When in space,astronauts can not tell what time it is so I want to know how that affects their sleep pattern.Do they get enough sleep?Do they over sleep?

same as those of us who were on submarines... you sleep when you can.  thos astronauts are so busy up there, that when they get a chance to sleep, i'm sure they take it, no matter what time it's supposed to be.

There will be times in your life when you will need 12 hours and it's no big thing.  Your body tells you when you need sleep, and if it's at all possible (like not at work or driving, etc.) then listen to your body.  When you sleep your body rebuilds itself.  Just don't over-do it night after night with that much sleep.  Normal needed is about 8 hours a night.  But you can play catch-up sometimes.

sleep DOES effect your daily life. you need at least 7-8 hours of sleep a night to be fully rested. a bad nights sleep, or no sleep, can put off your whole day. go long enough without sleep, and your brain will shut down and sleep, whenever it wants to.\n\ni go to sleep about 11pm and get up anywhere between 7am and 9am.

Everyones sleep pattern is different: People who are 'Larks' are up before the sun, yet half asleep around 9pm. Those who are 'Owls' are the life and soul of the party well into the early hours, but are like the living dead if forced to get out of bed before 11am or later. Some people need a lot of sleep, while others can manage on 3 or 4 hours. There really is no good or bad concerning sleep. Provided no drugs are used, and you feel all right, your body and mind will let you know when to sleep and when to be awake.

we dont see moonlight, the astronauts didnt see earthlight. what we and the astronauts saw was actually sunlight reflecting off of each (moon and earth). the moon gives off no light and all the lights on the earth would not make a very bright light if you were staring at the planet from the moon's surface.

u might have heard abt latitudes. Sun light constantly falls on earth. as earth moves different past of earth receives light and this is what we term as day and night. Latitudes help in determining times and it takes 15mins for sun to pass from one latitide to another. In other words we have time zones ever heard of green whtch time zone. This way, time is calculated with respect to sunrise and sunset. \n\nThus its all depending on how sunlight reaches in ur region..!

The main problem with space biology is how little we know about the behavior of earth organisms in space. The biggest problem is how little we know.\n\nWe know that gravity, air pressure, atmospheric composition and solar radiation effect organisms. \n \nWe know that in a weightless environment human muscles atrophy and bones lose calcium and weaken.\n\nWe do have enough knowledge of biology to build environments that will keep humans and plants alive for years in space with the addition of energy, air and water from outside. \n\nWe don't yet know what are the critical earth factors that must be duplicated, with technology, to establish thriving space colony ecosystems. Or which organisms will survive better in weightless environments. How will a bee behave in zero gravity?

Does night actually move faster than day?\n\nThat doesn't really make sense, because while it may be night in one place, it will be day on the other side of the world. So they must both be moving at the same pace to be happening simultaneously, right?\nSorry I can't be more help, but I believe they both move at the same pace.

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

The theory is strong.  It should work that, if an athlete were to train under a progressively increasing gravitational pull, he or she would perform proprtionately better under in a lower-gravity environment.\n\nThe converse is true, as proven by astronauts that return to earth after long stints in micro-gravity.  They have been quoted as saying that a standard wrist watch becomes a bowling ball on after as little as 30 days in orbit.

no, i haven't been to space or around the world. then again, not many people have.\n\nit would be ok and all but just thinking about being out there not knowing "exactly" where you're headed. i'll pass. what if you run out of gas and your ship is stuck out there? what if you lose contact with humans on earth, how will you let them know that you need help??? but then again on the other hand, you are in space seeing everything with your own eyes. nah, i'll stick to seeing space through internet and through my dreams..i'm a lot safer in my bed dreaming...

Supposedly it's true, there were visitors around the ships, I think that they (Astronauts) refered to them as "Space bugs", they were (and are) seen floating around the ship on several occassions, NASA is well aware of them, they show up on just about every launch, supposedly harmless, but still a life form of some sort. One school of thought is that the reason the moon shots were cancelled was because, NASA had found evidence that now, or at one time the moon was being used as an observation post for another life form that was studying Human behavior on Earth.... Perhaps they got sick, after seeing how we treat each other, and left ! Pretty interesting stuff, Huh ?

In my experience, the nightime creates a sort of 'bubble' around your consciousness - in the same way that sitting in a room while it storms outside does.  It isolates and envelopes you, and removes stimulation.  So, logically, you're left to ruminate on what's occupying your conscious mind at the time. Also, life, ostensibly anyway, appears to 'slow down' at night.  It is the designated time for relaxation, sleep and general recuperation (traditionally, anyway!). So with less external influences to 'dilute' or 'put in perspective' your thought stream, so any issues will seem like the only things happening to you and your entire reality.

I work at NASA and help train the astronaunts.  It's not like the movies (AKA Space Cowboys).\n\nMost astronaunts are skilled professionals with multiple degrees.  They are constantly being trained for a shuttle launch.  About 4 weeks before launch, their training increases from 30-40 per/week to up to 60 depending on EVA's and stuff.

I don't know if your question is serious or not, but if it is...from reading literature about UFOs and alien abductions, it seems like they were abducted by aliens. Only hypnosis will help them remember what happend during the two and half hours they don't remember.

There are a lot of considerations, like the amount of 'deep sleep' or REM (rapid eye movement) time.  It turns out that things like blood pressure and melatonin (hormone related to sleep) follow the diuranal cycle.  Yes, the sleep should ideally be at night.  That is how the human animal evolved on the planet earth.

Look at how many sattelites we put up... there is something wrong with your reasoning, you're ignoring a lot of the facts.  How is it more difficult now?  A civilian recently built and flew his own spacecraft into space 3 times successfully.  Hundreds of satellites are orbiting the earth as we speak.  How does it seem space travel is more difficult?  We have several astronauts in a spacestation right now... Civilians have purchased tickets into space, the people on the space station have been relieve, replaced, etc multiple times... As far as the moon goes, there really isn't/wasn't any reason to go back, not a whole lot there if ya know what I mean ;)  They're working on mars projects continuously... just because a few landers and orbiters crash doesn't mean things are more difficult.  If you do some research you will find literally hundreds of crashes, mislaunches, explosions, and other quality errors; the old times make the number and degree of current mistakes seem almost trivial.  Science and technology have proven themselves time and time again when it comes to space, and it keeps getting better.
