In 1916 Robert Andrews Millikan measured both the frequency of the light and the kinetic energy of the electron emitted by the photoelectric effect and obtained a value for Planck's constant h in close agreement with the value that had been arrived at by fitting Planck's radiation law to the blackbody spectrum obtained by Wien.
A kilogram will then be any mass which elicits a reading for Planck's constant on a watt balance that coincides with the now-fixed value.All this sounds much more complicated than weighing from time to time a piece of metal stowed away in a vault.

The detectors for the telescope used to make the observations were made by the same group—led by Jamie Bock at the California Institute of Technology that developed detectors for Planck.
From there, they were manoeuvred to their operational orbits around the libration point L2 of the Sun Earth system: a halo type orbit for Herschel and a small amplitude Lissajous orbit for Planck.
