There's a movie I watch months ago about a company migrating hundreds of people from far away planet to start a new life they all put asleep while traveling and they have to travel 90 years, suddenly one of them just woke up, that's when the trouble begins
you can watch the trailer here: https://www.youtube.com/watch?v=7BWWWQzTpNU it's a very exciting movie we will have a good idea on how it is travel from other planets.

Who will be able to live on Earth once we nuke it into a burned out shell of radioactivity?

So who wants to spend their life on Mars?

We can send a team to Mars, and bring them back. I'd say to expect a couple deaths enroute, things happen. Colonizing takes massive robotics to do work that on Earth is done by evolution itself, so for colonizing we'd need a program of robotics and remote manufacturing well established before sending people.

Vertical landing was tested and perfected by the US in New Mexico in the mid 1990s.

He can spend his money on what he likes, but colonizing mars is probably just for publicity. Hes trying to make a commercial space program, he can make money in all sorts of ways, its as I said just a way to get attention. Most people don't know that much about Northrup Grumman, Aerotek, Lockheed Martin, etc but if they started claiming they were going to mars like Spacex they'd be a household name. There are an overwhelming number of unsurpassable hurdles to colonizing mars. If you just list them out you come to the realization that theres no way Musk actually plans on colonizing mars. Or I guess if he does, theres no way he expected anyone to survive.

We couldn't colonize the moon let alone mars.

In my opinion this is all a giant PR stunt, nothing more than massive stocks bumping action.
In case I'm mistaken, more power to him, it's always good to have dreams and challenging goals.
Why I think it is all smoke and mirrors? The simplest answer is; the propulsion system.
Small rockets and ships are always going to be the way to go off the planet BUT only for humans and other animals.
Cargo, parts, supplies need something else. Gaussian space gun, electromagnetic trebuchet, mass driver stuff like that. Inanimate and resilient objects don't care about g-force, without this in mind they will be stuck with astronomical costs of acheiving escaping velocity.
Electromagnetism is the only way to go, it is possible with today technology and yet they are completely silent about this.
This convinces me they are not all that serious about colonisation, if at all serious.

Commercial space(low orbit) sightseeing may be a completely different story and I think this is their real goal.  

Elon Musk wants the spaceship to be reusable,so if once their journey was completes then it will comes to earth and then take passengers to Mars and keep going?

I am personally moved by the space revolution started by Elon. I have seen various of his vertical landing rockets. I must say he is doing a great act for humanity.

I certainly believe that he will be able to take people to Marks, but o have doubt in date and numbers.
I million people is a way too much, and by 2025 is not just very far. I certainly want this to happen but i doubt on the dates.

Then why Elon Msuk is spending lot of his funds to build this idea? He even bought that company called Spacex to make his view possible.!

Unlike moon which is only a few thousand miles from Earth, Mars is around 20 million miles away and hence I believe any human mission towards Mars and settling there must be a one way road. Frankly, with the speed we are progressing, I don't these stuffs can happen by 2025 or 2050 even. Mars has no atmosphere and a lots of things to do before just sending humans to become Martians. It's almost 2020, nothing significant can happen in only 5 years!

The interesting thing about all this is that it is entirely possible to be on the way to Mars by 2025. Here's what I mean.

How much of the actual doings of Musk's operations do we really know about? Anybody can make deals behind the back of the whole nation, and even the media. What if SpaceX is only the transport system for some STUFF that Musk isn't talking about, but that will be ready for transport by the time SpaceX is ready to fly? In other words, what is going to be the main Musk cargo?

Now be patient with me, here. Because I'm going to sound a little funnier than usual. What if Musk's main mission is to send parts of a submarine into space? What? What am I even yammering about... submarine?

DuckDuckGo search on To the stars by atom bomb: - https://newatlas.com/orion-project-atom-bomb-spaceship/49454/. Back in the 1950s and '60s, the US developed a method to fly to the Mars and Saturn and back in a matter of well under 10 years. It had to do with riding the bomb-blast shock-waves of multitudes of controlled nuclear explosions. JFK and the military shelved the project because it was too dangerous back then.

However, if the "bomb rocket" were assembled in space, and if the bombs were set off when the bomb-rocket was sufficiently away from Earth that any possible fallout would be blown outward from the earth rather than into Earth orbit, there would be no reason to NOT exploit the capabilities of the bomb-rocket.

What does this have to do with a submarine? Check into the To the stars by atom bomb: story in the above link. Because of the power of nukes, the structure of the bomb-rocket would have to be made with submarine strength. But this kind of weight would NOT even slow down the flight of the bomb-rocket. Rather, it would enhance the size, so that a crew of 20 or more could essentially live in luxury during the flight.

To see some of the test flights done back in the '60s, search Yutube on "Project Orion nuclear propulsion" - https://www.youtube.com/results?search_query=project+orion+nuclear+propulsion.

Musk and Jeff Bezos might only be fronts for some group or government that are using them to promote distant space flight. We don't know what goes on behind the scenes. Just look at all the revelations made by Edward Snowden and Julian Assange that we would never have guessed about if these guys hadn't told us.



EDIT: Mars - https://www.youtube.com/watch?v=JtYisD7RqWk

There are numerous other pipe dreams from Musk, so that likely is the reason.There certainly are agendas. Musk has his circus-huckster approach, at the core his agenda is to sell rocket missions, primarily to government. NASA has one agenda pushed by their contractors, of finishing the SLS heavy launch system (Constellation) which would compete with Musk's heavy launch rocket.

At this time, the crew and service modules for the deep space missions exist. They have been flight tested, unmanned. The Space X heavy launch stack exists. One wonders why they can't be combined...

NASA's Lunar Gateway project is brilliant. It is a boost to both manned and unmanned missions as well as having the potential for sales of propellants mined on the Moon.

I don't know that its an agenda, just a poorly planned unachievable goal if you take the goals and timetables literally. Anyone with any sort of capability to actually get to mars would already know its a pipe dream to inhabit the planet, but its a nice concept to get the general public interested in space.

That's not even considering the issue of peroxides in the Martian soil, which seem to be a show stopper.

But they ignore all this and push forward with their agenda.

It absolutely will not be feasible in 2025. I honestly think we are a couple hundred years away from being able to solve some of the major challenges. There is so much that would need to be done to make anywhere else habitable. We simplify the basic needs of humans such that the plethora of supporting factors to those needs aren't accounted for. The life support features that came about on earth happened over hundreds of millions of years. We can accelerate that process with technology, but at major expense and still requiring a massive time frame. Transportation of essentials is a hurdle, radiation exposure is a larger hurdle, temperature is a problem, the magnetic field that provides the earth protection from solar flares and major impact from asteroids is lacking on mars, the list goes on.

With an infinite budget I do not think it would be possible to survive on mars right now or within any nearby time frame.

Yes,its similar to that preparing themselves for a suicide but still people want that too for fun.

It maybe too early for now but this is one of the untouched business market yet,Elon Musk want to take advantage of it and interested in making Billions ASAP because they are going to collect huge fee from every passenger of Mars.

I don't believe that his 2025 timeframe is realistic. Sure he's making good progress with rocket propulsion technology and space habitation.

However, he is yet to solve the challenges the astronauts will actually face on the martial surface... Particularly generating self sustaining amounts of energy and resisting solar radiation.

2030 looks more likely to me.

From what I have read about this trip to Mars, it seems that it is going to a one way trip so once you leave the planet, there is no possibility of ever coming back to Earth and with a lot of unknowns there is a high possibility that something catastrophic might happen but with all that said, we have to some risk because if it works out, it will be beneficial for all mankind.

I love the idea of space travel/colonization, but I'm skeptical about the economics of it currently.

Imagine it's the 17th century and Europeans learned of America, but America was a completely barren landmass with no plants or animals, just a ton of untouched minerals in the rocks. Maybe they could've imported some soil and plants in order to try living there, but there's no way that anyone would've taken the long and dangerous journey and invested so much in order to live on a barren rock. I'm not so sure that it'd even now have much population: consider that there's still low population density in difficult regions like Antarctica, northern Canada, and mid-ocean.

Space is that rich-but-barren separate content in the 17th century, but hundreds of times worse. Sure, we could move all kinds of stuff over there to make it theoretically livable, but it's not economically worthwhile, and the colonists are basically marooning themselves on a desert island.

Rather than trying to get people there ASAP, it'd be better to focus on technology which would boost the economic practicality of it, like:
 - AI & robotics which can independently do everything on Mars that a human might want to do, especially mining and construction.
 - Technology for passively & efficiently turning CO₂ + energy + water + trace elements into food.
 - A space elevator, mass driver, or incredibly cheap & safe rocketry systems. (But the above things are also useful on Earth, so I'd do those first.)
 
By the time a human arrives for colonization, you want to make it so that they don't have to do any work at all or rely on any imports in order to stay alive. Then they can focus on fulfilling & possibly-economically-useful activities like research, instead of on scraping out a meager existence on a barren rock with no real hope of ever being able to live comfortably.
