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

\"The
The five main engines of the Soyuz ST-A 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-A (Soyuz 2-1a) rocket soars into the sky from the Guiana Space Center.<\/figcaption><\/figure>\n

T+0:01:57: 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+0:03:16: 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+0:04:47: 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-0110 engine ignites to continue the flight.<\/figcaption><\/figure>\n

T+0:08:49: Soyuz\/Fregat Separation<\/b><\/p>\n

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

T+0:09:49: First Fregat Ignition<\/b><\/p>\n

\"\"
The hydrazine-fueled Fregat upper stage ignites to place the CSG 1 satellite into its targeted sun-synchronous polar orbit.<\/figcaption><\/figure>\n

T+0:20:13: First Fregat Shutdown<\/b><\/p>\n

\"\"
After a 10-minute, 24-second burn, the Fregat upper stage shuts down in preparation for deployment of the Italian CSG 1 radar observation satellite.<\/figcaption><\/figure>\n

T+0:22:43: CSG 1 Separation<\/b><\/p>\n

\"\"
The dual-use CSG 1 radar satellite for Italy separates from the Fregat upper stage in a 384-mile-high (619-kilometer) orbit inclined 97.8 degrees to the equator.<\/figcaption><\/figure>\n

T+1:00:55: Second Fregat Ignition<\/b><\/p>\n

\"\"
The Fregat main engine ignites again for a 12-second burn to maneuver out of the CSG 1 satellite\u2019s orbit in preparation for jettison of the APAS-S multi-payload adapter structure.<\/figcaption><\/figure>\n

T+1:41:40: APAS-S Separation<\/b><\/p>\n

\"\"
The Fregat upper stage jettisons the top of the APAS-S multi-payload adapter structure to reveal the European Space Agency\u2019s CHEOPS satellite for separation.<\/figcaption><\/figure>\n

T+1:52:35: Third Fregat Ignition<\/b><\/p>\n

\"\"
The Fregat main engine ignites for an 11-second burn to maneuver into higher orbit for deployment of ESA\u2019s CHEOPS satellite.<\/figcaption><\/figure>\n

T+2:20:55: Fourth Fregat Ignition<\/b><\/p>\n

\"\"
The Fregat upper stage ignites again for a 26-second burn to place the European Space Agency\u2019s CHEOPS satellite in a 435-mile-high (700-kilometer) orbit with an inclination of 98.2 degrees.<\/figcaption><\/figure>\n

T+2:24:41: CHEOPS Separation<\/b><\/p>\n

\"\"
The European Space Agency\u2019s Characterizing Exoplanet Satellite, or CHEOPS, separates from the Fregat upper stage to begin its three-and-a-half-year mission measuring the sizes of planets around other stars.<\/figcaption><\/figure>\n

T+3:29:15: Fifth Fregat Ignition<\/b><\/p>\n

\"\"
The Fregat main engine ignites for a 16-second burn to begin lowering its orbit for deployment of three European CubeSats.<\/figcaption><\/figure>\n

T+4:02:35: Sixth Fregat Ignition<\/b><\/p>\n

\"\"
The Fregat main engine ignites for a 17-second burn to reach a 310-mile-high (500-kilometer) orbit for separation of three CubeSats.<\/figcaption><\/figure>\n

T+4:10:44: Begin Separation of CubeSats<\/b><\/p>\n

\"\"
The Soyuz mission\u2019s three auxiliary payloads begin their deployment sequence. The OPS-SAT CubeSat from the European Space Agency is a free-for-use, in-orbit testbed for new software, applications and techniques in satellite control. The EyeSat CubeSat from the French space agency, CNES, will observe the zodiacal light and image the Milky Way. The French ANGELS CubeSat carries an Argos data collection payload to relay data from remote weather stations and buoys. All of the CubeSats will be separated from the Fregat upper stage by T+4:13:14, followed by a deorbit burn by the Fregat for a destructive re-entry.<\/figcaption><\/figure>\n
