The Falcon Eye 1 navy reconnaissance satellite tv for pc for the United Arab Emirates is ready to experience a Vega launcher right into a 379-mile-high (611-kilometer) orbit Wednesday evening from French Guiana on a mission that may take lower than one hour from liftoff till spacecraft separation.
Liftoff is scheduled for July 10 at 9:53:03 p.m. EDT (0153:03 GMT on July 11) from the Vega launch pad on the Guiana Area Middle, positioned on the northeastern coast of South America. The Vega launcher, primarily developed and inbuilt Italy, will head north over the Atlantic Ocean to ship the Falcon Eye 1 imaging satellite tv for pc right into a sun-synchronous orbit flying from pole-to-pole.
It will likely be the 15th flight of a Vega rocket, and the second Vega mission of 2019.
T+00:00:00 – Liftoff
The Vega rocket’s first stage P80 strong rocket motor ignites and powers the 98-foot-tall booster off the launch pad zero.Three seconds later. The P80 first stage motor generates a most of 683,00zero kilos of thrust.
T+00:00:31 – Mach 1
The Vega rocket surpasses the velocity of sound because it soars on a northerly trajectory from French Guiana. The rocket will attain Max-Q, the purpose of most aerodynamic strain, at T+plus 53 seconds.
T+00:01:54 – First stage separation
Having consumed its 194,00zero kilos (88 metric tons) of strong propellant, the 9.Eight-foot-diameter (Three-meter) P80 first stage motor is jettisoned at an altitude of about 33 miles (53 kilometers). The second stage Zefiro 23 motor will ignite a second later to start its 103-second firing.
T+00:03:38 – Second stage separation
The Zefiro 23 motor burns out and jettisons.
T+00:03:51 – Third stage ignition
Shifting at a velocity of practically 9,00zero mph, or about Three.9 kilometers per second, the Vega rocket’s Zefiro 9 motor ignites for the third stage burn.
T+00:03:56 – Fairing separation
The Vega’s Eight.5-foot-diameter (2.6-meter) payload fairing is launched because the rocket ascends into house.
T+00:06:32 – Third stage separation
The Zefiro 9 third stage shuts down and separates, having accelerated the rocket to almost orbital velocity.
T+00:08:28 – First AVUM ignition
The Vega rocket’s Angle and Vernier Module, or fourth stage, ignites for the primary time. The AVUM burns hydrazine gasoline with an RD-843 engine supplied by Yuzhnoye of Ukraine.
T+00:16:23 – AVUM first cutoff
The Vega’s AVUM fourth stage is turned off after an 7-minute, 55-second burn, starting an almost 39-minute coast till the engine is ignited once more.
T+00:54:58 – Second AVUM ignition
The AVUM fires a second time for a 69-second burn to place the Falcon Eye 1 satellite tv for pc into its focused orbit.
T+00:56:07 – AVUM second cutoff
The AVUM engine shuts down after reaching a round sun-synchronous orbit with an altitude of 379 miles (611 kilometers).
T+00:57:09 – Falcon Eye 1 separation
The UAE navy’s Falcon Eye 1 statement satellite tv for pc separates from the Vega’s AVUM higher stage.
