NASA - Get yo ASS to MARS

The rover and orbiter pics are cool.

BUt can we just get are asses to Mars, and back to the Moon. Besides some of the other planets moons, those are the only two places in our solar sytem that are visitible.

Mercury - practicaly parking itself on the sun.

Venus- extreme crushing gravity, and acid rain

Earth - (oh wait we're already here)

Mars - Lets do it

Jupiter, saturn, neptune, uranus - are believed to not even have a surface. If anything pure liquid and gas

Maybe you could give us some reasons that going to Mars is worth the millions (billions?) of dollars that it would cost? Why is that money spent best on putting a human being into such a hostile environment? What scientific data could it provide?

wall-e might be there

Stephen Hawking thinks that colonizing Mars is possible, but even if the atmosphere was changed for human living, gravity would still be the only problem. After several years of living on Mars, a person who return to Earth wouldn't be able to stand. And if they tried, he said, they'd probably break a lot of bones.

Well it's not like you would need to go back to Earth once you terraformed Mars.

True. A permanent exodus.

Em, Venus's gravity is less than Earth's.

He probably means crushing pressure.

is that why aliens are all slender and small.. low gravity in their planet?

what about building domes and under ground facility with increase pressure by pressurizing of gasses?

You can't terraform Mars until you find a way to restore it's magnetic field. The reason it lost its atmosphere in the 1st place is that it had no magnetic field due to the fact that there is no planetary dynamo as this stopped 4 billion years ago. Once it stopped the solar winds from the Sun just blew the atmosphere away as there was no protection from the magnetic field.

The same thing will no doubt happen on earth eventually although we have a slightly longer time period due to be closer to the sun and being larger thus having a smaller surface area to volume so we lose less heat to space and the slightly larger force of gravity from the sun also contributes to the dynamo (as does the gravitational pull of the moon). While Mars has two moons, they are tiny compared to ours and so have little effect on Mars Dynamo

Besides why would we want to colonise Mars anyway? Phobos' orbit is slowly deteriorating and will smash into Mars in time. Seems pretty stupid to want to colonise a planet that a 7 mile wide chunk of rock is going to crash into.

You don't need a new magnetic field just a massive weighted magsail at the L1 point.

Luna is on a slowly deteriorating orbit as well . . .

Pretty sure the moon's orbit is getting wider...around 4cm a year, I think.

I know it as 1.5 inches a year. 2.54*1.5 = 3.81. Had to think about that, a bit. 😐

Also, I think that increase is decaying, as well. (meaning, it's slowing it's rate of distancing.)

Busy at work. Can't be arsed to look it up....

The problem in going to mars is the distance and time the astronauts would have to spend in space. The more time in space the more stuff they have to take with them, air, food, and heavy things like water. The more weight the more energy you need to leave the earth. They could of course use the space station as a staging post, ferrying stuff up there.

Then there´s the pychological & physical effects caused by cramped in an unearthlike small area for so long.

In a nut shell we havn´t yet got the technology or know how to get to Mars.

A good idea would be to first build a base on the moon, gradually gaining experience and store stuff there, utilise the water that is present and then eventually launch from there to Mars (less gravity larger payload). Maybe even have a few generations born on the moon, maybe they will genetically evovle to adapt to the enviroment in some way and be more suitable for a Mars excursion.

i dont understand how anyone could think that going to mars would be a good idea

The technology to get to Mars has existed for decades. If you can put something in orbit you can send it where ever you want in the universe, allowing for some patience.

That's not practical. The moon doesn't have any resources to build a spaceship with so you'd have to launch everything from Earth, land it on the moon and then launch again from the moon to Mars.

The fuel? Yes. The chassis and frame? Yeah, there's plenty of good stuff...but not all of it would be available at first.

I am all for mining operations on the moon. With manufacturing and processsing, to boot. Would be easier to do things: less energy required with solar being pretty much the best choice for power, lower gravity, bla bla bla. Even processing.

We have the technology now, just not a cheap enough way to get it too and from to make it practical.

Carbon nano-tube tether and make an elevator?

The moon's orbit around the earth is best described as the Moon and Earth orbiting around eachother, much like if you were to link 2 tennis ball's by a rope and throw them.

We would risk destabalizing the masses of the two objects, such that there are huge climate impacts upon the earth.

Its like space debris, its going to take a lot of us exploiting the resource before we see negative impacts, but just from human history, exploitation of this types normally advances well ahead of our understanding of its impacts.

How would we accomplish destabilizing anything unless that was our direct goal?

What about turning it into a prison colony, like the British did with Australia.

This is a great idea. Obama will make it happen.
