What are the major concerns that NASA facing today regarding the International Space Station (ISS)?

At this point, the major concerns with the ISS are being able to complete it to a point that it will actually be viable as a research facility.  Nearly a third of the planned modules have been canceled and the crew capacity reduced to a point where most of the astronauts time is required to maintain the station leaving little time for the crew to do science.\n\nWith the shift of focus to returning to the moon and going on to Mars, the ISS will likely not be of much use unless the next White House administration redirects NASAs efforts to ISS.

The Earth is a finite resource and will become uninhabitable one day.   Global warming, nuclear accident, hit from a big rock from space - there are plenty of disaster scenarios.\n\nWe need to be prepared.  To that end NASA needs to do so much more research, travel to other planets, set up a base on the moon and mars and, above all work towards spaceflight being like flying today.   Sound far fetched?   When my dad was a boy man couldn't fly and before he died men were standing on the moon.\n\nProfessor Stephen Hawking, he who wrote 'A brief History of Time', recently stated that if mankind did not seek out planetary travel pretty quickly there was a good chance a natural disaster would wipe out all human life!

A non-official website that deals with NASA related information is \n\nhttp://www.nasawatch.com/\n\nYou can learn alot there that you would not get from NASA itself.

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

Deffinitely, we need something from the space program to be PROUD of again.  Since we lost Russian competition, we've squandered our time in space.  I say it's time to do these things, not because they're easy, but because they're hard!

Go to NASA at http://www.nasa.gov/home/index.html?skipIntro=1 They have a ton of information about anything related to space

It's all a waste of money, but it's a better and more inspiring waste of money than the real drains on the government's budget.  Actually, I'm already having second thoughts on that comment.  Read "What Do You Care What Other People Think?" by Richard Feynman.  Before the Challenger disaster, there were indicators everywhere that the shuttle shouldn't be launched.  Thanks in large part to the beauracracy of NASA, seven astronauts lost their lives.  It's a tough issue, but I still think NASA deserves more funding and attention.

well for a candle to burn and have a visible flame we need 2 things convection currents and gravity to support those convection currents. both missing in the space shuttle :))

Lotsa problems : \n\nTime : it would take like 2 years to get there\n\nHuman body : after 1 month in space, the human body has troubles with its bones because gravity doesn't work anymore, imagine after two years\n\nSpace : sun radiations would be very dangerous\n\nHuman himself/herself : who will volunteer for such a task? Imagine been crammed with 6 other folks in a room no bigger than your average kitchen, they'd probably kill each others before reaching Mars...

One of the biggest risks in space is exposure to radiation. Highly-energetic particles - called cosmic rays - are constantly zooming through space. These particles, when they interact with the cells in our body, can cause these cells to mutate and form cancers and tumors. The same thing can be said for the other forms of radiation, most of which come from the sun but some of which comes to us through interplanetary space. These are the ultraviolet and infrared rays given off by the sun, as well as other atomic and nuclear particles which have the same affect as the cosmic rays mentioned before. These radiation also can adversely affect any electronic equipment - satellites, space shuttles, etc. We are protected from a majority of these rays and particles by the Earth's atmosphere; there is no such protection in space.\n\nAnother consideration is the bits of dust that are drifting about out there. These grains (micrometeorites) are extremely tiny but have a velocity which can - sometimes - penetrate a spacesuit or ship. Getting hit with one probably won't be terrible but, a few hundred can severely damage a spacesuit, shuttle or whatever equipment might be lying in their path.

The suits protect astronauts from UV radiation (their visors and suits), but they do NOT protect them from the radiation you are refering to.\n\nAstronauts are exposed to radiation.  NASA does everything it can to minimize that exposure.  They limit the time spent outside the spacecraft.  They carefully monitor the Sun for radiation bursts.  They also track and measure the radiation trapped in the radiation belts (which is the biggest threat to the astronauts), and they time space walks to minimize that exposure.\n\nA space walk is a big risk for an astronaut.  Besides radiation, meteoroids are a threat as well.  It is quite a feat of bravery to make a space walk.

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.
