  • This tiny little wafer thin chip

  • could be a better way to explore space

  • than the

  • gold rush to space we can say

  • we're like the shovel.

  • Once upon a time Natalya Bailey

  • had big dreams of working for NASA.

  • I would sleep on my trampoline

  • at night and watch the stars

  • and thinking about aliens

  • and watching the Space Station

  • pass overhead

  • and I went on

  • to apply to NASA twice

  • to become an astronaut

  • and have gotten there thanks

  • but no thanks.

  • Postcards from NASA

  • but I'll keep applying.

  • So she had to settle for being a plain

  • old rocket scientist

  • and a founding member of Accion systems

  • a startup poised to revolutionize

  • space travel

  • with these wafer thin chips that believe

  • it or not our engines.

  • Low earth orbit is

  • becoming more

  • and more accessible to organizations

  • universities hobbyists

  • and their garages,

  • people that before never would have even

  • imagined launching a satellite.

  • So we're talking about you know

  • tens of thousands of satellites being

  • launched over the next decade

  • and currently they have no propulsion

  • solutions.

  • And that's what Accion is building as

  • is an engine that works on

  • small satellites.

  • OK this is actually rocket science,

  • so here's the bare minimum

  • you need to know- an ion

  • is a charged atomic particle

  • by pushing ionic liquid which is basically

  • a molten salt into this chip

  • the size of a penny billions of ions

  • can be discharged at mind boggling

  • velocities.

  • If you could picture an astronaut

  • sitting on the back of a satellite

  • and she's throwing tennis balls off

  • the back,

  • each time she throws a tennis ball off

  • the satellite moves a little bit in the opposite

  • direction. In Accion's engine these

  • tennis balls are actually ions,

  • and our smallest ion

  • engine is about the size of a pack

  • of cards.

  • Now we still need conventional rockets to escape

  • Earth's gravity.

  • But once in space Accion's chip

  • will increase the shelf life of satellites by

  • years,

  • and eventually enable deep space travel

  • without chemical propulsion

  • rockets. Our engines operate without any

  • fire flames

  • or loud noises so

  • they're not quite as visceral as say

  • a Falcon Heavy rocket for

  • example, but they're very efficient.

  • This is a Berkut.

  • It's a canard pusher

  • and it's kind of like our family car.

  • I've always wanted to

  • be an astronaut.

  • And aviation is kind

  • of like the next best thing.

  • Fortunately I married a pilot

  • and were raising the youngest pilot

  • here.

  • First electric propulsion engines

  • were actually developed in the 50s

  • and 60s

  • but they were largely ignored after that,

  • and it seemed to me during college that

  • there was this whole branch of rocket

  • science just waiting to be advanced.

  • Natalya's studies accelerated at such

  • a rapid pace she had to learn what it meant

  • to own a business while still a student

  • of science.

  • I don't think business comes

  • naturally to me.

  • I was in a lab

  • at MIT trying to finish up experiments

  • with headphones on listening to

  • how to be a startup CEO

  • and trying to learn on the

  • job essentially.

  • Our

  • serious long term customers

  • are right now people like the Department

  • of Defense and folks like Lockheed

  • Martin and Boeing.

  • But our first fight delivery that went

  • out the door was actually to Irvine high school.

  • So a group of high school students

  • is going to be launching a cube sat

  • with our system on it.

  • After hawking these chips to everyone from

  • school kids to the Department of Defense,

  • Natalya envisions Accion playing an even

  • larger role in space exploration.

  • Shoot for Mars

  • or

  • Alpha Centauri.

  • It's pretty a B Hag, a Big Hairy

  • Audacious Goal.

  • Is that sort of like your whole

  • career bascially?

  • Yes.

  • Why would you have any other way?
