Power & Propulsion

NASA's Game Changing Development Program is developing new batteries, fuel cells and solar electric propulsion systems to move man and machine through space.

Thanks for this quality video. Makes me wanna work at NASA!

Id trade in my Naval career for any tour of deep space travel. This is one thing in my life I am envious with our younger generations.
To see how far we exceed in deep space travel in 100 to 1k years is so captivating. 
Nope I am not a treky fan lol.
Awesome vid btw ty.

if the tech of a solar array can be adapted into a "fabric" then you can have a larger surface area and also easy to have an automated deployment once deployed in space

Why u no have moar views? Keep up the good work! These videos are awesome.

Sound effects in space? Come on NASA!

Origami could be useful with the folding and unfolding of the solar arays.

anyone know what the device featured just after the 4 minute mark is? it is also the same device used as the thumbnail for the video. id assume a fuel cell based on the context, but anyone know specifically what it is so i can go read more about it

[peterzpictstube]

What about a nuclear device to provide industrial scale power to provide serious propulsion and electromagnetic radiation shielding?

nasa x you should use gold it's a super conductor

[MrSparker]

Wow, cubesat propulstion. That's going to be great.

[cooperman]

Momentum propulsion would be a game changer.

And you guys could save weight by taking your permanent magnets and slapping them together in opposite polarity in the to make them weigh less

[karmakarnaren]

this thruster can change the future :)

I know that NASA is intrested in the VASIMR engine and the fusion drive. But when are they going to send those to space? Both of them are way more powerful than a chemical rock and also uses way less fuel. A mix between them could cut the Mars trip down to, I don't know a week maybe.

Now, in pure efficiency, I wonder how a fuel cell attached to an ion engine compares to directly using the fuel as a propellant.

The only problem I see with this solar electrical power is that once you are past Mars' orbit, the output from your solar array is going to be diminished.  So how far out can it get before it runs out of juice?  Wouldn't a small reactor be a better idea?

[cynthiaayers]

If we could just find a way to use neutrinos to keep a battery system charged.?

[Kanti]

Since you push your craft forward and won't loose speed, can't you just put a generator inside your craft and once you're out in space have the ion drive push that generator to create a rotating movement? Have a generator with a permanent magnet with a voltage regulator on the craft to put out the KWA you want. use the solar panel to input DC voltage for the exciter field. just my idea, I'm not space expert so I don't know how current would react in space.

at what distance from the sun would this SEP tech be inneficient? :o

[losbellosa]

You know my propulsion does KN at early dev times and promises MN/GNewtons. Whats the holdup?
