Believable Pioneer anomaly updated

Very interesting!:
' one is left with an anomalous acceleration of the same amount with great
accuracy during a very long time interval for both Pioneer 10/11 to
explain.'
' the conventional explanation we suggest for the Pioneer 10/11 anomalous
acceleration versus spin-rate change points out in favour of the possibility
that something new of physical interest may be responsible of the main
Pioneer anomality '

Yeah, stooopid - lunar laser ranging and the Nordtvedt effect.

Yeah, stooopid - http://arxiv.org/abs/gr-qc/0308010
Nature 425 374 (2003)

The link says the Cassini Radio Science Team withdrew the paper. Any ideas
why they might have done that? Just curious here...

Beats me. It looked like a very sweet experiment. Email Giampieri
and find out.

The only explanation that I can think of is that the same data and
conclusion is in Bertotti's paper ("A test of general relativity using
radio links with the Cassini spacecraft" B Bertotti, L Iess and P
Tortora, Nature vol 425. No. 6956 p. 374, doi:10.1038/nature01997) but
I'd be interested to hear anything more.

Yeah, stooopid - lunar laser ranging
Yeah, stooopid - the old lightspeed measurements using observed
orbital time lags of Jupiter's Galilean moons.

Yeah, stooopid - communicating with the Martian rovers, the
Galileo
Jupiter orbiter, Cassini going to Saturn...

Yeah, stooopid - radar bounced off Saturn's moon Titan

We have gone over each of these before, my friend, and shown
them to have assumed light speed but not really tested it.
The Galileo moon lags are equally attributable as Cassini said
to the changes in viewing angle from the Earth given the planes
of the two orbits.

It is stupid to snip the discussion and answer to your
objection and simply state the objection again.
If you think that my answer that the lunar laser reception was
scattered and that faint receptions after 2 and 21/2 seconds
could be ascribed to this scattering and the real return was
after 2 seconds then say so.

These are perfect examples of assuming the speed of light and
not testing it.

And the results are vague and chosen so as not to be
inconsistent with other data on Titan.
