Soyuz-2 LV Credit: TsSKB

AKA: A-2;Sapwood;SL-4;Soyuz 2;Soyuz FG;Soyuz ST;Soyuz-2-1A. Status: Active. First Launch: 2011-10-21. Last Launch: 2017-01-28. Number: 9 . Payload: 7,800 kg (17,100 lb). Thrust: 4,144.70 kN (931,766 lbf). Gross mass: 310,000 kg (680,000 lb). Height: 43.40 m (142.30 ft). Diameter: 2.95 m (9.67 ft). Apogee: 240 km (140 mi).

Also known as the Soyuz 2, it was a modernization of the Soyuz launcher that increased general performance. The basic launch vehicle design remained the same. Changes were limited to:

• The first and second stage engines featured improved performance with new injectors and mixture ratio.
• The third stage engine performance was increased.
• The launch vehicle was equipped with a new control system allowing in-flight orbital plane change (whereas all earlier R-7 derived vehicles flew a fixed trajectory, with the launch table rotated before launch to the appropriate azimuth).
• A new digital telemetry system provided for launch vehicle monitoring.
• A new, larger-diameter fairing (3.65 meters in diameter) was used.

The standard fourth stage was the Fregat orbital module.

LEO Payload: 7,800 kg (17,100 lb) to a 240 km orbit at 51.80 degrees. Launch Price $: 40.000 million in 1999 dollars.

  European Space Agency Gaia spacecraft to measure the three-dimensional positions and velocities of galactic stars, placed in Lagrangian Point 2. As Gaia rotated, a gigapixel detector array consisting of a complex arrangement of mirrors, CCD's, and photometers measured stellar positions, brightness and color; and Doppler shifts of stars with unprecedented accuracy. The Gaia catalog, when it is available in the 2020's, was expected to put the whole field of astrophysics on a firmer footing. Soyuz ST-B with upper stage Fregat-MT No. 1039 from Kourou-Sinnamary. The Fregat upper stage separated from the Soyuz booster at suborbital velocity. It then made a first burn to a 175 x 175 km parking orbit, then reignited for a 16-minute burn from 09:33 GMT to propel Gaia to a 344 km x 962,690 km x 15.0 deg orbit, on its way to the Sun-Earth L2 point. Gaia fired its own propulsion system of 6 10-N thrusters to raise apogee to around 1.5 million km towards midnight; after a few weeks it entered a Lissajous orbit around the L2 point and began observations. Gaia's data will take years to process and was to result in the best yet catalog of galactic stars.

  Europe's first two Galileo FOC (Full Operational Capability) navigation satellites were put on a suborbital trajectory by the booster. The Fregat-MT No. 1039 upper stage made a first burn to put the stack in elliptical transfer orbit, and then began the coast to apogee. At apogee at 16:05 GMT the Fregat made a second burn intended to circularize the orbit at 23500 km x and 55.0 deg inclination. The satellites separated from the Fregat at 16:15 GMT. Unfortunately the Fregat was wrongly oriented and the orbit actually reached was 13,700 x 25,900 km x 49.7 deg. An attitude control thrusters may have failed during the coast, leaving Fregat pointing the wrong way at second main engine ignition.
