Standing on the Great Big Thing

Years ago, staff were permitted to walk out on to the 2.3 acre surface of the Green Bank Telescope. Now, with new scientific needs requiring the GBT’s surface to be hyperaccurate, no one is allowed on the 2004 aluminum surface panels unless they are doing critical maintenance, including painting. In this photo, the shadow of the 64-foot feed arm dwarfs the folks on the dish.
