A couple weeks ago I had a short time in MIT's Space Propulsion Lab photographing some of the team behind the ion Electrospray Propulsion System (iEPS) for CubeSats. I'd photographed the group previously before for MIT News, but this time the focus was on two graduate students who are working to commercialize the technology with a new company called Accion Systems Incorporated. This time I got to peek inside a cleanroom where some of the components are manufactured from silicon wafers. It was a difficult shooting environment; only a couple of pieces of equipment could be brought in, and I was wearing a full "bunny suit" which doesn't have much in the way of ventilation.
