A photo of the Parker Solar Probe was captioned as follows:
In the Astrotech processing facility in Titusville, Florida, near NASA's Kennedy Space Center, on Tuesday, June 5, 2018, technicians and engineers perform light bar testing on NASA's Parker Solar Probe.
I wasn't able to find any references to this sort of process in NASA literature - even Armadillo's Ben Brockert was perplexed.
Is this something specific to the Parker probe, or a standard NDT process?
