   Gravity Probe B

   Gravity Probe B (GP-B) is a satellite-based mission which launched in 2004. The spaceflight phase lasted until 2005, and data analysis is currently under way (as of May 2008) and may continue to into 2010.

   General relativity

   More recently, it has been measured for test masses aboard the satellite Gravity Probe B to a precision of better than 1 percent.

   Frame-dragging

   The Gravity Probe B experiment is currently under way to experimentally measure another gravitomagnetic effect, i.e. the Schiff precession of a gyroscope, to an expected 1% accuracy or better.
8. close

   Gravitomagnetism

   It is an approximation to the current standard theory of gravitation, and has testable predictions, which are in the final stages of being directly tested by the Gravity Probe B experiment.
9. close

   Geodetic effect

   The geodetic effect was verified to a precision of better than 1 percent by Gravity Probe B, an experiment which measures the tilting of the spin axis of gyroscopes in orbit about the Earth.

    Orders of magnitude (magnetic field)

    5 aT -SQUID magnetometers on Gravity Probe B gyros measure fields at this level over several days of averaged measurements
