... there were no gravity, weighted shoes would not help. Every celestial body has a specific escape velocity—this is the speed that needs to be achieved to escape the gravitational pull. For the Earth, this speed is approximately 25,000 miles per hour (mph). For the Moon, it is about 5,300 mph. On the ... asteroid in the solar system, it is about 1,000 mph, so on all of these celestial bodies it would be impossible to move fast enough to just float away.

... first, we likely will use ion propulsion. This is a type of rocket that expels a gas ... fuel, but not very strong. It's like using the highest gear on a bicycle—if you are on level ground, you can get going very fast, but you cannot ... push going for several weeks or months, you can really build up speed to reach Mars in a few weeks instead of six to eight months.

... board games, like the ones you would take with you on a long car trip, would work the same way in space. Magnets and Velcro can both be used to keep the pieces from floating away. Games that use dice wouldn't work because the dice would never ...
... to be sure we don't run out. Eventually we would run out if we somehow lost all the oxygen through a leak, or the systems that make the oxygen failed. But remember, when we fly humans in space we always have systems that have multiple backup systems, so that if something fails we are ready with a backup.

If we were to go into space without a spacesuit (not a very wise decision), we would only survive for a matter of seconds due to lack of air, lack of air pressure, and extreme cold—if we are far away from the ...
