Maintenance on High
A telescope engineer rides the traveling feed of the 300-foot telescope that used to be in Green Bank, West Virginia. The 300-foot telescope could not move across the sky, only dip itself up and down. This feed supported receivers on tracks that drove it from side to side above the dish, following the apparent motion of astronomical objects overhead caused by the turning of the Earth.
