@@ernestgalvan9037 No vehicle costs just the fuel cost. In reality if you have to replace a part after say 100 launches. Then every launch costs an addition of 1/100th that parts cost. If you need to pay personnel to manage equipment for a launch then each person's pay needs to be factored into each launch. If you have ground facilities that need maintenance or parts replaced then a percentage of that costs needs to go into each launch. There is a good reason airliners have the majority of the cost in other areas besides fuel even though the plane is fully reusable. The only reason starships fuel costs will be more than 50% of the total launch costs is rockets are mostly fuel and oxidizer.

SpaceX isn't doing any type of Mars mission alone, I'll say that. Having a rocket big enough to get to Mars is a small step. They'll probably do test flights around the moon, have to create and rehearse a complex mid-orbit refueling...then preparing for ~6 months of transit, habitation, weather, dust, supplies, emergency plans, refueling in Mars orbit and launching off Mars... A lot of challenges. SpaceX is not a rover or habitat company (yet) so you can imagine the outside partners and NASA involvement to pull something like this together.

[@lordcraycray2921]

I think that a big part of this that you missed was the cost of the other consumables. While the Falcon 9 does indeed use a lot of Kerosene that can't be produced sustainably, it also requires hydrazine and a lot of helium which are expensive. Musk noted in a tweet that Starship will be much cheaper to fill because of that. starship will use methane/oxygen for rcs and will also recycle it to keep the tanks pressurized. I believe that ULA is doing the same with the ACES stage on Vulcan. With the cancellation of ACES and the statement that almost all of the objectives were achieved save for the piston engine powerplant, I'm not sure of Vulcan has achieved that or not.

[@AntonFetzer]

2:47 The methane concentration in the Martian atmosphere is only a few parts per billion. To collect enough Methane to refill a starship, you would have to condense a significant fraction of the whole martian atmosphere. Instead one would use CO2 and water to produce methane. The martian atmosphere is more than 90% CO2

[@zackb123]

@@_Super_Hans_ they would recycle the fuel (RP1/Methane) back to the tank farm. At Kennedy they might be able to recycle oxygen, but at Boca Chica it’s probably mostly vented out. The fuel is important to recycle because venting out methane/RP1 is bad for the environment, and the FAA performs assessments to limit the environmental footprint of launch operations. Additionally, they don’t want to leave an explosive combinations of liquids pressurized in the rocket for prolonged times for safety and so they can inspect the rocket if there’s a problem. Also, they super chill their liquids, and the fuel is coldest immediately after fueling, so SpaceX will always do a fresh fueling for each and every launch or test. And finally, leaving the fuels in the rocket will lead to constant boil off, to avoid blowing up they have to vent excess pressure, so you’re constantly wasting fuel by leaving it in the rocket. The cheapest and safest way would be to simply empty the rocket back into the tank farm, and refuel when it’s time to launch.

[@Markle2k]

@@j1b00m7 The F9 fuel is cooled for densification. It gets detanked along with the LOx. The densification is important for performance which is why Falcon 9s will scrub if a delay occurs after T-38 minutes when propellant loading starts.

[@fiveoneecho]

So, the propellent created on Mars will come from water ice and CO2 in the atmosphere (CO2 is most of the atmosphere). I'm not sure where the "Methane from the atmosphere" part came from as any Methane in the atmosphere is so trace that it basically isn't there- if there is any at all. Electrolysis is the process of separating compounds into component elements by running a current through them, so that is what is used to separate water into oxygen and hydrogen. As we should all know, you can't just magically pull Hydrogen out of nowhere to synthesize Methane, so that comes from water (in the current plan. If there isn't enough water ice, we will have to ship elemental Hydrogen to Mars for this propellent synthesis). The Sabatier Reaction or Process is used to synthesize Methane from Hydrogen and CO2. You put them in a pot, crank up the heat, and apply a bunch of pressure to get Methane with water. Just wanted to clear this up for anyone interested in the actual process SpaceX is planning on using for ISRU.

There is (almost I think) no methane in the martian atmosphere, SpaceX will make methane on mars using what is called: the "Sabatier process". In this process, SpaceX will take the *CO2* in the martian atmosphere, and separate it into carbon and oxygen, and will take the water ice from mars (H2O) and separate it into hydrogen and oxygen using electrolysis. They will take four hydrogen atoms with one carbon atom (obviously it won't be one molecule at a time), and create CH4, or methane. The leftover oxygen they can use for breathing, or for oxidizer. Using the resources you find at your destination is called: "In Situ Resource Utilization" or "ISRU". Just a small clarification about the video.

[@tauryus1]

Hi ! Great video as always However I noticed that, unlike in most of you other videos, you left out the conversion to metric units for volumes or pressures (see 4:20 e.g) It would be nice for future videos if you could include these units (as you did for temperature at 5:46) as they speak a lot more to people outside the US. Otherwise great topic, and very well explained and illustrated ;)

Do fuel suppliers add an Odorizer like what is added to Natural Gas to let crews know if there is a leak? Both LOX and Liquid Methane are colorless and odorless.

The whole intro sounds magnanimous but it's either talking specifically about SpaceX or it's referencing a space landscape that only exists because SpaceX paved the way. It's pretty much the same thing you'd get if somebody tried to frame the electric vehicle landscape as "competitive", or self-driving vehicles for that matter. Somebody came along and made it freaking _work_ (not just dipping their toe in the water), and now that people fully understand it's not merely possible but inevitable, they're scrambling to catch up. That's the real legacy. They wouldn't even be trying, without somebody making it happen first.

RP1 is NOT Jet A. It's a highly refined Kerosene blend that includes additives to prevent it from gelling in a cryogenic environment. Plus lubricity for the pumps and valving, to ensure none seize up while in operation. Other chemicals like sulfur and aromatics are removed or minimized, as they react poorly to certain metals in the engine assembly and make a poor lubricant in a high temperature environment. In the end, RP1 is twice as expensive compared to straight-run Kerosene. Some have tried Diesel blends and didn't get very far. Dr Goddard's first rockets used Gasoline.

I wonder if the methane that SpaceX buys has the artificial odorant added or not?

Agreed! Let's break it down... 0.36 - Fuel is not a major cost in keralox / methalox rockets, engine and booster cost is the major factor 2.50 - Methane does not come from the Martin atmosphere, CO2 comes from the atmosphere and may be reduced to methane 4.28 - LNG at 70psi is not a "relatively high pressure" relative to pressures in rocketry, CNG is ~3000psi. Helium tanks are similar. 4.27 - Increasing from 70psi to 100psi does not densify the LNG propellant, this is achieved by further cooling from 111K to 90K 5.29 - Air liquefaction does not occur at 100psi. It is compressed to ~100psi then decompressed in order to chill to ~75K in multiple stages 6.30 - Using the Sabatier process to produce bulk methane on Earth cannot compete economically with commercial fossil-sourced LNG.
