    Another advantage is that they can pull gas that otherwise would be lost to cool the booster- and put that through a heat exchanger afterwards.

    Iain Banks' political stance has been termed "left of centre".[32] He was an Honorary Associate of the National Secular Society and a Distinguished Supporter of the Humanist Society Scotland. As a signatory to the Declaration of Calton Hill,[33] he supported Scottish independence.[34] In November 2012, Banks backed the campaign group emerging from the Radical Independence Conference held in that month. He opined that the independence movement was marked by cooperation: "Scots just seem to be more communitarian than the consensus expressed by the UK population as a whole."

    why is gateway propulsion and halo element (or power and propulsion element) to be launched by nasa on falcon heavy for gateway moon space station not first launched for iss to boost the iss us segment after russia retires russian iss segment and possibly deorbit them so that atleast the us segment remains in leo till a proper space station like axiom or bigelow are made, the propulsion an halo element on iss i think must work like zarya and zvezda on russian side that is to reboost iss like progress vehicles, the propellant will be transferred by a cargo dragon or cygnus or in near future dream chaser cargo variant and this may keep the iss us segment in place till around 2035 or 2040. moreover why the russian are leaving iss due to functionality problems like leaks in zvezda (like the reasons like making ross or lunar station with china) but thats the problem with russian segment no problem in us segment, i think propulsion element must be added to iss

    A full cryo test before a test fire would be smart. The partial test that was done did not fill the tanks as evidenced by the small/low frost line. Cold gas does not conduct/remove heat like filling with liquid. They need to cryotest all the welds with liquid nitrogen at the least before loading with liquid methane and liquid oxygen.

    having a gas expansion tank before feeding into an engine, could that be used in the future for more efficicent engines? you wouldn't be able to run the engine as hard or as long but you'd prolly get amazing specific impulse, especially if you aren't just blowing unburnt fuel into space

    • Kieron Taylor

      Once compressed to liquid state, an equilibrium is established where the liquid no longer vapourises because of a matching pressure from the vapour. As long as the tank can take the pressure of any vapour component the liquid will remain so. Heat increases that pressure, but as long as the tank contains it everything is fine and most of the content remains liquid. For cryogenic fuels/oxidisers, the problem will start to manifest over time because cooling things is expensive in vacuum, but vacuum is a good insulator and you can decouple your hot surfaces from your liquid tanks to an extent.

    Simplify, simplify, simplify. Musk uses the same logic by using an electric motor to power his cars. An automobile engine must convert vertical motion to circular motion. The electric motor is 90% efficient, although I wonder of the efficiency rating of the newest electric motor, I am sure the efficiency has improved, while the auto engine tries to run near 29/30% efficient. Some may say that this is not the same, however, when you remove complexity to do the same thing, you improve reliability.
