1. Imagine that it is slow as fuck…

2. It is fascinating! I am excited for the future.

3. The computer screen show java code _’

4. this thing launched in 98 and was decom’d in 2001. its old news, WTF?!?

5. Great four part series of videos. Everyone can see the challenges of space
   and how these pioneers over came them. This team did a great job and some
   luck getting the ion engine restarted, hey, they did and the rest is
   history. Only a brain dead would call it old news. BOB

6. Kerbal Space Programm ^__^

7. how can we best describe ion propulsion? is a mecanism that uses the
   electrons of the molecules and atom to generate power?? ion + and ion -??
   and what is the speed of it in light years.??

8. I like this source of energy because it’s not as expensive as “rocket
   fuel”, and electricity can be generated from pretty much anywhere. Static
   electricity, solar panels, wind turbines, nuclear power plants, water etc.
   Traveling on a more powerful rocket such as nuclear power would be good but
   as for traveling to planets like mars I would use electronic
   pulsion travel, sure it’s a little slow but that’s what E=mc2 is for, the
   speed of the spacecraft can catch speed of the orbit from the Earth, since
   Earth spins at 7,000 mph the spacecraft will travel at 7,000mph in addition
   to it’s speed alone which can be very fast, sling the craft and catch orbit
   from Mars. With electric pulsion at least you’ll have a never ending supply
   of energy to fly there and back without worries, if you attach solar panels
   of course. Always have a Cosmonautic medic on board.

11. 12 new tech that has not been test before.
    I see vulnerbilities

12. These things will probably outrun the Voyagers. I hope to one day see a
    mission to bring the Voyagers home.

13. Awesome documentary

14. what a loosy permanent annotation to the awesome video you’ve ruined effect

15. Thumbs up for damn sure.

16. Bad Ass without a doubt.

17. Nice presentation Nathan, what I liked best about it was that it sounds
    like you really have a grasp on the topic, rather than simply regurgitating
    information from your research.

18. 200,000 MPH like an inch worm in the desert. then I guess interstellar
    travel for human beings is out of the question even if you started it out
    accelerating with another high torque low speed engine like a liquid
    hydrogen/oxygen rocket or a fusion rocket and shifted into the ION drive
    later when decent speeds were attained.

19. Awesome! Yeah, I learned something, but the tricky part is retaining it.

20. Thank You, I did learn something, Nice work

21. its a really bad iron man repulsor

22. good presentation mate

23. cool beans

24. I did learn something. Plenty in fact. Thankyou.

25. You’re good at presenting

26. Thank You!!! I am doing a project also so you helped a lot!

27. Excellent presentation. Thank you.

28. Brilliant, thank you for sharing.

29. The acceleration is gradual, done incrementaly over a period of several
    months. It results in very high speeds.

30. A potted plant. That was excellent

31. I want to add that is good for space travel not for leaving planet with
    huge mass. So a ion propelled ship must be assembled in space. And load
    additional module to land on planet like Earth or Mars.

32. i laughed at “fuel efficiency of a Prius, top speed of a Lamborghini and
    the acceleration of a potted plant…” very good

33. there is no way , humans created this tecnology,, we cant see the ions,
    elctron , molecules… so the tech came from some where, an i cant
    compreend this…

34. good stuff

35. Excellent explanation – really puts the Ion Drive into perspective. Many
    thanks.

36. Hey, man, real cool video. You’re excellent at breaking things down so an
    average Joe like me can understand.

37. I like the bit about the potted plant.

38. makes sense

39. This operates very similarly to how I played around with the idea of energy
    weapons. Minus the magnetic fields to contain the projectiles.

40. Interesting video. Thanks for posting !!

41. arent the xenon atoms repelled by the postive grid?
