Not sure where to put this, so I'll drop it here. It seems that both NASA and ESA are committed to performing tests that may show deviations from GR. NASA has LATOR http://science.nasa.gov/headlines/y2004/26mar_einstein.htm [Broken] And ESA has LISA http://www.esa.int/esaSC/120376_index_0_m.html and GAIA, http://www.esa.int/esaSC/120377_index_0_m.html and BepiColombo http://www.esa.int/esaSC/120391_index_0_m.html The main ESA fundemental physics page explains the relation between the missions: http://sci.esa.int/science-e/www/object/index.cfm?fobjectid=30467 All of these mission should be operational by the end of the decade. All in all, I think that the 2010's will be an exicting time to do physics, as we may finally get some new experimental results that the theorists (which I will hopefully be joining) can sink their teeth in. Any thoughts, comments?
