I just read this article from CNN.com:
"Europe readies to shoot for the moon"
http://www.cnn.com/2003/TECH/space/08/19/europe.moon.ap/index.html
According to the article, Europe (which countries do they mean by "Europe"?) will launch an unmanned craft this fall/winter the size of a washing machine to the moon.
It uses an Ion engine (yay!), which CNN says "...build[s] up speed continuously [and] can eventually travel far faster than a craft powered by traditional rocket fuel."
HOWEVER, it will take 18 months to reach the moon! The Apollo missions during the 60s and 70s only took 3 days.
Ion-based engines are awesome, but how long does it take to build up all this "speed"???
I did the math, and SMART-1 (or "SLOW-1" if you prefer :lol: ) will be going 18.4 miles (29.7 kilometers) an hour! Most people can run that fast!
