T-0:00:03: Engines at Full Thrust<\/b><\/p>\n

\"The
The five main engines of the Soyuz rocket\u2019s core stage and four strap-on boosters are at full thrust.<\/figcaption><\/figure>\n

T+0:00:00: Liftoff<\/b><\/p>\n

\"Producing
Producing more than 900,000 pounds of thrust, the Soyuz ST-B (Soyuz 2-1b) rocket soars into the sky from the Guiana Space Center.<\/figcaption><\/figure>\n

T+0:01:58: Jettison Boosters<\/b><\/p>\n

\"The
The Soyuz rocket\u2019s four strap-on boosters, each powered by an RD-107A engine, are jettisoned after consuming their propellant.<\/figcaption><\/figure>\n

T+0:03:39: Jettison Fairing<\/b><\/p>\n

\"The
The ST-type payload fairing is released from the Soyuz rocket when it reaches the edge of the upper atmosphere. The 13.5-foot-diameter fairing protects the payload during the launch countdown and the flight through the dense lower atmosphere.<\/figcaption><\/figure>\n

T+0:04:48: Core Stage Separation<\/b><\/p>\n

\"Having
Having burned its propellant, the core stage of the Soyuz rocket, also known as the second stage, separates and the third stage\u2019s RD-0124 engine ignites to continue the flight.<\/figcaption><\/figure>\n

T+0:09:24: Soyuz\/Fregat Separation<\/b><\/p>\n

\"The
The Soyuz rocket\u2019s third stage releases the Fregat-MT upper stage just shy of orbital velocity.<\/figcaption><\/figure>\n

T+0:10:24: First Fregat Ignition<\/b><\/p>\n

\"The
The hydrazine-fueled Fregat upper stage ignites to place the Galileo satellites in an elliptical transfer orbit.<\/figcaption><\/figure>\n

T+0:23:32: First Fregat Shutdown<\/b><\/p>\n

\"After
After a 13-minute, 8-second burn, the Fregat upper stage shuts down to begin a 3-hour, 15-minute coast phase.<\/figcaption><\/figure>\n

T+3:38:35: Second Fregat Ignition<\/b><\/p>\n

\"The
The Fregat main engine ignites to circularize its orbit before deployment of the two Galileo satellites.<\/figcaption><\/figure>\n

T+3:42:57: Second Fregat Shutdown<\/b><\/p>\n

\"The
The Fregat main engine shuts down after a 4-minute, 22-second burn to inject the Galileo satellites into a circular orbit at an altitude 23,522 kilometers (14,615 miles) and an inclination of 57.39 degrees.<\/figcaption><\/figure>\n

T+3:47:57: Galileo Separation<\/b><\/p>\n

\"The
The two Galileo navigation satellites deploy from a dispenser on the Fregat upper stage.<\/figcaption><\/figure>\n
