The rocket engine starts with a neutral gas as a feedstock for plasma, in this case argon. The first stage of the rocket ionizes the argon and turns it into a relatively “cold” plasma. The engine then injects the plasma into the second stage, the “booster,” where it is subjected to a physics phenomenon known as ion cyclotron resonance heating. Essentially, the booster uses a radio frequency that excites the ions, swinging them back and forth.

As the ions resonate and gain more energy, they are spun up into a stream of superheated plasma. This stream then passes through a corkscrew-shaped nozzle and is accelerated out of the back of the rocket, producing a thrust.

Such an engine design offers a couple of key benefits over most existing propulsion technology. Perhaps most notably, unlike chemical rockets, the plasma rocket operates on electricity. As it flies through space, therefore, it does not need massive fuel tanks or a huge reservoir of liquid hydrogen and oxygen fuel. Instead, the rocket just needs some solar panels.

Hopefully, by the time I get this, Trump and company will be a distant memory.

I'd read a tiny bit about this awhile ago, but hadn't seen them till now. I particularly like how dorky they look. I'd wear them as is.

As a childless observer, it sadly seems that most neighborhood friendships are birthed and dissolved as children are birthed and dispersed.

Beautiful and Horrifying

I imagine some conservatives will claim that at the 1:48 mark, it's obvious that this is just the result of a whale breaching, and that the claimed scale is exaggerated by a factor of 1000.
