The pointing control system of the Earth orbiting Hubble Space Telescope. Engineers on Earth shut down one of the three operational gyroscopes aboard Hubble. A two-gyro science mode should preserve the operating life of the third gyro and extend Hubble’s science observations through mid-2008. Credit: NASA, ESA, A. Field and K.
