Paper on Dynamics of an Earth Ring
Here is a short paper in which I make an argument that any ring system
around the Earth could not remain dynamically stable for long in the complex Earth-Moon-Sun interactive environment:- http://uk.geocities.com/aa_spaceagen...-dynamics.html However.... some experts appear to suggest that such an "Earth ring" could perhaps have existed for thousands of years, causing climatic effects on the Earth, as revealed he http://www.sandia.gov/news-center/ne...ringworld.html I wonder if anyone here has any views on this, or if there's some other factor that I ought to have taken into account in my analysis?

*follow-ups trimmed - this has nothing to do with shuttle or station.
sci.space.policy has an (un?)official 'catch-all' role* "AA Institute" wrote ... http://www.sandia.gov/news-center/ne...ringworld.html I wonder if anyone here has any views on this, or if there's some other factor that I ought to have taken into account in my analysis? (uninformed speculation follows) Well maybe they count debris within +/- 15 degress of the equator as 'a ring'. Alternatively their article does rather gloss over the ring stability in favour of the climatic impact - maybe their expertise just isn't as hot in that area. |

*follow-ups trimmed I didn't realise these groups were moderated?! - this has nothing to do with shuttle or station. Not immediately, you're right. However, if the station were to be disassembled or expanded in the future by boosting it to a higher orbit, then the dynamic instability of containment of any resulting orbital debris in a perfect ring formation could become highly relevant for all orbital spaceflight.

(uninformed speculation follows) Well maybe they count debris within +/- 15 degress of the equator as 'a ring'. The scatter of debris over a 30-degree range would make the formation so sparsely spread out as to make a significant blot out of sunlight to impact Earth climate, impossible - IMHO. |
