John Batchelor and I welcomed back Stephanie Thomas of Princeton Satellite Systems to update us on progress with both fusion energy and fusion propulsion for space.  Stephanie talked about PSS and their work on a direct drive fusion rocket engine for propulsion, she mentioned timelines plus she mentioned other fusion methodology. We also talked about research for fusion for space and fusion for electricity here on Earth.  Stephanie brought up shorter travel times to the planets with fusion, demo propulsion flights which still need two advancements before becoming reality. She went over each of the advancements needed with possible timelines. Also discussed was the fusion fuel of choice, mass considerations for propellant for space fusion power plus suggested timelines for that segment.  In addition, she was asked about fusion funding and if it was sufficient for their company and the other commercial fusion companies along with the government Tokamak reactor R&D.  Visit their website at www.psattelite.com.
