Typical CNN propaganda :) which tries to hide all the details and
avoids giving any publicly available URLs because, shock horror, readers
might actually *read* the URLs and think for themselves. Wouldn't that
be dangerous...

(Correction: they give links to space.com sites, but nothing to anything
like a usenet discussion group, a wiki, a publicly available journal
article, or a GFDL version of the article... But don't worry, dinosaurs
will become extinct naturally :)

: The results, announced today, are much more precise than preliminary
: findings published by the same group in the late 1990s.

: The researchers say their result is 99 percent of the predicted drag,
: with an error of up to 10 percent. The details are reported in the Oct.
: 21 issue of the journal Nature.

It's news nearly a decade old: Ciufolini announced a detection of the
Lense-Thirring effect precise to 25% eight years ago but Nature (it seems)
refused to publish it:

http://arxiv.org/abs/gr-qc/9704065

Of course, there's a wikipedia GFDL article on it:

http://en.wikipedia.org/wiki/Frame-dragging

A Nature discussion article is also available to ordinary readers:

http://www.nature.com/news/2004/041018/full/041018-11.html

which says that the Gravity Probe B group are sceptical about the
result: measuring an expected property of GR is an experiment where
you know what result to expect in advance...
