great job posting a 2 week old article :roll:...<br /><br />New NASA chief, new decisions, time will tell what happens to Hubble.

That Michael Griffin. Something about the winning smile told me this man would be different. <img src="/images/icons/laugh.gif" /><br /><br />Great news, and reason to be cautiously optimistic.

Thanks for the info and the good news, shuttle_guy, I'm delighted. Is it true that Gregory Benford is planning to boost power of the solar sails designed by friedman by using Laser?? <div class="Discussion_UserSignature"> <font size="0" color="#10bdee"><strong>A dazzling bluish luminosity from A distant south pacific.</strong></font><p><br /><img id="cb51e87e-8221-424c-8ff2-78c95122196c" src="http://sitelife.livescience.com/ver1.0/Content/images/store/11/15/cb51e87e-8221-424c-8ff2-78c95122196c.Large.jpg" alt="blog post photo" /></p> </div>

I have some questions:<br /><br />a- can the Hubble (after we service it) be used for the pinhole project ?<br /><br />b- can a small navigation craft like the size of the shuttle bay be built to move<br /> the ISS and/or Hubble out up to a million miles and back? like a mini-shuttle, this <br /> one stays parked at the ISS, though(But eventually a small space port could<br /> be built. <br />To keep this simple, It only basically elevates the ISS/or Hubble<br /> and brings it slowly back down every time there's a rocket or shuttle rendevouz<br /> appointment. Wouldn't this be simple (relatively speaking, I mean it sure seems more<br /> simple than waiting for a not yet proven moon base or one on Mars) It seems like I'm<br /> talking about something like the human-spacewalking personal navigation backpack<br /> only sophisticated enough to handle the ISS, Hubble, and anything else we would like <br /> to move up or down. <div class="Discussion_UserSignature"> </div>

On question B, the answer is yes, such a craft can definitely be built and attached to either ISS or the Hubble. It's basically a propulsion module, and those things have been built for years. Although it'll need to be designed and built and paid for, the technology is basically there.<br /><br />The problem is the propellant. You'll need to feed this propulsion module, and ISS is very big, which means it takes a lot of prop to move it. That's the part that ultimately makes this impractical, at least with the thrust levels and specific impulse currently available. (Ion drives are currently too small to really be useful for this; they haven't got the thrust.)<br /><br />The most practical idea I've seen for this came from Martin Lo. I started a thread about it with "Lagrange" in the title. It's one of those schemes where "it's so crazy, it just might work," except that he's got the mathematical genius to prove it. (Plus, the basic concept was proven by Genesis, believe it or not.) It only works for very specific locations, however. You can exploit Lagrange (or libration) points to move even very massive objects around, as long as you're really patient.<br /><br />It's not really useful in low Earth orbit, however. Lo's scheme (called the Interplanetary Highway) really only works if you're near a Lagrange point, like Earth-Moon L1, which is much closer to the Moon than it is to Earth. <div class="Discussion_UserSignature"> <p> </p><p><font color="#666699"><em>"People assume that time is a strict progression of cause to effect, but actually from a non-linear, non-subjective viewpoint it's more like a big ball of wibbly wobbly . . . timey wimey . . . stuff."</em>  -- The Tenth Doctor, "Blink"</font></p> </div>

Do you think there will be a succesor to the hubble Space telescope, as in a much larger,more power ful one? ie; Hubble 2? how cool will that be! <img src="/images/icons/smile.gif" />

Callie, he ment bringing the hubble to the ISS, not the ISS to hubble.

actually my idea started with building a very large telsecope at the ISS, where humans<br />already work outdoors. If the ISS is way too low , I think a propulsion module ought<br />to built to move the ISS higher to build it there, or to move whatever constructs we can put<br />put together at the ISS higher, either one.<br />but Jurgen you have yet another good idea, I mean what if a small propulsion module<br />brings Hubble down, then up even higher?<br /><br />basically I think we need a mini-space shuttle, a mini spaceship. One that doesn't come to earth, to keep it simple, only for moving assemblies from somewhere in space to somewhere<br />else in space.<br /><br />while we're on the subject, couldn't a 'Giant' solar sail be built to move these things? (the Hubble, or whatever we assemble up there?)for example to lagrangre points and back and forth ? <div class="Discussion_UserSignature"> </div>
