National Aeronautics Space Administration competition will draw a number of
international scientists to the New Mexico desert for them to unveil a number of
different revolutionary projects.
The overall goal of the NASA contest is to build some form of a space elevator
that would hopefully one day replace expensive rocket missions. Even though the
idea of a space elevator constructed out of a long enough cable to lift men and
goods into orbit seems a bit outlandish, the entrepreneurs realistically believe
it can be done. University researchers, several corporations and scientists from
several countries will test their devices to at the competition next month. Over
$400,000 in cash prizes will be made available to the winners to the contests.
The key feature of a space elevator would be the use of a satellite that
will orbit almost 23,000 miles above Earth. At this altitude, known as
geostationary orbit, the orbital period of a satellite moving around the globe
matches Earth's rotation. The craft then hovers over a single spot on the
equator. However, a space elevator would have one extra key feature: a massive
cable would be lowered from it to link it to the ground where it would remain
fixed, like a tube line to the stars.
