Decades in the making, GP - B was launched in April 2004 to sensitively measure two properties of spacetime: the geodetic effect, a 2.8 - centimeter (1.1 - inch) contraction in the circumference of Earth under its own gravity; and frame dragging — the weaker of the two and GP - B's main quarry — in which Earth twists spacetime like a ball rotating in honey.
The speed and pace of those measurements promise to add an increment of precision to GPS navigation, and ROMY may even be able to detect a subtle effect predicted by Albert Einstein's theory of general relativity: the drag of the rotating planet on nearby spacetime, like a spoon turned in a pot of honey.
What's more, the Earth's rotation should also produce a drag on local spacetime, like a marble spinning in molasses would pull the goop around it.
