SpaceX knows those little landing legs are the suck and probably won't care if it tips/falls over.

it was a methane leak ignited by the post-landing fire i think

Don't care. Landed.
So yeah when it's fully combusting, you're just expelling Carbon Dioxide, which is way cleaner and less-harmful than Methane:RulesForTheeNotForMe said:
Not that I actually care because global warming is stupid, but semi curious how much Methane/ CO2 emissions each one of these launches pushes out.
Surprised John Kerry hasn't flown his private jet down to measure it himself!
I think they mean after they turn it upright and decelerate, then they can land on one engine.PJYoung said:
Ah SpeaceX said they meant to land on 1 engine. Excellent. What a huge step forward.
Either it is methane collected from the atmosphere and converted to CO2, methane being a more powerful greenhouse gas, or they produce the methane by extracting CO2 to create CH4 and H2O and then burn it back into CO2.Decay said:So yeah when it's fully combusting, you're just expelling Carbon Dioxide, which is way cleaner and less-harmful than Methane:RulesForTheeNotForMe said:

CH4[gas] + 2O2[gas] --> CO2[gas] + 2H2O[steam] + 891kJ
Obviously it's still not ideal but all combustion is going to expel something. I don't know exactly how clean it actually runs and I'm sure there's still methane in the exhaust, but it's not that bad if I understand correctly.
Now the RUD is a different story, but as you can see you still get a lot of combustion!
