The team was led by Dr. Ignazio Ciufolini of the National Research Council of Italy and the Aerospace Department of the University of Rome, and Dr. Erricos Pavlis of the Joint Center for Earth System Technology, a research collaboration between NASA's Goddard Space Flight Center, Greenbelt, MD, and the University of Maryland at Baltimore County.
Frame dragging is like what happens if a bowling ball spins in a thick fluid such as molasses.
As the ball spins, it pulls the molasses around itself. Anything stuck in the molasses will also move around the ball. Similarly, as the Earth rotates, it pulls space-time in its vicinity around itself. This will shift the orbits of satellites near the Earth. This is about 10 percent greater than what is predicted by general relativity, which is within our margin of error of plus or minus 20 percent.
