Fairing Jettison |
| After flying through the dense lower atmosphere, the KSLV 1 releases the payload shroud shielding the STSAT 2 spacecraft during the early minutes of the launch. At this point, the KSLV has soared to an altitude of 110 miles and is 152 miles south of the launch pad. |

Stage Separation |
| The first and second stages of the KSLV 1 rocket separate about 200 miles downrange from the launch site. The second stage and STSAT 2 begin a 2 minute, 43 second ballistic phase during which the rocket will coast from an altitude of 122 miles to the injection point about 190 miles high. |

2nd Stage Ignition |
| The solid-fueled second stage, developed in South Korea, ignites for a 58-second burn to accelerate the rocket to orbital velocity. |
|
| T+07:33 |
2nd Stage Cutoff |
| The KSLV 1 rocket's second stage finishes its firing and reaches orbit. Computers are targeting an orbit with a high point of 1,500 kilometers, or 932 miles, and a high point of about 300 kilometers, or 186 miles. |
