I just got around to reading the rest of this press release, and the
We all "know" how this particular experiment will turn out, but it's still
an interesting read.

The experiment will involve precisely measuring the angular
distances between several quasars, celestial objects in distant
galaxies that resemble stars. On Sept. 8, Jupiter will pass very
close to the primary quasar. When it does, its gravity will cause
the quasar's position in the sky
to shift by a distance that depends on the speed of gravity.
Kopeikin and Ed Fomalont, a radio astronomer with the National
Science Foundation's National Radio Astronomy Observatory (NRAO),
will use an observational technique they developed to compare the
position of the primary quasar to the position of other quasars
unaffected by Jupiter. Using their data, they hope to confirm the
accuracy
of Einstein's theory further.
