No evidence yet for torsion or conformal local gauge group gravity currents from this NASA probe.
Local gauging of symmetry groups of quantum fields induce source currents. The spacetime symmetries are universal - this is a deep way of understanding the strong equivalence principle with minimal coupling (SEP). Einstein's 1916 General Relativity is a simple gauge theory of the 4-parameter translation group generated by the total energy-momentum of the classical and quantum fields in the unambiguous flat case prior to local gauging. Local gauging is the direct result of classical signal locality, i.e. no controllable signals faster than the speed of light in classical vacuum (zero dark energy density). This can be generalized to the de Sitter (dS) group.

1.  GRAVITY PROBE B: EXPERIMENT CONFIRMS THAT SCIENCE IS OPEN.
It took 52 years and $750 Million, but the Stanford-based analysis group
and NASA announced on Wednesday that the data from GP-B does indeed confirm
two key predictions of Albert Einstein's 1916 general theory of
relativity:  the geodetic effect of space-time warping around a massive
object, which we perceive as gravity, and the frame-dragging effect caused
by mass-energy currents, called gravitomagnetism in beautiful analogy with
Maxwellian electromagnetism.   The findings were published online in
Physical Review Letters.  Of what value is it?  Above all it confirms that
science is open.  The success and credibility of science are anchored in
the willingness of scientists to expose ideas and results to independent
testing and replication. Had they gotten a different result, textbooks
covering the subject would be rewritten.  More than 100 PhD candidates
worked on some aspect of the gravity probe B experiment.  They are of the
measure of its value to society.
