VLA Dish Dipped in the Barn

A rare view of a dipped 25-meter dish antenna of the Very Large Array undergoing maintenance inside the Antenna Assembly Building, also called the Barn. The VLA has 28 of these giant antennas, but only needs 27 for the array. Having a spare means maintenance can happen year-round without a loss of astronomy time.
