SpaceX Starship Rocket Stands Ready for Elon Musk’s Big Saturday Show

SpaceX Starship Rocket Stands Ready for Elon Musk’s Big Saturday Show


SpaceX’s Starship, the vehicle designed
to send humans to the surface of moon, Mars
and other distant destinations, is coming
together at speed.
Elon Musk is doling out more and more details
about SpaceX’s next Starship prototype ahead
of his big presentation this weekend.
On Saturday (Sept. 28), Musk will reveal the
latest design of SpaceX Starship and Super
Heavy.
The presentation will take place at SpaceX’s
South Texas facilities near the village of
Boca Chica, where the company is building
a Starship prototype called the Mark 1.
SpaceX aims to fly this vehicle for the first
time next month, on an uncrewed test jaunt
that will reach an altitude of about 12 miles
(20 kilometers), Musk has said.
The Starship is the most ambitious rocket
SpaceX has ever built.
It uses the Raptor engine, which uses liquid
oxygen and methane as its fuel, that will
enable astronauts to set up propellant depots
on other planets to harvest resources and
refuel.
The final versions of SpaceX Starship and
Super Heavy could start flying very soon,
by the way.
SpaceX representatives have said that the
duo’s first commercial flights, which will
likely loft communications satellites, may
launch as early as 2021 and a trip around
the moon in 2023, but from there the company
is aiming to establish a city on Mars and
potentially venture out further by establishing
propellant depots along the way.
It all starts with the Starship prototype,
set to be unveiled on the anniversary of SpaceX
reaching orbit for the first time back in
2008.
In this video Engineering Today will discuss
SpaceX orbital Starship: Elon Musk shares
rapid progress ahead of big reveal event.
Let’s get started.
SpaceX has made rapid advancements in the
week leading up to the event.
Elon Musk has taken to twitter to publish
yet more photos and video of the company’s
Starship Mk1 rocket prototype.
Wednesday (Sept. 25), for example, Elon Musk
tweeted out two photos of the partly finished
stainless-steel vehicle being lifted onto
a transporter.
And On Monday (Sept. 23), Musk shared video
of the raceway and flap hinge aero covers.
Musk has previously said that the Mk1 and
the Mk2 — a similar prototype being built
at SpaceX’s Florida facilities — will be
powered by at least three of the company’s
next-generation Raptor engines.
And Thursday (Sept. 26), Elon Musk has been
tweeting images of the vehicle, including
a view of its three Raptor engines installed
in the base of the vehicle.
This is the best official photos of Raptor
engines yet taken.
This marks the first time that a SpaceX prototype
of any kind has had more than one Raptor engine
installed, a fairly symbolic but still significant
milestone that follows in the footsteps of
Starhopper’s successful single-engine flight
test campaign.
This earlier prototype, flew Aug. 27 from
the site, ascending to an altitude of 150
meters before landing on a neighboring pad
a minute after takeoff.
That vehicle, won’t fly again, with the
company instead using it as an engine test
stand.
SpaceX Starship Mk1 is preparing to support
the program’s next major steps: full-scale,
high-altitude flight tests powered by three
Raptor engines.
“This is quite a complex beast, but hopefully
within a month or so,” Musk said Sept. 26
when asked on Twitter when he expected the
vehicle to make its first flight.
The sight of three Raptor engines installed
on the first true Starship prototype is undeniably
hard to downplay.
In barely seven months, SpaceX has gone from
the very first static fire of a full-scale
Raptor engine – serial number 01 – to
flight-testing Raptor SN06 and producing enough
engines to bestow Starship Mk1 with its own
set of three engines.
According to the latest comments from Elon
Musk, SpaceX Starship is meant to be powered
by three ‘sea level’ Raptors and three
vacuum-optimized Raptors – RVacs.
RVac may or may not be ready to support the
flight tests of early prototypes like Mk1
and Mk2, meaning that their three ‘sea level’
engines will likely be the sole propulsion
for the time being.
Both the Mk1 and Mk2 will start out making
suborbital flights, but the goal is to get
them to orbit eventually, Musk has said.
Note that the ship is just one part of the
vehicle designed to leave the Earth.
The final construction will include the Super
Heavy, a first-stage booster that brings the
whole construction to a height of nearly 400
feet.
The whole system is expected to use around
40 Raptor engines to provide the needed extra
boost.
Musk also provided some information about
the Mk1 on Wednesday, 25th September, in a
series of tweets, which addressed questions
posed to him by followers.
For instance, he said that this prototype
— the second Starship test vehicle, after
the single-engine Starhopper, which was retired
last month — is expected to measure 50 meters,
or 164 feet tall.
The entire mass of the Mk.1 ship is about
200 tons “dry,” or unfueled, and 1,400
tons when filled with liquid oxygen and methane
propellants.
But that weight should come down in subsequent
iterations, Musk added.
By the fourth or fifth iteration, SpaceX is
hoping to reach 120 tons of mass for Mk4 or
Mk5.
Including the maximum payload, the total stack
is expected to offer a mass of 5,000 tons.
In another tweet, Musk revealed the number
of landing legs the Mk1 will have.
The first prototype is expected to use six
landing legs.
That includes two windward, one under each
fin & two leeward.
Musk stated that this will provide redundancy
for landing on unimproved surfaces, an ideal
feature for a rocket expected to traverse
the solar system.
But where is the top half?
Musk explained that this component would be
fitted later.
The group did not close out the ship as it
was still building hardware into the top of
the fairing, which covered components like
composite pressure vessels and large batteries.
These have been placed in the nose tip, Musk
explained, to balance with the engines and
rear fins.
The ship uses four flaps to control pitch,
roll and yaw.
It’s unclear how SpaceX is moving the flaps,
but the company was spotted installing Tesla
batteries into the ship.
Musk’s electric car company, it seems, is
helping to benefit his other companies.
SpaceX engineers have installed 4 Tesla Model
S/X battery packs together, which would give
them an energy capacity of up to 400 kWh.
It’s the latest example of synergy between
Musk’s two main companies.
Musk often talks about the difficulties involved
in running two companies, but he also acknowledges
some advantages of being active in two different
industries.
SpaceX aims to dramatically reduce the cost
of rockets, and if there’s an industry who
mastered the art of making complex vehicles
cheap, it’s certainly the automotive industry.
On the other hand, Tesla has benefited from
SpaceX’s expertise of high-tech manufacturing
techniques such as stir welding, a technique
SpaceX uses to join large sheets of metal
like the ones used for the aluminum tank of
their rockets.
“It would be pretty embarrassing to use
a non-Tesla battery!”
Musk wrote.
It will result in more SpaceX technology inside
Tesla vehicles, while there will be some Tesla
technology in SpaceX’s own vehicle.
While SpaceX Starship will perform vertical
takeoffs and landings from both Boca Chica
and the Kennedy Space Center, where SpaceX
plans to test fly the Mark 2 version of Starship,
the vehicle will eventually be the upper stage
launched on a large booster Super Heavy.
Musk, though, said that developing Super Heavy,
will be less challenging to build than Starship.
The final, 100-passenger Starship, meanwhile,
will sport six Raptors, and the Super Heavy
will boast 35 of the engines — as far as
we know right now, anyway.
The plan might have changed; we’ll have to
see what Musk says on Saturday.
The presentation is set to cover a number
of areas.
Musk has hinted that it could include details
about how SpaceX plans to capture carbon and
create the Raptor fuel, which could help bring
rocket flights to zero-carbon.
He has also suggested the presentation could
detail its inter-Earth transport plans, which
would use the Starship to transfer between
major cities in less than an hour.
With a big list of ambitious launches planned,
the Starship team will be hoping for a smooth
first launch.

  1. What happend to the rule about not putting germs into space? Or is that only for spacecraft that are going to orbit another planet

  2. Since he's using Tesla batteries, he should design regenerative braking into his spaceships, that means he won't have to use much rocket fuel

  3. I cannot imagine how it is going to land on soft surface of the Mars or Moon with this current design. These tiny legs will sink into Martian soil.

  4. To test at 100,000 ft and 9000 ft/s : it has 12,000 ft^2 surface area. which puts it at about 120,000 pounds. total weight 150,000 pounds. it starts at 1.2 million pounds. average speed up is maybe 1000 ft/s. That uses 360,000 pounds. About 800 000 pounds are left to have a mass ratio of 8/1.5 = 5.4 which should bring it up to test speed and have some left over to land.

  5. Imagine all humanity was working with this single objetive we woukd be in differents solar systems already, just a bunch of people will take us to mars

  6. It’s a prototype or its the actual spaceship? I’m not a hater but I think the actual design is pretty ugly. I prefer the previous one because it suits our time

  7. This seems so unreal and ramshackle but perhaps that's just because I've been trained by NASA to expect prototypes to take decades and ultimately, never get built or when they are, be over-engineered. In comparison, this is gonzo engineering.

  8. Hey all of the fins are being controlled by electric actuation motors they found it electrical motors have a faster response time so their ditch the hydraulic motors and the hydraulic control actuator motors for the fins and have gone with electric for the fence in the kinnards at the top don't know if you guys know this already or not if you don't then I'm glad I can provide some information I want to go for a f**** ride so bad

  9. Anyone notice the Not For Flight sticker on the Raptor engine around 4:32 😆 Just how ready for testing is the MK1 prototype?

  10. what looks so amazing about the image at 9:45 is that the rocket is the size of the buildings in the background going space-bound!

  11. It would be better chances of success in sending 2 Starships at the same time to work together instead of 1…🔺🔺🔺

  12. When will the scientists and military come out with information that they have been working on since the 1950s on Antigravitics and zero-point energy ?
    All of this Rocket Ship building would be almost a moot point if the technology was brought out so that the best minds can work on it collaboratively and put the final touches on the technology that will really take us to the stars.

  13. Ваш поганый илон Маск прохендей и авантюрист впрочем как и вся ваша поганая америка

  14. The saturn v was only 2970 tons.
    5000 tons is probably for 35X200 tons engines so for 7000 tons of thrust.
    With 30X250 tons + 7*200 tons superheavy will reach 8900 tons of thrust so the whole stack would reach 6800 tons at takeoff.

  15. I thought finishing starship this fast was Bullcrap but I guess I was wrong. The people who built this so fast need a raise or something at least

  16. Thank you for making this video. You put the information in the video in a very easy to understand format and you convey the important information so myself and others don't have to stress keeping up to date with SpaceX. You could put a quick reminder in the beginning of the video to subscribe and like the video. I think it could help reach more people if you tried putting that in the beginning and keep the reminder at the end that you already have😊. Keep up the awesome work!

  17. "We'll have to see what Musk says on Saturday" I love that it came to this now, just constant discarding of bullshit and iteration

  18. At around 4:21 secs., I see a view of the Raptor engine showing several 'bolt circles' using bolts to join some flanged assemblies. That is a HUGE weight penalty! Properly designed Marman Clamp, Flange Clamp, or V-Band Clamp joints are capable of handling both mechanical and thermal stress concerns while offering CONSIDERABLE weight savings … just a suggestion.

  19. added … that many holes and stress-generating threaded features, add to the probability of failure analysis … as said, just a suggestion.

  20. lol…things don get interesting till humanity figures out self recharging electric motor but really gets interesting when they figure out the "magnetic drive sphere"…these are common things from my day…they, as a pair are called an "omni drive"…anyways…wait about 30yrs…i came here to this time to be able watch humanitys transition to the…how to say this…new era??…cant wait…here it takes like half a day to travel half the globe…in my day it takes that long to get to mars…like i said…very historic times…just wait…its coming

  21. Incredible achievement. In record time. Who the hell has the audacity to ‘dislike’ this? Flat Earthers have been through here I guess.

  22. Ahh man, makes me laugh every time I see people amazed at lighting dead stuff on fire to help throw crap into the sky as high as possible. Evolution works both ways, monkeys.

  23. Success would be an astounding result.
    Comparing any other non-wartime project with the sheer speed of this ship build is not possible.

  24. This is such an amazing space program for a civilian. It is highly likely that there is already a military “Blackout Program” with a base on Mars at this moment. I love it how he designed a rocket that looks like it’s from “Abbott and Costello go to Mars” 🤔

  25. Can you make your minds up – when l.pointed out last week the circumference at the base of the dome didn't fit the top of the fusleage – too small – it was pointed out to me it was a prototype. BUT NOW, IT'S FINISHED

  26. If you were travelling to the ISS you'd get EVERY moment on your phone – where are the astronauts leaked photos/vids from their phones 🤔 media would give smart money for those🤳

  27. You literally said the same exact things word for word out of an article i read online. I didn't know you didn't write your own stuff. Why did you copy other people's work?

  28. No way will be on Mars in 2024/25. If mankind have to go to Mars there be a multinational effort, but no SpaceX. Just marketing.

  29. (Said in my movie trailer voice)
    Sent from the future to steer humanity back on it's space ferrying coarse.
    Elon Musk brings us the Loony Tunes ACME rocket
    "Duck Dodgers In The 24th & a Half Century!"
