Possible Higher-Order Tests of Gravitation Theory in the Solar System

Significant progress has been made in showing that higher order tests of general relativity in the solar system can be done at the 10-5 or 10-6 level (relative to first post-Newtonian order) rather than at the 10-8 level as was previously believed. Several new ranging (laser or radar) experiments have been examined to this end.

• Nordtvedt's work was favorably reported upon in a front page article in the Wall Street Journal January 9, 1991
• Three papers were published in the Physical Review and the Astrophysical Journal
• Eleven invited talks given in France, Italy, and Switzerland
• Three year research grant was funded by NASA to continue this work
• Two year French Academy of Sciences fellowship received
