Nuclear Power in Space – How RTGs Work

Nuclear power is sometimes the best option for space probes and rovers to generate electricity. However, this doesn’t usually come in the form of a nuclear reactor, instead, it’s usually with an RTG. RTGs are used on many spacecraft, from the Mars Curiosity rover to the Voyager probes, including the recently approved NASA Dragonfly Mission.

  1. In space technologies need to hire lobbyists to get you guys money recognition you need a cheerleader

  2. No hard feelings please. You make great videos. People around the globe watch your videos. Those millions of people mostly need to understand the basic simple English pronunciation. This Irish-Aussie pronounciation makes it hard to understand 90% of th speech/narration. Kindly see if you can get a voice bot which would give millions of views. Thank you and good luck!!

  3. amazing how this info about voyager one isn't on wikipedia lol… thx for sharing

  4. ❤️❤️❤️❤️❤️❤️❤️❤️❤️ this is all I need in my life ❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️

  5. Nice. I love the art style and the more technical explanation.

  6. Excellent video, and amazing animations! I’d love to learn more about how you make these animations!

  7. Hello there! If you liked the video be sure to share it with anyone else who might like it. This was my first all animated video and the channel has come a long way since, so check out more some more Simply Space content and I'll see ya there.

  8. Nice job, the very obvious jump in quality is much appreciated 👍

  9. How do the semi-conductors regain electrons after they've all been used?

  10. Reddit sent me here and you just earned another subscriber. Good video, thanks.

  11. Great bro or sir i can't explain you are awsome…it's the great video that i was want to watch…💙💙💙lots of love for you😊

  12. Something doesn't seem right.
    You said that some semiconductors will be pushing the negative particles to the cold side. Those, I suppose, are electrons, which we need for an electric flow.
    Then you said that another semiconductor will be pushing the "positive particles" to the cold side. The only positive particles that I know that aren't positrons are protons.

    As far as I know, protons don't flow around a material like electrons do. The explanation doesn't seem correct, since in order for a side to become positively charged that same side had to become ionized, i.e. have electrons striped from the atoms and added to other atoms. It also doesn't explain why the first semiconductor becomes ionized, because the electrons aren't the only thing that jiggle more when internal energy is added. The whole atom is affected. In fact, this extra motion lowers electrical conductivity, as electrons have an harder time to jump from atom to atom in the lattice structure.

    The only way I could see this work would be through the energy and particles given off by the decay of plutonium, as this energy/these particles would have enough power to ionize atoms, stripping them of their furthest electron(s), creating that such electrical potential. But even this doesn't explain how those electrons would eventually move away or closer to the source of radiation, unless the orientation of the semiconductor wouldn't allow charges to move back to their respective ionized atoms…

  13. IF RTG brust in space can it effect human

  14. Sounds correct. Still desire more info and examples?

  15. Mind-blowing voice, explanation and animation too, which software do you used

  16. The way you speak, joke and structure your sentences makes me think you’re inspired heavily by Scott Manley. Or perhaps you’re his teenage son? 😜

  17. i have no idea what your talking about, but this is super interesting

  18. This guy is what happens when a ksp player learns blender and video editing and i love it

  19. Unfortunately not all countries are willing to invest in lifesaving tech but rather invest in nuclear weapon

  20. Excelente vídeo! Canal muito bom! Very good Channel! Contrats!

  21. Me when i unlock these in KSP: WELL time to spam it so i will never ran out of energy

  22. …we got lotsa heat from coming from the sun …why not use its heat and light for carbon free energy…never seen one only solar

  23. So Plutonium is used to generate heat, and a "reverse" functioning Peltier effect generates electricity?

  24. "Don't dig up the big box of plutonium, Mark."

    Nice video dude 🙂

  25. Are there different types of RTGs? If so, what are they?

  26. Why didn't you simply touch on how thermocouples work because of dissimilar metals? ie, copper/constantan (or others)?
    You could have shown a simple t'couple hooked up to a voltmeter, then show squeezing it between your fingers to watch the temp go up at the same time explaining the same thing happens many hundreds of time in an RTG simply by replacing your fingers with Pu and the output of the RTG as being the product of many multiple of this???
    Your molecular explanation totally missed the point.

  27. Is this what’s on the helicopter in Perseverance?

  28. They Use a Bunch if Thermo Electric Generators that is the semiconductor that you are talking about.

  29. Fake enviromentalists will hate this and will try to cancel Mars rovers

  30. Why are the particle moving down because of the fibrating?

  31. Tsss they don't release RTG FOR HOUSEHOLD USING

  32. Skip 10 seconds into the video to get a surprise

  33. What mass was lost? A neutron, a spare electron, a proton… what?

  34. Plutonium is also sometimes used in much smaller portions to heat spacecrafts

  35. Great content 👌🏼….. how long it took for the animation ?

  36. very helpful,fasttracked the idea for my tmrw exam

  37. Why we don't use this on Earth for our Nuclear waste
