The Space Elevator The Space Elevator is an elevator that would lead to an outer layer outside of earth’s atmosphere. It was designed to create a second “floor” to earth so people could see the wonders of space without a rocket. NASA calls it Millennium-Two Space Elevator. The high of the elevator would be 35,786 km in altitude. It would have electromagnetic vehicles traveling along the cable. To keep it from collapsing they have a large counterbalance mass beyond geostationary orbit. It would have four to six tracks reaching to the top. According to Smitherman, construction is not feasible today but it could be toward the end of the 21st century. "First we'll develop the technology," said Smitherman. "In 50 years or so, we'll be there. Then, if the need is there, we'll be able to do this. That's the gist of the report. Using today's energy costs, researchers figured a 12,000-kg Space Shuttle payload would cost no more than $17,700 for an elevator trip to GEO. A passenger with baggage at 150 kg might cost only $222! "Compare that to today's cost of around $10,000 per pound ($22,000 per kg)," said Smitherman. "Potentially, we're talking about just a few dollars per kg with the elevator." The elevator would go around how fast a space shuttle goes. The elevator would carry people up and down from earth to space. This elevator cannot reach the moon… yet. The designs are very simple as it is one cable up to the base level, one cable car attached to the cable by electromagnets, and a base tower inside earth’s orbit that is connected to the cable. This is designed to make travels to space much less in costs as it takes around 500 million dollars to launch a shuttle when it is around $300 to ride up (and maybe more for luggage). The elevator would be stationed on the equator with a weight to keep it steady. The elevator would be around $450 million in materials and more for
