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.

Look people, why are arguing (well some ) over a test of a hatch? grow up !

@das7282 stupid dumb world wide web had be create by CERN at geneve ... stop smoke grass stupid fools

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..

When you learn to spell argument come back and call me a child. Also, I'm mature, nothing I've done has indicated otherwise.

[jonnypyro]

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

[mankywank]

If that's your most constructive argument then you're the child. Also, I'm 18 so by definition I'm an adult.

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.

They got a few computers hooked up together. Big whoopsie. No wonder they never patented it.

[MrM0j0Risin666]

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.
