In 1964 I worked part time for The Space Astronomy Lab in Madison. WI. The Lab was part of University of Wisconsin research. At the time the Lab was doing early work on the Hubble Telescope. Among other things I made circuit boards for NASA tracking stations to upgrade the tracking stations for satellite and rocket tracking. I also was one of a few able to programmer the computer. One of the programs I wrote was to study the efficiency of movement of the telescope so it could take the best photo coverage possible with out wearing out the pivot points of the equipment. The reason was, that at that time the telescope was to be mounted on a gyro stabilized platform and the telescope would be moved into position for a photo by means of mechanical linkage. And because of the vacuum of space any lubrication would evaporate into space so the wear would be relatively rapid.
How much it changed by the time it was actually launched.
