Another great video! I only know very very little about rocket science but have learned alot just from this one video. You mentioned not understanding at first how lower molecular weight creates higher specific impulse, and I don't know at all, but does it have anything to do with when propelling a lower mass molecule you "use/waste" less energy to propel that molecule than you would need to use to propel a higher mass molecule and the fact that you only have so much potential energy to begin with? Also would I wonder if it would be possible to carry water on board a craft, then use electrolysis to split the water into oxygen and hydrogen? Then the water would be potentially serving double purpose for fuel and producing breathable atmosphere on board? What little I know about electrolysis you would need potentially sacrificial anode and cathode elements and a certain ph/chemistry of the water to produce clean H and O. Oh I just remembered the water would need an electrolyte to be able to produce electrolysis, so that could interfere with getting pure hydrogen and oxygen from the water... Yea I'm really hoping you respond to clarify this. Again great video, great work and THANK YOU for producing great content.

We don't need higher impulse engines. We need less limited thinking like in this video. Was the ISS assembled in a single launch? No. Then why is it assumed a Mars flight can only be fueled by a single heavy lauch? Jesus....just carry as much fuel as you need to get to Mars in pods in multiple launches. My dads truck can do this...why not a Mars flight. Musk shot his stupid car past Mars. But we can't make the conceptual leap to carry up fuel for a Mars mission in multiple unmanned launches. Also. Gravity simulation can be achieved via connecting two capsules with a long cable and spinning them. Easy enough. We don't need to torture astronauts with long months in zero g.

---Is it hard to make ion thruster? NO You can make DC plasma in the Vacuum chamber and shoot the ions out through the biased grid in the rage of KiloVolts. ---So why everyone's not making one? BECAUSE It is extremely hard to direct the ion trajectories towards the axial direction and get that theoretical perfect specific impulse. The repulsion among ions, chaotic magnetic fields due to accelerating charges, neutralizing the propulsion chamber, and many more that I don't know yet are just the tip of the iceberg.

Liquid Hydrogen is obviously best for nuclear-thermal propulsion. But SpaceX is shortly to be the world leaders in dealing with liquid methane. If the reactors could be powerful and light enough; CH4 should be able to achieve nearly 600 seconds specific impulse, which isn't lousy. LH2 needs huge, heavily-insulated and actively cooled propellant tanks (for long term). The same size tanks could hold a *really* big quantity of sub-chilled methane. On that basis; using CH4 might be an excellent compromise. But then; so might anhydrous ammonia.

To store hydrogen use water. Electrolyze water and you have oxygen to breath and hydrogen to exhaust. excess oxygen or CO2 could also be exhausted. Now add carbon as a solid or powder and you could make CH4 or any other hydro carbon. you have high power thrust when you want. You have coolants, you have a myriad of options.

What we need is nuclear power from fusion. Well, it is here in the form of the SAFIRE GENERATOR. Almost costless electricity and therefore hydrogen from new fusion nuclear is now immediately upon us. We have recently taken a new step to advance the physic of power production by enabling chemistry of the atomic nucleus, or "nuchemy" in the newest FUSION NUCLEAR POWER technology of the SAFIRE GENERATOR. We are passing the chemistry level where we interacted with the atomic electron shells and are moving on to manipulations in this "NUCHEMY" atomic nuclear era when we interact and multiply nuclear protons. We have rediscovered the lost work of the alchemists and can make new elements with different atomic weights. This was ably demonstrated in "The Safire Project". Quanta are important. We now have enough energy in them to manipulate the atomic nucleus much more easily by creating a compartment, or what is a local region of plasma containment so reactions at this atomic nuclear level can easily take place. This is about to practically enabled a really fantastic and cheap new era of energy production for the whole of mankind. This with hydrogen, so free fuel obtained from water or atmospheric moisture anywhere in the world. This new fusion nuclear is at the industrial commercial production final development point as of now. The energy argument and other power methodologies are all now virtually irrelevant as we have new and very physically and economically powered practical and local community level fusion nuclear power. Solar roof plus Teslawall battery may be the present way to go domestically but megapack batteries and multiple storage technologies interconnected with an expanded ugly grid have a less certain requirement when you consider new any-scale community based and 24 hr reliable and self-fueling fusion nuclear in the form of the "SAFIRE GENERATOR". Learn all about it at "aureon energy.com". Learn the newer EU Theory and plasma physics at "Thunderbolts Project.com" and you will be permanently reeducated with this advanced new EU theory that will allow you to understand more about the astrophysics of our whole universe and all within.

Why couldn’t you store the hydrogen as water, then use electrolysis to separate the hydrogen and oxygen as needed?

There are so many things we could solve with nuclear energy. The only thing holding us back is fear and ignorance. Yes, it can be dangerous. But if you think about it, just about anything can be dangerous if one does not take the proper safety measures. Your house can catch on fire because of bad electrical wiring. Your car can have a malfunctioning brake and that could result in a fatal accident. You can even find yourself trapped in a toxic relationship because your romantic partner hid their history of psychological issues from you. Regardless, possible dangers should only be accounted for, it should not stop us entirely.

Why not just store hydrogen as water.. your nuclear reactor can use water to generate electricity to separate the hydrogen from the water and I feel like extra oxygen isn’t a bad thing in space. Have the oxygen surrounding the tank of hydrogen so if any leaks out of the container it’ll bond with the oxygen and make water. Idk I’m sure there’s flaws to this. I’m just taking a stab at it with little knowledge of the whole deal.

Who would want to live on Mars? It doesn't have an atmosphere thick enough to burn up meteorite showers, doesn't have enough gravity to maintain bone health. The low atmospheric pressure, lack of oxygen and low temperature will require wearing a suit outside, which will get banged up, stinky and tiresome to wear. There's no magnetosphere to protect from radiation, no plants or animals to eat and no arable soil to farm. And worst of all, it's *FREEZING all the time.* Isn't that romantic?
