Plasma Thruster Could Dramatically Cut Down Flight Times to the Outer Solar System

Proposed Theoretical Propulsion Plasma Rocket c. NASA Public Doman

I just finished the most recent season of The Expanse – my current favourite Sci-Fi series. Unlike most of my other go-to Sci-Fi, The Expanse’s narrative is (thus far) mainly contained to our own Solar System. In Star Trek, ships fly about the galaxy at Faster-Than-Light speeds giving mention to the many light years (or parsecs *cough* Star Wars) travelled to say nothing of sublight journeys within solar systems themselves. The distances between stars is huge. But, for current-day Earthling technology, our Solar System itself is still overwhelmingly enormous. It takes years to get anywhere.

In The Expanse, ships use a fictional sublight propulsion called The Epstein Drive to travel quickly through the Solar System at significant fractions of light speed. We’re not nearly there yet, but we are getting closer with the announcement of a new theoretical sublight propulsion. It won’t be an Epstein drive, but it may come to be known as the Ebrahimi Drive – an engine inspired by fusion reactors and the incredible power of solar Coronal Mass Ejections.

Clearly a Fan. Jeff Bezos Himself Announced that Amazon was Picking up The Expanse

At Comic-Con 2015, fans of space opera and science fiction were treated to their first glimpse of The Expanse, the miniseries adaptation of Daniel Abraham and Ty Franck’s novels. Needless to say, the reaction was magnificent, and is perhaps best up by IO9’s Lauren Davis, who penned a review of the trailer titled, “The Expanse Is the Show We’ve Been Wanting Since Battlestar Galactica.

It was therefore a bit of a blow when recently, the Syfy network announced that the third season (which is currently airing) would be the show’s last. Reaction to the news was swift, prompting fans to mount multiple campaigns to have the show picked up by Netflix, Amazon Prime, or another video streaming service. And on Friday, May 25th, Jeff Bezos (founder of Amazon and Blue Origin) obliged them.

The announcement was made at the National Space Society’s International Space Development Conference in Los Angeles Friday night. Bezos was attending the conference to receive the prestigious Gerard K. O’Neill Memorial Award for Space Settlement Advocacy, thanks to his advancement of commercial space exploration through his company, Blue Origin.

The award was conferred by O’Neill’s widow, Tasha O’Neill. In the midst of laying out his company’s vision for the future of space exploration, which included colonies in space, he announced that the science fiction show was being picked up by Amazon Prime, Amazon’s subscription service that offers access to music, videos and other media. As Bezos said, to general applause:

“I was talking to the cast half an hour ago, before the break for dinner started. I was telling them that we are working hard at Amazon to save The Expanse but it wasn’t a done deal yet. During dinner, ten minutes ago, I just got word that The Expanse is saved. The show is extraordinary and these guys are unbelievably talented.”

The news quickly went viral and fan sites dedicated to getting the show renewed quickly responded. In fact, #SaveTheExpanse.com went so far as to declare victory:

“We did it!  Thanks to the incredible, historic efforts of the cast, crew and fans of the critically acclaimed sci-fi epic, “The Expanse,” the television show has been resurrected by Amazon Studios and Alcon Entertainment for a fourth season. Just two weeks after being cancelled by Syfy, the massive grassroots effort that followed the news achieved its goal in saving the series, which is now set to appear on Amazon Prime.”

Alcon Entertainment co-founders and co-CEOs Andrew Kosove and Broderick Johnson were also very happy with the fact that their show had been picked up by Amazon Prime. As they were quoted as saying by Variety Magazine:

“We couldn’t be more excited that ‘The Expanse’ is going to continue on Amazon Prime. We are deeply grateful that Jeff Bezos, Jen Salke, and their team at Amazon have shown such faith in our show. We also want to thank Laura Lancaster, head of Alcon Television for her tireless efforts. We are fully aware that this wouldn’t have been possible if it wasn’t for the staggering outpouring of support from the most creative, hardest working sci-fi fans around the world. From reddit campaigns to airplanes, we say thank you. It worked!”

Bezos also took the opportunity to honor Gerard K. O’Neill, a physicist and well-known proponent of space colonization. Among the many ideas he proposed for creating settlements in space, the most-well known is arguably the concept of the O’Neill Cylinder (aka. O’Neill Colony). This would consist of two counter-rotating cylinders in space that would rotate to provide artificial gravity.

Bezos also acknowledged a debt to O’Neill seminal work, The High Frontier: Human Colonies in Space. “Professor O’Neill was very formative for me,” he said. “I read ‘The High Frontier’ in high school. I read it multiple times. And I was already primed. And as soon as I read it, it made sense to me. It seemed very clear that planetary surfaces were not the right place for an expanding civilization inside the solar system.”

On the subject of O’Neill Cylinders, Bezos indicated that they are a good means for creating accessible space habitats. “For one, they’re not that big,” he explained. “There’s another argument I always make too, [which] is, they’re hard to get to. [If] we build our own colonies, we can do them in near-Earth vicinity, because people will want to come back to Earth. Very few people – for a long time, anyway – are going to want to abandon Earth altogether.”

It seems rather fitting that an entrepreneur who is dedicated to making science fiction a reality has chosen to renew a science fiction show. Clearly, Bezos is a fan, or perhaps he knows that fans of shows like The Expanse are also fans of his commercial space efforts. In either case, fans of the series are happy to know that there will be more seasons to come!
