I agree with alpossmar82 that thinking before hand is most useful to science.

Mars atmosphere composition ( prediction ?) here;-

...and photo showing erosion that looks like water at first but look at the craters and guess what water would do there on Earth

It goes to show other planets are a lot different to Earth and things could be a lot different here if the environment changed. Perhaps that is why NASA was not really digging in and coming up with mind expanding new ideas from the Martian environment.

Metaverseguy: Anyone watching the reboot of Cosmos? I missed the first episode but saw the one that aired this last Sunday. They spoke for like 30 minutes about Titan, a moon around Saturn. Completely inhabitable but has actual water unlike 90% of planets we've seen, just frozen in the super cold methane oceans.

You can live on any planet if you have a spacesuit and the planet is n't too big.

Metaverseguy: Idk Lipton. If you've got a 4 hour oxygen tank on Neptune you should be good, right? Just teleport back to Earth through a worm hole when only an hour remains. But if you're hungry bring a snickers bar because there is 0 plants growing on the planets and moons that we've seen.

LiptonCambell: Haha I tried to act all smart by pointing out that Neptunes Gravity would crush you....but it ends up it's not that bad- 110% of our gravity- so 100 pounds here is 110 pounds there...

Then I thought- heat! But alas, I forgot, spacesuits can survive the temperatures in space(go figure), which would always be colder....Humbug...you chose a safe planet to visit

I am sure if you can build a spacecraft to get you there you are smart enough to build a camper suitable for the type of planet.

The point is the other planets in the solar system are not going to be turned in to Earth like environments without enclosures to keep the old environment out.

Metaverseguy: The only way space agencies have been able to even get close-up photos of Neptune is when the planets were aligned close enough so that the satellite could use the gravity of the planets to fling itself into the orbit of other planets. These being men who study their entire lives and continually prove they are the best engineer and scientists available for the job. Space ship would probably be too heavy if you managed to survive long enough for the ride there somehow. Plus Neptune is a gas giant, meaning it doesn't even have a surface to land on.

I would say Mars is commutable from Earth. But there seems to be less reasons to go there.

Metaverseguy: I will have to take a look at that Duncan. Yes, leaving Earth for Mars would be like leaving the Tolkien world to live in the wasteland of John Wayne movie, without even the silly cowboy act. But if someone got there it would mean space technology advanced a lot. Maybe enough to get us to other solar systems and create anthropogenic environmental problems.

an·thro·po·gen·ic [an-thruh-puh-jen-ik] = caused or produced by humans: anthropogenic air pollution.

As much as I don't like the Tolkien world I don't think Mars has a lot to offer.

Used as a comparison to Earth it might encourage better Earthology and care of the planet but apart from industrial use I don't see there is much to gain from going to Mars.

You are right it is like a wasteland, but I am not a John Wayne fan.

I think Mars could have a use as a training base for people at work on or near other planets but life on a Space station would be more fun and as a Mars base would have to be as all encasing as a Space station why not start there first? Mars has too many buts.

If Earth skys got too crowded in the future, way in the future now, Mars could be used to orbit another Spacestation around.

Metaverseguy: Of course looking at the barren Mars and the plentiful Earth and everyone's eagerness to go there it's a good reminder that at one time the Earth was just steaming lava and a weird atmosphere. That the process of unicellular life to multicellular life took millions of years. If somehow the core started again and volcanic eruptions started happening, fueling an atmosphere then who knows how long it would even take for liquid water to appear, if at all.

Mars is about one half the size of Earth. Since Earth is about 70% water then wouldn't Mars be something similar to the same ratio? So the only habitable land would be one giant continent like the entire Americas only or Europe + Africa only or Asia only.

Yes, the comparison between the plentiful Earth and the Martian waste land is a shock.

There seems to be only a little water on Mars compared to Earth, but still quite a bit and it reacts with the major chemicals in the soil to form Sulphuric acid.

Perhaps that is why NASA tried to hide the Polar caps. Because the freezing and unfreezing action of the weather means that Sulphuric acid is formed, and in strong concentrations.

Water and Sulphuric acid separate when freezing causing a weather cycle.

Mars is very acidic.

When NASA showed its Martian lander it was pointed out that if it was made with the materials they said they would it would not work. And in the end they brought commercial paint that resists acid and painted their craft.

It was a salient moment in Bill Clintons Presidency when the newspapers, who had made an issue out of the Martian program, realised that he could not understand.

Metaverseguy: Well, I think Bill Clinton had other things on his mind during his presidency, such as hundreds of scandals and ridiculous political affairs in countries no one could locate on a map.

Anyways, a lot of the rovers and satellites were sent off in the 90s so the funding was still there in the programs. No returns to the moon which would have been pointless anyways unless they were trying to build a base or station there.

Buzz Aldron said that we need to make a station on the moon as a waypoint to Mars. That would save the astro-explorers only 4 days in a six month journey. Not very impressive.

It seems Mars shots were more likely under a Democrat administration but the science is very poor quality.

Characters such as John Travolta, who have convictions for trying to cause the govt to spend tax payers money, were involved and interested in the engineering.

If you were near the US space program things in space you would not like it at all and any alien meeting them might not understand what they were going.

Metaverseguy: The space program guys who go in front of Congress (at least here in the US) to beg for money have it all wrong. You want to go to Mars you don't try and convince them we need to find water. Water is penniless, worthless material that no one cares about. Fake some photos or better yet attach the rover with drilling equipment that can drill a mile deep. You want a "space exploration" of Mars tell them there's precious resources like oil or diamonds there. They find liquid gold then they'd sent hundreds of space ships over there like Avatar.

LiptonCambell: Of course there would be diamonds there...it's just easier to find diamonds here....

Too bad there isn't oil there....unless we can prove it once held life

Not being believed and not telling the truth, and in fact standing in the way, obscuring and trying to restrict people from seeing the polar caps, go together.

I am no more convinced of their spacecraft then of their science when they have mislead us about basic ideas.

Mars is a smaller planet so taking material in to space from there would be cheaper then from Earth. Materials would be basic minerals and ores if any could be found.

Spaceweather has published a photo of Mars ahead of the Opposition of Mars.

"OPPOSITION OF MARS: Earth and Mars are converging for a close encounter in April. It's only March, but the view through backyard telescopes is already superb. Michael A. Phillips of Swift Creek, NC, took this picture using a 14-inch telescope on March 27" Spaceweather

It is clearly winter on Mars.
