The need to avoid lubricant out-gassing was critical in this application because the vacuum of space can extract - "out-gas" - some of the lighter constituents of the lubricant. The out-gassed materials might then be deposited on the mirrors, reducing their reflectivity and affecting the system's operation. The high cost of power in space dictates the use of relatively low powered lasers, so high reflectivity mirrors are very important. Even a small reduction in reflectivity can be crippling.Any reduction in reflectivity might also cause the mirror to absorb more laser energy than it was designed for, possibly enough power to damage the mirrorThe galvos also had to maintain accuracy in the vacuum of space, which causes conventional lubricants to quickly evaporate. By reducing lubricant efficiency, out-gassing could cause the galvanometer bearings to fail, clearly unacceptable given the nature of the mission.
