A few weeks ago Physical Review published a Letter (an edited version of http://arxiv.org/abs/gr-qc/0702028" [Broken]) that says: "At this time, [Lunar Laser Rangefinding] provides the most precise test of [the gravitomagnetic phenomenon,..] likely better than the ultimate result from the GP-B experiment." Furthermore, "new effort in LLR is poised to deliver order-of-magnitude improvements in range precision [..and] requires only about a year of new data collection[.., which means that] a significantly improved test of this phenomenon is not far away." The letter concludes it would have to be "a profound empirical clash" if GP-B doesn't also match the predictions of GR. So, is GP-B already obsolete? Does that make GP-B irrelevent, or is its "directness" still important? Or is the letter just wrong (say, will gr-qc/0702120 pass peer-review)?
