Long before he flew four missions on the space shuttle, Steve Robinson was the first DJ of a now-vanished Davis commercial radio station, KYLO, in the late 1970s. Decades later, he’s a professor of mechanical and aerospace engineering at UC Davis, and director of its Center for Space Flight Research — and he will soon return to local radio as occasional fill-in host for Rod Moseanko, host of the station’s Silver Nine Volt Heart. (The photo shows Steve, left, and Rod in the KDRT studio May 11.)

Today on Davisville we enjoy a serious conversation about space flight, plus hear Steve’s memories of KYLO — including what happened when he told listeners he was running out of records to play  — and learn what brought him to KDRT. After he returned Davis in 2012, Robinson said, “I was looking for some good radio,” and found it with Rod’s show. “I thought, ‘this kind of radio is still alive. It was very exciting to me.’ ”
