SpaceX, NASA, International Space Station, Falcon 9, Liquid oxygen 's Insane Engineering for Starship
To make that happen, he has created starship a fully reusable two stage to orbit super heavy lift launch vehicle. It is to date the tallest rocket ever built even surprising, saturn v, which was made by nasa starship, has generated a lot of hype among elon musk fans, prompting one of them to even create an animation of the starship launch from its reusability to its sheer size. Everything about the new starship is awe, inspiring and displays a level of genius weve, never seen in engineering how it works. The parts of starship at launch the spacecraft will sit on top of the rocket called super heavy. This combined structure is called starship. The whole thing will stand 120 meters or ‘4 feet tall with its nose, cone and landing fins. The spacecraft somewhat resembles the rocket ships in comics and old, sci fi movies and is no doubt an homage to them. The rear of the craft contains six raptor engines developed over the course of 10 years by spacex, the combustion happens in stages and the engines design cuts the amount of propellant wasted in the middle. You have propellant tanks that feed liquid methane and liquid oxygen to the raptors and the combination is called methylox. This choice of fuel is definitely not common for rocket engines, but methane can generate plenty of thrust and it works in a practical sense. Liquid methane can be synthesized from martian subsurface water and from atmospheric carbon dioxide, using a chemical process known as the savateer reaction, so the rocket can be refueled on mars for the return trip bringing mars a step closer to self sufficiency.
The super heavy rocket measures, 70 meters or 230 feet and will be filled with 6.8 million pounds of chilled methylx. This guy will be powered by 28 raptor engines, providing 16 million pounds of thrust. An engineering marvel hexiles first aluminum, then carbon fiber, then stainless steel and now hexagonal tiles. The starship body has seen quite a lot of evolution since its conception. Aluminum is a lightweight material and has been the go to for the manufacturing of every spacecraft after some launches. Under their belt, musk decided to give carbon fiber a shot, but that turned out to be way too expensive at least 200 a kilogram. So next on the list was stainless. Steel, though heavy it is incredibly heat resistant, its not a brand new concept. We did once try steel for the atlas program in the 1950s. Aluminum has a much better temperature tolerance than anything weve used before and would be the key to going to mars. We need something heat resistant because when starship enters mars, incredibly thin atmosphere, it will do so in a way that the amount of drag is increased to slow the vehicle as it approaches the surface. With drag comes heat and spacex plans to cool the rockets descent. Using a liquid methane pump under the surface, which will fight back against the heat, pretty much like how we sweat when its hot outside, but in typical starship fashion, they decided to come up with something completely new all by themselves.
In a series of twitter posts, musk revealed a glimpse at a spacex test of the hexagonal heat shield, tiles that will protect its starship vehicle as it re enters the earths atmosphere. Eventually, the heat shield will compose of several hexagonally shaped bits of ceramic shielding at times. During the test, the hottest parts of the tile withstood temperatures of 2510 degrees, fahrenheit or 1377 degrees celsius. Hexagons are a great shape for something like this, because it offers no straight path for hot gas to accelerate through the gaps. Soon enough, transpirational cooling will be added wherever there is erosion in the shield. This suit of armor should make it so starship is ready for launch almost immediately after it lands with minimal to no refurbishment. The fact that theyve managed to pull this off points to the genius in their engineering, the other materials havent been scrapped theyre all there. The heat shields are only to protect the starship vehicle, not the rockets as a whole, as it re enters. The heat shield is not meant for the super heavy booster, which is still made of stainless steel. The falcon rocket boosters, which spacex is reusing, are made of aluminum lithium and carbon fiber reusability. Another incredible example we definitely cant skip over is the reusability of starship rockets. Are incredibly expensive because they are typically single use, they burn up fuel in a few minutes and splash down into terrestrial oceans having put their payload on the right trajectory.
This is wasteful, not to mention its crazy that we discard some of the finest examples of human engineering and expensive materials to the bottom of the ocean, but for the longest time it was the only way to make them enter spacex. Their success marks a massive milestone in spacecraft engineering. If a rocket can be made reusable, this will allow massive cutbacks and expenses and thus ultimately reduce the cost of space travel for us at least thats. The long term goal for now. So, instead of discarding the principal hardware elements into the ocean, as the rocket re enters, the pieces will be recovered, the rocket will be refurbished and refueled to be re launched for another mission. Speaking of fueling spacex has already devised a way to fuel the rocket mid flight, just in case since you know, space has a serious lack of gas stations. The tanker starship variant is meant purely for refueling, other spacecraft already in orbit around the earth or in flight. After its done refueling, it will simply do a deorbit burn and fall back through the atmosphere to land on earth inside starship for a while, now, weve only gotten to look at the ships shiny, exterior it wasnt until 2019. That musk finally shared the interior of the stainless steel giant, and it gives us a pretty good idea of the massive scale. The very front of the ship aka starship has the payload compartment where people or cargo will be placed.
This part would detach from the structure as it reaches space and the super heavy rocket would flip over and return to earth. Then it would deploy its grid fins out the sides to help it carefully land back on the pad ready to be launched. Again, if were going to settle a million people on the red planet, we need adequate room and enough facilities to entertain them for the journey. The cruise starship variant features a 1 000 cubic meter, cabin capable of accommodating 100 passengers. The ship will have a common area, lecture halls, cinemas and restaurants too, the goal of starship we have to explore the purpose of the vehicle and why it needs to be airtight in concept and construction. It all started in 2002, when musk said that existential threats like an asteroid, collision or world war iii might be the end of humanity and moving some of us to another planet might be our only shot at preserving the species. Realizing this stream will need a vehicle thats up to the massive task. This rocket cube, spacecraft combo, can vary over 100 people at a time to the red planet and musks dream of planting. A million of us on mars will be achieved in no time and what a vehicle weve got. It enables not only travel but also production on a large scale. In fact, in addition to unbeatable concepts in engineering, spacex also manufactures rockets, like biscuit factories, churn out your beloved oreos.
Since 2010 rockets from the falcon 9 group alone have launched 114 times, they are the go to for nasa when planning their missions to the moon or the international space station. How is it possible for spacex to manufacture rockets so fast and at such enormous rates? Simple answer: exceptional engineering funding, even if elon musk has found a way to cut costs and make space travel more affordable to the everyday man. Starship still is incredibly expensive. So how exactly is musk planning to fund making thousands of starships for colonizing mars and setting up a base on the moon? Well, luckily, spacex has other ventures like starlink to help with this venture. The starlink project is an internet constellation that will provide the world with low cost high performance internet around the world. Once the project is complete, elon musk will see a return of 3 billion that should certainly help with manufacturing costs and lets not forget. They have quite a few contracts with nasa, so their government funding also helps out what started as a dream in 2002 is now coming closer and closer to reality and its all thanks to the engineers working day and night in the starship offices and facilities whats. Next, for starship, the date is always pushed back, but as of now, we can expect the first manned mission to mars to happen. Sometime in 2024., the cargo ships containing everything theyll need for living. There will go ahead of them in 2022, most likely using the cargo starship variant.
A ticket on the ship will cost you no less than 500 thousand dollars, but musk hopes that number will come down to 200 000 as they make their manufacturing process more efficient. The first settlers will live underground in tunnels made with elon musks own company, the boring company until a few giant corporations decide to come in and build some of their own skyscrapers and make the mars city musk has dreamt of. For so long. Think youll make a trip to mars on this ship. Tell us in the comments below and if you liked this video be sure to hit the like button subscribe and ring the bell.
