    So barring any other technology being used. Why Aluminum and not Titanium? Slightly heavier, sure, but at the same thickness, it would have been stronger. I'm sure something could have been sacrificed.

    No, NASA didn't reinvent the wheel, once again an idiot uses his stupidity to his advantage in naming his video. a wheel is a wheel is a wheel. changing the material it is made of does not change this extremely simple fact! Nasa used a new material for their WHEEL, same as they possibly did with the aluminium WHEEL.

For this reason, I do not even take into account some things related to details, because they are simple technological toys, created to work only on Earth.

    How do you set the shape it defaults back to? I'm not an expert, but I tinker with the reeds on my harmonica. In harmonica work there is a stage called 'gapping' where you adjust the height the reed sits over the reed slot. Lowering the gap makes the reed more likely to choke- to not sound- when you play with more force, but it makes it more responsive under light force, and that choking effect can actually be used to activate the opposite reed. Basically, by choking the reed you shut that 'valve' and force the opposite reed in the chamber to sound, which can give you pitches that you can't hit with either reed by itself (at least not in a two reed chamber). Overblows and overdraws give you more of the 'missing' notes from the chromatic scale that you can't get on a diatonic harmonica. Reeds worry over time and can break. With lighter playing they can last a lot longer but the holy grail for players is a reed that doesn't worry. One company does make stainless steel reeds, and for lighter players they seem to last almost forever. Harder players blow them out pretty quickly though. I think they may be pushing it beyond it's fatigue limit. Would nitinol make a reed that wouldn't suffer failure (or at least wouldn't fail for much longer), allow you to adjust the gapping, but then reset the gapping? A lot of the fine work of gapping is done well after the reed is originally stamped. How would you get it to keep the shape you wanted but still be able to recover?

    Very interesting video mate, but what you say @07:43 is incorrect. Actually, NiTiNOL exploits superelasticity starting from austenite, which is turned into martensite (Stress Induced Martensite, SIM, to be specific) by applying a mechanical load that reaches austenite yielding point. (Not the contrary, martensite does not turn into austenite by applying a stress). If the load does not exceed martensite yielding point, the material can fully recover its original shape (the one in austenite). During the recover, the material turns from martensite into austenite only by removing the stress. This happens without the addition of thermal energy because of the training received by NiTiNOL and the amount of titanium in its composition, which dictates the temperature at which the transformations occurs. Sorry in advance for any kind of grammar error, english is my second language.

    You should not be a Cancel for makeup so many facts, the Mars rover has an NPU Not a Nuclear Reactor. A thermocouple is not a nuclear reactor! It is cased by a something like (CE-214 like in your fire Dectector) that the Natural decay cases heat, this is a very safe tec, most produce Alfa Particles, in space, there is more radiation coming from the sun then this type will every produce( You cold theridical use something like Francimum or Coloradoan or thecnociam, but all would take more energy to make )

    isotope generator is pretty far from nuclear reactor. in reactor nuclear reaction is moderated, isotope generator just gathering power from decaying plutonium. main reason they used isotope generator is low part count, weight, bulletproof design and overall simplicity which is in strong contrast to infinetly more efficient but also infinetly more complex nuclear reactor. i really expected better research from youtube channel of this caliber...
