Report - Attempt to service Hubble Telescope almost certainly cancelled

Well, I hope they have plans to send up another one. We've seen seen some fantastic images (though computer enhanced) from the Hubble, and I can't wait to see what they would be capable of doing now. Too bad budget cuts will delay such projects probably indefinitely. 🙁
 
I read that either currently, or very soon, we will be able to build huge terrestrial telescopes with the technology to cancel out atmospheric disturbances. So Hubble was basically obsolete anyway, and probably wasn't worth fixing anymore.
 
Man, if we just had the f'ing space shuttles in operation (THERE IS NO REASON WHATSOEVER FOR THEM TO BE GROUNDED, THIS IS THE LOSS RATE THAT WAS EXPECTED WHEN THEY BUILT THEM.) it would be a fairly small undertaking to fix it - but instead, nobody wants to use the shuttles ever again (I fully expect to see the remaining fleet museumized in the next 2 years) and instead comes up with asinine crap like building a robot to go do it.
 
Maybe if they weren't spending 1 Billion dollars a week killl-er, promoting peace they'd have money for projects that fvcking matter.

The James Webb Space Telescope, which is supposed to be the general replacement for the Hubble, is set to launch a few years after Hubble comes down.

I would be interested in knowing where you get that information.
 
oh know i hope they dont cancel the hubble

its one of the greatest things ever made by mankind. these tools surely have the resources to fund it, but why dont they?!?!!!!!

Love live the hubble, hopefually it will stay up

Why would it be worth it to keep fixing it if we can build better telescopes here on earth for a fraction of the price? 😕

they're not very aimable
 
I thought the Bush administration was partying about a new space endeavour towards Mars? NASA's budget seems to have always been thin ever since the Cold War fizzled, so I wouldn't just stick this one onto the current Bush administration alone. (correct me if I'm wrong)

Especially because the humans-on-Mars thing is projected to cost close to a trillion dollars in the next 20 years. Now they're worried about a billion dollar investment to repair and upgrade the Hubble?

From one of Bush's speeches:
Returning to the moon is an important step for our space program. Establishing an extended human presence on the moon could vastly reduce the costs of further space exploration, making possible ever more ambitious missions. Lifting heavy spacecraft and fuel out of the Earth's gravity is expensive. Spacecraft assembled and provisioned on the moon could escape its far lower gravity using far less energy, and thus, far less cost. Also, the moon is home to abundant resources. Its soil contains raw materials that might be harvested and processed into rocket fuel or breathable air. We can use our time on the moon to develop and test new approaches and technologies and systems that will allow us to function in other, more challenging environments. The moon is a logical step toward further progress and achievement.

A permanent moon base capable of harvesting and processing materials for constructing anything substantial will be very expensive; making it resistant to micrometeor impacts will also be very difficult, not to mention shielding against radiation present outside of Earth's magnetosphere.

Can't do any million-second exposures with an Earth based telescope - that's how long Hubble stayed pointed at one spot in the sky to create its Ultra-Deep Field image. Over several hundred orbits, it was able to point at the same spot. And it can acquire several groups of images a day - 90 minutes per orbit. On Earth, the spot will change place over the seasons - and you'd only get a chance at one imaging session a day. Cost suddenly goes up when it takes 16x longer to get deep-space images from the ground.


Interesting too is this on NASA's site:
Ultimately, a flight mission to Hubble will be required at the end of its time to either to return it to ground, raise it to a higher orbit, or guide it into a controlled re-entry (possibly with the aid of an attached booster).
Click to expand...
I guess that a re-entry booster could be done without human intervention. But there's an idea - send the shuttle to service Hubble, AND install the re-entry module on it at the same time. Extended life, and save the money of launching another rocket to get the thing down when its new warranty runs out.

Yep. Can't wait for that one. They're sending an 8meter reflector into space!!!
By comparison, hubble is only 2.4m, so the JWST is over a thousand times more powerful!
 
Why should they keep Hubble if they are going to put an even better telescope into orbit? Then you guys want NASA to service two telescopes? I am all happy and proud and whatever about what Hubble has done, but it has reached the end of it's lifespan. You all seem to complain about things, but for the most part NASA space equipment exceeds everybody's expectations.

For the most part.....this isn't just NASA, but 2/3 of all missions to Mars have failed. Some that do work do great things though. Hubble has great things in store too, if it could just be repaired and upgraded.


On key difference - the James Webb telescope can't see in the visible light spectrum. Hubble can.
And besides, Hubble still works; I think repairing it to get more out of it makes more sense than just scrapping a useful piece of equipment. You don't throw out a car with a damaged windshield, dead battery, old oil, and maybe a bad wheel bearing. You fix it because it works fine otherwise, and it's cheaper to fix than to buy a new one.

And just imagine if we applied that technology to a space mounted telescope!
