It's been more than half a century
(Apollo 11) since we've returned to the Moon and worse, we don't have
a permanent base there. The Space Shuttle disasters (14 dead
astronauts) have taught nothing to the idiots and asses who believe
that rockets (the first CEO was Hitler) can be improved as the
physics incompetent Musk believes. I'll explain why: There is a
thermodynamic equation PV= NkT which links the speed of the gases
expelled from a missile to the temperature of the combustion chamber
(missile nozzle). That relationship tells us that the speed of the
gas with which the missile recoils is inexorably linked to the square
root of the temperature. At most the combustion chambers tolerate
around 3000 degrees of temperature. If you want to double the thrust
of a rocket the temperature must be raised to 12000 degrees! … No
metal alloy in the combustion chamber tolerates even 4000 degrees.
Therefore, any rocket, even an improved one, will NEVER have double
thrust with the same expelled mass. See the repeated explosive bangs
of Musk's starship trying to make comically bigger and more powerful
rockets.
Furthermore,
the rocket-based spaceship loses pieces during each journey. About
0.3% of the total starting mass returned from Artemis with a trip
around the Moon with the usual dive into the ocean. The same
percentage as the old Saturn 5.
Certainly rockets will never
transport minerals from the Moon and Mars except in homeopathic
doses.
Furthermore, rocket believers boycott any attempt to
scrap rockets as demonstrated by Chris Bergin's criticisms in

.
In summary, rockets are good for wars on Earth (short trips)
and also for putting satellites into orbit around the Earth and
resupplying the ISS station at about 400 km above sea level. But when
you force them to try their hand at distances 1000 times longer such
as the Earth-Moon distance (about 400,000 km) they demonstrate all
their inadequacy.
For years we have been witnessing Musk's
comical proclamations declaring he is launching astronauts into
space, omitting that they reach a maximum height of 400 km. And a
large mass of imbeciles applaud ecstatically.
