First Stage Ignition 
The Vega rocket's first stage P80 solid rocket motor ignites and powers the 98foottall 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 9.8footdiameter 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 103second 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 8.5footdiameter 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 RD869 engine provided by Yuzhnoye of Ukraine. 

T+00:11:22 
First AVUM Shutdown 
The Vega's AVUM fourth stage is turned off after a 5minute burn, beginning a 42minute 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 509milehigh orbit (820 kilometers) with an inclination of 98.7 degrees. 

T+00:55:27 
ProbaV Separation 
The ProbaV 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 liquidfueled fourth stage shuts down and begins a 47minute coast phase. 

T+01:51:25 
Vespa Jettison 
The upper part of the launcher's Vespa dualpayload adapter is jettisoned to reveal the VNREDSat 1 satellite. 

T+01:53:44 
Fourth AVUM Ignition 
The AVUM fourth stage engine fires for a 65second burn. 

T+01:54:49 
Fourth AVUM Shutdown 
The AVUM fourth stage engine shuts down after reaching a circular 413milehigh 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 3pound ESTCube 1 satellite, built by students at the National University of Tartu in Estonia, is deployed from the Vega launcher's fourth stage.
