Well lets see.. first there is the pressure of the ocean floor. If we can develop a metal that can withstand the pressure of that..then chances are it will withstand the vacuum of space..and might even stand up to those micrometeors.
Next there is the fact that if something does go wrong and the sphere cracks that the ocean could come crashing in..much like the oxygen/atmosphere escaping if the dome gets punctured. If we can find a way to overcome that .. then we are a step closer to figuring out how to overcome the loss of atmosphere in the domes.
If we can make a self sustaining biodome under the water, then chances are it will go a long way toward making a self sustaining biodome in space. Nope, no benefit there.
Simply put..the ocean is a much more friendly environment then space, yet we can not colonize the bottom of it. When we can, then we will be a little better prepared to colonize the harsher environments in space.
When you are first learning to walk, you don't challenge the fastest man in the world to a race. First you learn how to crawl, then walk, then run.
Anyhow, I'm done. We can agree to disagree. *shrugs*

Hardly, colonizing a different planet is significantly more complex than colonizing the ocean floor.

I don't think ocean domes are necessarily the best means of learning how to colonize a planet unless we wanted to colonize a planet that had a rather large atmospheric pressure. Basically 10 meters of ocean depth = 1 atmospheric pressure.
I think building and maintaining a space station is a huge step in the learning experience. One we have already done to some extent. The proposed "parked" space station would be a huge step not only for increased exploration but as a way point for the supplies that will be necessary and we'll learn many things that would apply to colonization as well.
I think it would be a while before a colony would be "self sustaining" and the best way to learn how to make a colony self sustaining is to found a small base on Mars and build from there. There are a lot of questions but the only way to answer the questions is the get out there and find the answers. Lots of challenges, but a lot of potential rewards as well.

Well, there is one type of "Habitat" in space. No breathable ait, deadly cosmic radiation and micro meteorites.
You have none of these in the ocean.
The point was "If we colonize the habitats on earth, we can colonize e.g, Mars, easier. Problem is. Colonizing an ocean is completely different from space or mars.
Firstly, deep water has ridiculous amount of pressure.
Then you can use a nuclear reactor to break down water for oxygen and then you have endless water supplies and then you can actually plant something on our earth.
Mars ari pressure is 0.01 atmospheric pressures (I could be wrong),
it has selfsteilizing soil (Like volcanic soil), completely useless for planting and you have NO water.
Xerox is right. You dont need to eat an apple to find out how to eat a water melon. They are completely different matters.

Scientists say the Mars Curiosity rover has made a finding "for the history books." They won't say what it is until a meeting in the first week of December.
If microbial life is confirmed to be on Mars do you think exploration of Mars should be stepped up?

John Grotzinger, lead mission investigator for the Curiosity rover, set the rumors in motion during an interview with NPR last week, saying, "We're getting data from SAM … this data is gonna be one for the history books. It's looking really good."
Whatever history-making news there is to report, Curiosity scientists are expected to cough up the goods at this year's American Geophysical Union (AGU) meeting in San Francisco, to be held from Dec. 3 to Dec. 7.
......
"I think the minimum finding that could get Grotzinger to describe it as 'historic' is complex organic compounds," said Gilbert Levin, an adjunct professor at Arizona State University in Tempe.
Levin was a life-detection experimenter on NASA's Viking mission to Mars in 1976. Levin and co-experimenter Patricia Ann Straat led the Viking Labeled Release (LR) investigation, which returned data from Mars indicating the presence of microbial life, the team asserts.
"I have already pointed out that the Viking PR [The Viking biology package also consisted of the Pyrolytic Release experiment (PR)] showed that simple organics are continually being formed on Mars, so they would be no big deal for Curiosity," Levin told SPACE.com. "I doubt SAM could have detected proof of living microorganisms. But, slowly, ineluctably, NASA is being dragged into the mire of life on Mars, and will ultimately, maybe soon, have to reverse its opinion on the results of the Viking LR."
If Curiosity has found organics, Levin said, it will thereby confirm that the GCMSwas not sensitive enough to rule out the positive findings of the Viking LR.
"The failure of the Viking GCMS is the only remaining obstacle to acceptance of the Mars LR having detected existing microbial life. That obstacle would be removed by the Curiosity finding of organics. Whether that will turn the consensus in favor of life, I do not know, but any rationale against it would be difficult to maintain," Levin concluded.

I don't believe. Water is in space or better example for space bacteria just common thing. Isn't interest, who cares? I interest a fossil, what? Plants, animals and skeletons. It's better discussion as make bacterial weapons from Russia! Animals, example of fish give world's best answer to religion as plants, when water gave plants, but who gave animals?
