Slava G. Turyshev, Michael Martin Nieto, and John D. Anderson
have reduced the Pioneer deceleration anomaly
to a set of basic physics parameters:

I have updated (April, 2005) my paper:
http://arxiv.org/abs/physics/9905007
to incorporate the "Problem Set" parameters
and in its particular Pioneer spacecraft
translational and rotational parameters.
It is concluded (page 19-22)
that one space mass density (6.38E-30 g/cm^3)
based on elastic space lattice
and close to observed dark matter density
predicts the observed Pioneer spacecraft
translational and rotational deceleration
assuming this space mass density is available
to the spacecraft as momentum transfer (mc/area) (viscosity).
Note: that Pioneer spacecraft translational and rotational velocities
are three (3) orders of magnitude of each other
which makes the above observed
and calculated (no velocity dependence) deceleration
results rather remarkable.
<> The basic assumption is very simple:
Fx=mc^2
or F = Ma = (mc^2)/x
or in terms of conventional physics
<>1. F = M a = C * A * rho * c^2
(drag equation)
2. F = M a = 3 * pi * (mc/area) * c * D
(Stokes' equation)
where:
C= drag coefficient (near 1 for equation 1 and 24/(Reynolds' Number) for
equation 2)
A= spacecraft cross section area
rho = space density (6.38E-30 g/cm^3)
c = speed of light
M = mass of spacecraft
a = spacecraft deceleration
D= spacecraft diameter
<>mc/area= space viscosity 1.21E-16 g/(cm sec)
For a spacecraft with large area to mass such as Pioneer
then equation 1 governs.
<>For a planet such as earth, then equation 2 governs
but effect is negligible.
Spacecraft spin deceleration is computed with Problem Set
value for moment of inertia and standard torque formula
and assuming "pseudo paddles" on the Pioneer spacecraft
with some reasonable cross section.
<>It is like space is filled with "mines"
and when the spacecraft intersects them
their entire energy (mc^2) is imparted to spacecraft
with small but measurable effect.
This elastic space lattice probably does not exist
near earth orbit around sun because it is destroyed
by nanoTesla magnetic fields at the radius from the sun
but only "kicks in" at many astronomical units AU (>10) which is indeed
the experimentally observed case
On a galactic scale, such an elastic lattice could be assumed to exist
near the outer fringes and not the center (due to high magnetic fields)
and thus account for "dark matter" contribution
to galactic rotation.
Comments please.
