View Full Version : Hubble Telescope to die in orbit spook 08-02-2005, 13:47 ........................... Skatiechik 08-02-2005, 14:00 Cheers for the desktop pictures :) Andy78 08-02-2005, 14:06 They're really quite stunning! I'm having trouble deciding which one to use as a desktop. :confused: nick2 08-02-2005, 14:17 Why is the telescope going to "die", it's solar powered isn't it ? Cyclone 08-02-2005, 14:20 I thought that they'd decided to 'de-orbit' it? Skatiechik 08-02-2005, 14:21 Did a quick search on the BBC Website http://news.bbc.co.uk/1/hi/sci/tech/3405249.stm nick2 08-02-2005, 14:22 Isn't leaving a giant telescope orbiting the planet a bit dangerous for anyone who might go up there in the future ? Cyclone 08-02-2005, 14:30 Originally posted by nick2 Isn't leaving a giant telescope orbiting the planet a bit dangerous for anyone who might go up there in the future ? it's not that big compared to the amount of space around. and they do look where they're going. nick2 08-02-2005, 14:38 Originally posted by Cyclone it's not that big compared to the amount of space around. and they do look where they're going. But it is travelling at a thousand miles an hour, you look left, you look right, you look left again - Arrgggghhhh! hit by a telescope. It might not happen like that though. If does seem a huge shame to lose the telescope though. The last thing they should do is point it at the moon and try to spot the flag and lander that got left behind.

I may be wrong, but I'm sure I read somewhere that 'space junk' (old satellites and the like) was getting to the stage where it was becoming a real problem? cgksheff 08-02-2005, 14:53 I think that all junk is mapped by NASA. I also believe that the Hubble's orbit will gradually decay, bringing it back to earth, they say, around 2011. nick2 08-02-2005, 14:56 I supose cobbeling it onto the space station is out of the question ?

That made me laugh, I can just imagine it now :D Cyclone 08-02-2005, 15:23 nick, the problem is that it needs repairing, and a manned mission isn't a NASA priority and a robotic mission has been deemed infeasible. I thought i'd seen something about de-orbiting it. The proposed $16.5 billion NASA budget includes just $93 million for Hubble, far less than would be needed to repair it. Of that amount, $75 million is intended to develop a robotic mission to de-orbit the telescope into the ocean WallBuilder 08-02-2005, 17:19 There is a tremenndous amount of man made things whizzing around in orbit, lots are still in use but then there is plenty that has just become clutter. There's a little known idea called the 'cascade effect' which might happen one day, the idea is that two bits of 'clutter collide and break into several pieces that go flying off at different speeds and trajectories. This then colides with more satelites or clutter and so you get lots of bits flying around these then hit more things..... You get the picture? Every satelite in orbit get's destroyed. Jamie 08-02-2005, 17:59 Can't they bring it back down to earth and use it here? I mean, if no-one else want's it, can I have it please? (would go nicely in the garden shed). cgksheff 08-02-2005, 18:32 Originally posted by Jamie Can't they bring it back down to earth and use it here? I mean, if no-one else want's it, can I have it please? (would go nicely in the garden shed). Don't wish too hard ... it is not beyond the realms of possibility! (Did you say "in" or "on"........ or "where's my shed gone??") Sierra 08-02-2005, 19:00 Yet more pictures from Hubble: http://wires.news.com.au/special/mm/030811-hubble.htm#00-titlepage2 :) Sierra alchresearch 08-02-2005, 20:26 Originally posted by nick2 Isn't leaving a giant telescope orbiting the planet a bit dangerous for anyone who might go up there in the future ? I don't think it's actually in Earth's orbit. It's a stationary object a bit further out, that's why the US government don't want to service it, because the only vehicle they have is the Space Shuttle which is designed more for orbiting the Earth than travelling to other locations. face 08-02-2005, 22:30 I think they are gonna dump it in the pacific. They do this with lots of things (mir too I think). Wont they eventually screw up with one of these and it will be goodbye to some big city?

There's so much space junk you can't imagine... Cyclone 09-02-2005, 08:23 Originally posted by Jamie Can't they bring it back down to earth and use it here? I mean, if no-one else want's it, can I have it please? (would go nicely in the garden shed). they are going to bring it back down, didn't you see my quote. It's certainly not 'stationary' in space, although stationary is rather abstract and would need qualifying against some other object. I'm assuming that de-orbiting it, means bringing it down on a controlled reentry where it will burn up and the remains will crash into the sea somewhere.

I don't see why they can't bring it back down? ... I mean, what goes up, must come back down, right? Can't they bring it back down in little pieces, then screw it all back together once it's back on earth?

It wasn't all put up in 1 go, so it would require multiple trips, and the reason they aren't repairing it is that they've decided a manned mission is too dangerous. If they can't repair it, they definitely can't dismantle it and bring it home. Jamie 09-02-2005, 10:32 Originally posted by Cyclone Firstly, I don't think it's designed to be taken apart.

There's this really fit girl that lives in a flat across the road from me and that hubble telescope would come in really useful *wink* *wink*. nick2 09-02-2005, 10:34 Originally posted by Cyclone the reason they aren't repairing it is that they've decided a manned mission is too dangerous. What a bunch of big-girls-blouses, lend us the shuttle and we'll send a British team to fix it.

Yeah jamie you could peer through it and see her hair follicles close up, tres sexy! As for hubble. It's had a good innings, but time for a better one methinks. The space telescope concept is proven beyond a doubt. The James Webb Space telescope goes into orbit around L2 sometime in 2011 (it's not the same thing as hubble tho') Greenback 09-02-2005, 11:41 Originally posted by Phanerothyme Yeah jamie you could peer through it and see her hair follicles close up, tres sexy!

I heard about something like that on the radio, and apparently it should be able to pick up microwaves from the big bang (and, apparently, it's so sensitive it may even be able to pick up an 'umbilical cord' to the parallel universe from whence we came...) :help: I could just have been dreaming about all this though.

No, although I think I dreamt about that one. The JWST is designed to look at extremely redshifted distant objects using infra-red. Don't know much more about it than that, but its designed to look even farther back in time than Hubble. Greenback 10-02-2005, 15:05 Phew, I'm not going mad.
