Going to Mars.....

Have no desire to go or ability to go (age), but I admire the heck out of people like that. They are the pioneers. Look at it this way, without the explorers of the past they would have never discovered America, they thought the earth was flat and the explorers would fall off the ''sea cliff''. When you look at the sea, it LOOKS like there's an edge to it in the horizon. Can you imagine the courage (or foolishness) of those sailors venturing on, wondering if they would fall off that edge? I doubt that Mars will save our species, too barren and hardly any atmosphere and only traces of water and oxygen, and none of the other planets in our system seem to be candidates. The hope for our species are finding an Earth-Twin out in other solar systems, they've found thousands of planets already, a few MUST be like our planet.


So far the blueprint is spread algae over Mars' surface. After time when an atmosphere develops then pollute it with the idea the pollution will in essence, trap the atmosphere keeping it from leaving. It may be difficult to grasp what science will be capable of in the future but that is the reason people should read up on what the future holds. Know or believing it is all possible is much more exhilarating than just thinking it is a bunch of wild dreamers talking. It is kind of sad I won't be around to witness it all but just knowing what the future holds will suffice.
 

It is NOT a one way trip.
Yes colonizing Mars is the goal. Why? Because in a few million years the Sun is going to expand and suck the Earth in leaving no trace it ever existed.
We will build bases on the Moon so we can reach Mars on a regular basis without having to fight Earth's gravity.
So Mars will be our home as will other planets that will be constructed like the Death Star. Note, this is hundreds of years in the future. Buy the book Physics Of The Future by Michio KaKu for an intelligent review of what science is and will be doing in the next thousand years. Incredible reading from a leading theoretical physicist.

When the sun becomes a red giant our entire solar systems and planets will be gone.
 

I'm waiting for the aliens that created humans on earth to come back. They probably have really nice starships with first class amenities. I'll go with them.
 
The line of communiction will be an issue as the immense distance is a drawback. They will be on their own as there won't have a rescue vehicle. The scary thing is this is a first and so despite anticipating all there is to consider the human factor is the unknown variable.
 
Why would we want to colonise Mars? We need to invent Warp travel so we can colonise planets in other solar systems.But as we will be dead when the sun goes supernova it's not our problem.

Sorry but the speed of light is the limiting force in the universe . Warp travel? Not likely, neither is the speed of light available for travel purposes.
 
Why not? Do you think it will reach Earth and stop and leave Mars and the other planets alone?
It will consume only the two closest planets, Venus and Mercury while turning Earth in to a moltem ball . After that say two million years t will shrink to be a dwarf star.

I've read how new stars and their planets move away from the center of their galaxy and that our sun is now at the edge of the Milky Way. I've always wondered if that also happens with the planets in a system. In other words, are our planets moving further away from the sun, and will Venus one day be at the distance where Earth is now? I'm thinking that Venus is now at the same stage of Earth before life started, turbulent seas and toxic gases. And if that is true that the planets are moving away from the sun, then Mars used to be where Earth is now and someday Earth will be where Mars is now. Just a theory, I'm no physicist and have no idea whom to ask if it all makes sense. I'm sure scientists have asked the same question hundreds of years ago. Comments?

I suspect that no one really knows....and when we find out, it won't' matter.

Still in debate. Relativity says speed limited in a vacuum. But photons do not interact with Higg's particles and may not be limited. Newer experimental particles like Tachyons may have no limited either. That's the little-known subject of Dark Matter. Of course, this is theoretical. But, unless I'm mistaken. we have shown that there are galaxies moving away from us at fast-then-light speeds. We'll see --- I love this stuff!

The topic here is about colonizing Mars because Earth is going to disappear because of the sun's expansion. When that happens our entire solar system will be finished because there will be no sun emitting energy. Who knows what effect the gravity of the sun as we know it now will be like.

Wrong !......the topic here is going to Mars, the question was, would you go.

Last week's Neil DeGrasse Tyson's show he said now some are thinking some "things" are escaping black holes. If that is true that blows up everything.

More than one planet in our system had water on it before the Sun took care of that. Mars has an ice cap. The universe once thought to shrinking is expanding and the further out one goes the faster it is expanding. Theorists coined the cause of this as "dark energy" for lack of the reason for this expansion. I have not heard about your post on the galaxy changes so I have no comment. The questions on the universe just continue to grow. The more we learn the more we question.
 
Before we whisk of to Mars, we will use the moon as a test spot to develop the technology to live on Mars. Then it's off to Mars. Even if our present civilization collapses, future ones will pick up the gauntlet we have laid down, and go to Mars.

BTW I heard that the Chinese aren't or can't use the International Space Station. I know they have their own astronaut/space program. Does anybody know why they don't participate with the International programs?

I just looked it up, but this article is four years old. This below is just a paragraph in the article, read the full article if you wish.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The 2011 law draws a sort of ex post facto justification from a study that was released in 2012 by the U.S.-China Economic and Security Review Commission, warning that China’s policymakers “view space power as one aspect of a broad international competition in comprehensive national strength and science and technology.” More darkly, there is the 2015 report prepared by the University of California, San Diego’s Institute on Global Conflict and Cooperation, ominously titled “China Dream, Space Dream“, which concludes: “China’s efforts to use its space program to transform itself into a military, economic, and technological power may come at the expense of U.S. leadership and has serious implications for U.S. interests.”
 
Seems Mars wouldn't be the best target for a location where homosapiens has a chance to survive.

Dependent upon the mass of the original star, planets and their moons loiter in this red giant habitable zone up to 9 billion years. Earth, for example, has been in our sun’s habitable zone so far for about 4.5 billion years, and it has teemed with changing iterations of life. However, in a few billion years our sun will become a red giant, engulfing Mercury and Venus, turning Earth and Mars into sizzling rocky planets, and warming distant worlds like Jupiter, Saturn and Neptune – and their moons – in a newly established red giant habitable zone.
