I'm not aware and I'm sure there's an answer, but has the starship ever landed on plain soil/rock on Earth? If so, can it do the same thing on the mars sandy/rocky texture? I can imagine the thrust produced when decelerating will tear a sizeable chunk out of the martian surface making the ground uneven If starship manages to touchdown do we know if it will stay upright or fall over?

Why would anyone wanna live on that shithole called MARS ??????
Comment from : Leon Hall

Parachutes have already been used on Mars, they just need to be bigger
Comment from : John Till

Thanks for your work, it's an encouraging subject
Comment from : Aonghus Devery

I know it's not the same thing, but the British built English Electric Lighting, was so short on space to put the fuel, that they even turned the flaps on the fighter Jet into extra fuel tank space They later added extra over wing fuel tanks on top of the wings, add even more fuel to the aircraftbrFinally, happy Christmas to you all from the UK br🇬🇧🇬🇧🇬🇧
Comment from : Gordon Fraser

Could extra fuel be stored in the wing flaps perhaps ?
Comment from : Gordon Fraser

Once again brilliant Thanks Marcus
Comment from : Duncan Booth

Also, the possibility of a mars gateway”, type of craft
Comment from : NOM

Let’s just get to the moon first and see what resources we can use There can possibly be a more efficient way to regulate the delta v to a possible new fuel A new type of fuel could change the fuel problem completely
Comment from : NOM

I think that cargo BFR’s should have, (I think they already do) have lager tanks for cargo ships, and possibly a different engine count and shell weight ratio
Comment from : NOM

Hey Marcus, your face looks soo high deff Did you get a new lights and camera system The production looks great
Comment from : Judah Datoy

The Apollo deadline was optimistic but they did manage to do it, space x will probably fail their deadline
Comment from : Samuel Zackrisson

Here comes starship V2
Comment from : Hector Keezy

Why not go sideways and have parachutes on one side and balloons on the other
Comment from : Dave Gott

I’d like to see a module with plasma rockets and fuel that could be carried up as Starship cargo and attached to a Mars mission starship This would provide more efficient and faster transit to Mars They could be discarded, or the module could detach and fly itself back to earth orbit for refueling and reuse Starship would hit Mars atmosphere faster, but a reentry tile system that can handle a return trip to earth from the moon should be able to handle it
Comment from : Edward Nutter

Millions of us had those same doubts from the get go
Comment from : R Christie

First tour guide tour of Marsthis is the first crash site second crash site third crash siteall proceeds to spacex
Comment from : Paul Murphy

Great video as always Marcus! So excited to watch this all playout for real
Comment from : Carl White

When landing here on Earth, the landing pad is a flat concrete pad Most photos of Mars I have seen show a very uneven surface Including many rocks How will Starship land on an uneven surface like this?
Comment from : Gordon McIvor

Would Flat landing a VTOL type craft with 4 corner engines with a much lower center of gravity be any safer?
Comment from : Kappy Kaiju

You need to include some tankers on the journey
Comment from : Nuff Said

you talk toooo fast and it makes unpleasent to watch your videos are you running away from someone? :)
Comment from : Lydia & Martin

I came here specifically for the legs!!!!! FFS
Comment from : TTheodorus Ibrahim

I liked this one more than the others, because I like to know the latest tech about how are we getting to Mars
Comment from : The Interfaith Shepherd

You kicked ass on this video, Marcus! Nice job!!brbrThe most amazing achievement I am aware of is the Manhattan Project The numbers around that are astounding They literally built cities and factories in a couple of months
Comment from : The Interfaith Shepherd

Looks like you guys have found The bone to chew on brExcellent explanation and definitely something to think about and watch Thanks Marcus!🖖
Comment from : Brown

Starship as we know it will never go to Mars, or the moon It will be used to launch payload to orbit around earth, re-enter the atmosphere, and land Any other space mission using superheavy booster will use a 2nd stage similar to starship but different, and specific to its mission (eg if it's not going to land on a planet/moon/object, and will never enter an atmosphere, the heat shields, a few of the thrusters, the wings, and header tanks, will not be needed) Reducing mass increasing payload and completely changing the ship
Comment from : Stokes Seegers

An extra 50 tons of propellant ? That’s half the so called payload
Comment from : SwiftRIBSAust

refuel,refuel,br refuel -piddling about with marginal fuel availbaleis incredibly short sighted - need to think outside the box!
Comment from : Denis Moran

19000 Litres(671CuFeet) only? Don't seem a lot 80m sec is 180MPh ! That's a lot of mass to slow down from
Comment from : Rasputin Putin

Would it help to enter Martian orbit before attempting landing from a slower velocity?
Comment from : Emil Fluornoy

I appreciate this content You do go deep which is great for me Also it has long life
Comment from : Chris von Schweinitz

Finding a landing site that would be level and solid enough may be difficult If there is any slope or rocks, the ship could tip over, possibly destroying, or, at least, damaging it and injuring or killing those inside
Comment from : William Burych

From our current physical, phsycological and technical level of understanding, i cannot support any conclusion that it is possible without considerable harm to any participants
Comment from : Steven Homan

Loved the episode Marcus ❤ Thanks to the entire team for putting it together 👍
Comment from : Stinger NSW

im curious how they exit the ship at such a height
Comment from : LorGreaver

Marcus thank you for the information This makes the whole starship endeavor all the more incredible
Comment from : James Simon

I like things like this its cool and interesting to me
Comment from : keith wright

If he flattens Starchip and makes the surface in contact with the atmosphere larger it will slow down more rapidly
Comment from : Flatjet

A Mars starship would be a totally new designed layout Many different designsbrCrewed and uncrewed would be totally different design, Fast and slow transit etc brYou don't even need fully reusable Why would you return a Starship
Comment from : David Watkins

Go Elon 😀go go go 🚀
Comment from : Simon S

If (or rather when) Starship passes all approvals, tests, orbital flighttests and finally is ready to get sent to Mars, I imagine the first ship to be unmanned, but sending an empty ship over seems also a bit of a waste If the ultimate goal is to colonise the planet, surely sending something usefull (yet somewhat expendable, in worst case scenario) would be a good idea? What will be the first possible cargo, does anyone know?
Comment from : Ben Huizer

when using mach as a unit of measurement in this case i would assume it was based on mach at sealevel on earth
Comment from : Markus Rubach

We only need the header tanks to flip the craft around and induce acceleration to make the fuel/oxidizer in the large tanks to settle to the bottom Many second/third stage (and Apollo) engines have tiny tanks for just such an issue So, no the header tanks, don't need to change at all, but main tanks still need to stay cool
Comment from : Matthew Kaiser

Still boggles my mind Why not reduce entry velocity “in-orbit”, gravity takes over, and your already coming in significantly slower, which means you need less Delta V on landing
Comment from : Gryphon Arms USA

Super interesting Thanks Marcus Re: new designs I was always sceptical SpaceX could keep the same design for very different planets/missions They soon required differences for the moon I think you can only stick to the same design if the margins are large and it seems they are very tight
Comment from : oyster catcher

FYI, the engines on mars are going to have an ISP closer to that of vacuum, so go with the full ISP of 356 or whatever they are estimated at now
Comment from : zilfondel

The way Elon would solve this is just to refuel the main tanks Have well more than enough for landing and don't worry about some boil off Perhaps have twice as much as you need and lose some through boil off during the journey and maybe the ships for the journey won't even have header tanks and instead use the space for supplies and crew
Comment from : graham grasdal

Landing on Mars is one of the most difficult achievements in space exploration Ask the Russians More difficult than Earth landings
Comment from : Terminus Est

So much for the first class cabin
Comment from : Jeff Fradsham

👍
Comment from : Donald Stewart

Thanks Marcus, great work Love how you explain things simply and without hyperbole
Comment from : Cedric Burg

So as of now, it’s impossible for SpaceX Starship to land on Mars, and a redesign is needed
Comment from : Jeff W

After watching the Vera Station video, you could easily push the envelope further and see the production facilities they envision in LEO could be used to make star ships, or parts of them, right out there in space Imagine if the Star ship wasn't tied down to the constraints of what a rocket can lift from Earths surface
Comment from : sp9rks

all they got to do is bring extra Fuel and decelerate before they even get to Mars
Comment from : Cheyne Simons

Would really like to see how an inflatable starship, might allow for single launch space stations, and make Mars aerobraking more viable
Comment from : Alan Chapman

Great topic 👍 Keep posting videos about the nitty gritty stuff
Comment from : nakfan100

Wil not be hard if nav sat`s marsbrHave laser guidance installed remotely, Piece of piss
Comment from : Ossie Dunstan

Lockheed martin will own space for the last war
Comment from : kuru

I tend to agree with the comment in the video Mars' atmosphere is not strong enough to slow a space vehicle down, but it is enough to destroy you when entering A Mars landing should be considered a Moon landing with the additional danger of re-entry velocity A fuel burn or heat shield will be necessary And drop the wings thing
Comment from : Miles Wilson

2:00 i thought the header tanks were only used to start the engines since in the belly flop orientation there might not be enough propellant in the pipes to get them started, but after the flip it should be pulling fuel from both header and main tanks, right?
Comment from : Matt K

Im just wondering about the infrastructure development, how will the materials be impacted, on the mars atmosphere Will the basics of building a foundation hete on earth still apply on Mars or how much of it will have to change?brbrI know it is a little different from the normal content but nobody is covering this 😅
Comment from : Christiaan Vorster

There is a possibility of using a single set of drogue chutes along with larger fin and spline setups to break the speed down some along with the tank sizes you estimated Consider all the different methods to land on Mars to date
Comment from : Waco Jones

Maybe the lunar retro rocket system in addition? Could be used to reposition starship after landing?
Comment from : otto von ottsville

No expert, but just off the top of my head, I would expect larger (possibly much larger) aerodynamic surfaces (aka fins)
Comment from : Gordon Stewart

Much larger "wings" (aero-brakes) might offset need for so much more propellant
Comment from : UnTwisted Truth

They may opt to use parachutes from the nose when using engines or from the side when gliding down, this would reduce the delta V required right?
Comment from : chris anderson

i'm not convinced that you would need to enlarge the header tanks especially on a mars landing my reasoning is this, you have much larger tanks available that can be used and would likely have been refueled in earth orbit before the trans martian burn they just can't be used for horizontal start up once you get the engines lit you could potentially swap out to the main tanks because the fuel/ox should settle before the headers run out bri'm just a mechanic so what do i know?
Comment from : rs10guy

Marcus, Would it be practical to send fuel and oxidizer towards Mars ahead of a Starship mission? I am thinking of a minimal vehicle that was basically just a couple of tanks with some minimal propulsion and guidance The idea would be for Starship to dock with the fuel and oxidizer supply while enroute to Mars and also on the return trip to Earth These tankers could be in a Mars transfer orbit between Earth and Mars and perhaps be refueled somehow Having additional fuel aboard Starship could allow for a quicker transit time and maybe a larger fuel margin for the landing Just a thought James
Comment from : JimJocrusin

Thanx for your excellent content Any concepts about the starship not flying alone? It is reasonable to assume that the “tanker starship” will have extensive solar power to maintain the active cooling required With its vacuum only raptors to achieve earth orbit could it also become a starship “service module” like vehicle to assist the mars lander starship in its interplanetary flight to mars Left in mars orbit to be available for the return to earth after redocking It would also seem logical that the mars lander raptors would be special for mars atmosphere and be not suitable for earth landing So do you leave the mars lander in mars orbit and use this service module(s) for the interplanetary journeys Dock with earth landers at this end
Comment from : Paul F

Catching up right before your next update! double Marcus Saturday for me! much <3 ty!
Comment from : Bee Sod

I’m sorry FAA, their excuses are lame, it’s all political and big money! I’m 75 and could have read the 18,000 submissions by now They also say a re-evaluation of the environmental review might take 6 mos Well it’s been 6 mos since they closed the comment period Now they’re just screwing with Elon because he purchased Twitter and SLS is such a failure They want the ULA and Bezo’s SLS to beat SpaceX’s first launch of Starship, but that is a impossible wish
Comment from : Dave Smith

Nice vid It's gonna be quite a ride for the first people coming into mars to land
Comment from : yoyoyoyo

Enjoyed the change from the normal rocket news, which has been a bit slow recently with starship on the ground
Comment from : allthingsnice1000

I was watching a starlink because of first stage and fairing half seperation being so close how don't they hit when the first stage has to make apagee Or do they get released after its apagee
Comment from : kale nash

How are they going land without a concrete pad wouldn't it dig a hole with those engines
Comment from : SirOverkil

Why doesn't the "Fleet" to mars just include a tanker ship Just refuel with enough fuel to land on Mars and skip the nose tanks all together Problem solved (I Guess)
Comment from : Eric Sabo

Why hasn't a standard been established for fuel and engine types? For example: SpaceX is planning to land and take off from the Moon and Mars But I don't believe they can resource the same fuel resources from these destinations Will the most successful company determine this or will different organizations establish their niche from this element? This might be a good video topic
