESA and BBC are both linking to this video as a demonstration.

Where is there any implication that this is in space? I would not expect a video from space. I would not expect the telescope would have a video camera and lighting to record the opening of the hatch in space. The video was no doubt shot during a test in the lab on earth.

The use of springs was far simpler, more reliable (and lighter) than the use of servos. The bouncing of the lid was detected by the craft's accelerometers as a successful opening event. I think the lid's design was superbly based on the KISS principle... and common sense...
technomech 2 years ago
Why don't they use a slide lid? Or, why is there no mechanism to keep the lid locked so that it won't bounce back? What if the lid falls back half way, which will block some of the light from the telescope?

This technique was probably chosen because it was the most reliable and robust. It would have been sealed very well for the launch and so using pistons or a mechanical bolt may not have had the force to open the lid. Also, there have been many problems in past where parts shift during launch and cause the mechanics to seize up. Using brute force on millions of dollars worth of equipment is sometimes the only way no matter how precisely it is engineered

Also, it is shown here in slow motion. Therefore it may look flimsy, however shown at this timescale most mechanics do this at high stress levels. You can see the metal warping like this all the time at this timescale and it is factored in to the design, probably... I'm no rocket scientist

Thank you for your comments Emanuel -
I wonder why go to all the trouble of this elaborate release system, but there doesn't seem to be a way to reverse it - what if you want to put the thing back on (to protect instruments from some potential hazard) ? If you never want to put it back on then the release system does seem over the top - why not just hold it with a spring mechanism and put a charge across it to spring it ?

Hubble was expected to finish operations many years ago.
KapernicusI 2 years ago
True. But:
1) Hubble is in a near earth orbit and is thus servicable
2 ) Hubble is in a stable orbit and doesn't require the constant powered adjustments that Herschel will need in its L2 orbit (if it was released at even a slightly less optimal trajectory when Ariane sent it off, it could take months off of its lifespan)
3) Hubble doesn't require liquid helium to keep its components cool. The He will boil.
esteluk 2 years ago 3
Being a few hundred thousand miles away causes difficulty. I wish I caould find somewhere that explained how L2 works, the BBC was innadecuate.
KapernicusI 2 years ago
If you consider that the Earth orbits the sun as it does because the gravitational attraction of the sun is equal to the centripetal force of the Earth's orbit, the L2 point is a point beyond the Earth where a satellite's centripetal force balances with the gravitational attraction of both the Sun /and/ the Earth. Thus we also find that at this point, a satellite has the same period as the Earth.
For no doubt a better explanation, check Wikipedia.
esteluk 2 years ago
I'm going to have to have a look at centripetal force. Probably a good thing to keep me thinking physics until I get into university, exam results allowing. Coincedentally I had my last exam today.
