    Here is a good article about the Pioneer anomaly, which cosmologists have been studying for a while. Apparently, it isn't going to fundamentally change our understanding of physics.

    Thirty years ago, NASA scientists noticed that two of their spacecraft, Pioneer 10 and Pioneer 11, were veering off course slightly, as if subject to a mysterious, unknown force. In 1998, the wider scientific community got wind of that veering—termed the Pioneer anomaly—and took aim at it with incessant, mind-blowingly detailed scrutiny that has since raised it to the physics equivalent of cult status. Now, though, after spawning close to 1000 academic papers, numerous international conferences, and many entire scientific careers, this beloved cosmic mystery may be on its way out.

    Slava Turyshev, a scientist at the Jet Propulsion Laboratory (JPL) in Pasadena, Calif., and Viktor Toth, a Canada-based software developer, plan to publish the results of their strikingly comprehensive new analysis of the Pioneer anomaly in the next few months. Their work is likely to bring a conclusion to one of the longest and most tumultuous detective stories of modern astrophysics.

    I've read a bit about this.

    This may lead to some rework of Newtonian mechanics and therefore relativity theory. This is new science happening right now -very exiting.

    Interesting article and not surprising. "Physics as we know it worked well." -- Slava Turyshev


    Here is the preprint that has been published, with, I think more to come.
