SPACEX STARSHIP WILL TRAVEL TO THE MOON!! Starship news and updates. Cryogenic test and 150m hop

Hey guys what's up! It's Simone here and this is the Future AwaitsUs.

These days great progress is taking placein Boca Chica Texas regarding the SpaceX Starship project.

The SN4 prototype is preparing the staticfire test with 1 raptor engine and then it will be the turn of its first flight, andeven if it's only a 150 meters hop, it will be a memorable moment.

Many people are waiting to see Elon Musk'snew creature come to life! In this video we will try to understand whatit is, where we are with the Starship project and what its next important steps will be.

We also have great news about it at the endof the video! But first I would like to tell you that thischannel has just started, so if you are interested in space, technology and science, don't waitany longer and hit the subscribe button on the right corner of the screen and don't forgetto click on the bell to activate notifications for the next videos.

Thank you and let's dive in! Elon Musk's biggest dream has always beento make humans a multiplanetary species and his plan to colonize Mars has already startedfor several years.

Almost 50 years have passed since the lasttime man set foot on the moon and for Elon it's an inconceivable fact.

Actually for me too.

At this point we should have already had alunar base, space tourism, perhaps even space hotels.

Instead, there have been backward steps.

NASA hasn't even launched American astronautsfrom American soil for years.

Elon knows that it's up to him to push thepace of space progress.

He is worried by the idea of ​​not beingable to fulfill his dream and he recently tweeted: “Good progress, but 18 years to launch ourfirst humans is a long time.

Technology must advance faster or there willbe no city on the red planet in our lives”.

This is why on September 28, 2019, Elon showsthe world the first Starship prototype in all its size.

With a retro look that looks like it cameout of one of those old 60s movies, but oh boy! how much I like it.

Let me know in the comments if you like thenew shiny version or if you prefer the old carbon fiber version.

Starship features After years of planning and many changes to the design, the final look seems to be somethingcompletely different from any other project ever made by SpaceX.

Built entirely with 301 stainless steel, accordingto Elon the choice of this material was the best for the project.

This choice goes against the trend comparedto those recently made in the construction of rockets, in fact the project initiallyexpected the use of carbon fiber due to its lightness.

Steel on the contrary is a very heavy material.

When it comes to rockets, every gram counts.

The heavier the rocket and the more thrustit takes to lift it, therefore more propellant.

The more propellant you add, the more therocket weighs and therefore you need more propellant and .

.

.

you got the point.

So why this change so radical? The answer was given by Elon during the presentation.

At cryogenic temperatures, 301 stainless steelhas approximately the same strength as aluminum lithium.

Unlike many types of steel, the 301 at lowtemperatures becomes almost twice as strong and in extreme heat conditions it becomeseven stronger.

It has a very high melting temperature thatis around 1500 degrees Celsius.

This means that there is no need for the heatshield on the leeward side when returning to the atmosphere and the protection neededon the windward side, the hot side, is extremely reduced.

This makes the 301 stainless steel rocketthe lightest reusable structure possible.

Furthermore, steel is very easy to weld anddoesn't need to be painted.

There is also another extremely importantfactor when it comes to large-scale production, the economic cost.

Carbon fiber costs around 130, 000 dollarsper ton.

while 301 stainless steel costs around 2, 500dollars per ton.

I think that the reason for this choice isnow much more evident.

But let's see the characteristics of thisgiant.

The starship is the second stage, the upperpart, and is completely reusable.

It has a diameter of 9m for a height of 50mwith a payload capacity of more than 100 tons, reaching the largest load volume of any currentor developing launcher.

The starship can be configured both in thepassenger transport and in the cargo transport version.

This system is designed to ultimately carryas many as 100 people on long-duration, interplanetary flights.

It has 3 sea-level engines and 3 vacuum engines, for a total of 6 Raptor engines.

The first stage instead, is called Super Heavyand has a diameter of 9m and a height of 68m and the beauty of 37 raptor engines and 6landing legs.

The two stages together reach a height of118 meters.

It's 7m more than the famous Saturn V rocketand 25m more than the statue of liberty.

When it's said that size matters! Starship's plan According to Elon's plan, starship will serve as an interspace transport with the abilityto reach the moon, mars and even explore the rest of the solar system.

But for now let's stop to Mars, seems enoughto me.

The best time to embark on a journey to thered planet occurs once every two years, when the orbits of the two planets are locatedat the closest point.

Despite this, the trip would last around 5months, although Elon expects it to be reduced to 3 months.

The spaceX project currently provides fora first launch into Earth orbit as early as 2020, but the first trip to Mars is scheduledfor 2022 with a cargo mission, with the aim of landing 2 cargo ships that will serve tocarry the material necessary for future expeditions, as well as placing mines, energy and infrastructurefor life support.

It will also be necessary to identify thepresence of water and possible dangers.

The second expedition is scheduled two yearslater, in 2024.

This time with the presence of the first humans.

Two crew ships and two cargo ships will bepart of the expedition to bring additional materials and supplies.

The goal is to build a base on Mars whichwill be expanded with future missions until reaching 1 million people by 2050.

A propellant production plant will also bebuilt, because the raptor engine uses liquid methane as propellant together with the liquidoxygen.

This type of propellant was chosen on purposebecause all the necessary resources are present on the surface of Mars.

Methane can be obtained from water and CO2through a chemical reaction called the sabatier process.

Furthermore, methane is inexpensive and sincethe starship is completely reusable, the costs would concern practically only fuel and maintenance.

A further important step of the starship, before sending the first men to Mars, will concern a project called Dear Moon.

In 2023, the Japanese billionaire Yusaku Maezawawill be the first passenger of the starship and together with other 6/7 artists he haschosen, he will travel around the moon.

The billionaire recently launched a contestto find a female life partner willing to travel with him.

So ladies, if your dream is to see the moonup close.

Current situation and next steps The covid19 has stopped many activities in the world but not the SpaceX which continuesto work at a fast pace.

In this regard, if you are interested in havinginformation on the future that awaits us after covid19, in the recommended videos I put theprevious video which deals with this very topic.

In Boca Chica Texas, the pace of buildingand testing the starship prototypes is impressive.

Various prototypes were built and tested ina few months, with spectacular results.

SN1 literally exploded during the cryogenictest.

The SN2, although not structurally complete, passed the test while the SN3, which was thought to be ready for the 150 meters first hop, instead collapsed on itself during the cryogenic test, this time for a human error.

Now the difference in economic cost between301 stainless steel and carbon fiber is definitely clear.

Before they started testing the first starshipprototypes, Elon had released an interview in which he said: “When trying different thingsyou've got to have some acceptance of failure.

Failure must be an option.

If failure is not an option it's gonna resultin extremely conservative choices and you may get something even worse than lack ofinnovation, things may go backwards.

” well said Elon, well said! The SN4 has finally passed the cryogenic testand you can imagine the relief of the starship enthusiasts, Elon tweeted: “Haha true.

Great headline.

It's quite hard to have rocket test articlesnot explode, as they so desperately want to!”.

Currently the main focus is on the SN4 butat the same time they are already working on the SN5 which is almost complete and nextweek they will probably start working on the SN6 as well.

As you have seen, the structure of the SN4is not complete, the upper part is missing, but according to a Elon's tweet, the headertanks and the nosecone will be present on the SN5 and perhaps also the flaps, whichinstead will certainly be present in the SN6.

The first hexagonal ceramic thermal protectiontiles were installed on the SN4, in different positions of the starship, using differentfixing methods.

This will be necessary to test the effectsof vibrations on the tiles during a flight test to determine which is the most suitablefixing method.

In the final model these tiles will coveran entire side of the starship.

The next important step will be the much desired150m hop that will mark a huge milestone for the starship project.

Another next step will concern the belly flopmaneuver, that is the maneuver that the starship will use to re-enter the atmosphere and slowdown the speed.

When asked if he was confident of a successfulfirst attempt, Elon replied: No, good chance of RUD (rapid unscheduled disassembly) event.

I really love this guy.

The speed with which SpaceX is proceedingreally leaves breathless.

At this rate we will be able to see the firstorbital flight very soon, probably already by 2020 and I can't wait! And in all this there's huge news! SpaceX has been selected with others by NASAto develop a lunar optimized Starship to transport crew between lunar orbit and the surface ofthe moon.

As you can see this Starship is very differentfrom what SpaceX is testing in Boca Chica.

This will be developed exclusively for theArtemis program.

Great days and intense emotions await us, with the colonization of the moon and Mars, the journey has just begun.

I would like to thank LabPadre for givingme the opportunity to show you the videos on the starships.

If you want more updates on the starship Irecommend you take a look at their channel, because they really deserve it.

I put the link in the description.

That's it guys, write in the comments whatyou think about and if you believe or not in the timing established by Elon for themars colonization, and if you liked the video, leave a like and subscribe to the channeland help me grow it quickly! Thank you and see you in the next video! SN4 prototype has.
