ANOMALOUS GRAVITATIONAL FORCE?  A discussion of this phenomenon appears
in the 4 October 1999  issue of Newsweek magazine (See also the
December 1998 issue of Scientific American.) The mystery of the tiny
unexplained acceleration towards the sun in the motion of the Pioneer 10,
Pioneer 11 and Ulysses spacecraft remains unexplained.   A team of
planetary scientists and physicists led by John Anderson (Pioneer 10
Principal Investigator for Celestial Mechanics) has identified a tiny
unexplained acceleration towards the sun in the motion of the Pioneer 10,
Pioneer 11, and Ulysses spacecraft.  The anomalous acceleration - about
10 billion times smaller than the acceleration we feel from Earth´s
gravitational pull - was identified after detailed analyses of radio
data from the spacecraft.

Viszlat!
