we need to be able to get off of her better
better
better so first thing we need to work out is
so first thing we need to work out is
so first thing we need to work out is how to very efficiently get off of Earth
how to very efficiently get off of Earth
how to very efficiently get off of Earth then we can start working out how to
then we can start working out how to
then we can start working out how to efficiently get on to Mars if you want
efficiently get on to Mars if you want
efficiently get on to Mars if you want to get off the planet Earth today you
to get off the planet Earth today you
to get off the planet Earth today you got one option build and fly a rocket

get that going
get that going the difference between a reusable system

you took a flight from New York to
you took a flight from New York to London and then at the end of the flight
London and then at the end of the flight
London and then at the end of the flight they threw away the plane imagine how
they threw away the plane imagine how
they threw away the plane imagine how much tickets would have to cost in order
much tickets would have to cost in order
much tickets would have to cost in order for the airline to make money
for the airline to make money
for the airline to make money it’d be like hundreds of millions of
it’d be like hundreds of millions of
it’d be like hundreds of millions of dollars per seat because they’re
dollars per seat because they’re

and millions of tons of cargo I
and millions of tons of cargo I conservatively estimate you’re gonna
conservatively estimate you’re gonna
conservatively estimate you’re gonna need a spaceship that weighs about a
need a spaceship that weighs about a
need a spaceship that weighs about a million kilograms you need about 10
million kilograms you need about 10
million kilograms you need about 10 times the NASA ship in fuel so now
times the NASA ship in fuel so now
times the NASA ship in fuel so now you’re looking at 10 million kilograms
you’re looking at 10 million kilograms
you’re looking at 10 million kilograms put into low-earth orbit to get all of
put into low-earth orbit to get all of
put into low-earth orbit to get all of that crap up into low-earth orbit would
that crap up into low-earth orbit would
that crap up into low-earth orbit would cost phenomenal amounts of money for our
cost phenomenal amounts of money for our
cost phenomenal amounts of money for our friends ISS cost I think it was about a
friends ISS cost I think it was about a
friends ISS cost I think it was about a hundred and sixty five billion dollars
hundred and sixty five billion dollars
hundred and sixty five billion dollars to put 380,000 kilograms I mean you do a
to put 380,000 kilograms I mean you do a
to put 380,000 kilograms I mean you do a math on that it was it was a lot of
math on that it was it was a lot of
math on that it was it was a lot of money per kilogram if you go to Congress
money per kilogram if you go to Congress
money per kilogram if you go to Congress right now and say like well it’s gonna
right now and say like well it’s gonna
right now and say like well it’s gonna cost us two hundred billion dollars
cost us two hundred billion dollars
cost us two hundred billion dollars they’re gonna say like well I think
they’re gonna say like well I think
they’re gonna say like well I think we’re gonna not do if you go to them and
we’re gonna not do if you go to them and
we’re gonna not do if you go to them and say like oh well now thanks to a better
say like oh well now thanks to a better
say like oh well now thanks to a better booster technology it will now cost 10
booster technology it will now cost 10
booster technology it will now cost 10 billion dollars well they’re like we
billion dollars well they’re like we
billion dollars well they’re like we spend that much on ISS every year we’re
spend that much on ISS every year we’re
spend that much on ISS every year we’re not gonna go anywhere or do anything
not gonna go anywhere or do anything
not gonna go anywhere or do anything until we drive down the price to
until we drive down the price to
until we drive down the price to low-earth orbit that is the key to
low-earth orbit that is the key to
low-earth orbit that is the key to absolutely everything then we can start
absolutely everything then we can start
absolutely everything then we can start working out how to
working out how to
working out how to efficiently get on to Mars
