Turkey\u2019s most advanced Earth observation satellite will ride a four-stage Vega rocket into polar orbit nearly 435 miles (700 kilometers) above Earth to begin collecting high-resolution images for Turkish military and security authorities.<\/p>\n

The ascent will take nearly an hour following launch from French Guiana at 1351:44 GMT (8:51:44 a.m. EST) Monday.<\/p>\n

\"The
The Vega rocket\u2019s 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.<\/figcaption><\/figure>\n

\"The
The Vega rocket surpasses the speed of sound as it soars on an easterly trajectory from French Guiana. The rocket will reach Max-Q, the point of maximum aerodynamic pressure, at T+plus 53 seconds.<\/figcaption><\/figure>\n

\"Having
Having consumed its 194,000 pounds (88 metric tons) of solid propellant, the 9.8-foot-diameter (3-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 begin its 102-second firing.<\/figcaption><\/figure>\n
