Hubble Verdict: De-Orbit 308

theonetruekeebler writes "CNN reports that NASA has reached a final decision for the Hubble space telescope: De-orbit. At some future date a liquid-fueled rocket will dock with the telescope and fire, hurling Hubble into the ocean. However, "Our best estimate is we probably will be able to continue to do science as we're doing it ... somewhere into 2008," according to program executive Mark Borkowski."

      There is a reason NASA wants to trash Hubble. With Hubble gone, it'll be easier to justify the next scope. Right now, it's easy to say, "What's wrong with what we've got?" Yes, compare|contrast images have been shown - comparing "regular" tv to HDTV - and there is a difference. But when you see the pricetag, it's still easy to say, we have one right now turning out pretty nice pictures. Get rid of the status quo, then say, "oooooh. look at the pretty pictures." and people will go along with it - new posters for office walls, Timmy's bedroom ceiling (to stair at whilst he's falling asleep - until he gets to be ten or eleven, then something else will be up there).
      It's just like a kid wanting a new computer, bike, skateboard, baseball glove, or anything else. "Well, son. Doesn't the one you have right now work?" "Well, yeah, but...."

      NASA's just trying to eliminate the the status quo works and is cheaper argument.

        Actually this is a very common misconception.

        Any satellite in a stable orbit is in freefall and expending none of its own energy to stay in that state. To change orbits, either up OR down requires a change in velocity, and that change in velocity requires fuel. So up is just as difficult as down energy wise.

        The only free ride you get in the down direction is when you get low enough so that atmospheric drag begins to slow you down.

            Everything you said is correct except Hubble has no engines to fire - it has no thrusters. It depends on boosts from the Shuttle to keep it from deorbiting just like the space station does.

            Hubble is so high up that it would take years for atmospheric drag to cause a de-orbit. To cause a controlled de-orbit means flying up and attaching a thruster. Since they had (still have) to do this anyway, trying to repair it wasn't that much more expensive.

      Hubble is meant to run mainly off solar power. Shooting it out of the solar system would make it useless after it got a short distance from the sun. Its communication system is not made to broadcast very far, and giving it a high velocity would drastically decrease its ability to take clear pictures. Also, it isn't really made for "extra-terrestrial contact". It doesn't have any greeting plaque, just some dirty pictures written on it by astronauts and the various labels and warnings on the parts.

      Blowing up old satellites is a very bad idea. Orbital debris is already dangerous for rockets and (especially) manned missions into space. Collision with a piece of debris in orbit is usually a very high-speed impact and can severely damage or even destroy a launch vehicle. For the future safety of space exploration, it really is safest to send satellites into the atmosphere to burn up cleanly.

      Shooting a derelict satellite into deep space is much more costly (in terms of fuel) and is not as easy as it sounds. If it isn't done right, it might end up in an eccentric orbit around the Earth (or moon) and cause problems much later on.
    • Try a google for Kepler Syndrome. You'll find sites that explain it better than I can, but basically, debris hits something, and it creates more debris. These go on to create more collisions and more debris, eventually closing off an entire orbit plane.

    I don't see why they need to do anything to the Hubble at all. They don't have money to keep it operational, but there is funding to hire engineers, procure raw materials, build a rocket, launch it, dock the damn thing, and ram it into the atmosphere? Why not just do nothing and leave it up there? Kind of like what the navy does with old ships - keep it in the mothball fleet but don't necesarily strick it from the registry. Who knows what uses it may have in the futher? I suppose one would argue it is a possible collision risk to other operational satelites which might have intersecting orbits, but what's one more object to the thousands already being tracked by military radars?
    • The reason they have to do something with it is that if they do nothing, it will stop being able to make the little corrections that keep it in orbit. If it falls out of orbit uncontrolled, it could land on people or property. Better to shoot it down so that we can control where it goes.
    • Believe it or not, there is some friction up there in orbit, even though we describe it as "hard vacuum." There's not much, granted, but there's enough drag that it will eventually pull the Hubble (and anything else in orbit) down into the thicker atmosphere. Most all satellites have some thrusters/rockets built in to them to allow them to self-correct their orbits...but, those require fuel...once the satellite's out of fuel, it's coming down...the only question is where.
      • Well, this is wonderful! I recall one of the reasons for *not* servicing Hubble was that it was too risky for the shuttle to go higher than it normally flys, especially after Columbia. What is wrong with letting friction do it's work and bring Hubble down to a safer altitude where it is safer to work on? Instead of building a rocket to crash Hubble into the ocean, it can be used to boost the repaired Hubble back into it's old service orbit.

      It's falling out of orbit (slowly) and there's a 1 in 700 chance it'll hit people when it lands. They want to bring it down into an ocean under control.

      It only has enough battery and gyroscope life left to be useful for another couple years without service so at that point it's just a danger and they've deemed it too risky to fix.

    Whatever they send up there HAS to have a strong dock to tow it back safely, so why not let it wait for a while once it gets there.

    Once it docks, it can take over control of hubbles positioning requirements leaving it to carry on working for a much longer period.

    Then, when the fuel is gone and the items once again begin to fail, fire the main return home booster to de-orbit?
    • Much as I admire the effort behind the Hubble project, Hubble is dead. It is gone. And for the cost of keeping it going another 4 years, you could design, build and launch another, lighter, more modern telescope.

      It's like trying to run Doom 3 on the latest Alienware retrofitted with a 486, no matter how much you bolt on it still will fail. Sometimes you just need to dump the older bits and upgrade the whole kit. Hell, send up a fleet of new ones and put them at Lagrange points.

    It's already like a junkyard up there. Even though I will mourn the passing of Hubble, NASA is quite correct. Blowing it up is dangerous. We can't afford to have uncontrolled, unmonitored crap floating around up there. It takes much less energy to bring it down than accelerate it to the point it breaks free from Earth, so it's cost-effective and environmentally sound to do exactly what they're proposing.

    Of course, I'm sure we'd all prefer they didn't scrap it at all. What it has taught us has vastly improved our knowledge of the space around us and, IMO, we will be that much poorer without it.

    Anyone working for NASA automagically has more balls than I, but damn. It's been nothing but bad news these last few days, what the hell?

    Why not turn hubble into a big vacuum cleaner! As it de-orbits it scoops up all the debris in orbit forming a massive mountain in front of it. The more orbits the bigger it gets, the more debris it attracts. And when mom approves, THEN we dump the whole thing into the Pacific Ocean, and sell it to Disney for a new theme park!!
  • Why not sell it instead?!

    They can privatize it. They can give it to the public somehow.

    But why spend the money to bring it down??? I don't get it.

    The main advantage of space for a telescope was avoiding atmospheric distortion. Now it is possible to adjust the mirrors to compensate for atmospheric distortion (adapive optics [ucolick.org]), enabling large and clear telescopes on the ground (Earth). Here's an explanation of how a guide star is used to "eliminate twinkling" [wikipedia.org]. In short, orbital telescopes may be obsolete once these technologies are perfected.

    There was money included in NASA's budget for FY 2004 or 5 that was specifcally for fixing Hubble.

    Has nasa become such a group of pussies they are too chickenshit to even try now. We lost men going to the moon but we went anyway no different in putting up the space stations or fixing the hubble.

    Hubble has one advantage that all of our other fixed telescopes and that is a great deal more mobility.

    They could at least put a booster rocket on it and put it into a storage orbit until we can fix it.
