SpaceX Starship Thread

Laughing at the irony of a guy that says he's saving the world with electric cars while using lots of fucking humongous methane spewing engines to push a hunk of steel into space. Guess he can't afford the good hydrogen engines eh?

The most polluting engine since the Saturn 5. It burns methane, the worst greenhouse gas of them all.


A very good article explaining that between manufacturing single use rockets vs the re-usability of Starship and it's payload capacity will make it one of the best performing ships environmentally.

But compared to even a small player in CO2 emissions, like the airline industry, rockets currently do not even compare at all! We would need several orders of magnitude more launches to even begin to need to factor in their contributions compared to other industries.
 
Fun fact: the space shuttle RS25 engines still being used by NASA to power the new launch system produce nothing but water vapor. They have almost exactly the same power and thrust as the Raptor engines only they cost more.

He got cheap. That's all there is to it.

Hydrogen is perhaps the cleanest burning fuel. When you burn hydrogen with oxygen, you literally just get water vapor.

But there is a trace amount of nitrogen oxides aka NOx while the vehicle is in the lower atmosphere otherwise known as the troposphere as an after-burning effect of the hot flame coming in contact with the air. Literally all rocket engines will do this to a certain degree when in our troposphere, which is primarily composed of nitrogen."

All in all though, the NOx is classified as a small amount early in flight so environmental point to you.

Water vapor is actually a much more powerful greenhouse gas than CO2. You can think of CO2 as more of the thermostat and water vapor as heater, kind of.
 
I just wished they spent a fraction of their time and money fixing real fucking problems rather than adding to an already untenable pollution problem for the sole sake of selling space flights to millionaires.
 
Well, between Bezos and Musk alone they could have already wiped out child poverty in the entirety of north America with just what they've blown on rockets to take 10 minute trips.

So, yeah. You have a point.

It's part of the reason I support what is known as a a Robinhood Tax or a financial transaction tax, which has actually been proposed in your congress a few times since 2009/2010.
 
Right now Biden is 0 for 6

$15 minimum wage: No
Economy that works for everyone: No
Police reform: No
Rich pay fair share of taxes: No
Hold previous administration criminal accountable: No
Medicare for All: No

He and democrats at large did what they always do: Make a bunch of promises to get elected and then trash it all and go do what they want.

Republicans will be back in charge again next year because of it. Count on it.
