From Friday Harbor to the Edge of the Solar System

Just got this note from David Grove over at Luxel Corporation – it seems there are some Friday Harbor products passing Pluto right now…
I thought you might like to know that one of the instruments on the New Horizons satellite (now arriving at Pluto) uses filters made on San Juan Island.
The PEPSSI (Pluto Energetic Particle Spectrometer Science Investigation) will be used to measure the extent of Pluto’s atmosphere and it’s interaction with the solar wind.
Two filters made by Luxel Corp. are used in the PEPSSI spectrometer to tell what’s escaping from Pluto’s atmosphere. At less than 1/100 the thickness of a human hair, they were a bit tricky to make.
These are engineering (prototype/ test) filters for PEPSSI. Not the actual filters on the satellite but working copies – Photo courtesy of Luxel Corp.
