Sun synchronous explanation
The common explanation for satellite 'precession' relies on planetary
spherical deviation - " The uniformity of sun angle is achieved by tuning natural precession of the orbit to one full circle per year. Because the Earth rotates, it is slightly oblate (the equator is slightly longer than it would be for a perfect sphere), and the extra material near the equator causes spacecraft that are in inclined orbits to precess " http://en.wikipedia.org/wiki/Sun_synchronous_orbit The actual cause does not rely on planetary spherical geometry but on orbital geometry and the specifics of orbital motion. The observed 'precession' is an orbital signature,something akin to an orbital version of Foucault's pendulum,where the planet orbitally turns beneath the satellite with each pass. This insight is gained through observations of Uranus by the HST,where planetary characteristics such as the equatorial rings and unique rotational orientation (tilt) along with orbital considerations,such as distance from Earth and the central Sun,allow for an isolation of the orbital specific. This observation is crucial for climate purposes as well as replacing the correlation between spherical deviation and satellite 'precession' with a more satisfactory explanation. |

Astrodynamicists already account for the apparent motion of the orbital plane due to Earth's rotation. The precession of the line of nodes is *on top of* that, and the effect is quite real. The new s.s.tech fails its first major test: not just getting punk'd by a net.k00k, but a net.k00k with a long history of spreading his k00kery on sci.space.* http://groups.google.com/groups/search?as_q=&as_epq=&as_oq=&as_eq=&num=100&scoring =&lr=&as_sitesearch=&as_qdr=&as_mind=1&as_minm=1&a s_miny=2009&as_maxd=1&as_maxm=1&as_maxy=2009&as_ug roup=sci.space.*&as_usubject=&as_uauthors=kelleher .gerald%40gmail.com&safe=off ======================================= MODERATOR'S COMMENT: Approved, but I will say we weren't punked. I allowed this thread so it could be debunked. I don't see much point in extending this thread further though. (I should have commented when I approved the original article btw.) Oh and Jorge, you should see some of the stuff that IS rejected. Makes this look rational and sane. :-) |

==================== MODERATOR'S COMMENT: Approved,
but I will say we weren't punked. I allowed this thread [...] Which of the three moderators wrote this? -- Kevin Willoughby lid It doesn't take many trips in Air Force One to spoil you. -- Ronald Reagan ======================================= MODERATOR'S COMMENT: My Bad. GDM. Sorry. |
