No human will ever return from Mars, or get there

[shockedcanadian]

We can get there. We can't return. Did you watch the video? Since on Mars, there are no supplies there, no system of carrying heavy loads there to deposit them, how will men on mars survive?

I believe for readers to understand; they need to watch the video.

That is a video for today. What about such a video in 200 years?

 

[Leo123]

If we do that, it risks putting people on Mars who won't be able to return. Tell me, did you watch the video?

Can men we send to Mars construct a massive rocket to return men to Earth?

There are some here on Earth I could support sending to Mars to never return.

Same here. Thanks.

Fuel is why. No returning from Mars fuel is there. Our best rockets take 9 months to get there. Those rockets never return. IT is a one way trip for anything we have. Who understands this? If you need more persuading, here it is.

Side comment, but gawd I hate those AI generated videos. Even if it is a from a real transcript. The accent on this one is hilarious. Sounds nothing like Feynman.

Very good point. I truly want to believe he is wrong. But his argument is compelling.

I think within a relatively short period of time - say 50 years - the days of liquid or solid rocket fuel will be as quaint as a steam engine to us now, replaced by energy sources we can't quite grasp now. And that speeds will take a quantum leap to the point where a trip to Mars might only take a couple of weeks.
Just guesswork on my part but I try to keep up with space travel and I think we're on the verge of some huge technological advances.

Is the voice important or the argument?

Not at all - that's why it was a "side comment". Sorry to interrupt.

And back in the day, they thought the Earth was flat and a ship would fall off the edge if I went too far.

I want to believe that too.

Now as to speeds needed. Are you proposing a rocket say 1,000 feet high?

As it is now, no. But someday man will harness more efficient and as yet known means of fuel and travel.

This is why I said watch the video.

I hope you are correct. Did you watch the video?

I want to believe that too. Did you watch the video. So far it seems I am the only person that watched it. He offers very sound scientific basis for his claims.

 

[Robert W]

It will be a lot easier to get to Mars and back when we have permanent bases on the moon. We can fly a bunch of rockets filled with fuel to Mars, land them there, and then the people we send won't have to carry the fuel to return home with them.

Will we build factories on the Moon?

I have not (yet). But I'll bookmark it to watch later.

I watched the entire video, and I must admit it is a pretty good video. But it has it's weakness.

He's absolutley correct that the rocket equation is a tyranny equation. And it isn't until the end that he begins to present an alternative with In-Situ Resource Utilization (ISRU).

That is the key.

When the Tyranny Equation says you can't do something you apply The Kobayashi Maru principal and change the equation.

I hope you are correct. Did you watch the video?

Yes. That's why it's clear the present-day model can't work.

Why wouldn't we?

Hey Robert, there is no need for me to watch that video nor no need for you to continually ask poster if they watched the video.

No need for humans to go to Mars.

Maybe in millions of years from now.
