The next video from the September 2019 SSI 50 Space Settlement Enterprise gathering held at the Museum of Flight in Seattle is SSI Senior Associate Professor Heidi Fearn’s Monday Lunchtime presentation “Mach Effects For In-Space Propulsion.”
This short but excellent video shows the current updates of Professor Fearn’s and Professor James Woodward’s (and Chip Akins’, John Brandenburg’s, T. Marshall Eubanks’, SSI President Gary C Hudson’s, Daniel Kennefick’s, Paul March’s, José Rodal’s and Jonathon Woodland’s) work on the NASA Innovative Advanced Concepts MEGA Drive work.
As always, Professor Fearn kept even the non-physicists in the crowd fascinated and we hope that you enjoy the video as much as we all did live in Seattle.
Oh, by the way!  Heidi quickly mentions something that some folks weren’t aware of.  The August 2019 issue of Scientific American featured her and Dr. Woodward and the project work in the 8 page article by Sarah Scoles entitled “The Good Kind of Crazy.”

See up at the top right, “Fringe Physics – Wild ways to propel our species to the stars”?

If you missed it and don’t have a subscription to Scientific American so you can read it online, you can buy reprints from this link.  (Personally I just went to eBay and bought a couple of more physical copies to give to friends, paid about 9 dollars each.)
In any case, even newer information is now on the SSI YouTube Channel, from Professor Fearn’s Monday September 9th SSI 50 Lunch presentation.
Enjoy!
