Could Maglev Launches Enable Cheap Access To Space?

With chemical rockets not exactly bringing down the price of space transport, one group of scientists from China have come up with a unique way of reducing the cost of space without losing the ships that bring us there.

(Physorg.com) Most recently, researchers in a group including Wenjiang Yang and his colleagues from the Beijing University of Aeronautics and Astronautics and the Chinese Academy of Sciences have investigated the possibility of the "Maglifter," a maglev launch assist vehicle originally proposed in the 1980s. In this system, a spaceship would be magnetically levitated over a track and accelerated up an incline, lifting off when it reaches a velocity of 1,000 km/hr (620 miles/hr). The main cost-saving areas would come from reduced fuel consumption and the reduced mass of the spaceship.

"Magnetic levitation is a promising technology for future space transportation," Yang told PhysOrg.com. "The most expensive part of space missions to low-Earth orbit is the first few seconds—getting off the ground."

This technology seems very familiar to the magnetic sled (designed by Launch Point), with the only major difference being that humans will be able to ride "this pony."

Although this is not a direct "ground to orbit" launch mechanism, it may drop prices for satellite launches and the space tourism industry, not to mention make constructing a space elevator all the more feasible.
