Today's Launch
After more than 40 years of work, the Marshall-managed Gravity Probe B is scheduled for launch today at 12:01 p.m. CDT. Coverage on NASA TV has already begun, and will continue until the seperation of the probe from the launch vehicle at 1:30 p.m. CDT. " NASA's Gravity Probe B mission, also known as GP-B, will use four ultra-precise gyroscopes, orbiting the Earth in a unique satellite, to experimentally test two extraordinary predictions of Einstein's 1916 theory that space and time are distorted by the presence of massive objects. The two effects being tested are: The geodetic effect, the amount by which the Earth warps local spacetime in which it resides, and the frame-dragging effect, the amount by which the Earth drags local spacetime around with it as it rotates."
