5:17: You were not wrong about RTGs being fission devices. All of the radioactive decay that heats those materials are in fact nuclear fission events. It is not stimulated fission, but it is fission, and you get the same total energy from the fuel whether the fission is stimulated or not, just at a lower power. The Seebeck effect has nothing to do with the nuclear side of an RTG. Any temperature gradient, regardless of source, can be used to power a Seebeck effect gnererator. In an RTG, nuclear is how you are converting fuel to heat and a Seebeck effect generator is how you are converting heat to electricity (in essentially a single step). In higher power situation it is more cost effective to use phase transition, turbines, and magnets to convert the heat to electricity (in a lot more steps). If you are going to call yourself wrong about something, please actually be wrong.

I guess Titan should be easier to land on than Mars (where the stupid atmosphere is too thick to ignore and too thin to supply ALL the braking you need), so if Titan's atmosphere is reasonably transparent to the radio frequencies they want to use, landing the main antenna makes more sense on Titan than on Mars.

Titan is an amazing learning opportunity, and possibly even colonization opportunity: Early Titan and early Earth appear to have been very similar. However, while Earth “took off,” Titan essentially went into the deep freezer!

[@goldenfloof5469]

Honestly it'd make sense to send up a relay satellite with Dragonfly so they wouldn't have to waste energy on the probe itself.

[@bluebrook32]

You’d think they would do that. It wouldn’t even need to be a very big satellite, and it would give Dragonfly more power and room for sciencey stuff.

[@ayonbiswas4186]

Yeah, placing it at Saturn's Lagrange points would give a permanent solution to the problem. Cause I can bet that after the Dragonfly mission Titan would eat up Mar's allocated resources.

[@philb5593]

Out at Saturn there is not enough sun light for solar power, meaning that this relay satellite would also need a RTG, however, plutonium 238 is in short supply, and is reserved for only the most necessary circumstances.

[@goldenfloof5469]

@@philb5593 Well, despite the fact that a solar panel would receive 1/100th the energy at saturn, that wouldn't exclude it from possibilities. They could use light weight mirrors (like a solar sail) to reflect light into a solar panel. Making it easier to fill the few hundred square meters of sunlight needed to power the relay satellite. Of course this is all speculation, and odds are they won't end up using a relay satellite unless it has some other use. For example, a satellite meant for scanning the surface of titan. But in that scenario, they'd most likely warrant giving it an RTG or two.

[@stevemickler452]

@@goldenfloof5469 This is often overlooked. A thin film solar concentrator mirror on the Titan orbiter could produce ample power at low mass penalty and beam that power down to a drone from orbit via microwaves in addition to comm relay. For a given mass power levels could be much higher.

A bit correction if you don't mind. The Radioisotope reactor also base on nuclear fission. Every radioactive material will decay, or "fissilized", for lack of better word, If left by themselves. The nuclear reactor enhance this process by either slowing down the neutron or enrich the fuel to a higher level or both. Now radioisotope reactor on the other hand, tapped into the natural decay process of the radioactive material. Also, Rather than using coolant for heat transfer, the reactor use seebeck effect to generate power.

THE CHILD WHO UNDERSTOOD GRAVITY Her name was Sarah, Sarah N. Dipity. As a child Sarah often overheard her parents, who were scientists, discuss gravity. They'd often bring Sarah to their office, where they did experiments about gravity and discuss them with other teachers and scientists. They assumed that she wasn't able to understand them, but in fact Sarah understood more than they did. It was frustrating that she was too young to talk. All of them said they didn't really understand gravity, which was why they were doing all that work. Somehow Sarah DID understand. She watched them try their experiments, draw on blackboards, and discuss things well past supper. Sarah realized, like them perhaps, that if someone could describe what she knew that it would be helpful. But she also couldn't write. She watched the adults head off in so many wrong directions. She worried that they'd try to teach her incorrectly, insisting that she learn their ways, which were often wrong. So, Sarah decided not to speak or write, which caused her parents to think that she was slow. She was perfectly pleasant, just silent. In her mind she continued to do thought experiments, using her knowledge of gravity. (c) 2016, Scott Myers all writes preserved

"RTG is not nuclear fission .... it uses a simple effect to generate electricity". The key difference from a nuclear power station is that the RTG plutonium decays slowly through release of alpha and beta radiation, and not a fission chain reaction. There is no possibility of an explosion due to uncontrolled fission. How the subsequent heat is converted to electricity (Seebeck effect or steam turbine) is another matter. Sorry to be pedantic on a splendid episode, but there is much public confusion all things "nucular".

@@isaacflett1321 yeah but it's not the sunlight that's the relevant factor in neutron activation gamma spectroscopy. For something like the mercury orbiter this is easy, all you have to do is use a gamma ray spectrometer on the spacecraft to look at the energy of individual gamma rays coming from the surface of the planet to deduce the composition of the rock and soil which is neutron activated naturally by high energy solar wind and cosmic ray particles smashing into atoms on the surface all the time. The collisions produce neutrons and the neutrons are absorbed by adjacent rock atom nuclei converting them to a different isotope with a short half life that emits gamma rays at a known energy. For a lander on the surface of Titan with a thick heavy atmosphere shielding it from cosmic rays, you have to bring your own neutrons to activate the regolith yourself to then allow gamma spectroscopy to be done. Sunlight is superfluous, it never factors into any of it.
