The center of gravity is now offset, though, which would lead to an imbalanced spin. A special adapter plate was manufactured for the spindle to be directly under this configurations’ center of gravity. https://images.squarespace-cdn.com/content/v1/5b3bd5a9266c077a5bdfcafd/1534356101044-CMSUYK6HF2RO13SYBHIU/Spin+Test+Pic+2.jpg Spin Test The spin platform is pictured in detail here. The tube in the foreground provides compressed air which allows the spindle to spin at a low friction. On the opposite side is a photodiode encoder hooked up to an oscilloscope. That provided the reference spin period that we could use to compare with spacecraft data. https://images.squarespace-cdn.com/content/v1/5b3bd5a9266c077a5bdfcafd/1534356152927-50TDCI4EJN08TFTVD6O0/Spin+Test+Pic+4.jpg Spin Test Here, Carter (’17) is about to turn ELFIN on.
