SpaceX’s Big Rocket – The Full Story
⚠First quick disclaimer the title above it's not my type to use those abusing names it's
up to Elon Musk who have said so in the interview because they have not yet decided name.
How come did Elon musk decided to build big rocket like this? as Elon himself told
waitbutwhy.com(which I recommend you to use for top rated stories explained clearly) he wants to make the journey to Mars be real not dreams
Why Mars?
Venus is a stupid, with its lead-melting temperatures, its crushing atmospheric pressure, and its unbearable winds.
Same deal on Mercury.
Jupiter, Saturn, Uranus, and Neptune are just huge balls of gas pretending to be planets.
Certain moons of Jupiter and Saturn are possibly habitable, but they’re farther away and colder and darker than Mars, so why would we do
that.
Pluto is even farther and colder and darker. Stop asking me about Pluto.
That leaves Mars.
If Mars were a place on Earth,
it’s somewhere no one would want to go.It’s cold but not that cold. It’s kind of dark but not that much darker than Earth.
It’s far but not that far. Its day is almost the same length as ours, which is nice for us and hugely helpful for growing Earthly
vegetation.
But going to Mars it is just that easy if you do not look in the window of finance or budget to go to the mars "Last
time the US Congress checked with NASA, the cost to send a five-person crew to Mars was $50 billion. $10 billion a person. Elon thinks that
to make journey to Mars affordable, it needs to cost $500,000 a person. 1/20,000 of the current cost.
;"That’s like looking at
the car industry and saying, “Right now a new Honda costs around $20,000. To make this a viable industry, we need to get the cost of a
new car down to $1.
So what the hell?
Here’s the hell:
Imagine if the way planes worked was that they took off, flew to their destination, but then instead of landing, all the
passengers parachuted down to the ground and then the plane landed by smashing into the ocean and blowing up. So every plane
flew exactly once, and to have a new flight happen, you’d have to build another plane.
A plane ticket would cost $1.5 million.
like in above comparison that why the tripss in space are expensive because
rockecks after the trip are crushed into oceans and this the challenge Elon Musk come to beat given that no one who
have tried it beforeand that's how we come to have this big rocket which is reusable like today's planes and this
at some percentage will make the journey to the mars with smart rockets to do more than one journey.
That leaves us with
somewhere between 19/20 and 199/200 of the cost left to cut. Part of that will happen when SpaceX takes 100 or more people to
Mars at a time, instead of five (the number Congress asked NASA about). The rest of it is taken care of by a few simple
innovations, like refueling the spaceships in orbit (which lowers the cost by 5-10x) and manufacturing propellant on Mars
so you don’t have to carry your return propellant with you (which lowers the cost by another 5-10x).
Here there is avideo which sums everything up deliciously!
