Einstein Was Right: NASA Announces Results of Epic Space-Time Experiment
It's not all that epic. These effects had already been measured by other experiments and were found to agree with general relativity to much more accuracy than the GP-B measurements. What GP-B brought to the table was a direct measurement, as opposed to indirect measurements used by the other experiments.However, because the way they measured it pushed the limits of engineering, if GP-B had NOT agreed with GR there is good chance the results would have been dismissed as most likely due to equipment flaws.While it is in general a good idea to confirm measurements, especially using different techniques, in a case like this where the confirmation will be much less precise than the other experiments and will likely be rejected if it fails to confirm, you have to wonder why this was funded over other projects.The answer to that turns out to be simple: politics. When space scientists ranked all the proposed missions under consideration, GP-B came in dead last. However, its proponents went to Congress, and got Congress to override the normal process for prioritizing missions, forcing NASA to move it to the front, ahead of more scientifically worthy missions.There are a lot of very worthwhile scientific missions that we can't fly due to budget limitations. It's a shame to see $750 million of the limited budget go to a mission so far down on the importance list.
