HockeyPuck writes: Before a color guard and the wife of a hero, they said goodbye Wednesday to a famous artifact of space and the Cold War — Onizuka station (aka Sunnyvale's "Blue Cube,") — named for pioneering Asian-American astronaut Ellison Onizuka, who was killed in the 1986 Challenger crash. The windowless blue box that housed secret operations for four decades. In its first 25 years, the people at the center did critical work as a global antenna for military and civil satellites. In many ways, it is a monument to technology long since supplanted. The Cube was built to house big mainframe computers, which demanded temperatures in the 60s. Even now, the rules of classification forbid the Cube's veterans from talking about most of what they did, but they can tell a few fond stories of how they did it.
