Lowering a Receiver
When a large receiver is removed from the Green Bank Telescope’s prime focus, it takes an unusual route back to the electronics lab: via wires. In this photo, the new Ka-band Focal Plane Array is too big to ride the elevators down the GBT, so instead, it is lowered carefully to engineers on the ground who have a truck waiting to bring it back to the lab.
