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+00:01:53 
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 about 33 miles. 

T+00:01:54 
Second Stage Ignition 
The Vega rocket's Zefiro 23 second stage motor fires to begin its 102second burn. 

T+00:03:36 
Second Stage Separation 
The Zefiro 23 motor burns out and jettisons at an altitude of about 93 miles. 

T+00:03:51 
Third Stage Ignition 
Moving at a velocity of nearly 9,000 mph, the Vega rocket's Zefiro 9 motor ignites for the third stage burn.

Fairing Jettison 
The Vega's 8.5footdiameter payload fairing is released as the rocket ascends into the upper atmosphere more than 100 miles high. 

T+00:06:14 
Third Stage Separation 
The Zefiro 9 third stage shuts down and separates, having accelerated the rocket to nearly orbital velocity.

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+00:11:52 
First AVUM Shutdown 
The Vega's AVUM fourth stage is turned off after a 5minute, 31second burn, beginning a 41minute coast until the engine is ignited again. The first AVUM burn places the rocket and its payloads in a parking orbit. 

T+00:52:35 
Second AVUM Ignition 
After coasting to an altitude of about 750 kilometers, or 466 miles, the AVUM fires a second time to circularize its orbit. 

T+00:54:33 
Second AVUM Shutdown 
The AVUM engine shuts down after reaching a circular 466milehigh orbit (750 kilometers) with an inclination of 98.5 degrees.

DZZHR Separation 
The DZZHR satellite is deployed from the Vega rocket's AVUM upper stage.
