A Russian Soyuz 2-1v lifted off from the Plesetsk Cosmodrome on Saturday, successfully orbiting a satellite and two calibration spheres in the first launch of the new booster.

The “light” launch vehicle, which is designed to lift small payloads, is a significantly modified version of the venerable Soyuz launch vehicle that has been a mainstay of Soviet and Russian space programs since 1966.It maintains a similar outward appearance, but it is very different on the inside.

Modifications include the use of a NK-33 engine in the first stage, the elimination of four first-stage booster rockets, and the use of a Volga upper stage. The NK-33 engines are left over from the Soviet program to land men on the moon, which was canceled in the early 1970’s.

For its maiden launch, the Soyuz 2-1v orbited two SKRL-756 calibration satellites and the AIST-1 micro-satellite.

The new launch vehicle is capable of orbiting payloads weighing between 2,800 to 2,850 kg to low Earth orbit depending whether it is launched from the Plesetsk or Baikonur cosmodromes. Plans call for launching the booster from the new Vostochny spaceport now being constructed in the Russian Far East.

The Soyuz 2-1v was the 80th orbital launch of 2013 worldwide. There are no additional launches planned for the rest of the year.
