I honestly believe we would have more motive to go to Mars if there were beautiful, single women there.

If that were true, we have already visited that planet. Moreover, we would have already colonized it and make appropriate stations to live there)

Inertial drives will eventually make this a moot point, rockets are ridiculous for space travel!

Inertial drives...rockets are ridiculous for space travel!

Rockets are inertial drives!
- The inertia of the exhaust pushes against the inertia of the spaceship, accelerating both in opposite directions.

What sort of inertial drives were you talking about?

[cheeeezy]

the kind that are reactionless, and simply convert matter into force. yes it's easier to do than you think

Easy target to hit since I think that a reactionless drive is impossible, being a violation of conservation of momentum.

Such a drive would be an example of a non-inertial drive since all the ones we have (rockets) are inertial.

There are plenty here. The real question is whether Martian women are inclined to fancy ugly, stupid men.

The article proposed an alternative solution.

  Janhunen, an astrophysicist at the Finnish Meteorological Institute in Helsinki, described his vision in a research paper published this month.

He laid out the blueprint for floating “mega-satellites” around the dwarf planet Ceres, which lies roughly 325 million miles from Earth.

“The motivation is to have a settlement with artificial gravity that allows growth beyond Earth’s living area,” Janhunen wrote.

I found an interesting consept of the rocket engine and it`s called the hybrid rocket. The term ``hybrid`` has been given to this rocket because it combines solid Hydroxyl Terminated Polybutadiene (HTPB) fuel and 90% Hydrogen Peroxide (H202) liquid oxidiser. This rocket has been build by a private space company from Scotland and it`s called Spam rocket I wonder wether such consept be developed so, that it can travel humans to Mars. I know that there is the easier way how to do it but still it is an interesting point to think.

Some of us might be interested in what Martian men would be like.  They'd have evolved in a low-gravity environment.  Which allowed them to grow appendages of extraordinary dimensions, by terrestrial standards.

Isn't that a fascinating subject for speculation?

They also have to live in a dry environment with low pressure, low oxygen and high concentration of CO2 atmosphere. If we find Martian lifeforms, they are most likely microscopic.

That's disappointing.  I'd like a Martian with big dimensions. To conduct mutual investigations of our corporeal bodies.

So any attempt to fly it out of Scotland would be prohibited by Nicola Sturgeon as an inessential journey.
Why bother with HTPB? Hae ye no' seen the effect o' peroxide on a fried Mars bar?
Come to think of it, that would be the entire point of the journey. I rest my case.

Och, yon bonnie scots scintists, ye ken ma meanin hoots, are workin' on a grand rocket, powered by haggis-fuelled bagpipes. Hoots, an awa wi' yon Sassenachs!  Och aye, hoots, an gissum  more UK government fundin, ye ken?

Yeah, that`s a good point. I`ve already mentioned that. It would very difficult to survive there ( I assume almost impossible ) Building ISS near Mars might be the best idea. But still, it has it` own difficulties.

Average atmospheric pressure on Mars is 7 millibars, compared to 1,013 millibars on Earth. But the Martian atmosphere is almost entirely carbon dioxide. Compared with 400 parts per million on earth, giving a partial pressure of 0.4 mb, this is a factor of 30 richer for plant growth. So we need to import (or find) and conserve water, but there should be no problem growing food and thus generating oxygen in a suitable greenhouse. If we can find a source of hydrogen, even if it requires substantial amounts of electricity to dissociate a hydride mineral, we can then generate water.

That is why we are not ready for this yet. Without supplies humans will not be able to survive on Mars. To make these supplies we will have to make journeys to the red planet more often. Years and are needed to develop our technology for that

Couldn't our colonists get ready-made water from the Martian ice-caps?

I am not sure about that. To consum water from Mars we need to make a proper purification system that will allow us to use it. That is a good idea to figure out the water problem on Mars in case we colonize it but again, we do not have appropriate technology for that now.

[alancalverd]

You can distil water with waste heat from your body, or make a solar still. Fresh water on Mars begins to boil at 10 °C, and condenses rapidly with an average outdoor temperature of about -40. And for all we know, the ice caps may be inherently sterile or may contain something we could cultivate and eat if we moved it to the equator.

The northern lowlands comprise about one-third of the surface of Mars and are relatively flat

Colonisation of Mars is beginning to look like a job for a man with a tractor and a greenhouse - Essex Man!
