On the engineering side at least the gaseous phase is definitely referred to as "steam" not "water vapor"
Saturated steam, superheated steam, etc

Yes, as in "Craft underwent rapid unplanned disassembly after an unintentional lithobraking maneuver"

>If you did not have atmosphere to slow you down on you way back you would need nearly as big of a rocket to land
So missions from a lunar post would still need quite a lot of braking fuel?

If Sci Fi movies taught me anything, it's that when a probe returns from uncharted reaches of deep space, lack of survivability is a plus, and is called sterilization.

What if we put it on a line?

A few things:
-
We were never guaranteed it would prevent transmission, the original trials were against symptomatic disease. Transmission data was gathered in real time as vaccines were given, and it's an imperfect science anyway. Many vaccines don't stop transmission including the inactivated polio vaccine.
-
We will always be a step in behind in vaccine updates because of the regulatory process, we updated vaccines to BA.5 and now XBB.1.5 is dominant. It's going to be this way.
-
It's not an argument, it's a fact it has reduced burden all you have to do is compare hospitalization rates for those vaccines and those not. Unfortunately many people don't understand base rate fallacy.
-
The increased risk of myocarditis has been acknowledged by every major health body. You know what else causes myocarditis, viruses. The flu can cause it. We know COVID-19 causes it.
-
The virus will continue to mutate away from immune responses. Herd immunity is definitely not here in the way many people use the term.

Nanotechnology as well. Wait until you hear about nanoscale microbots that can evade your immune response and deliver therapy or target specific cells.

Does that mean letting the ground do the breaking for free?

Say for instance you were a morbidly obese person, like 300kg+, lost the weight and got the skin removal surgery but then gained the weight back and then lost the weight and got the skin removal surgery again. Would there ever be a point that you run out of skin or would your body keep producing more skin?

In a pinch, they can also lithobrake!

If it didn't slow down at exactly the correct rate, it'd more likely miss than anything

The boiling point is just the point at which a liquid can no longer remain a liquid. It can become a vapor at much lower temps, below freezing even.

Good explanation though technically a dirty boiler does pass irradiated steam to the turbine. Such as those at River bend station in Louisiana!
