There is not a single Rocket in existence that can get any payload of any responsible kind to Mars.

You keep ignoring the fact that there is tomorrow, next year, next decade, next century etc etc. You seem stuck in some mythical stone age of your own chosing.

There is no rocket on earth in existence today that can get anyone to Mars.

Read my previous comment.

So you have changed your mind? Good, we are getting somewhere at last.

Beece. You mentally do not comprehend what I'm talking about. You clearly have NO Orbital mechanics understanding what-so-ever.

Correct, I am a lay person, but to my credit I am able to read, and comprehend reputable scientific accounts, by others far, far more reputable and obviously knowledgable then yourself.

How many times do I have to tell you we CANNOT budget for the dV required to go to Mars.

You just said costs does not matter or more correctly, it isn't about money. You seem confused?

That's where it ends.

No it doesn't. Science, technology are advancing all the time. Any person of reasonable knowledge and not weighed down by an agenda knows that. We do not as yet have the means/technology to land a man on Mars and return him safely, or to create a colony where a crew maybe reasonably safe and sheltered from obvious dangers, at this time. There was also a time when our science and technology was not sufficient to create a space station or a scientific apparatus like the LHC. We have them now. With the ISS, as so often you have ignored, it is an international effort, and even more astonishingly, has been under permanent occupation every day of every year for 21 years or there abouts now.

And just as obviously again, you keep ignoring the fact that I, personally am not putting any time frame on either returning to the Moon, creating a permanent colony, attempting a manned mars landing and colony, but am simply saying it will happen as we, as science, as technology progresses and allows us to achieve these goals safely.

And also of course the final aspect with regards to costs of achieving these worthwhile dreams, [an aspect you seemed confused about ] I believe they should be done with an International effort.

Elon Musk can't get anyone to even the Moon. Do you think space travel is magic? Has anything changed since Apollo? Physics maybe?  Absolutely not. dV hasn't changed. Rocket engine thru

Boy you're naive. NASA gave money to Musk because Musk is now a billionaire and can tell congressmen to give him money.  The days of the US accomplishing anything are fastly deteriorating. 

Their, they're, there are sew so many weighs ways of getting it wrong. I just make sure I get it write.  Musk seems to think his Starlink revenues will provide the necessary funding.

Mars is not about cost because it's not physically possible. Moon is about cost. It costs about $30billion per moon-shot.

You literally don't know what dV is ... do you? Look up the dV budget then continue. It'll make more sense what I'm talking about.

Musk cannot possibly return to the Moon because Musk doesn't have $30billion to waste.

China or US etc are unlikely to do it. China might for prestige but US will unlikely go back to "keep up appearances".

As there appears to be an agenda afoot, particularly with the rather silly claims that Space-X and Musk have achiebed nothing, here are some real facts.

https://en.wikipedia.org/wiki/SpaceX

SpaceX's achievements include the first privately funded liquid-propellant rocket to reach orbit (Falcon 1 in 2008), the first private company to successfully launch, orbit, and recover a spacecraft (Dragon in 2010), the first private company to send a spacecraft to the International Space Station (Dragon in 2012), the first vertical take-off and vertical propulsive landing for an orbital rocket (Falcon 9 in 2015), the first reuse of an orbital rocket (Falcon 9 in 2017), and the first private company to send astronauts to orbit and to the International Space Station (SpaceX Crew Dragon Demo-2 and SpaceX Crew-1 missions in 2020). SpaceX has flown and reflown the Falcon 9 series of rockets over one hundred times.

SpaceX is developing a large internet satellite constellation named Starlink. In January 2020 the Starlink constellation became the largest satellite constellation in the world. SpaceX is also developing Starship, a privately funded super heavy-lift launch system for interplanetary spaceflight. Starship is intended to become the primary SpaceX orbital vehicle once operational, supplanting the existing Falcon 9, Falcon Heavy and Dragon fleet. Starship will be fully reusable and will have the highest payload capacity of any orbital rocket ever on its debut, scheduled for the early 2020s.

What I'm trying to tell you is OF COURSE technology may change over time changing the status quo.

We have theoretical propulsion schemes to do this.

What I'm proving to you though is Musk'a Oxygen-PR1 rockets can't get to the moon.

They just can't.

And NO CHEMICAL rocket, even hydrogen and oxygen rockets can get a meaningful payload to Mars.

That is physical fact. It's a brick wall of reality. No way around it.

What? 

Northrup Grumman, Boeing, Lockheed Martin, aren't privately funded?

They don't take telecom money to launch satellites? 

What a stupid claim.

What? North American Aviation, Now North American Rockwell isn't a private corporation? 

Another stupid claim.

NASA operated both Apollo CSM and Dragon Capsule. Stupid claim that SpaceX is first.

the first vertical take-off and vertical propulsive landing for an orbital rocket (Falcon 9 in 2015), the first reuse of an orbital rocket (Falcon 9 in 2017)

Other operators were smart enough to drop their rockets into the ocean.

Wait what the literal fuck?

Rockwell International, builder of the space shuttle isn't a private company??

 

These accomplishments are literally shit.

None of them are new.

And SpaceX has been massively funded by governments for 10 years.

SpaceX is using OTHER people's technology. 

Nothing proprietary.

Thrust vectoring required to land a rocket like Falcon 9 or starship isn't anything new and wasnt invented by SpaceX.

So all SpaceX did was do what others did and claim they are the first to do it without government funding which isn't true.

Because the Falcon Heavy has a certain payload it can put into GTO.

Therefore that is the MAXIMUM dV achievement per that payload.

That payload is half the weight of an Apollo CSM.

So let's assume you were flying to the Moon in a literal portable toilet, then you are only 1/4th the dV there. The difference of a GTO and Moon mission.

Do you not understand how expensive getting to Mars is in dV. Forget about money. 

I am familiar with the deltaV requirements for many orbital changes within the solar system. However, I shall not forget about the money. You made a specific claim that it would cost trillions of dollars for manned exploration of Mars. I ask you again, present your evidence. If you are unable to support one of your claims, then there is no reason for us to take seriously any of your claims. In other words, put up, or shut up.

This extrapolation based on payload costs based on the 2^5th payload to fuel ratio increase means that over $1trillion to fly to Mars is extraordinarily reasonable. 

I already presented my evidence quite well mind you.

If fuel to get a lander to Mars costs approximately 10million dollars. What's 10million times 2^5th to get a payload ratio of 3:6 to Mars?

Congrats you've successfully sent a shovel into Mars orbit at that ratio of 320million dollars per kg.

Now do it for 60,000 kg.

What part have I not already met?

I've provided citations of the dV requirements and constraints.

I've cited the known costs for known weights.

You're lucky we are just assuming everything is linear-scalable and not influence by R&D, low unit volume costs, and any other setbacks.

The raw linear scaling for a mission to Mars at 60000kg payload with about 3.4:6.6 payload to fuel ratio at current prices is literally a doubling of cost for every halving from the current ratio of 1.6:98.4.

So to get from 1.6% to 34% that's 5 doubling.

But only for a payload of about 1000kg.

So gotta times it by 60.

Price to get perseverance to Mars.

2.7billion.

2.7x 32x 60x billion = 5.1trillion Dollars. 

 

There's your rough FLOOR of getting 60000kg to Mars.

Oh and dying there. 

7 minutes ago, Area54 said:

Would you call filling your 2000lbs sedan with 200,000 lbs of gasoline to be...meaningful?

The reason the dV budget is so crucial is with chemical rockets you HAVE to have a ratio of less than 1.6:98.4 payload:fuel to land on Mars one way.

So you see the problems? 

Either we are launching 3.75million kg spaceship to Mars one way or we are finding a new type of propulsion we don't have. 

That's just fuel to payload ratio. Should we get into fuel to weight ratio problems? 

SpaceX has tried to drastically lower THAT ratio but for something meaningful we'd have to build and fuel everything in orbit to have no atmosphere to build structure to withstand

Like I said, while problems and current limitations may exist, these problems are being worked on as we speak, by scientists, engineers, cosmologists etc.

Entry Trajectory Options for High Ballistic Coefficient Vehicles at Mars

Abstract:

Future large-scale Mars surface exploration missions require landed masses beyond the capability of current entry, descent, and landing technology. Hypersonic trajectory options for large ballistic coefficient vehicles are explored to assess the potential for improved landed mass capability in the absence of landed accuracy requirements. Hypersonic trajectories appropriate for use with supersonic parachute and supersonic retropropulsion descent systems are studied. Optimal control techniques are used to determine hypersonic bank-angle control profiles that achieve favorable conditions at terminal descent initiation. Terminal descent initiation altitude-maximizing bank strategies for parachute descent systems are explored across vehicle and mission design parameters of interest. A tradeoff between altitude and flight-path angle at terminal descent initiation is identified. Hypersonic trajectories that minimize required propellant for propulsive descent are identified and studied parametrically. A hypersonic ballistic coefficient and lift-to-drag ratio are shown to have the largest effects on required propellant mass fraction; changes to the vehicle state at entry interface have a smaller effect. The space of reachable supersonic retropropulsion ignition states is presented over a range of vehicle and trajectory parameters. Overall, results indicate execution of an appropriate hypersonic bank profile can significantly increase the parachute deploy altitude for parachute descent systems or reduce the amount of propellant required when compared to full lift-up entry for supersonic retropropulsion descent systems operating at Mars.

Please stop trying to force down my throat and other reasonable  people that a Mars manned landing will never happen. Again for the umpteenth time, with a certain need for science, scientific exploration, and the simple reason of "because its there", in time, 10 years, 100 years, 1000 years we will have mastered a manned Mars landing, we will have a colony by necessity, on both the Moon and Mars. The world is full and has always been full of people who have sniggered and claimed this will not ever be achieved, that will never come about etc. Man achieved the first powered flight in 1909, now just a little bit over a 100 years later, we have landed on the Moon six times and are preparing to return and go further afield. Reminds me of another wise great scientist, Lord Kelvin and a now infamous [and silly] comment he made that went like this.....https://www.xaprb.com/blog/flight-is-impossible/

I can state flatly that heavier than air flying machines are impossible.
— Lord Kelvin, 1895

I have not the smallest molecule of faith in aerial navigation other than ballooning, or of the expectation of good results from any of the trials we heard of. So you will understand that I would not care to be a member of the Aeronautical Society.

This is a fallacy. The question is will Musk get us to Mars.

Obviously not.

And unless we develop a propulsion system vastly different from what we have now. We never will.

What incentive do we have to invent a new propulsion system? 

The Moon at least made a little since in the ballistic missile race.

No one is winning any prestige by getting to Mars.

It's too anticlimactic. 

3 day trip to the Moon is epic.

The technological gap between the stone age and going to the Moon is smaller than from going from the Moon to Mars.

The dV budget is deceptive. It appears so close but yet it is basically impossibly far at current scales of economy.

Perhaps if the US were 2 or 3x more productive than it is now, the hundreds of billions it would cost to brute force the dV problem for the payload masses involved could be justified. 

Until then, a technological solution must be discovered to change the status quo.

Even if true, SFN isn’t the place nor is your ranting and raving in this thread the proper method to work through your trauma. Professional therapy would be better if this accurately describes your situation and motivation.
