Humans belong on the earth, or using a more liberal interpretation, within the earth's biosphere, so as not to exclude travel within the lower reaches of the atmosphere or the oceans.
Regarding the ISS, the three astronauts should be evacuated at the earliest possible time and the project abandoned. A possible followup project would be use of the ISS as a laser weapon target, thereby providing a means whereby earth-based mass spectrometers can be precisely calibrated as aluminum, titanium and other alloys are vaporized in the vacuum of space.
To everyone who is against US backed manned space flight:
Here is a problem maybe you’re not considering, the Chi-coms believe very much in manned space flight. They are about to launch their first manned rocket "Long March" into orbit. They have further plans to go to the moon. Our lives here on Earth would be immeasurably altered if this is attained. We sit here below the moon under a very large gravity well. If we cede the moon to them we loose any protection from our military dominance of the world. They can sit back and use mass drivers and hurl rocks at us and there wouldn't be a
d@mn thing we could do about it, no missile defense system would be able to stop them.
With the moon as a safe harbor it would not matter to them how many nukes we have. There production base would be hugely improved: Fuel is available i.e. water and food production would be greatly increased with underground farms- simply grow the food then launch it back relatively free down the gravity well to earth which also gives them a great excuse to have that mass driver.
A base on the moon endangers all satellites and anything else we have in orbit and on the ground.
This may sound fantastic and unbelievable, but it can happen, the technology is there albeit very risky, but I doubt the Chi-coms give a damn about the risks.
