Does anyone know when nasa will be planning manned expeditions to other planets, such as mars, or other moons.
I heard somewhere that in like 2011 when we have nuclear powered shuttles, we may go to one of the moons on jupiter.
So does anyone know any information about when we plan to explore other planets with manned expeditions
Any input would be nice

Interplanetary exploration poses other problems besides getting from point A to point B. For instance, Jupiter’s magnetic field is so powerful that it acts like a giant particle accelerator and creates belts of radiation 400 times more powerful than needed to kill a human. These radiation belts cover most of Jupiter’s moons making exploration of them by humans very difficult and expensive, never mind the cost of getting there in the first place.
Robotic and AI technology is likely to advance at an incredible rate in the 21st century. My prediction is that the majority of interplanetary exploration missions will continue to be done by machines with humans remaining safely at home. I don’t think the future will resemble anything like that depicted in books, movies or TV.

Where did you hear this? I wouldn't expect anything to come from NASA. By the time 2011 comes around, the United States will have almost completely abandoned it's manned space-flight program -- as if it had much of one to begin with. Here's an article I found on Spacedaily.com discussing this topic:
The End Of US Manned Spaceflight Looms Ever Closer (http://www.alternight.com/phpBB2/viewtopic.php?t=482)
Even if NASA did begin launching manned missions, it wouldn't last for long. When the U.S. tap-dances across the 50 percent "public" GDP threshold in 2015, and Social Security and Medicare go bust, their wont be an IMF to rescue you. The US is the IMF. No money, no manned expeditions.

The radiation dosage rate on Ganymede is only about eight rem a day. This isn't enough to kill a human, but it would still be wise to stay underground, or at least sheild yourself. On Callisto, Jupiter's radiation belts aren't an issue, being only 0.01 rem a day, which is actually less than normal cosmic-ray doses of .14 rem a day.
