Two major discoveries revealed on September 24, 2009 may have made it a lot easier for humans to leave Earth and establish new colonies on the Moon and Mars. In a sensational announcement, NASA announced that there are vast quantities of water on the Moon, which has always been considered an arid world. A second discovery revealed that water ice exists at mid-latitudes on Mars. This is much further from the poles and closer to the equator than water was previously thought to lie and means there should be supplies for human explorers to drink.

Few intresting Questions and Answers on Life in Space -- Part 2
Answered by mission specialist Ron Parise & astronomer Dr. Cathy Imhoff
What kind of training must an astronaut go through?
An astronaut must undergo extensive practice on the experiments that will be operated during the mission; training on living in space like eating, sleeping, going to the bathroom, housekeeping; and emergency procedure practice in case you have to get out in a hurry under many circumstances both on the pad and in flight.
How long does it take to actually get into space after the launch?
It takes 8.5 minutes to reach space after launch.
What does it feel like to be floating?
Wild!!! It is like going down a hill on a roller coaster! Maybe a combination between that and being in a swimming pool without the viscosity of the water
What shape must you be in, physically and mentally?
To be an astronaut you must be in good physical shape (but not an athlete!) and ready to work with the rest of the crew without getting mad at anyone in close quarters over the length of the flight.
How does the pressure in space affect you?
Well, there isn't any pressure, because space is nearly a vacuum. That is one of the reasons that astronauts wear spacesuits.
How can astronauts breathe in the space shuttle?
In order to breathe on the shuttle, they take along a supply of oxygen. There are also filters that take carbon dioxide out of the air. Did you see the movie Apollo 13? One of the biggest dangers for them was that their oxygen tank exploded, and their carbon dioxide filters were clogging up!
When you're out of a spaceship, how do you prevent being sucked into space?
Well, if you are out of the spaceship, you ARE in space. I hope you have your spacesuit on!
