Q: How much did it cost to send a tiny robotic drone to mars?
Q: How much more would it cost to send multiple humans and ALL the equipment to support for a minimal amount of time...include state-of-the-art renewal systems?
Q: Why is anyone taking this seriously?

The gravity problem is probably solved by rotating stuff on the ship.
It is much easier to build or send and use a similar system on the surface of mars than in space if there are any bone issues there.

Maybe they will have to spend some time in a rotating device on mars as well, for example during sleep. I think it is that "easy" Smiley

Acceleration and gravity should have the same effect according to my physics book. I don't know why I feel like vomiting in a spinning carousell though... Smiley

Because your inner ear tells you that you are stationary (constant acceleration, just like gravity) while you see that the world is spinning. This conflicting input can cause you to get sick.

So, as long as you don't have windows in your spinning vehicle, it'll be just fine.

Stationary = constant speed, not accelearation. You definetely wouldn't feel stationary if you jump from the 10th floor... You'll feel the acceleration (gravity changing your velocity) all the way down, and then when you hit the floor (constant Velocity = 0) you'll be dead stationary...

Actually as soon as you stand up, it isn't, not for any length of time.  You have less gravity at your head than you do at your feet, which is going to make your equilibrium scream "something is WRONG!!!" the whole time, especially when you start walking around.

That part might be fixable with experience (sailors don't get seasick after all) and possibly some surgical tweaks to the inner ear.  You'd have to spin fast as hell to get even a moderate size ship to 0.3G, and that makes the differential worse.

That doesn't sound implausible at all.  A brick press isn't exactly ultra high tech, just repurpose a hydraulic pump or two from the ship.  'course making bricks from what amounts to sand and not clay dirt might be a bit trickier.

We have the same problem on Earth, so I guess whether it is relevant, depends on the diameter of your rotating vehicle Smiley

I guess we can make those vehicles fold out in space, just like with solar panels, so that we don't have to launch objects with horrible aerodynamics.

It occurs to me that bricks would become more plausible if you added some organic material from the outside to substitute for the clay.  Perhaps "contributed" by the crew, lending some verisimilitude to another phrase involving bricks...

You can't just take material out of the cycle that produces and transforms food. Also, bringing the materials to create bricks to Mars would be rather inefficient, as there are lighter and stronger materials available to build walls.

Wowee you're popular. I'm only looking at 44,000... then again my name is not at all common, if your name is like "Bill Miller" then you'll get a lot of hits that aren't relevant to you specifically. This Suzanne chick has an extremely unusual name.

where it is very possible, that there is actually liquid water there

I mean, revitalizing mars is fine

but there MIGHT be life in our solar system

The radiation level at the surface of Europa is equivalent to a dose of about 5400mSv (540 rem) per day, an amount of radiation that would cause illness or death in human beings.

Life maybe, but doesn't seem feasible to move there. Maybe interesting:

I can't help thinking of "Capricorn One" and then there was the UK reality TV show "Space Cadets".
The latter was pretty funny (they carefully selected non-science people) and you can find some of it on youtube.

At the moment, I can't see the point of a manned mission to mars.  The environment is pretty hostile.  Robots are better suited to go there.  Gravity is about a third of earths, leading to low atmospheric pressure, which in turn makes liquid water unlikely, as it would tend to vapourise.  There is ice at the poles though.  Maybe one could design some sort of nitrogen-fixing bacteria that could live over the temperature range, except that the atmosphere has less than 3% nitrogen; it's mostly carbon dioxide.  After 5 minutes of googling (so now an expert), I'm not convinced we are going anytime soon, although EASA and NASA think they are going there post 2030ish.

A trip to the Mars chocolate factory would be much easier, quicker and there's chocolate.  I visited Rowntrees (Nestle) once years ago.

That's CO2 ice. Also known as dry-ice. It's not usable for your settlement.

Even then the 'one way trip' part of it would make me hestitant.

Water is known to exist on mars in abundance, there being quite a bit of ice just under the surface.  Water is probably the least of the problems.

Yeah I heard about his one: Apparently there are some particles that go through they eyes, even when closed and causes people to see stuff. In a long run it might screw up the eyes somehow.
Not sure about the "male" criteria.
Its just another form of dangerous radiation in space, what else is new Tongue
