How do the mechanical properties of 301 stainless steel, carbon fibre composites, and Aluminium-Lithium alloys compare?
This is not an answer since it does not deal with the temperature range part of the question, but the graphic can't be presented in "comments"
For aerospace design, specific modulus (...

Was Starship’s “launch window” administrative, rather than due to orbital mechanics?
In the latest episode of What about it!?, the host claimed that a cruise ship was scheduled to enter the area (presumable to dock in the Port of Brownsville) later in the day, and that this was the ...

Was Starship’s “launch window” administrative, rather than due to orbital mechanics?
To add to what Dragongeek said, there is a road in Boca Chica that must be closed for launches. So disruptive is this closure, that Elon Musk has considered building a tunnel near the launch site for ...

Is vacuum created between the inner engines under Earth's atmosphere that could affect the booster in the early moments of the ascent?
My thoughts are that if there's isn't a pressure relief to the innermost engines they could create a vacuum
Your thoughts are basically correct, though the effect is probably less dramatic than you ...

Why Spacex Starship is not a modular rocket?
The main factor is the intended full reusability, with short turn-around time necessary to perform the orbital refueling for departure to Mars.
Falcon Heavy is an outlier, a Kerbal style contraption ...

During Starship's recent flight, the stack appeared to be venting gas during the staging sequence. What was it?
There are quite a number of gases that are vented out the engine section:
After the fire in the engine bay which caused a lot of problems during IFT-1, there is a CO₂ purging system for the engine bay....

Was Starship’s “launch window” administrative, rather than due to orbital mechanics?
Besides the "physical" constraints of launch windows (orbital parameters, technical limits like fueling), keeping a launch window "open" is also associated with a large fiscal and ...

Did Starship Ship 25 burn up on re-entry?
Yes, at least some parts definitely burned up
From what we know currently and what was said on the official SpaceX webcast, Starship was around 30 seconds away from SECO when the FTS system was ...

(How) would the water deluge system impact Starship superheavy captures?
In addition to the arguments in the other answers, there is an additional one: the landing will happen to the side of the OLM, not on top of it, so there is no water deluge system there. Since there ...

(How) would the water deluge system impact Starship superheavy captures?
There should be little problem with catching Superheavy from a deluge perspective.
During landing Superheavy will only have three engines burning and these will be throttled to zero very shortly after ...

(How) would the water deluge system impact Starship superheavy captures?
We don't know anything specific yet, but we can surely speculate.
First off, the landing thrust will be much lower than the launch thrust, as instead of whole stack filled to the brim with fuel, we'll ...

Why doesn't the BFR/Starship have a launch escape system?
Elon Musk has been mostly vague about launch escape on Starship, but he has indicated that he expects Starship to be reliable enough to not need it, other than a possible capability for the ship (...

How is hot staging of Starship expected to provide such a large (10%) increase in total mass to LEO?
The main benefit is that the second stage never stops accelerating, retaining close to maximum acceleration at all times.
One of most significant losses in rocket launches are gravitational losses; ...
