what are the effects to the human who were sent to explore the aerospace?

in space there are negative effects such as loss of bone mass and gradual weakness due to the absence of gravity.

Here's a selection of first person in space from various nations around the world.\n\nYuri Gagarin - Soviet Union\nAlan Shepard - United States\nVladimír Remek - Czechoslovakia\nBertalan Farkas - Hungary\nJean-Loup Chrétien- France\nRakesh Sharma - India\nSalman al-Saud - Saudia Arabia\nRodolfo Neri Vela - Mexico\nToyohiro Akiyama - Japan\nHelen Sharman - United Kingdom\nIlan Ramon - Israel\nYáng Lìwěi - China

Yes - we learnt that there was no cheese in the moon or that there were no green men in mars.\n\nJokes apart - improvements in space travel - hs helped in improving sea going vehicles (submarines etc) also treatment of paraliysed people, also treatment of muscle atrophied etc...\n\nalso the satelite age heraled the ability for us all to better predict weather changes and also determine where the next oil deposit could well be...etc\n\nso you need to look at it all in the context of the benefits of space travel...so yes its important...\n\nand the money spent is well spent

From your own hard work and effort. Noone here will do anyone's homework for them.\n\nMy suggestion - if it is a project on astronomy, quote a famous astronomer, like Percivel Lowell. If it is a project on the large nature of the universe, find a catchy quote by Einstein or Stephen Hawking. And if the project concerns the space program, you'll find wise words from any astronaut who has been up there and made awestruck comments about what it is like.

I will do it to satisfy my curiosity. A free trip in the space to discover other inhabited planets and galaxies is a dream come true. It is an occassion not to miss out but i would not go for ever because there can't be no better place than our home. I will return back to earth after the trip to my home sweet home.

NASA experiment a lot on this issue, maybe by login onto their site you'll find the info you're lookig for, luck..☺

Depends on the amount of pollution, The cost of things, house rents, And the friendliness of the people(who knows whether they'll be blood sucking parasites of whether or the next brady bunch), The rate of oxygen masks and tanks... etc.And of course, depends on the space shuttle rates for travelling from mars to earth.

YES. The atmosphere is so thin you can't breathe. When the first astronaut, Alan Shepard, rode Freedom 7 in suborbital flight we sure thought we were going into space. All the hazards of deep space were experienced on that flight.

Absolutely! I would hope since the previous trip ended in disaster, NASA would be extra-cautious. It would be a once-in-a-lifetime opportunity that I couldn't pass up.

The astronauts would be in zero-G for almost the entire trip causing the negative effects of weighlessness on their bodies.\n\nThe accereration of the spacecraft would indeed negate the problems with Zero-G by temporarily creating artifical gravity.  The problem lies in the fact that with the limited amount of fuel on the spacecraft, acceleration would only occur while the the engine was on. (a very short time with a chemical rocket)   \n\nOne solution would be to use a a drive that will burn during the entire trip.  One such drive is an ion drive (used on the recent Deep-Space One spacecraft to visit a local asteriod).  This drive would acclerate for most of the trip there creating a small amount of artifical gravity.

With the current advances in transportation technology, it will be possible it is just a matter of time.  The main problem that space exploration has to deal with is radiation surges caused by solar flares.  They have to develop a proper shielding and detection system that is light enough to launch into outer space.  That is one of the reasons why it is debated whether or not man has even walked on the moon because of the immense amount of radiation that the ship would have been forced to endure would it have traveled that distance.  There are a number of other proofs provided for both sides taht I will not get into.  I think that it is possible and that man will accomplish it if the Lord tarries his coming.

I was in B. 37 at Johnson Space Center in the Medical Science Division.  About 50 of us who worked in the building were watching the launch on TV as we did every launch.  I had built an experiment box for one of the crewmembers to use. It was a space motion sickness experiment.  The person seated in front of me said "oh no, that's not right" prior to the "explosion".  About 5 seconds later, it broke up.  It wasn't really an explosion by strict definition.  The pressurized crew cabin seperated and it fell into the ocean after reaching about 57000 feet.  It broke up most likely on impact.  The person sitting in front of me noticed the anomalous plume and knew something was terribly wrong.  One of the crewmembers family lives behind me, 2 houses over.  \n\nI am answering this question in a non-official capacity of course, but I have to say it.

Like the others who have responded, Buzz Aldrin was the second man to walk on the moon. He was so effected by the experience and also having completed such a long sought after goal that he had to have some emotional guidance from a counselor after his return. I'm not saying that he had a breakdown he just needed help to get his mind all the way around what had happened to him.
