Rocket Cargo Tank contents exchange heat with atmosphere

After more testing I can tell that the only engines capable of getting Liquid Oxygen and Liquid Hydrogen from the Liquid Demolior Debris are engines with CO2 exhaust (Carbon Dioxide Engine, Sugar Engine, Small Petroleum Engine, Petroleum Engine and Biodiesel Engine). Even Radbolt Engine heated the liquids to above their boiling point.

And it only works without rocket chimneys, so you have to send rockets without tiles around them and without any backwall. It's also very much unwanted to have ~1200°C CO2 fly everywhere, so in practice something like Petroleum Engine would need like 5-7 empty tiles with 'Space exposure' to each side to avoid the hot CO2 touching anything. If you want to have multiple rockets landing with temperature sensitive material then they'd also need 5-7 tiles of space between them, or the exhaust of one of the rockets would hit the other. So now two rockets would take like 35 tiles horizontally (7 x 2 for the rocket platforms, plus 7 to each side and between them). All of this is terrible for anyone trying to build something in space.

All engines with CO2 exhaust exhaust CO2 at 990°C, except for Sugar Engine, which is even hotter at 1227°C, and Carbon Dioxide Engine which is actually -28°C, which absurdly makes it the best choice for gathering the most late game materials such as Liquid Hydrogen from space mining. I doubt the intention when designing Liquid Demolior Debris was space mining this POI using Carbon Dioxide Engines only, when they can't even have Spacefarer module + Drillcone + any storage, because they have too little height. Spacefarer module + Drillcone is 8 height, +2 from the Carbon Dioxide Engines is 10, so the limit of the engine.
