Application: a Meteorological Satellite.
Since the 1960's, designers of scientific satellites have been combing technical libraries throughout the world for new,
more efficient means to achieve very accurate displacement of optical slides and lenses in space vacuum with little or no
lubricant and extremely high reliability and repeatability.
Everything available was tested on Earth before they decided on which one to use and launch into space.
Satellite Roller Screws became the muscle of choice for space applications.
