Welcome to the NRAO in Green Bank, West Virginia

NRAO operates the Robert C. Byrd Green Bank Telescope (GBT), the world's largest fully steerable single aperture antenna. In addition to the GBT, several other telescopes exist at the Green Bank site.

The Green Bank Telescope will track and monitor the Phoenix Lander as it descends through the Martian atmosphere on May 25, 2008. The Phoenix Lander will touch down in the northern arctic plain and will use a robotic arm to dig below the surface in search of subsurface water ice. At left is an artist's concept depicting the Lander just before touchdown on the Martian surface. For more information visit the Phoenix website at http://phoenix.lpl.arizona.edu/
