Engines at Full Thrust |
The five main engines of the Soyuz rocket's core stage and four strap-on boosters are at full thrust. |
|
T-00:00:00 |
Launch |
Producing more than 900,000 pounds of thrust, the Soyuz 2-1a rocket soars into the sky from the Guiana Space Center. |
|
T+00:01:58 |
Jettison Boosters |
The Soyuz rocket's four strap-on boosters, each powered by an RD-107A engine, are jettisoned after consuming their propellant. |
|
T+00:03:29 |
Jettison Fairing |
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. |
|
T+00:04:47 |
Core Stage Separation |
Having burned its propellant, the core stage of the Soyuz rocket, also known as the second stage, separates and the third stage's RD-0110 engine ignites to continue the flight. |
|
T+00:08:47 |
Soyuz/Fregat Separation |
The Soyuz rocket's third stage releases the Fregat upper stage just shy of orbital velocity. |
|
T+00:09:47 |
First Fregat Ignition |
The hydrazine-fueled Fregat upper stage ignites to place the Pleiades 1, ELISA and SSOT satellites in a low-altitude parking orbit. |
|
T+00:13:27 |
First Fregat Shutdown |
The Fregat upper stage shuts down to begin a coast phase. |
|
T+00:41:56 |
Second Fregat Ignition |
The Fregat stage's main engine fires for a second time to circularize its orbit at nearly 435 miles above Earth. |
|
T+00:46:05 |
Second Fregat Shutdown |
After a 4-minute, 9-second burn, the Fregat upper stage shuts down after entering a circular orbit with an inclination of 98 degrees. |
|
T+00:55:00 |
Pleiades 1 Separation |
The Pleiades 1 satellite separates from the upper position on the Soyuz rocket's APAS-S multi-payload dispenser. |
|
T+00:59:05 |
ELISA Separation |
The four ELISA electronic intelligence satellites deploy simultaneously. |
|
T+02:03:25 |
Third Fregat Ignition |
The Fregat engine ignites for 12 seconds to start lowering its orbit for deployment of Chile's SSOT Earth imaging satellite. |
|
T+02:03:37 |
Third Fregat Shutdown |
The Fregat engine shuts down and enters a 65-minute coast phase. |
|
T+03:08:37 |
Fourth Fregat Ignition |
Another brief Fregat burn begins to position the rocket for separation of the SSOT satellite. |
|
T+03:08:47 |
Fourth Fregat Shutdown |
The Fregat stage engine turns off after reaching a 379-mile-high orbit for the deployment of the SSOT satellite. |
|
T+03:12:07 |
APAS-S Separation |
The APAS-S multi-payload adapter is jettisoned to expose the SSOT satellite for separation. |
|
T+03:26:00 |
SSOT Separation |
Chile's SSOT Earth observation satellite is released to complete the Soyuz rocket's second flight from French Guiana. |
