First Stage Ignition |
The Vega rocket's first stage P80 solid rocket motor ignites and powers the 98-foot-tall booster off the launch pad 0.3 seconds later. The P80 first stage motor generates a maximum of 683,000 pounds of thrust. |

Mach 1 |
The Vega rocket surpasses the speed of sound as it soars on a northerly trajectory from French Guiana. |
|
T+00:00:53 |
Maximum Dynamic Pressure |
Flying at an altitude of more than 40,000 feet, the rocket passes through the phase of maximum aerodynamic pressure. |
|
T+00:01:56 |
First Stage Separation |
Having consumed its 194,000 pounds of solid propellant, the 9.8-foot-diameter P80 first stage motor is jettisoned at an altitude of 33 miles. |
|
T+00:01:57 |
Second Stage Ignition |
The Vega rocket's Zefiro 23 second stage motor fires to begin its 103-second burn. |
|
T+00:03:40 |
Second Stage Separation |
The Zefiro 23 motor burns out and jettisons at an altitude of 93 miles. |
|
T+00:03:55 |
Third Stage Ignition |
Moving at a velocity of nearly 8,800 mph, the Vega rocket's Zefiro 9 motor ignites for the third stage burn. |
|
T+00:04:00 |
Fairing Jettison |
The Vega's 8.5-foot-diameter payload fairing is released as the rocket ascends into the upper atmosphere more than 104 miles high. |
|
T+00:06:19 |
Third Stage Separation |
The Zefiro 9 third stage shuts down and separates, having accelerated the rocket to nearly orbital velocity. |
|
T+00:06:26 |
First AVUM Ignition |
The Vega rocket's Attitude and Vernier Module, or fourth stage, ignites for the first time. The AVUM burns hydrazine fuel with an RD-869 engine provided by Yuzhnoye of Ukraine. |
|
T+00:11:22 |
First AVUM Shutdown |
The Vega's AVUM fourth stage is turned off after a 5-minute burn, beginning a 42-minute coast until the engine is ignited again. The first AVUM burn places the rocket and its payloads in a parking orbit. |
|
T+00:53:05 |
Second AVUM Ignition |
After coasting to an altitude of 500 miles, the AVUM fires a second time to circularize its orbit. |
|
T+00:54:37 |
Second AVUM Shutdown |
The AVUM engine shuts down after reaching a circular 509-mile-high orbit (820 kilometers) with an inclination of 98.7 degrees. |
|
T+00:55:27 |
Proba-V Separation |
The Proba-V satellite is deployed from the Vega rocket's AVUM upper stage. |
|
T+01:04:13 |
Third AVUM Ignition |
The AVUM fires a third time to modify its orbit for deployment of the VNREDSat 1 satellite. |
|
T+01:04:35 |
Third AVUM Shutdown |
The Vega rocket's AVUM liquid-fueled fourth stage shuts down and begins a 47-minute coast phase. |
|
T+01:51:25 |
Vespa Jettison |
The upper part of the launcher's Vespa dual-payload adapter is jettisoned to reveal the VNREDSat 1 satellite. |
|
T+01:53:44 |
Fourth AVUM Ignition |
The AVUM fourth stage engine fires for a 65-second burn. |
|
T+01:54:49 |
Fourth AVUM Shutdown |
The AVUM fourth stage engine shuts down after reaching a circular 413-mile-high orbit (665 kilometers) with an inclination of 98.1 degrees. Another AVUM firing is planned to deorbit the stage after separation of VNREDSat 1 and ESTCube 1. The AVUM stage is designed for up to five burns in a mission. |
|
T+01:57:24 |
VNREDSat 1 Separation |
Vietnam's VNREDSat 1 Earth observation satellite is released from the Vega rocket. |
|
T+02:00:48 |
ESTCube 1 Separation |
The 3-pound ESTCube 1 satellite, built by students at the National University of Tartu in Estonia, is deployed from the Vega launcher's fourth stage. |
