Very interesting. So true.

The GOAT of SpaceX historical documentaries and a good introduction to to the next chapter of SpaceX; Orbital Refuelling. What if the kinetic energy of the upper stage of Starship could be ditched in outer space? The Kiss principle and "the best part is no part", could be applied to...

15/01/25 An Orbital Refuelling Space Station I admit I am an omega trying to copy the alpha, and I think that hanging all that weight on a rocket for it's return to Earth violates the principle of simplicity. Why pick the most violent environment; the last 100kms to ditch the...

A Slip-on Heat Shield Now that a rethinking of theStarship's heat shield is occurring, SpaceX must be tempted to swap 28,000 tiles for a Slip-0n Heat Shield that has been separately launched into Space. Exotic designs could be created without the weight constraints of having it...

(Reference: YT #Scott Manley "Data Centres in Space") Comment: "O'neill Cylinders or Stanford torus spring to mind." There are good reasons for such extravagance!

Really appreciate your interest to do the mathematics for me.

A KINETIC ENERGY CONVERTER (KEC) When material science improves, Starships returning to Earth will have a different heat dissipation. One that is efficient and simple. My suggestion is an additional outer skin on each section. A ten mm clearance is required to house thousands of nine mm long...

Acetone as a Rocket Fuel? This comment on the use of acetone is crazy. It seems that the energy density of acetone would be far too low compared with cryogenic fuels. However what if the Raptor engine had a pre-catalyst converter to release the two methane molecules and the oxygen and carbon...
