From a comment on the NYT mission “obituary”:
cordially,
Like others who have commented, I too was privileged to have worked on one of the components that crashed into Saturn today. This was the tri-partite diffraction grating that was a part of the VIMS-IR spectrometer, assembled by JPL. A machine called a 'ruling engine' was used to construct the grating. That machine was built by Albert Michelson and his colleagues and students at the University of Chicago in about 1910.Michelson (1852-1931) was the first American to receive the Nobel Prize for Physics. I rather think he’d have been tickled to know the use to which his contrivance was put.
cordially,
