Well, Elon Musk is certainly great, Space X managed to remake the launch pad in half a year (which is actually not bad in itself, after the launch there are pieces of concrete from tables even cut nearby tanks, and the dust from the concrete spread for many kilometers), install a system for supplying water when the engines start and neither no less than to build another super-heavy rocket, having previously made serious changes to the design of the rocket, just adding hot separation steps. This basically requires quite a lot of rework, at a minimum hot separation means that the stage and the ship are connected by a truss spacer (to which they are attached using pyrobolts and something similar in any case) and on the stage there is a part that dissipates the jet and prevents the heat from the jet from heating the stage to dangerous values ​​(otherwise it will lead to explosion). Such a speed of work is unthinkable for state-owned companies, both here and in the USA. Such changes take years of work. And they screwed everything up in half a year, harshly. I remember they couldn’t launch the SLS for only a few months. They put it on the launch pad, discovered a hydrogen leak, removed it, then again, and they had such a mess from September and, in my opinion, until November. So here 33 engines were all working, which in itself is also very difficult, because with such work something that was not possible begins predict, as a result, the control system, in order to avoid an explosion, turns off the engine, and then another one so that the rocket remains controlled. Well done, but it’s hard for me to understand how people work at this pace. It’s true that they don’t have so many approval signatures.

In my opinion, the phrase “hot stage compartments” is a little strange. They use the hot stage separation method (in this method, the upper stage is turned on before the stages separate. Then only the stages are separated, and the engines of the upper stage go into operation. The engines of the lower stage are not switched off until separation. This is convenient because with this separation method we do not need to worry about the condition of the fuel in the tanks, there is acceleration from the engines, so the fuel will be at the bottom and will be supplied normally to the combustion chamber engine). And I probably wouldn’t call the steps themselves hot. Super heavy launch vehicle on a liquid rocket engine, and the liquid fuel is generally cold. Different fuels have different temperatures, but they are low. And the super heavy uses liquid methane and liquid oxygen (fuel and oxidizer, respectively). Methane has a temperature of -164 degrees Celsius, oxygen has a temperature of -183 degrees, they cannot be called hot. At Union, for example (there, by the way, the temperature of the fuel is much higher than that of methane, and kerosene has a temperature at which it becomes liquid -45 degrees), when it is fueled at the launch complex the color of the steps is white due to the fact that they are covered with frost due to the fact that there is a large difference between the temperature of the fuel in the LV tanks and the temperature outside. The engines are hot when the stages are running, this is natural; the temperature in the engine combustion chamber is extremely high, 3000 K (2726 degrees Celsius). But the engine is not the whole stage. In my opinion, it would be more correct to write something like “After the planned “hot” separation of the stage...”, because we are still talking about the method of separating the stages, and not the temperature of the stage.
