NASA explores electromagnetic space launches CNN

Researchers at NASA are looking into whether electromagnets can be used to send rockets into space, a technological leap that could dramatically cut launch costs. Spacecraft burn hundreds of thousands of gallons of fuel to reach orbit. But rocket engineers at the Marshall Space Flight Center are investigating whether electromagnetic power can do the job. It would be a much cleaner and safer method of launching vehicles, and much cheaper. NASA hopes to drive down the cost of rocket departures from $10,000 per pound to $1,000 per pound.
