NO , I like it here on Earth. I don't even like the loss  of environmental control on airplanes. I'm not afraid to fly in them, I just don't like to although I always enjoy the veiw when there is one. The food is better on Earth too. If I was fgoing into space though, I would bring 12 cute female massage therapists. If they were going, I change my mind. I'd go too.

One problem, insurmountable so far, is how to protect astronauts from cosmic radiation on long journeys. People on earth are protected from cosmic rays by the atmosphere, but in space, prohibitively heavy protection would be needed even on so short a journey as to Mars. The problem remains unsolved.

I think that a return to space is inevitable, and will reap enormous benefits in our understanding of ecology, medicine, electronics, propulsion and power generation, food production, and a host of other areas that we can only guess at from this side of the process. \nMars is a good goal, simply because, as JFK said, "it is hard." Landing on, and staying on, Mars, or the moon, is a tremendous undertaking, and one well worthwhile.\nThe problem, as I see it, is that while we are wasting so much of our energy combatting phantoms, we may find it difficult to coordinate the necessary effort to succeed in such an endeavor.\nSo until "terror" stops being the driving force in American politics, I think any serious striving for "progress" will be put on the back burner.\nAnd that is a terrifying though, isn't it?

Many experiments that have help us advance in medicine are conducted in space. Our planet can be in danger of asteroids plunging into us, and can result in life on earth being destroyed, and by expolring space, we can find out and save us, so yes, it is worth it. And it's fun!

Learn to use the caps less annoyingly.\n\nOn the space ships, they use vacuums. They suck up the waste. Then they either carry it with them until they land or dump it into space.\n\nWhen I said dump it in space I was mainly referring to moon missions.

The astronaut actually has to pass his own gas to stay warm in space :).. \nok seriously To work in the open cargo bay of the space shuttle or in space, astronauts wear the shuttle extravehicular mobility unit (EMU) spacesuit and they are kept warm by their own bodies heat because of the well insulation and design of the EMU

Well, you can find many web sites on spacecraft design, try that.  But, I can respond to one point.  A good spaceship will be a structure designed to be assembled in high orbit, and will not enter any atmosphere.  All of the structures necessary for high gravity atmospheric travel are useless dead mass when it come to space travel.  We are not quite to this point, but getting closer.  Check out the current Mission to Mars plans at the NASA website.  Three different launch vehicles.  That is the first step, how to get things into space efficiently.  If we get better at that, we will see more ambitious construction projects, like a permanent moon base, or a high orbit space station.

It is very technically feasible for humans to be able to live on another world. If we went ahead today we could have a pretty selfsustaining base on the moon in 20-30 years. \n\nMany aspects needs to be resolved and they are more biological than technical. Can we grow all the food we need on a body with a different gravitational field than Earths? Everything on Earth has evolved constantly exposed to earths gravity. We can grow simple plants on the ISS but the humans aboard will suffer dangerous health issues when exposed to longterm microgravity. What would these effects be on the moon? Less, probably, but will they still be there? And how will more complex plants fare on the moon? What about food that isn´t from plants at all? Can chickens and fish be produced on the moon? Will it be necessary for humans in space to be vegetarians since a Big Mac will be worth its weight in gold?\n\nHow long for a colony on another planet to be completely independent of Earth? I would say centuries if ever. Because how many nations are completely self reliant here on earth? Every nation imports and exports something. We are dependent of trade. Will there be such a thing between planets?\nEconomy is the most important factor in manned space exploration. If it hadn´t been for the Vietnam war we would have built the first permanently manned bases on the moon in the eighties. The war ended up costing 6 times as much as the Apollo programme. No wonder it got cancelled...

I would go if I could afford it! Hopefully this commercilization of space will have the same effect as when anything becomes commercial - Things cost less and less and advancement come faster and faster. I'm waiting for a week long vacation at a space hotel.

They carry their own.\nEither in the form of liquid oxygen, or they use a fuel that  will liberate oxygen as part of the combustion reaction, like hydrogen peroxide.\n\nNote that these are very inefficient, because you have to haul large masses of oxidizers up out of the gravity well...  This is going to put an effective stop to long-haul space travel until a better form of propulsion is well established.\n\n(For extra points...)\nIon drives, mass reaction drives and things like hydrogen "ramjets" are being worked on as alternatives -  and, my favourite concept, the solar sail, is in the wings...  :-)\nI've sailed the oceans, I would really love to sail space, but I doubt I'll live that long.

A space suite has several functions like it has to protect you from cosmic radiations, keep your body pressurized in near vacuum situations, protect you from micro metroites, provide you oxygen flow to breathe, carry items/attachments that you need including oxygen, and provide you enough flexibility to move around & carry out your work. \n\nWith these objective you need to select proper set of fibers, pressurization startegy, electronics, attachements, etc. and put together a space suite!\n\nBest of luck!!

...according to "official" blueprints of the ship, there's a bathroom right off of the main bridge.\n\nActually, I take that back...according to Wiki:\n\nAs a running gag, bathrooms are never shown on Enterprise schematics. The gag was started when toilets were accidentally omitted from the design of the original Enterprise. This joke is referenced in Star Trek: First Contact when Zefram Cochrane asks Geordi La Forge "...don't you people from the 24th century ever pee?" In a special, aired before the final episode, Jonathan Frakes actually answered the question of where one could actually find a bathroom on a diagram of the ship, and pointed to a diagram of the Enterprise seen in Engineering, indicating where it was. For the record, the only confirmed appearance of a toilet aboard the Enterprise was in Star Trek V: The Final Frontier.

They use toilets that have suction, like a vaccuum does. The guys that go in space have to pee in a hose that has suction and that gets kind of wierd...a guy and a hose.....

u know wot!space doesnt even have enough air to carry sound waves !so lifeforms we know have no damn way sustaining their life in space!\n\nbut , there is oxygen in space, however, the majority of it has already \nbeen captured gravitationally by stars, planets, or other celestial bodies.  \nSo space is almost a perfect vacuum, but gas and dust particles do float \naround out there.  These particles are referred to as the interstellar \nmedium by astronomers.  \n\nAccording to Thomas Arny's "Explorations: An Introduction to Astronomy," if \nwe were to compare the amount of gas in interstellar space to the air we \nbreathe, it would be like "one marble in a box 5 miles on a side compared \nto the same box filled completely with marbles."  So needless to say, there \nisn't very much oxygen in outer space, but there is some.  And the reason \nthere isn't more is simply that the gravity of all the other various \ncelestial objects out there, including galaxies, has captured most of the \ngas and dust.\n\n\nbut universe is so large , who knows there could be other places where air could be found even then i seriously doubt the presence of enough oxygen\n\n\nAstronomers have detected the first presence of oxygen and carbon in the atmosphere of an extrasolar planet, a world already known to be venting massive amounts of gas into space. \n\nThe find is evidence of an atmospheric "blow off" in action, where energetic hydrogen gas drags heavier elements along for a supersonic ride into space.\n\n\n\nDespite the oxygen, the faraway planet is not one that would support life.\n\n\nThe Jupiter-like planet is officially called HD 209458b, tcalled  Osiris after an Egyptian god who was dismembered by his brother Seth. It orbits a Sun-like star 150 light-years from Earth. \n\nAstronomers already knew the planet was rapidly losing its atmosphere after they  found it spewing out enough hydrogen gas to create an envelope that extended and trailed the extrasolar world. \n\nThe planet was thought to be losing at least 10,000 tons of material each second, but researchers weren't sure the process was powerful enough to dredge up heavier elements.\n\nCarbon and oxygen atoms are 10 times heavier than those of hydrogen, and therefore would normally lie low in a planet's atmosphere. So a force stronger than gravity is driving them up along with the hydrogen gas into the extended envelope around this planet\n\n\nThe venting process has been attributed to a pair of reasons, namely the intense gravitational forces between the planet and its parent star, as well as the super-hot temperature of the planet's atmosphere. HD 209458b circles its stellar parent every 3.5 days from a distance of just 4.4 million miles (7 million kilometers), which is closer than Mercury's orbit around the Sun.\n\nThe tight orbit causes intense gravitational tiding that stretches the planet's atmosphere into an oval shape, not unlike a rugby ball, which can allow gas to escape. The upper atmosphere itself is baked up to 18,000 degrees Fahrenheit (10,000 degrees Celsius), which forces hydrogen atoms to expand outward at supersonic speeds. \n\nThe hydrogen wind erupts away from the planet like a geyser and is powerful enough to sweep up carbon and oxygen with it. \n\nThe planet may eventually shed its entire atmosphere, leaving behind only a solid core remnant of its once massive self.  \nThe process is similar to one that may have eventually produced the atmospheres around more local planets, such as Venus and Earth\n\n\n\nHD 209458b orbits a star in the constellation Pegasus, which can be seen with binoculars from the ground. The planet was first detected in 1999 using the wobble method of planet hunting. A separate team of astronomers previously detected sodium in the planet's atmosphere as well\n\nso maybe u r not so silly after all ,as this is a question to be answered satisfactorily answered!!

A while ago when I was in school yet, our Sociology teacher posed a question( as many do) about a lifeboat with survivors on it; many on the boat were near death. One person was given the task of deciding how to ration water and food for all the survivors. This individual divided the rations amongst all of the survivors equally, even those who would perish anyway(human nature). However, by the end of this social experiment, I do recall... we all perished. There was not enough to ration out to all, so we ended up starved, dehydrated and then fish food.

Who's this "we"? All 6.6 billion of us? We'd never be able to put together all the needed resources, starting with 7 million 1000-passenger space liners and the necessary 100 trillion tons or so of propellant.\nOK, so we scale down a bit. First, 99.9999% of us volunteer to stay here and die; please step forward. (BTW, this might actually be doable, sending 7000 people to build sealed dwellings and colonize mars, but it would still be a huger project than we have ever undertaken.) \n.... OK, nobody stepped forward, so we try plan b; select a few of our fittest to go; the scientists, artists, guys with guns, hairdressers, telephone sanitizers, etc. plus the, um, necessary biological counterparts to ensure continuation of the species, who must for that reason be chosen for their, ah, sexual attractiveness...\nAnyone remember Doctor Strangelove?
