Russia will develop space elevators

"Scientists from the Space Research Institute of the Russian Academy of Sciences have developed a unique space elevator for lunar and Martian missions. Although a bit slower, the new system will cut back on interplanetary delivery expenses...
... A space elevator consists of satellites, spacecraft and payloads linked by long, thin, flexible elements. The simplest system links two spacecraft by means of a cable with a length of several dozen or even several hundred kilometers. This tandem, which resembles a space sling, revolves around its center of gravity, which in turn has a predetermined orbit. Either of the two spacecraft can therefore launch a payload along any required trajectory without any rocket engines.
The foundations of the space-elevator theory were laid by Russian scientists. Konstantin Tsiolkovsky, the father of astronautics, suggested using a space-tether system to create artificial gravity aboard orbital stations. Fridrikh Tsander, an early Russian space visionary, advocated placing a space elevator with a 60,000-km tether on the Moon. He believed that gravitational and centrifugal forces would stretch the tether and allow it to be used as a cableway to transport payloads. "
