\"The
The ST-type payload fairing is released from the Soyuz rocket when it reaches the edge of the upper atmosphere. The 13.5-foot-diameter fairing protects the payload during the launch countdown and the flight through the dense lower atmosphere.<\/figcaption><\/figure>\n

The hydrazine-fueled Fregat upper stage ignites to place the SES 15 satellite into a preliminary elliptical transfer orbit.<\/figcaption><\/figure>\n

T+0:23:34: First Fregat Shutdown<\/b><\/p>\n

\"\"
After a 13-minute, 45-second burn, the Fregat upper stage shuts down to begin a 4-hour, 34-minute coast phase.<\/figcaption><\/figure>\n
