A test version of ESA’s Proba-V Companion CubeSat seen during preparation for ‘thermal balance’ testing in the Agency’s Mechanical Systems Laboratory at its ESTEC technical centre in the Netherlands.
Space is a place where it is possible to be hot and cold at the same time, if one part of your satellite is in sunlight and another face in shade. A satellite’s interior needs to maintain a steady temperature to go on operating properly.
Accordingly this ‘structural and thermal model’ of the Proba-V Companion CubeSat was placed inside the Large Vacuum Facility of ESA’s Mechanical Systems Laboratory – employed to test large satellite systems or complete small satellites – for a week-long exposure to temperature extremes in space-quality vacuum. ....

Stanford activists 'Disturbed the War' in the 1960s and 1970s

I entered Stanford University in the fall of 1966, majoring in Physics and looking forward to a career in the emerging computer industry. I had read how the Stanford Provost, Frederick Emmons Terman, Jr., had pioneered the concept of a “Community of Technical Scholars,” combining campus brainpower with local industry to create what later became known as Silicon Valley. 
Unfortunately, the narrative failed to mention a third partner, the U.S. Department of Defense. Stanford’s Engineering School and the university’s wholly owned subsidiary, the Stanford Research Institute (SRI), were essential elements of the military industrial complex. At that time, it meant that Stanford research had gone to war in Southeast Asia. ....
